Since the S7-300 components only contain low levels of harmful substances, they are
suitable for recycling. For ecologically compatible recycling and disposal of your old device,
contact a certificated disposal service for electronic scrap.
Note on IT security
Siemens offers IT security mechanisms for its automation and drive product portfolio in order
to support the safe operation of the plant/machine. We recommend that you inform yourself
regularly on the IT security developments regarding your products. You can find information
on this on the Internet (http://support.automation.siemens.com).
You can register for a product-specific newsletter here.
For the safe operation of a plant/machine, however, it is also necessary to integrate the
automation components into an overall IT security concept for the entire plant/machine,
which corresponds to the state-of-the-art IT technology. You can find information on this on
the Internet (http://www.siemens.com/industrialsecurity).
Products used from other manufacturers should also be taken into account here.

SIPLUS S7-300 Modules
Definition
SIPLUS S7-300 modules can be used under extended environmental conditions. Meaning of
"extended environmental conditions":
● Extended temperature range of - 25 °C to + 60 °C/70°C
● Moisture condensation/condensation permissible
● increased mechanical stress permissible
Comparison with "standard" modules
The functional scope and technical data of SIPLUS S7-300 modules and of "standard"
modules are identical, with the exception of the environmental conditions.
SIPLUS S7-300 modules have a separate order number (see the table below.)
The mechanical/climatic environmental conditions and the method of testing these have
changed. The SIPLUS S7-300 modules are specified:
● For deployment in harsh environmental conditions,
● For use in hostile environments.
● For extreme temperature ranges.
For more detailed information on this, refer to section Environmental conditions for the
operation of SIPLUS S7-300 modules (Page 29).
Project design in STEP 7
SIPLUS S7-300 modules are not included in the hardware catalog. Please design your plant
based on the relevant "standard" modules shown in the table below.

Programming digital modules
Introduction
Digital modules may have different properties. You can program the properties of certain
modules.
All information in this chapter applies only to programmable digital modules:
● Digital input module SM 321; DI 16 x DC 24 V with process and diagnostic interrupts,
isochronous; (6ES7321-7BH01-0AB0)
● Digital input module SM 321; DI 16 x DC 24 V/125 V with process and diagnostic

● Digital input/output module SM 327; DI 8/DO 8 x DC 24 V/0,5 A (6ES7327-1BH00-0AB0)
Programming tools
Only program the digital modules in STEP 7 while the CPU is in STOP.
After you defined all parameters, download these from your PG to the CPU. During its STOP
→ RUN transition, the CPU transfers the parameters to the relevant digital modules.
Static and dynamic parameters
Parameters are organized by static and dynamic properties.
Set the static parameters while the CPU is in STOP, as described earlier.
You may also edit dynamic parameters in the active user program of an S7 PLC using SFCs.
However, the parameters set in STEP 7 will be applied again after a RUN → STOP, STOP →
RUN transition of the CPU. The appendix Parameter sets of the signal modules (Page 549)
describes the assignment of module parameters in the user program.

Diagnostics of digital modules
Introduction
The information provided in this chapter applies only to S7-300 digital modules with
diagnostics functions.
● Digital input module SM 321; DI 16 x DC 24 V with process and diagnostic interrupts,
isochronous; (6ES7321-7BH01-0AB0)
● Digital input module SM 321; DI 16 x DC 24 V/125 V with process and diagnostic
interrupts (6ES7321-7EH00-0AB0)
● Digital output module SM 322; DO 16 × UC 24/48 V (6ES7322-5GH00-0AB0)
● Digital output module SM 322; DO 16 x DC 24 V/0,5 A (6ES7322-8BH10-0AB0)
● Digital output module SM 322; DO 8 x DC 24 V/0,5 A with diagnostic interrupt
(6ES7322-8BF00-0AB0)
● Digital output module SM 322; DO 8 x AC120/230 V /2A ISOL (6ES7322-5FF00-0AB0)
● Digital output module SM 322; DO 8 x Rel. AC230V /5A (6ES7322-5HF00-0AB0)
Programmable and non-programmable diagnostics messages
We distinguish between programmable and non-programmable diagnostics messages.
You only obtain programmable diagnostics messages if you have enabled diagnostics at the
relevant parameters. Program the "Diagnostics" parameter block in STEP 7.
Digital modules always return non-programmable diagnostics messages, irrespective of
diagnostics being enabled.
Reactions to diagnostics message in STEP 7
Actions initiated by diagnostics messages:
● The diagnostics message will be entered in the diagnostics data of the digital module,
and is then passed to the CPU.
● The SF LED on the digital module is lit.
● When "Enable Diagnostics Interrupt" is set in STEP 7, the system triggers a diagnostics
interrupt and calls OB82.

3.4 Diagnostics of digital modules
Reading diagnostics messages
You can read detailed diagnostics messages using SFCs in the user program (refer to the
appendix Diagnostics data of signal modules (Page 609)).
In STEP 7, you can view the cause of error by reading the module diagnostics data (refer to
the STEP 7 Online Help.)
Diagnostics message using the SF LED
Digital modules with diagnostics function indicate errors at their SF LED (group error LED.)
The SF LED lights up when the digital module generates a diagnostics message. It goes
dark after all error states are cleared.
The SF LED also lights up to indicate external errors (short-circuit at the sensor supply),
regardless of the CPU operating state (at POWER ON.)
Diagnostics messages and interrupt processing of digital modules
For information on diagnostics messages, their possible causes, troubleshooting measures,
and possible interrupts refer to the specific module chapter.

3.5 How to protect digital modules from inductive overvoltage
3.5
How to protect digital modules from inductive overvoltage
Inductive overvoltage
Overvoltage occurs when an inductance is deactivated. Examples of this are relay coils and
contactors.
Integrated overvoltage protection
The digital output modules of S7-300 have integrated overvoltage protection equipment.
Extra overvoltage protection
Inductances should only be configured with extra overvoltage protection equipment in the
following instances:
● If SIMATIC output current circuits can be deactivated by extra fitted contacts (e.g. relay
contacts).
● If the inductive reactances are not activated by SIMATIC modules.
Note: Ask the suppliers of inductive reactances what size of overvoltage protection
equipment should be used.
Example
The following diagram shows an output current circuit which make extra overvoltage
protection equipment necessary.

Configuration of coils operated with direct current
Properties of the diode/Z diode circuit:
● Cut-off currents can be avoided. Z diode withstands a higher cut-off voltage.
● High cut-off delay (6 to 9 times higher compared to non-protective cid´rcuits).
Faster cut-off of the Zener diode compared to the diode circuit.
Connection of AC-operated coils
The operation of AC coils with varistors or RC elements is shown in the diagram.

Properties of a circuit with varistor:
● The amplitude of the cut-off current is limited but not attenuated.
● The steepness of the overvoltage remains the same.
● Low cut-off delay.
Properties of acircuit with RC elements:
● Reduction of the amplitude and steepness of the cut-off current.
● Low cut-off delay.

3.11.1
Isochronous mode
Properties
Reproducible reaction times (i.e. of the same length) are achieved in a SIMATIC system by
means of a constant DP bus cycle, and synchronization of the single cyclic processes
outlined below:
● Independent user program cycle. The length of the cycle time may vary due to non-cyclic
program branching.
● Independent and variable DP cycle on the PROFIBUS subnet
● Cyclic operation of the backplane bus of the DP slave.
● Cyclic signal conditioning and conversion at the electronic modules of the DP slave.
The constant DP cycle runs in synchronism and at the same length. The CPU run levels
(OB61 to OB64) and isochronous IO are synchronized with this cycle. I/O data are therefore
transferred at defined and constant intervals (isochronous mode.)
Requirements
● The DP master and slave must support isochronous mode. STEP 7 V5.2 or higher.
Operating mode: Isochronous mode
Conditions of isochronous mode:
Filtering and processing time TWE between reading actual values and writing these to the
transfer buffer(the value defined for TWE applies, irrespective of the enable status of diagnostics)
255 μs to 345 µs
includes an input delay time of
100 µs
TDPmin
2.5 ms
Diagnostic interrupt
max. 4 x TDP
Note
In "isochronous" mode, the input delay is automatically set to 100 μs, regardless of the input
delay setting in STEP 7
Further information
For further information on isochronous mode, refer to the STEP 7 Online Help, in the
operating instructions ET 200M Distributed IO System
(http://support.automation.siemens.com/WW/view/en/1142798) and in tthe Synchronicity

Wire break diagnostics
Wire break diagnostics is always used for one channel group with two channels. It is only
possible to determine that one of the two channels has suffered a wire break; it is not
possible to identify which one. When operated with PCS7, only one channel of the group can
be used at any time for an exact diagnosis.

Reaction to power failure
Failure of the SM 321; DI 16 x DC 24 power supply is always indicated by the module's SF
LED. This information is also available on the module.
The input value is initially held for the duration of 20 ms to 40 ms before the zero signal is
transferred to the CPU. Supply voltage dips <20 ms do not influence the process value (see
the table above.)
Triggering of diagnostic interrupts is determined by the parameter settings (see chapter
Interrupts of SM 321; DO 16 x DC 24 V (Page 96)).
Power supply failure with redundant external sensor supply
Note
When an external redundant power source is connected in parallel to the sensor supply (Vs)
and the L+ power supply fails, the module does not report failure of the sensor supply, but
rather the failure of the internal and/or external auxiliary voltage, and/or a blown fuse.
Short-circuit at the sensor supply Vs
The relevant Vs LED goes dark if a short-circuit is detected at the sensor supply Vs,
irrespective of parameter settings.

SM 321; DI 16 x DC 24 V - Interrupts
Introduction
This chapter describes the interrupt reaction of SM 321; DI 16 x DC 24 V. Always distinguish
between the following interrupts:
● Diagnostic interrupt
● Hardware interrupt
For detailed information on the OBs and SFCs mentioned below, refer to the STEP 7 Online
Help.
Enabling interrupts
There is no default interrupt setting, i.e. interrupts are disabled if parameters are not set
accordingly. You can enable interrupts in STEP 7 (see the chapter Parameters of SM 321;
DI 16 x DC 24 V (Page 91)).
Diagnostic interrupt
When diagnostic interrupts are enabled, incoming error events (initial occurrence) and
outgoing error events (error is cleared) are reported by means of an interrupt.
The CPU interrupts user program execution in order to process diagnostic interrupt OB82.
You can call SFC51 or 59 in OB82 in the user program to view detailed diagnostics data
output by the module.
Diagnostics data remain consistent until the program exits OB82. The module acknowledges
the diagnostic interrupt when the program exits OB82.
Hardware interrupt
SM 321; DI 16 x DC 24 V can trigger a hardware interrupt for each channel group at the
positive, negative, or both edges of a signal transition.
Program each channel group separately. The parameters can be changed at any time
(in RUN mode in the user program.)
Active hardware interrupts trigger hardware interrupt processing in the CPU (OB40) and
interrupt execution of the user program or of object classes with lower priority in the CPU.
You can define the response of the AS to signal edge transitions in the user program of
hardware interrupt OB40. The module acknowledges the hardware interrupt when the
program exits the hardware interrupt OB.
The module can save one interrupt per channel to the stack. If no higher priority classes are
pending processing, the CPU processes the buffered interrupts (of all modules) in the order
of their occurrence.

Digital modules
3.11 Digital input module SM 321; DI 16 x 24 VDC; with hardware and diagnostic interrupts (6ES7321-7BH01-0AB0)
Hardware interrupt lost
A "Hardware interrupt lost" diagnostic interrupt is generated if a successive interrupt is
triggered at the channel previously saved to the stack and which has not yet been processed
by the CPU.
The CPU does not register any further interrupts at this channel unless it has completed
processing of the queued interrupts of the same channel.
Interrupt-triggering channels
The relevant hardware interrupt-triggering channel is logged in the OB40_POINT_ADDR
variable of the start information of OB40. The figure shows the bit assignments of DWORD 8
in the local data.

Special features of diagnostics
The SM 321; DI 16 x DC 24 V/125 V supplies 9-byte diagnostic data (diagnostic data set 0
with a length of 4 bytes and the diagnostic data set 1 with a length of 9 bytes).
The wire-break diagnostics is only reported in the channel error vector of the data set 1
(bytes 7 and 8). Each channel that reports an error in the channel errror vector has a wirebreak. You can find additional information, in chapter Structure and content of diagnostics
data, byte 0 and up (Page 610).

Interrupts of SM 321; DI 16 x DC 24/125 V
Introduction
This chapter describes the interrupt reaction of SM 321; DI 16 x DC 24 V/125V. Always
distinguish between the following interrupts:
● Diagnostic interrupt
● Hardware interrupt
For detailed information on the OBs and SFCs mentioned below, refer to the STEP 7 Online
Help.
Enabling interrupts
There is no default interrupt setting, i.e. interrupts are disabled if parameters are not set
accordingly. You can enable interrupts in STEP 7 (see the chapter Parameters of SM 321;
DI 16 x DC 24 V ).
Diagnostic interrupt
When diagnostic interrupts are enabled, incoming error events (initial occurrence) and
outgoing error events (error is cleared) are reported by means of an interrupt.
The CPU interrupts user program execution in order to process diagnostic interrupt OB82.
You can call SFC51 or 59 in OB82 in the user program to view detailed diagnostics data
output by the module.
Diagnostics data remain consistent until the program exits OB82. The module acknowledges
the diagnostic interrupt when the program exits OB82.
Hardware interrupt
SM 321; DI 16 x DC 24 V/125V can trigger a hardware interrupt for each channel group at
the positive, negative, or both edges of a signal transition.
You perform parameter assignment for each channel separately. The parameters can be
changed at any time (in RUN mode in the user program.)
Active hardware interrupts trigger hardware interrupt processing in the CPU (OB40) and
interrupt execution of the user program or of object classes with lower priority in the CPU.
You can define the response of the AS to signal edge transitions in the user program of
hardware interrupt OB40. The module acknowledges the hardware interrupt when the
program exits the hardware interrupt OB.
The module can save one interrupt per channel to the stack. If no higher priority classes are
pending processing, the CPU processes the buffered interrupts (of all modules) in the order
of their occurrence.

Digital modules
3.24 Digital output module SM 322; DO 16 x DC 24 V/0.5 A: (6ES7322-8BH10-0AB0)
Using the module
For the use of the SM 322; DO 16 x DC24V/0.5A, the following hardware and software
requirements must be fulfilled:
● For the central use in S7-300, the module can be used with all available CPUs.
● For the decentral use in ET 200M, the module can be used with the following
IM 153-modules and compatible successor modules:
– IM 153-2; as of 6ES7153-2BA02-0XB0, (PROFIBUS).
– IM 153-2; as of 6ES7153-2BA82-0XB0; (PROFIBUS, OUTDOOR).
– IM 153-4; as of 6ES7153-4BA0x-0XB0; (PROFINET).
● Requirement: STEP 7 V5.5 (HSP0217) or higher.
● A GSD file or a GSDML file must be used if the module is part of a distributed and
controlled by a master produced by a third-party manufacturer. The corresponding file for
the selected IM 153 is available for download from the Internet
(http://www.siemens.com/automation/service&support).
● Module diagnosis and identification data (I&M) are available through STEP 7 and with
SIMATIC PDM as of V6.0 + SP5 (HSP0217) or SIMATIC PDM V7.0 or higher and EDD
for ET 200M "DP_IOSystem_Siemens_ET200M_Module.Device" as of V1.1.12.
Compatible use of the module 6ES7322-8BH0x-0AB0
You can repalce the digital output module 6ES7322-8BH0x-0AB0 without changing your
settings through a digital output module 6ES7322-8B10-0AB0.
In this case, the module does not offer discrepancy failure monitoring.
If a STEP 7 version before STEP 7 V5.1 SP3 is used, the replacement value behavior will
only be entered through the parameter dialog from HW config and transferred to the module
during system startup.
In this case, all other settings must be transferred through SIMATIC PDM or in the user
program through datasets to the module.
These settings are not saved retentively on the digital output module 6ES7322-8BH10-0AB0
and are reset after restarting the module.
Note
A setting through SIMATIC PDM is only possible with the use of a 6ES7322-8BH10-0AB0
as a replacement for a 6ES7322-8BH0x-0AB0 as long as the device label
(6ES7322-8BH0x-0AB0) in SIMATIC PDM was not updated with the actual device label
through Device -> Load in PC/PG.
Redundant use of the module
A redundant use of the module is only permissible if the 6ES7322-8BH10-0AB0 is used and
configured for both modules. No short-circuit monitoring occurs according to L+ in redundant
use.

Load resistances of the actuators
The load resistances of the actuators must be in the range from 48 Ω to 4 Ω. For larger
values, a suitable resistance must be switched directly on the connection clamps of the
actuator (observe the maximum power loss with signal "1").
The permissible rated voltage of the actuator must be greater than 28.2 V.
The lower response threshold of the actuator must be known in the operating temperature
range or be determined experimentally. The output voltage of the module with signal "0" can
be influenced through parallel switching of a resistance directly on the actuator connection
clamps. With the selection of the resistance, the maximum power loss with signal "1" must
be observed.
● Load resistances between 10 kΩ and 1 MΩ can be reported as short-circuits after L+.
● Unwired outputs or loads greater than 1 MΩ are reporeted as "wire-break".

Diagnosis of digital output modules
Introduction
General information in regards to the evaluation of the diagnosis messages can be found in
the chapter Diagnosis of digital modules (Page 60) and the design and content of the
individual bytes in the chapter Diagnosis data from the SM 322; DO 16 x DC24 V/0.5 A
(6ES7322-8BH10-0AB0) (Page 616).
Channel errors are signaled with the channel error display (red LED per channel) and
reported in the data record 1. As soon as at least one channel error display is lit, the group
error display (SF) is also lit.
Module errors are signaled via the diagnostic data record 0/1 and only displayed via the the
group error display (SF).
Group diagnostics
Through the "Group diagnositcs" setting, the message from the channel-specific fields, with
the exception of "external load voltage L+", for "Setting error" and the recognition of a
discrepancy error can be turned off.
Load voltage L+ missing
The approval of the channel diagnositcs "external load point L+" occurs in channel groups
through the diagnostics setting "Missing load voltage L+". This means that if the load voltage
fails, the error will be reported to all four channels of a channel group. Additionally, the
module-specific message occurs in the byte 0 of the diagnostics dataset 0 / 1, "external
auxiliary voltage missing". Even if the diagnostics of "Missing load voltage L+" is turned off
for all channels/channel groups, the recognition within the module remains active. This
means that if there is a failure of at least one load voltage, the module error will always be
reported in the byte 0 of the diagnostics data set 0 / 1 "External auxiliary voltage missing".
Fuse blown
If a fuse is blown, it will always be reported to all four channels of a channel group. In
addition to the channel message, there is always the module-specific message in the byte 3
of the diagnostics dataset 0 / 1 "Fuse defect". Even if the "Group diagnostics" setting is
disabled by all channels, a defective fuse will always be reported as module error in the byte
3 of the diagnostics dataset 0 / 1 "Fuse defect".

Digital modules

Discrepancy error monitoring
For project engineering with the MLFB 6ES7322-8BH10-0AB0, the SM 322
DO 16 x DC24 V / 0.5A offers a discrepancy error monitoring.
The approval of the channel discrepancy error monitoring occurs in channel groups through
the "Discrepancy error" diagnostics settings. With an approved discrepancy error monitoring,
the module constantly checks the set and actual status of the corresponding digital outputs.
With a recognized discrepancy, for example, due to a component defect on the digital
module, the corresponding channel group will be turned off and the "Fuse defect" error will
be reported to all affected channels in the channel group. After removal/insertion or restart of
the module, the digital outputs will be reactivated and the discrepancy test runs again.
A discrepancy error is exclusively reported through the "Fuse defect" error. An additional
indication through the byte 3 "Fuse defect" does not occur. Thus, a differentiation between
the actual fuse blown and a discrepancy error is possible.
Description of the Diagnostic Evaluation
You can find a detailed description of how to evaluate diagnostic information in the STEP 7
online help.

Firmware update via HW Config
Introduction
The SM 322; DO 16 x DC 24V/0.5 A can be updated to the newest firmware version
depending on the available compatible functional updates.
The most recent firmware versions are available from your Siemens representative or from
the Internet (http://www.siemens.com/automation/service&support).
Preconditions / Requirements
● STEP 7 V5.5 +(HSP0217) or higher
● With a central use of the module in a S7-300, the firmware update must occur in the
CPU-operating mode STOP. If the CPU is in the operating mode RUN, it may lead to
unexpected behavior and the module is only available after a network off/network on.
● If the module is used in a distributed IO device ET 200M with active backplane bus
modules (removal and insertion allowed), the a firmware update is also possible in the
RUN CPU state.
● With a distributed use without active backplane bus modules, the firmware update is also
possible in the RUN CPU state. Please observe that during the firmware update, the
distributed IO device will be turned off shortly.
Firmware update
This is how you update the firmware of a central or distributed module:
1. Select the module SM 322; DO 16 x DC 24V/0.5 A in HW-config.
2. Select PLC > Update Firmware.
3. Use the "Browse" button to select the path to the firmware files (*.upd).
4. Click the "Run" button.
– The module performs the firmware update.
5. You can find additional information in the STEP 7 Online Help.
Note
• During the firmware update, the OB 83 (alarm due to removing and inserting
modules), the OB 85 (program execution error) and the OB 86 (error due to module
rack failure) are opened. If the diagnostics alarm of the module is approved, the OB 82
(diagnostics alarm) will also be opened during the firmware update. Make sure that the
OB is set correspondingly.
• If the red LED (SF) on the module blinks, an error occurred during the firmware update
and the update must be repeated. In this case, the bootloader version Ex.x.x is
displayed in the online diagnostics.
• A firmware update through HW-config is not permitted if the module is in redundant
mode.

SM 322; DO 8 x DC 24 V/0.5 A - Interrupts
Introduction
The SM 322; DO 8 x DC 24 V/0.5 A can trigger diagnostic interrupts.
For detailed information on the OBs and SFCs mentioned below, refer to the STEP 7 Online
Help.
Enabling interrupts
There is no default interrupt setting, i.e. interrupts are disabled if parameters are not set
accordingly. Program the interrupt enable parameter in STEP 7.
Diagnostics interrupt
Incoming error events (initial occurrence) and outgoing error events (error is cleared) are
reported by means of diagnostics interrupt, if this interrupt is enabled.
The CPU interrupts user program execution in order to process diagnostics interrupt OB82.
You can call SFC51 or 59 in OB82 in the user program to view detailed diagnostics data
output by the module.
Diagnostics data remain consistent until the program exits OB82. The module acknowledges
the diagnostics interrupt when the program exits OB82.

SM 322; DO 8 x AC 120/230 V/2 A ISOL - Interrupts
Introduction
The SM 322; DO 8 x AC 120/230 V/2 A ISOL can trigger diagnostic interrupts.
For detailed information on the OBs and SFCs mentioned below, refer to the STEP 7 Online
Help.
Enabling interrupts
There is no default interrupt setting, i.e. interrupts are disabled if not set accordingly.
Program the interrupt enable parameter in STEP 7.
Diagnostic interrupt
When diagnostic interrupts are enabled, incoming error events (initial occurrence) and
outgoing error events (error is cleared) are reported by means of interrupt.
The CPU interrupts user program execution in order to process diagnostics interrupt OB82.
You can call SFC51 or 59 in OB82 in the user program to obtain detailed diagnostics data
from the module.
Diagnostics data remain consistent until the program exits OB82. The module acknowledges
the diagnostic interrupt when the program exits OB82.
Load restrictions in horizontal mounting position
In horizontal mounting position, the module loads must be restricted so that two adjacent
inputs or outputs do not exceed their rated load.
Load restrictions in vertical mounting position
In vertical mounting position, the module loads must be restricted so that four adjacent inputs
or outputs do not exceed their rated load.

Operation on safety extra-low voltage (SELV)
Make allowances for the special feature outlined below when operating the
6ES7322-5HF00-0AB0 relay output module on SELV:
The horizontally adjacent terminal of a terminal operated on SELV may not be operated at a
rated voltage higher than 120 VUC. When operated at voltages higher than 120 VUC, the
creepage distances and air gaps in the 40-pin front connector do not meet SIMATIC
requirements of safe electrical separation.
①
If one of two horizontally adjacent terminals is operated on SELV, the other terminal may not be
operated at more than 120 VUC.

SM 322; DO 8 x Rel. AC 230V/5A - Interrupts
Introduction
The SM 322; DO 8 x Rel. AC 230V/5A can trigger diagnostic interrupts.
For detailed information on the OBs and SFCs mentioned below, refer to the STEP 7 Online
Help.
Enabling interrupts
There is no default interrupt setting, i.e. interrupts are disabled if not set accordingly.
Program the interrupt enable parameter in STEP 7.
Diagnostic interrupt
Incoming error events (initial occurrence) and outgoing error events (error is cleared) are
reported by means of diagnostics interrupt, if this interrupt is enabled.
The CPU interrupts user program execution in order to process diagnostics interrupt OB82.
You can call SFC51 or 59 in OB82 in the user program to obtain detailed diagnostics data
from the module.
Diagnostics data remain consistent until the program exits OB82. The module acknowledges
the diagnostics interrupt when the program exits OB82.

Operation on safety extra-low voltage (SELV)
Make allowances for the special feature outlined below when operating relay output module
322-1HF10 on SELV:
To operate a terminal on SELV, the horizontally adjacent terminal may not be operated at a
rated voltage higher than 120 VUC. The creepage distances and air gaps of the 40-pin front
connector do not meet SIMATIC requirements in terms of safe electrical separation if
operated with voltages above 120 VUC.
①
If one of two horizontally adjacent terminals is operated on SELV, the other terminal may not be
operated at more than 120 VUC.

Overview
Introduction
This chapter describes the basic procedure in wiring and connecting signal sensors to
analog inputs and analog outputs and corresponding items to observe.
The diagrams below do not show the connecting lines required to connect the electrical
potentials of the analog input module and sensors.
Always adhere to the general information on sensor wiring and connecting.
Special wiring and connecting options are described in the corresponding module data.
Installation and wiring
For information on installation and wiring, refer to the S7-300, CPU 31xC, and CPU 31x
Operating Instructions: Installation The operating instructions are available on the Internet
(http://support.automation.siemens.com/WW/view/en/13008499).

Principles of analog value processing
4.2 Wiring and connecting transducers to analog inputs
4.2
Wiring and connecting transducers to analog inputs
Transducers which can be wired and connected to analog inputs
You can wire and connect the following transducers to the analog input modules, depending
on the type of measurement:
● Voltage transducers
● Current transducers
– As 2-wire transducer
– As 4-wire transducer
● Resistors
● Thermocouples
Cables for analog signals
Always use shielded twisted-pair cables to wire analog signals. This reduces interference.
Connect both ends of the analog cable shield to ground.
Any potential difference between the cable ends may cause an equipotential current on the
shield and disturbance on analog signals. Avoid this effect by means of low-impedance
equipotential bonding. Ground only one end of the shielding.
Electrically isolated analog input modules
Electrically isolated analog input modules are not electrically interconnected at the reference
point of the measuring circuit (MANA and/or M) and the M terminal of the CPU/IM153.
Always use electrically isolated analog input modules if there is any risk of potential
difference VISO developing between the reference point of measuring circuit (MANA and/or
M-) and the M terminal of the CPU/IM153 .
You can prevent the potential difference V ISO from exceeding limits by means of
equipotential interconnection of terminals MANA and M of the CPU/IM153.
Non-isolated analog input modules
Non-isolated analog input modules require a low-impedance connection between the
reference point of measuring circuit MANA and the M terminal of the CPU or interface module
IM 153. Interconnect terminals MANA with M of the CPU or interface module IM 153. Any
potential difference between MANA and M of the CPU or interface module IM 153 may corrupt
the analog signal.

4.2 Wiring and connecting transducers to analog inputs
Limited potential difference CMV
The permissible potential difference UCM (CMV/Common Mode) may not be exceeded. A
CMV fault may develop between
● the measurement inputs (M+ / M-) and the reference potential of measuring circuit MANA
● between the measuring inputs.
The following diagrams show the measures to be taken when wiring transducers.
4.2.1
Wiring and connecting electrically isolated transducers
Electrically isolated transducers
Electrically isolated transducers are not connected to local ground potential. They can be
operated in electrically isolated mode.
Potential differences may develop between electrically isolated sensors. These potential
differences may be caused by interference, or may develop as a result of the local
distribution of transducers.
In environments with a high level of EMC interference, it is advisable to interconnect M- with
MANA in order to prevent the permissible CMV value from being exceeded.
Note
For modules where VCM ≤ 2.5 V, interconnect M- and MANA (see the diagrams below).

4.2 Wiring and connecting transducers to analog inputs
Note
Do not interconnect M- with MANA when wiring and connecting 2-wire transducers and
resistance transducers. An equalization current develops at the interconnection of M- with
MANA and corrupts the measured value. This also applies to unused inputs which are
programmed accordingly.
4.2.2
Wiring non-isolated transducers
Non-isolated transducer
Non-isolated transducers are interconnected with local ground potential. Always interconnect
MANA with local ground when using non-isolated transducers.
Local conditions or interference may cause potential differences CMV (static or dynamic)
between locally distributed measuring points. If the maximum CMV value is exceeded,
interconnect the measuring points by means of equipotential conductors.

Introduction
This chapter describes the wiring and connecting of resistance thermometers and resistors
and rules to be observed.
Supported resistance transducers
● With 4-wire connection
● With 3-wire connection
● With 2-wire connection
Wiring and connecting resistance thermometers and resistors
The module provides a constant current at terminals IC+ and IC- for current measurements.
The constant current is fed to the resistance for measuring its voltage potential. The constant
current cables must be wired directly to the resistance thermometer/resistor.
Measurements programmed for 4-or 3-wire connections compensate for line resistance and
return considerably higher precision compared to 2-wire connections.
Measurements with programmed 2-wire connections also record line impedance in addition
to their internal resistance.
4-wire connection of a resistance thermometer
The voltage generated at the resistance thermometer is measured across the M+ and Mterminals. Observe the correct polarity when wiring and connecting the devices (IC+ and M+,
and IC - and M- at the resistance thermometer).
Always wire and connect the IC+, M+, IC- and M- lines directly to the resistance
thermometer.

4.6 Wiring and connecting thermocouples
Thermocouple structure
Thermocouples consist of a pair of thermal probes and all necessary installation and
connecting parts. The thermocouple pair consists of two wires made of different metals, or of
metal alloys soldered or welded together at their ends.
The different thermocouple types, for example, K, J or N, are derived from different material
compositions. The measuring principle of all thermocouples is the same, irrespective of their
type.

Principles of analog value processing
4.6 Wiring and connecting thermocouples
Operating principle of thermocouples
Any temperature difference between the measuring point and the free ends of the
thermocouple (point of connection) generates a thermoelectric voltage. The thermoelectric
voltage is a function of the temperature difference between the measuring point and the free
ends, and is also determined by the material composition of the thermal elements.
As thermocouples always sense temperature differences, it is essential to maintain the free
ends at the known temperature of a reference junction in order to be able to determine the
temperature at the measuring point.
The thermocouples can be extended from their point of connection to the reference junction
by means of compensating lines. These compensating lines are made of the same materials
as the thermocouple wires. The supply lines from the reference junction to the module are
made of copper.
Note
Make sure of the correct polarity in order to avoid serious measuring errors.
Compensation for the reference junction temperature
You can compensate for the influence of temperature fluctuation at the reference junction by
means of a compensating circuit.
You have several options of measuring the reference junction temperature in order to obtain
an absolute temperature value as a function of the temperature difference between the
reference junction and the measuring point.
You can use either an internal or an external compensating circuit, depending on the
required location of the reference junction.

4.6.1
Wiring and connecting thermocouples with internal compensation
Function principle of internal compensation
Internal compensation allows you to form the reference point at the terminals of the analog
input module. In this case, route the compensating lines directly to the analog module. The
internal temperature sensor measures the module's temperature and returns a
compensation voltage.
Note that internal compensation is not as accurate as external compensation.
Wiring and connecting thermocouples with internal compensation
Wire the thermocouples either directly to the inputs of the module, or indirectly via
compensating lines. Each channel group can use any type of thermocouple supported by the
analog module, independently of other channel groups.

4.6.2
Wiring and connecting thermocouples with external compensation
Function principle of external compensation with compensating box
With external compensation, the temperature at the reference junction of the thermocouples
is evaluated using a compensating box.
The compensating box contains a bridge circuit which is calibrated to a defined reference
junction temperature /calibrating temperature.) The reference junction is formed by the
connecting ends of the thermocouple's equalizing conductor.
The resistance of the temperature-sensitive bridge changes as a function of the difference
between the actual reference temperature and calibrating temperature. This difference
induces a positive or negative compensating voltage, which is added to the thermoelectrical
voltage.
Wiring and connecting the compensating box
Terminate the compensating box at the COMP terminals of the module; the compensating
box must be installed at the reference junction of the thermocouples. The compensating box
be supplied with an electrically isolated voltage. The power supply module must provide
adequate noise filtering, for example, by means of grounded cable shielding.
The thermocouple terminals on the compensation box are not required, and should be shortcircuited (as an example, see the figure Wiring and connecting thermocouples with reference
junction (order no. M72166-xxx00).
Restrictions:
● The channel group parameters always apply to the all its channels (for example, input
voltage, integrating time etc.)
● For external compensation with wiring and connecting of the compensating box to the
module's COMP terminals, all thermocouples must be of the same type, and all channels
operating with external compensation must use the same type.

Wiring and connecting loads/actuators to analog outputs
The analog output modules can be used as current or voltage source for loads and
actuators.
Cables for analog signals
Always use shielded twisted-pair cables to wire analog signals. Form two twisted pairs of the
QV and S+, and M and S- signals in order to reduce interference. Connect both ends of the
analog cable shield to ground.
Any potential difference between the cable ends may cause an equipotential current on the
shield and disturbance on analog signals. Avoid this situation by grounding only one end of
the shielding.
Electrically isolated analog output modules
Electrically isolated analog output modules do not have a galvanic interconnection between
the reference point of measuring circuit MANA and the CPU's M terminal.
Always use electrically isolated analog input modules if there is any risk of potential
difference Viso developing between the reference point of measuring circuit MANA and the M
terminal of the CPU. Use an equipotential bonding conductor to interconnect the MANA
terminal and the M terminal of the CPU, in order to prevent Viso from exceeding the permitted
value.
Non-isolated analog output modules
When using on-isolated analog output modules, always interconnect the reference point
MANA of the of measuring circuit with terminal M of the CPU. Wire the MANA terminal to the M
terminal of the CPU. Any potential difference between MANA and the M terminal of the CPU
could otherwise corrupt the analog signal.

Wiring and connecting loads/actuators to voltage outputs
Wiring and connecting loads to a voltage output
The voltage outptus support the wiring and connecting of 2-wire and 4-wire loads. Certain
analog output modules, however, do not support both types of wiring and connecting.
Wiring 4-wire loads to the voltage output of an electrically isolated module
The 4-wire load circuit returns high precision. Wiring and connecting the S- and S+ sense
lines directly to the load. This allows direct measurement and correction of the load voltage.
Interference or voltage dips may lead to potential differences between the sense line S- and
the reference loop of analog circuit MANA. This potential difference may not exceed set limits.
Any potential difference above limits has a negative impact on analog signal precision.

Principles of analog modules
Introduction
This chapter describes the analog values for all measuring or output ranges supported by
the analog modules.
Analog value conversion
The CPU always processes the analog values in binary format.
Analog input modules convert the analog process signal to a digital format.
Analog output modules convert digital output values to analog signals.
Representation of analog values at a resolution of 16 bits
The digitized analog value applies to input and output values of the same rated range.
Analog values are output as fixed point numbers with two's complement. The resultant
assignment:

Principles of analog modules
Resolution < 16 bits
On analog modules with a resolution of < 16 bits, the analog value is stored left-aligned. The
unused least significant bit positions are padded with zeros ("0".)
Example
The example below demonstrates the zero padding of unused bit positions for low resolution
values.

Measured value resolution
The resolution of the analog values may differ, based on the analog module and module
parameters. At resolutions < 15 bits, all bits identified by "x" are set to "0".
Note
This resolution does not apply to temperature values. Converted temperature values are the
result of a conversion in the analog module.

Principles of analog modules
5.3 Setting the measuring method and ranges of analog input channels
5.3
Setting the measuring method and ranges of analog input channels
Two procedures
There are two methods of setting the measuring method and ranges of analog input
channels at analog modules:
● using a measuring range module and STEP 7
● hardwiring of the analog input channel and STEP 7
The method to use for the various analog modules is module-specific and is described in
detail in the special module chapters.
This section describes how to set up the type and range of measurement using measuring
range modules.
Setting the measurement type and ranges using measuring range modules
The analog modules are supplied with corresponding measuring range modules as required.
You may have to change the position of the measuring range module to suit the
measurement type and range.
Note
Note that the measuring range modules are installed on the side of the analog input module.
Always check whether the measuring range modules needs to be set up for a different
measurement type and range before you install the analog input module.
Optional settings of the measuring range modules
Optional settings of the measuring range modules: "A", "B", "C" and "D".
For detailed information on settings to be made for a specific measurement type and range,
refer to the special module chapter.
The settings for the different measurement types and ranges are also printed onto the
analog module.
Changing the positioning of measuring range modules
To insert the measuring range module into a different slot:
1. Remove the measuring range module from the slot of the analog input module by lifting it
out with a screwdriver.

2. Insert the measuring range module into the required slot (1) of the analog input module.
The indicator of the selected measuring range must be in line with the marker on the
module (2).
Figure 5-2
Inserting the measuring range module into the analog input module
Proceed likewise with any other measuring range modules.
You can now install the module.
CAUTION
Incorrect settings of the measuring range modules may lead to the destruction of the
module.
Always make sure that the measuring range module is in the correct position before you
connect a sensor to the module.

This chapter describes:
● the dependency of analog input and output values on CPU operating states and on the
supply voltage of the analog module
● the reaction of analog modules, based on the actual analog value within the relevant
range of values
● the influence of the operational limits of analog modules on analog IO values, as
illustrated by an example

5.4 Response of the analog modules
Influence of the supply voltage and operating state on the modules
The IO values of analog modules are determined by the CPU operating state and the
module's supply voltage.

Reaction to power failure
Power failure at analog modules is always indicated by their relevant SF LED. This
information is also available on the module (in diagnostics buffer data.)
Diagnostics interrupt triggering is based on parameter settings.

influence of errors on analog modules with diagnostics functions
Errors may lead to an entry in the diagnostics buffer and trigger a diagnostics interrupt at
analog modules with diagnostics function and corresponding parameter settings.
Influence of the range of values on the analog input module
The reaction of analog modules is determined by the actual input values within the range of

5.4 Response of the analog modules
5.4.3
Influence of operational limits and basic error limits
Operational limit
The operational limit represents the total measuring/output error of an analog module within
the permissible temperature range, based on the module's rating.
Basic error limit
The basic error limit represents the total measuring/output error at 25 °C, based on the
module's rating.
Note
The percentile values of operational and basic error limits in the module's technical data
always refer to the highest possible input and output value within the nominal range of the
module.
Example of the determination of the output error of a module
An analog output module SM 332; AO 4 x 12 Bit is being used for voltage output. An output
range of "0 to 10 V" is set. The module is operating at an ambient temperature of 30 °C,
i.e. the operational limit applies. The technical data of the module state:
● Operational limit for voltage output: ±0,5 %
Hence, an output error of ±0.05 V (±0.5 % of 10 V) across the nominal range of the module
must be expected.
At an actual voltage of 1 V, for example, the module will then output a value in the range
from 0.95 V to 1.05 V. The relative error is ±5 % in this case.
For the example, the figure below shows how the relative error decreases as the output
value approaches the end of the 10-V range.

5.5 Conversion and cycle times of analog modules
5.5
Conversion and cycle times of analog modules
Conversion time of analog input channels
The conversion time is the total of the basic conversion time plus additional processing times
of the module for:
● Resistance measurement
● Wirebreak monitoring
The basic conversion time depends directly on the conversion method of the analog input
channel (integrating method, actual value conversion.)
The integration time of integrating conversions has a direct influence on conversion times.
The integration time depends on the interference frequency suppression you set in STEP 7.
For information on basic conversion times and additional processing times of the various
analog modules, refer to the technical data of the relevant module.
Cycle time of analog input channels
Analog-to-digital conversion, and the transfer of digitized measured values to memory and/or
to the backplane bus, are carried out sequentially, i.e. the analog input channels are
converted in successive order. The cycle time, i.e. the time expiring until an analog input
value is converted again, represents the accumulated conversion time of all activated analog
input channels of the analog input module.
The figure below provides an overview of the cycle time elements for an n-channel analog
module.

5.5 Conversion and cycle times of analog modules
Example
Two analog input channels of the SM 331; AI 2 x 12 Bit analog input module form a channel
group. You must therefore grade the cycle time in steps of 2.
Setting smoothing of analog values
Certain analog input modules allow you to set smoothing of analog values in STEP 7.
Using smoothing
Smoothed analog values provide a reliable analog signal for further processing.
It is useful to smooth the analog values with slow variations of measured values, for
example, when measuring temperature.
Smoothing principle
The measured values are smoothed by digital filtering. Smoothing is accomplished by the
module calculating mean values, derived from a defined number of converted (digitized)
analog values.
The user configures up to four grades of smoothing (none, low, average, high). The grade
determines the number of analog signals used for averaging.
A higher smoothing provides a more reliable analog value, and prolongs the time it takes to
apply a smoothed analog signal following a step response (see the example below.)

Further information on smoothing
For information showing whether a specific module supports smoothing functions, and
special features to observe, refer to the chapter dealing with the analog input module.
Conversion time of the analog output channels
The conversion time of the analog output channels includes the transfer of digitized output
values from internal memory, and their digital-to-analog conversion.
Cycle time of analog output channels
Analog output channels are converted sequentially, i.e. successively.
The cycle time, i.e. the time expiring until an analog output value is converted again, is
equivalent to the accumulated conversion times of all activated analog output channels.
Refer to the figure Cycle time of an analog IO channel.
Tip
You should disable all unused analog channels in STEP 7 in order to reduce cycle times.

5.6 Settling and response times of analog output channels
5.6
Settling and response times of analog output channels
Settling time
The settling time (t2 to t3), i.e. the time expiring until a converted value has gained a specified
level at an analog output, is load-dependent. We therefore distinguish between resistive,
capacitive and inductive load.
For information on settling times as a function of load at the various analog output modules,
refer to the technical data of the relevant module.
Response time
The worst case response time (t1 to t3), i.e. the time expiring between the input of digital
output values to internal memory, and the signal settling time at the analog output, may be
equivalent to the total of cycle time plus settling time.
The worst case scenario is given, when the analog channel has been converted immediately
before a new output value is transferred, and is not converted again until all other channels
have been converted (cycle time.)

Programming analog modules
Introduction
The properties of analog modules may differ. The module properties can be programmed.
Programming tools
You program analog modules in STEP 7. Always program the module while the CPU is in
STOP mode.
After you defined all parameters, download these from your PG to the CPU. The CPU
transfers the parameters to the relevant analog modules at the STOP → RUN transition.
Also, position the measuring range modules of the module as required.
Static and dynamic parameters
Parameters are organized by static and dynamic properties.
Set the static parameters while the CPU is in STOP, as described earlier.
You can also modify dynamic parameters in the active user program using SFCs. However,
the parameters set in STEP 7 will be applied again after a RUN → STOP, STOP → RUN
transition of the CPU.

Parameters of analog input modules
For information on parameters supported by specific analog modules, refer to the chapter
dealing with the relevant module.
The defaults apply if you have not set any parameters in STEP 7.
5.8
Diagnostics of analog modules
Programmable and non-programmable diagnostic messages
We distinguish between programmable and non-programmable diagnostic messages.
You only obtain programmable diagnostic messages if you have enabled diagnostics at the
relevant parameters. Program these functions in the "Diagnostics" parameter block in STEP
7.
The the analog module always provides non-programmable diagnostic messages,
irrespective of the enable state of diagnostic functions.
Reactions to a diagnostic message in STEP 7
Actions initiated by diagnostic messages:
● The diagnostic message is written to the diagnostics buffer of the analog module, and is
then passed to the CPU.
● The error LED on the analog module is lit.
● When "Enable Diagnostics Interrupt" is set in STEP 7, the system triggers a diagnostic
interrupt and calls OB82.
Reading diagnostic messages
You can read detailed diagnostic messages in the user program using SFCs.
Viewing the cause of error
You can view the cause of the error in the module diagnostics data in STEP 7 (refer to the
STEP 7 Online Help.)
Diagnostic message included in the measured value of analog input modules
All analog input modules return the measured value 7FFFH as a reaction to errors,
irrespective of parameter settings. This measured value indicates either overflow, error, or a
disabled channel.

5.9 Interrupts of analog modules
5.9
Interrupts of analog modules
Introduction
This section describes the interrupt response of analog modules. Always distinguish
between the following interrupts:
● Diagnostic interrupt
● Hardware interrupt
Note that certain analog modules do not support interrupts, or are only partially capable of
"handling" the interrupts described below. For information on modules which support
interrupt functionality, refer to their technical data.
Description of the STEP 7 blocks
For detailed information on the OBs and SFCs mentioned below, refer to the STEP 7 Online
Help.
Enabling interrupts
There are no default interrupt settings, that is, interrupts are disabled if not set accordingly.
Program the interrupt enable parameter in STEP 7.
Diagnostic interrupt
Incoming error events (initial occurrence) and outgoing error events (error is cleared) are
reported by means of diagnostic interrupt, if this interrupt is enabled.
The CPU interrupts user program execution in order to process diagnostic interrupt OB82.
You can call SFC51 or 59 in OB82 in the user program to view details of diagnostics data
output by the module.
Diagnostics data remain consistent until the program exits OB82. The program
acknowledges the diagnostic interrupt at the module when it exits OB82.

Principles of analog modules
5.9 Interrupts of analog modules
Hardware interrupt with "high or low limit exceeded" trigger
Define a working range by setting a high and low limit. If the process signal (for example, the
temperature) overshoots this working range, the module triggers a hardware interrupt,
provided the interrupt is enabled.
The CPU interrupts user program execution in order to execute hardware interrupt OB40.
In the user program of OB 40, you can define the reaction of the automation system to the
violation of limits.
The program acknowledges the diagnostic interrupt at the module when it exits OB40.
Note
Note: the system does not generate a hardware interrupt if your limit setting exceeds the
overshoot or undershoot range.
Structure of the start information variable OB40_POINT_ADDR of OB 40
The channel at which a specific limit is exceeded is logged to the OB40_POINT_ADDR
variable in the start information of OB40. The diagram below shows the bit assignment of
DWORD 8 in local data.

Start information of OB40: which limits event has triggered a hardware interrupt
Hardware interrupt triggered by "End of cycle reached"
You can synchronize a process with the cycle of the analog input module by programming a
hardware interrupt trigger at the end of the cycle.
One cycle comprises the conversion of the measured values of all active channels of the
analog input module. The module processes the channels in successive order. After all
measured values were successfully converted, the module outputs an interrupt to the CPU in
order to report new measured values at its channels.
You can always use this interrupt to download the actual converted analog values.

Diagnostics
For information on diagnostic messages at the "group diagnostics" parameter, refer to the
table Diagnostic messages of analog input modules.
Hardware interrupts
Hardware interrupts for channel groups 0 and 1 can be programmed in STEP 7. However,
set a hardware interrupt only for the first channel of a channel group, that is, either at
channel 0, or at channel 2

Analog modules
6.3 Analog input module SM 331; AI 8 x 16 bit; (6ES7331-7NF00-0AB0)
High-speed update of measured values
A high-speed update of measured values at two channels of a channel group is three times
compared to the activation of several channel groups.
Example: When channels 0 and 1 are active with 2.5 ms filtering, both channels return new
measured values to the PLC at intervals of 10 ms. (with other settings, the refresh rate is
equivalent to the filter setting.)
High-speed update of measured values is only possible if both channels of channel group 0
and 1 are active, that is, the "measuring type" parameter is set. However, only one of the two
channel groups 0 or 1 may be active (not concurrently active.)

Wiring: Voltage and current measurement
Wire the voltage inputs of the channel voltage in parallel using the corresponding shunt
resistor when measuring current. Bridge the channel input terminals with the adjacent
connector terminals.
Example: You configure channel 0 for current measurement by bridging terminals 22 and 2,
and terminals 23 to 3.
At the channel configured for current measurements, connect the shunt resistor to the
adjacent channel terminals in order to achieve the specified precision.

Parameter reassignment in RUN
If you reassign parameters in RUN, the following special characteristic applies.
SF LED is lit:
If a diagnostics was pending prior to reconfiguration, the SF LEDs (on CPU, IM or module)
may be lit even though diagnostics are no longer pending and the module is operating
correctly.
Solution:
● Only assign new parameters if no diagnostics is pending, or
● unplug module and plug it in again.

Measurement types and ranges
Introduction
The measurement type and range is configured at the "measuring range" parameter in
STEP 7.
The default setting of the module is "voltage" measurement with "± 10V" range. You can use
these default settings without having to program the SM 331; AI 8 x 16 Bit in STEP 7.

Channel groups
The channels of SM 331; AI 8 x 16 Bit are arranged in four groups of two channels. You can
assign parameters only to one channel group.
The table below shows the relevant configuration of channel groups. The channel group
number is required to program SFC parameters in the user program.

Additional information on SM 331; AI 8 x 16 Bit
Unused channels
Set the "disabled" value at the "measuring type" parameter for unused channels. This setting
reduces module cycle times.
As certain programmed inputs may remain unused due to the channel group configuration,
make allowances for the special features of those inputs outlined below in order to be able to
use the diagnostic functions at these used channels:
● Measuring range 1 V to 5 V: wire the used input and unused input of the same channel
group in parallel.
● Current measurement, 4 mA to 20 mA: wire the used input and unused input of the same
channel group in series. Connect a shunt resistor to each programmed and unused
channel.
● Other measuring ranges:Short-circuit the plus and minus inputs of the channel.
Line continuity check
The line continuity check is available for the 1 V to 5 V and 4 mA to 20 mA ranges.
Rule for both measuring ranges:
When the line continuity check is enabled, the module logs the wire-break to diagnostics
data when the current drops below 3.6 mA (0.9 V.)
The module also triggers a diagnostic interrupt if this function is enabled in the program.
A wire break can only be signaled by means of the lit SF LED and the diagnostic bytes must
be evaluated in the user program if diagnostic interrupts are disabled.
When line continuity check is disabled and diagnostic interrupts are enabled, the module
triggers a diagnostic interrupt when underflow is detected.

Special features in programming high and low limits
The programmable limits (hardware interrupt triggers) of SM 331; AI 8 x 16 Bit differ from the
range of value shown in the Overview of parameters of SM 331; AI 8 x 16 Bit. table.
Reason: The calculation methods deployed in the module software to evaluate the process
variables do not allow the reporting of values up to 32511 in certain situations. The process
value triggering a hardware interrupt at underflow or overflow limits is based on the
calibration factors of the relevant channel, and may vary between the low limits shown in the
table below and the value 32511 (7EFFH).
You may not define any limits which exceed the minimum limits specified in the table below.

Measuring errors as a result of CMV
SM 331; AI 8 x 16 Bit is capable of taking measurements, irrespective of the presence of any
CMV in the AC or DC range.
With AC CMV values of a multiple of filter frequency settings, noise is suppressed as a result
of ADC integration time and common mode suppression at the input amplifiers. With AC
CMV < 35 VRMS, the noise suppression of > 100 dB results in negligible measurement errors.
The influence of DC CMV can only be reduced to minimum using the noise suppression
function of the input amplifier unit. A certain degradation of measuring accuracy in proportion
to CMV must be expected. The worst case error is generated at 50 VDC between one
channel and the remaining seven channels. The calculated worst case error is 0.7% at 0 °C
to 60 °C, while the measured error usually lies at ≤ 0.1% at 25 °C.

Reassigning parameters in RUN
If you reassign parameters in RUN, the following special characteristic applies.
SF LED is lit:
If a diagnostics was pending prior to reconfiguration, the SF LEDs (on CPU, IM or module)
may be lit even though diagnostics is no longer pending and the module is operating
correctly.
Solution:
● Only assign new parameters if no diagnostics is pending, or
● unplug module and plug it in again.

Modes of operation
Operating modes of SM 331; AI 8 x 16 Bit:
● 8-channel mode
● 4-channel mode
8-channel operating mode
In this mode, the module changes between the two channels of each group. The four ADCs
of the module simultaneously convert channels 0, 2, 4 and 6. The ADCs first convert the
channels with even numbers, and then the channels with the odd numbers 1, 3, 5 and 7 (see
the figure below.)

Analog modules
6.4 Analog input module SM 331; AI 8 x 16 Bit; (6ES7331-7NF10-0AB0)
Cycle time of module in 8-channel mode
The channel conversion time is based on the programmed noise suppression. The channel
conversion time is 76 ms, including communication time, at a set interference frequency of
50 Hz. The channel conversion time is 65 ms when you set an interference frequency of 60
Hz. You can reduce channel conversion times to 16 ms by setting an interference frequency
of 400 Hz. When you set 50, 60 and 400 Hz , the channel conversion time amounts to 88
ms. The module then has to switch to a different channel of the group by means of the OptoMOS relay. Opto-MOS relays require 7 ms for switching and settling. The table below shows
this correlation.

4-channel operating mode
In this mode, the module does not change between the channels of the groups. The four
ADCs of the module simultaneously convert the channels 0, 2, 4 and 6.

4-channel mode cycle time
Module cycle time
The converted value settles to 100% within 80 ms and is updated every 10 ms when
4-channel mode is set. The channel and module cycle times are always identical, because
the module does not change between the channels of a group: 10 ms.
Channel conversion time = channel cycle time = module cycle time = 10 ms

Analog modules
6.4 Analog input module SM 331; AI 8 x 16 Bit; (6ES7331-7NF10-0AB0)
Unused channels
Set the "disabled" value at the "measuring method" parameter for unused channels. This
setting reduces module cycle times.
As certain programmed inputs may remain unused due to the channel group configuration in
8-channel mode, make allowances for the special features of these inputs outlined below to
activate the diagnostics functions at the channels being used:
● Measuring range 1 V to 5 V: wire the used input and unused input of the same channel
group in parallel.
● Current measurement, 4 mA to 20 mA: wire the used input and unused input of the same
channel group in series. A shunt resistor must be connected for each programmed and
unused channel.
● Other measuring ranges: Short-circuit the plus and minus inputs of the channel.
Line continuity check
The line continuity check is available for the voltage measuring ranges and for the 4 mA to
20 mA current measuring range.
If you configured a measuring range of ± 5V, 1 V to 5 V, ± 10 V, 4 mA to 20 mA, and
enabled the line continuity check, the analog input module logs a wire-break event in
diagnostics data when the underflow (32768) is reached.
The module also triggers a diagnostic interrupt if this function is enabled in the program.
A wire break can only be signaled by means of the lit SF LED and the diagnostic bytes must
be evaluated in the user program if diagnostic interrupts are disabled.
Under the following circumstances, wire-break detection can take up to 2 s:
● If a wire break occurs during voltage measurement.
● If a wire break occurs on the front-connector jumpers from shunt (250 Ω) to the inputs
during current measurement.
In this period, the measured value can run through the entire valid value range.
If you configured a measuring range of 4 mA to 20 mA, disabled the line continuity check,
and enabled diagnostic interrupts, the module triggers a diagnostic interrupt when the
underflow value is reached.
Overflow, underflow and hardware interrupt limits
The limits in diagnostics response to overflow and underflow in certain measuring ranges
differ compared to the listed ranges starting at the chapterAnalog value representation for
analog input channels of the manual. In certain situations the numerical methods of the
module software used to evaluate the process variables do not return values up to 32511.
Do not set any hardware interrupt limits higher than the lowest possible overflow or
underflow response limits. End of cycle interrupt starting at the chapter Analog value
representation for analog input channels.

of cycle interrupt. The interrupt is set when enabled channels have been converted.

Measurement types and measuring ranges
Introduction
The analog input module has measuring range modules. The measurement type and range
is configured at the "measuring range" parameter in STEP 7.
The default setting of the module STEP 7 is "voltage" measurement with "± 10V" range. You
can use those default settings without having to program the SM 331;
AI 8 x 14 Bit High Speed in STEP 7.
Measuring range modules
You may have to change the position of the measuring range module to suit the
measurement type and range. See table Setting measuring methods and ranges of analog
input channels. The settings are also printed on the module. Mark the position of the
measuring range module on the front door (see figure).

Isochronous mode
Properties
Reproducible reaction times (i.e. of the same length) are achieved in a SIMATIC system by
means of a constant DP bus cycle, and synchronization of the single cyclic processes
outlined below:
● Independent user program cycle. The length of the cycle time may vary due to non-cyclic
program branching.
● Independent and variable DP cycle on the PROFIBUS subnet
● Cyclic operation of the backplane bus of the DP slave.
● Cyclic signal preparation and conversion at the electronic modules of the DP slave.
The constant DP cycle runs in synchronism and at the same length. The CPU run levels
(OB61 to OB64) and isochronous IO are synchronized with this cycle. I/O data are therefore
transferred at defined and constant intervals (isochronous mode.)
Requirements
● The DP master and slave must support isochronous mode. You require STEP 7 V5.2 or
higher.
Mode of operation: Isochronous mode
Table 6- 16
Conditions of isochronous mode:
Standard Mode
Filtering and processing time TWE between reading actual values and writing these to the
transfer buffer(the value defined for TWE applies, irrespective of the enable status of diagnostics)
max. 625 μs
including an input delay time of
10 µs
TDPmin
3.5 ms
Diagnostics interrupt
max. 4 x TDP
Fast Mode (only possible with 6ES7331-7HF01-0AB0)
Filter and processing time TWE between reading actual value and writing the results to the
transfer buffer (diagnosis not selectable)
max. 625 μs
including an input delay time of
10 µs
TDPmin
1 ms
Note
You can accelerate the cycle of your DP system by setting "Fast Mode." However, this is at
the expense of diagnostics: Diagnostics functions will be disabled in this operating mode.

Analog modules
6.5 Analog input module SM 331; AI 8 x 14 Bit High Speed; isochrone; (6ES7331-7HF0x-0AB0)
The minimum Ti value of 875 µs which you can set in HW Config is derived from the defined
TWE value plus calculation and transfer times required by the IM 153.
The specified TDPmin value is determined by the size of the DP slave/IM 153 configuration: Of
the diverse installed modules, the slowest always determines the time TDPmin.
Note
When operated in "isochronous" mode, the modules automatically sets "Integration time:
none/interference frequency", irrespective of parameter settings in STEP 7. none /
interference frequency". "Process interrupt" functionality is not available in "isochronous"
mode.
Calculation of filter and processing times
The same time conditions always apply, regardless of the number of configured channels.
The time relative to the clock signal for reading a specific channel is calculated according to
the formula:
TWE_CH = (channel number +1) x 52 µs + tv; tv = 119 to 209 µs

Calculation of filter and processing times
Definition of isochronous mode
The module starts with the analog-to-digital conversion of channel 7, and saves the result
internally. Next, it converts channels 6...0 sequentially at intervals of 52 ms and in the same
way. After an additional internal processing time, it outputs the result of all converted
channels to the backplane bus interface where it can be fetched by the CPU.
Further information
For further information on isochronous mode, refer to the STEP 7 Online Help, in the
operating instructions ET 200M Distributed IO System
(http://support.automation.siemens.com/WW/view/en/1142798) and in the Synchronicity

As certain programmed inputs may remain unused due to the channel group configuration,
make allowances for the special features of these inputs outlined below in order to be able to
use the diagnostics functions at these used channels:
● Measuring range 1 V to 5 V: wire the used input and unused input of the same channel
group in parallel.
● Current measurement, 2-wire transducer: There are two options of wiring the channel
circuit.
a) Open unused inputs; channel group diagnostics disabled. If you were to enable
diagnostics, the analog module would trigger a single diagnostic interrupt, and light up its
SF LED.
b) Loading the unused input using a 1.5 kΩ to 3.3 kΩ resistor. This allows you to enable
diagnostics for this channel group.
● Current measurement 4 mA to 20 mA, 4-wire transducer: wire the used input and unused
input of the same channel group in series.
Line continuity check for the 4 mA to 20 mA measuring range
If you configured a measuring range of 4 mA to 20 mA, and enabled the line continuity
check, the analog input module logs a wire-break event to diagnostics data when the current
drops below 1.185 mA.
The module also triggers a diagnostics interrupt if this function is enabled in the program.
A wire break can only be signaled by means of the lit SF LED and the diagnostic bytes must
be evaluated in the user program if diagnostics interrupts are disabled.
If you configured a measuring range of 4 mA to 20 mA, disabled the line continuity check,
and enabled diagnostic interrupts, the module triggers a diagnostic interrupt when the
underflow value is reached.

Using PTC resistors
PTCs are suitable for monitoring the temperature of or providing thermal protection for
complex drives and transformer windings. The module has no analog values when PTC
resistances are used. Status information on fixed temperature ranges are displyed instead of
analog values.
● When setting the parameters, select measurement type R "Resistance" and measuring
range "PTC".
● Connect the PTC (see "Terminal diagram for resistance measurement").
● Use PTC resistors that comply with IEC 60034-11-2 (previously, PTC thermistors that
complied with DIN/VDE 0660, Part 302).

● Notes on programming
Note
Only bits 0 and 2 in the process image input are relevant for evaluation. You can use bits
0 and 2 to monitor the temperature of a motor, for example.
Bits 0 and 2 in the process image input cannot be saved. When assigning parameters,
make sure that the motor, for example, starts up in a controlled manner (by means of an
acknowledgment).
Bits 0 and 2 can never be set at the same time; they are set one after the other.
Using silicon temperature sensors
Silicon temperature sensors are commonly used to detect temperatures in motors.
● When assigning the parameters, select measurement type "thermoresistor" and
measuring range "KTY83/110" or "KTY84/130".
● Connect the temperature sensor (see "Terminal diagram for resistance measurement").
Use temperature sensors which comply with the Product Specifications published by
Philips Semiconductors.
● KTY83 series (KTY83/110)

Properties
● 8 inputs in 4 channel groups
● Programmable measurement type at each channel group
– Voltage
– Current
– Resistance
– Temperature
● Programmable resolution at each channel group (9/12/14 bits + sign)
● Any measuring range selection per channel group
● Programmable diagnostics and diagnostic interrupt
● Programmable limit value monitoring for 2 channels
● Programmable hardware interrupt when limit is exceeded
● Electrically isolated to CPU and load voltage (not for 2-wire transducers)
Resolution
The measured value resolution is directly proportional to the selected integration time, that
is, the measured value resolution increases in proportion to length of the integration time at
the analog input channel.
Diagnostics
For information on diagnostics messages at the "group diagnostics" parameter, refer to
chapter Diagnostic messages of analog input modules.
Hardware interrupts
Hardware interrupts for channel groups 0 and 1 can be programmed in STEP 7. However,
set a hardware interrupt only for the first channel of a channel group, that is, either at
channel 0, or at channel 2

Measurement types and ranges
Introduction
Module SM 331; AI 8 x 12 Bit has measuring range modules
The measurement type and range is configured at the "measuring range" parameter in
STEP 7.
The default setting of the module is "voltage" measurement with "± 10V" range. You can use
these default settings without having to program the SM 331; AI 8 x 12 Bit in STEP 7.
Measuring range modules
You may have to change the position of the measuring range modules to suit the
measurement type and range (see the chapter Setting the measuring types and ranges of
analog input channels). The necessary settings are also available on the module's imprint.
Mark the position of the measuring range module on the front door (see figure).

Additional information on SM 331; AI 8 x 12 Bit
Unused channels
As certain programmed inputs may remain unused due to the channel group configuration,
make allowances for the special features of these inputs outlined below in order to be able to
use the diagnostics functions at these used channels:
● Voltage measurement (except 1 V to 5V) and for thermocouples: Short-circuit unused
channels and connect these with MANA. This optimizes interference immunity of the
analog input module. Set the "disabled" value at the "measurement type" parameter for
unused channels. This setting reduces module cycle times. Also short-circuit the COMP
input if this is not used.
● Measuring range 1 V to 5 V: wire the used and unused inputs of the same channel group
in parallel.
● Current measurement, 2-wire transducer: There are two options of wiring the channel
circuit.
a) Open unused input; channel group diagnostics disabled. If you were to enable
diagnostics, the analog module would trigger a single diagnostic interrupt, and light up its
SF LED.
b) Loading the unused input using a 1.5 kΩ to 3.3 kΩ resistor. This allows you to enable
diagnostics for this channel group.
● Current measurement 4 mA to 20 mA, 4-wire transducer: wire the unused inputs of the
same channel group in series.
All channels deactivated
If you disable all input channels of the module and enable diagnostics at the parameters of
SM 331; AI 8 x 12 Bit, the module does not report "external auxiliary voltage missing."
Line continuity check for the 4 mA to 20 mA measuring range
If you configured a measuring range of 4 mA to 20 mA, and enabled the line continuity
check, the analog input module logs a wire-break event to diagnostics data when the current
drops below 3.6 mA.
The module also triggers a diagnostics interrupt if this function is enabled in the program.
A wire break can only be signaled by means of the lit SF LED and the diagnostic bytes must
be evaluated in the user program if diagnostics interrupts are disabled.
If you configured a measuring range of 4 mA to 20 mA, disabled the line continuity check,
and enabled diagnostic interrupts, the module triggers a diagnostic interrupt when the
underflow value is reached.
Line continuity check
The line continuity check is designed only for temperature measurements (thermocouples
and thermoresistors.)

● Two inputs in one channel group
● Programmable measurement type for each channel group
– Voltage
– Current
– Resistance
– Temperature
● Programmable resolution at each channel group (9/12/14 bits + sign)
● Any measuring range selection per channel group
● Programmable diagnostics and diagnostic interrupt
● Programmable limit value monitoring for one channel
● Programmable hardware interrupt when limit is exceeded
● Electrically isolated from the CPU and load voltage (not for 2DMU)
Resolution
The measured value resolution is directly proportional to the selected integration time, that
is, the measured value resolution increases in proportion to length of the integration time at
the analog input channel.

Measurement types and measuring ranges
Introduction
SM 331; AI 2 x 12 Bit is equipped with a measuring range module. The measurement type
and range is configured at the "measuring range" parameter in STEP 7. You can use the
default "voltage" measurement type and "± 10 V range without having to program the
SM 331; AI 2 x 12 Bit in STEP 7.
Measuring range module
Change the position of the measuring range module to set the measurement type and range
(see the chapter Setting the measurement types and ranges of analog input channels ). The
necessary settings are also available on the module's imprint. Mark the position of the
measuring range module on the front door (see figure).

Channel groups
The two channels of SM 331; AI 2 x 12 Bit form a channel group. You can assign parameters
only to one channel group.
SM 331; AI 2 x 12 Bit is equipped with a measuring range module for channel group 0.
Line continuity check
The line continuity check is designed only for temperature measurements (thermocouples
and thermoresistors.)
Special features of the line continuity check for the 4 mA to 20 mA measuring range
If you configured a measuring range of 4 mA to 20 mA, and enabled the line continuity
check, the analog input module logs a wire-break event to diagnostics data when the current
drops below 3.6 mA.
The module also triggers a diagnostics interrupt if this function is enabled in the program.
A wire break can only be signaled by means of the lit SF LED and the diagnostic bytes must
be evaluated in the user program if diagnostics interrupts are disabled.
If you configured a measuring range of 4 mA to 20 mA, disabled the line continuity check,
and enabled diagnostic interrupts, the module triggers a diagnostic interrupt when the
underflow value is reached.

Additional information on SM 331; AI 2 x 12 Bit
Unused channels
Short-circuit unused channels and connect these with MANA. This optimizes interference
immunity of the analog input module. Set the "disabled" value at the "measurement type"
parameter for unused channels. This setting reduces module cycle times.
Also short-circuit the COMP input if this is not used.
As certain programmed inputs may remain unused due to the channel group configuration,
make allowances for the special features of these inputs outlined below in order to be able to
use the diagnostics functions at these used channels:
● Measuring range 1 V to 5 V: wire the used input and unused input of the same channel
group in parallel.
● Current measurement, 2-wire transducer: There are two options of setting up the channel
circuit:
a) Open unused input; channel group diagnostics disabled. The analog module would
trigger a single diagnostics interrupt and set its SF LED if diagnostics is enabled.
b) Terminating the unused input using a 1.5 kΩ to 3.3 kΩ resistor. This allows you to
enable diagnostics for this channel group.
● Current measurement 4 mA to 20 mA, 4-wire transducer: wire the used input and unused
input of the same channel group in series.
Line continuity check
The line continuity check is designed only for temperature measurements (thermocouples
and thermoresistors.)
Special features of the line continuity check for the 4 mA to 20 mA measuring range
If you configured a measuring range of 4 mA to 20 mA, and enabled the line continuity
check, the analog input module logs a wire-break event to diagnostics data when the current
drops below 3.6 mA.
The module also triggers a diagnostics interrupt if this function is enabled in the program.
A wire break can only be signaled by means of the lit SF LED and the diagnostic bytes must
be evaluated in the user program if diagnostics interrupts are disabled.
If you configured a measuring range of 4 mA to 20 mA, disabled the line continuity check
and enabled diagnostic interrupts, the module triggers a diagnostic interrupt when the
underflow value is reached.

Modes of operation
Operating modes of SM 331; AI 8 x RTD:
● 8-channel mode (hardware filter)
● 8-channel mode (software filter)
● 4-channel mode (hardware filter)
The operating mode influences the module cycle time.
8-channel mode (hardware filter)
In this mode, the module changes between the two channels of each group. The four ADCs
of the module simultaneously convert channels 0, 2, 4 and 6. The ADCs first convert the
channels with even numbers, and then the channels with the odd numbers 1, 3, 5 and 7 (see
the figure below.)

Cycle time of module in 8-channel mode
The channel conversion time, including module communication time, is 84 ms. The module
must change to the second channel of the group using OptoMOS relays when conversion is
completed. Opto-MOS relays require 12 ms for switching and settling. Each channel requires
a time of 97 ms, i.e. the total cycle time equals 194 ms.
Cycle time = (tK + tU) x 2
Cycle time = (84 ms + 16 ms) x 2
Cycle time = 200 ms
tC: Conversion time for one channel
tC: Channel changeover time within the channel group
8-channel mode (software filter)
Analog-to-digital conversion in this mode is identical to the conversion in 8-channel mode
(hardware filter). The four ADCs of the module simultaneously convert channels 0, 2, 4 and
6. The ADCs first convert the channels with even numbers, and then the channels with the
odd numbers 1, 3, 5 and 7 (see the figure below.)

Analog modules
6.9 Analog input module SM 331; AI 8 x RTD; (6ES7331-7PF01-0AB0)
Cycle time of module in 8-channel mode (software filter)
The channel conversion time is based on the programmed interference frequency. The
channel conversion time is 32 ms, including communication time, when you set an
interference frequency of 50 Hz. The channel conversion time is 27 ms when you set an
interference frequency of 60 Hz. You can reduce channel conversion times to 9 ms by
setting an interference frequency of 400 Hz. As in "hardware filter, 8channel" mode, the
module has to toggle to the second channel of the group within a changeover time of 16 ms
using the Opto-MOS relays. The table below shows this correlation.

Cycle time of the module in 4-channel mode (hardware filter)
The converted value settles to 100% within 80 ms and is updated at intervals of 10 ms when
4-channel mode is set. The channel and module cycle times are always identical, as the
module does not change between the channels of a group: 10 ms.
Channel conversion time = channel cycle time = module cycle time = 10 ms

6.9 Analog input module SM 331; AI 8 x RTD; (6ES7331-7PF01-0AB0)
Cycle time extension due to wire-break monitoring
The wire-break monitoring software function of the module is available in all operating
modes.
The cycle time of the module is doubled in 8-channel mode (hardware or software filter),
irrespective of the number of channels at which wire-break monitoring is enabled.
In 4-channel mode (hardware filter), the module interrupts processing of input data for the
duration of 100 ms and performs a line continuity check. That is, each line continuity check
extends the module cycle time by 100 ms.
Unused channels
In order to avoid incorrect measurements, an unused channel from an active group of
channels must be configured. Connect a resistor of the nominal range to the unused channel
in order to suppress diagnostics errors.
Set the "disabled" value at the "measurement type" parameter for unused channels. This
setting reduces module cycle times.
Short-circuit to M or L
The module does not suffer any damage if you short-circuit an input channel to M or L.. The
channel continues to output valid data and does not report a diagnostics event.
End of cycle interrupt
You can synchronize a process with the conversion cycle of the module by enabling the end
of cycle interrupt. The interrupt is set when all active channels have been converted.

process or end of cycle interrupts.

** Wire-break monitoring in 4-channel mode (hardware filter) at intervals of three seconds.
** In 8-channel software mode (software filter), series-mode rejection is reduced as follows:
•
50 Hz > 70 dB
•
60 Hz > 70 dB
• 400 Hz > 80 dB
*** The operational limit comprises only the basic error of the analog input at Ta = 25 °C and the total temperature error.
The total error must include the compensation error of the cold reference junction. Internal compensation of the reference
junction = max. 1.5 °C
External compensation of the reference junction = precision of external RTD employed ± 0.1 °C.
External compensation of the reference junction which maintains the reference junction at 0 °C or 50 °C = precision of
temperature control for the reference junction.
**** With thermocouple type B, a missing compensation of the reference junction temperature has no significant effect
owing to its slight increase from approx. 0 °C to 40 °C. With missing compensation and set measuring type "Compensation
to 0 °C", the deviation with thermocouple type B at measuring temperatures between:
•
700 °C and 1820 °C is < 0.5 °C
• 500 °C and 700 °C is < 0.7 °C.
If the reference junction temperature is approximately that of the module temperature, "internal compensation" should be
set. As a result, the error for the temperature range from 500 °C to 1820 °C is reduced to < 0.5 °C.
***** In 4-channel mode, the converted value settles to 100 % within 80 ms. The value determined in this process is set at
intervals of 3.3 ms (max. 10 ms).
****** If internal or external reference junction compensation is configured, the measured values of all channels are not
updated for about 1 s in each minute. ###

Modes of operation
Operating modes of SM 331; AI 8 x TC:
● 8-channel mode (hardware filter)
● 8-channel mode (software filter)
● 4-channel mode (hardware filter)
The operating mode influences the module cycle time.
8-channel mode (hardware filter)
In this mode, the module changes between the two channels of each group. The four ADCs
of the module simultaneously convert channels 0, 2, 4 and 6. The ADCs first convert the
channels with even numbers, and then the channels with the odd numbers 1, 3, 5 and 7 (see
the figure below.)

Cycle time of the module in 8-channel mode (hardware filter)
The channel conversion time, including module communication time, is 91 ms. The module
must change to the second channel of the group using OptoMOS relays when conversion is
completed. Opto-MOS relays require 7 ms for switching and settling. Each channel requires
a time of 98 ms, i.e. the total cycle time equals 196 ms.
Cycle time = (tK + tU) x 2
Cycle time = (91 ms + 7 ms) x 2
Cycle time = 196 ms
tC: Conversion time for one channel
tC: Time for changing over to the other channel in a channel group
8-channel mode (software filter)
Analog-to-digital conversion in this mode is similar to conversion in 8-channel mode
(hardware filter). The four ADCs of the module simultaneously convert channels 0, 2, 4 and
6. The ADCs first convert the channels with even numbers, and then the channels with the
odd numbers 1, 3, 5 and 7 (see the figure below.)

6.10 Analog input module SM 331; AI 8 x TC; (6ES7331-7PF11-0AB0)
Cycle time of module in 8-channel mode (software filter)
However, the channel conversion time is oriented on the programmed noise suppression.
The channel conversion time is 76 ms, including communication time, when you set an
interference frequency of 50 Hz. The channel conversion time is 65 ms when you set an
interference frequency of 60 Hz. You can reduce channel conversion times to 16 ms by
setting an interference frequency of 400 Hz. As in "hardware filter, 8channel" mode, the
module has to change to the second channel of the group within a changeover time of 7 ms
using the Opto-MOS relays. The table below shows this correlation.

The converted value settles to 100 % within 80 ms and is updated every 10 ms when
4-channel mode is set. The channel and module cycle times are always identical, as the
module does not change between the channels of a group: 10 ms.
Channel conversion time = channel cycle time = module cycle time = 10 ms

6.10 Analog input module SM 331; AI 8 x TC; (6ES7331-7PF11-0AB0)
Cycle time extension due to wire-break monitoring
The wire-break monitoring software function of the module is available in all operating
modes.
The 8-channel mode (hardware or software filter modes) extends module cycle times by
4 ms, irrespective of the number of channels at which wire-break monitoring is enabled.
In 4-channel mode (hardware filter), the module interrupts processing of input data for the
duration of 170 ms and performs a line continuity check. That is, each line continuity check
extends the module cycle time by 93 ms.
Unused channels
Set the "disabled" value at the "measurement type" parameter for unused channels. This
setting reduces module cycle times.
You must short-circuit all unused channels of an active group, that is, you short-circuit the
positive and negative inputs of these channels.
Effect of this measure:
● Measurement errors at the channels used of a group are avoided
● Diagnostic messages from the unused channel in a group are suppressed
Short-circuit to M or L
The module does not suffer any damage if you short-circuit an input channel to M or L.. The
channel continues to output valid data and does not report a diagnostics event.
Special features of channel groups with respect to hardware interrupts upon limit violation
You can set the high and low limits triggering hardware interrupts separately for each
channel in STEP 7.
End of cycle interrupt
You can synchronize a process with the conversion cycle of the module by enabling the end
of cycle interrupt. The interrupt is set when all active channels have been converted.

If no Pt 100 resistance thermometer is available, the reference junction can be read using a
thermoresistor module. The measured temperature values are then transferred to module
AI 6 x TC via data record 2 (for details on the structure of data record 2, see the figure

6.11 Analog input module SM 331, AI 6 x TC isolated (6ES7331-7PE10-0AB0)
Technical specifications
Wiring of the signal sensors
using a 40-pin front connector
1. The integration time of the module at 400 Hz suppression is displayed in HW Config as 2.5 ms. To achieve the required
resolution of 15 bits (plus sign), an integration time of 10 ms is needed.
2. If wire-break monitoring is active, the module cycle is performed within the basic conversion time
+ 65 ms. and the reaction time to a change in the step input is no longer than twice the module-cycle time. If wire-break
monitoring is inactive, in the best-case scenario the module-cycle time is exactly the same as the integration time.
However, this time interval cannot be guaranteed due to the time needed to process the input channels. If wire-break
monitoring is inactive, the reaction time to a change in the step input is no longer than four times the integration time.
3. Common mode interference suppression and crosstalk between inputs are executed at > 130 dB, if 10 Hz, 50 Hz, or
60 Hz has been selected as the interference frequency. If 400 Hz has been selected as the interference frequency,
common mode interference suppression and crosstalk between inputs are implemented at > 110 dB
4. The operational limit comprises only the basic error of the analog input at Ta = 25 °C and the total temperature error.
The total error must include the compensation error of the cold reference junction. Internal compensation of the
reference junction = max. 1.5 °C External compensation of the reference junction = accuracy of the external
thermoresistor used ± 0.1 °C. External compensation of the reference junction, which maintains the reference junction
at 0 °C or 50 °C = accuracy of temperature control for the reference junction.
5. An integration time of 100 ms is recommended for thermocouple measurements. Integration times set lower than this
will result in a higher repeat-accuracy error for the temperature measurements.
6. With thermocouple type B, a missing compensation of the reference junction temperature has no significant effect
owing to its slight increase from approx. 0 °C to 40 °C. With missing compensation and set measuring type
"Compensation to 0 °C", the deviation with thermocouple type B at measuring temperatures between:
–
700 °C and 1820 °C is < 0.5 °C
–
500 °C and 700 °C is < 0.7 °C.
If the reference junction temperature is approximately that of the module temperature, "internal compensation" should
be set. As a result, the error for the temperature range from 500 °C to 1820 °C is reduced to < 0.5 °C.

6.11 Analog input module SM 331, AI 6 x TC isolated (6ES7331-7PE10-0AB0)
Short-circuit to M or L
The module does not suffer any damage if you short-circuit an input channel to M or L. The
channel continues to output valid data and does not report a diagnostics event.
Special features of channel groups with respect to hardware interrupts when limit is exceeded
You can set the high and low limits triggering hardware interrupts separately for each
channel in STEP 7.

Startup characteristics and compensation time monitoring (watchdog) for external cold spot
compensation via remote thermoresistor
When the module starts up, all inputs report an overflow (32767). Once a compensation
value has been received via data record 2, the module starts to read the TC inputs and to
output correct data. If the module does not receive any data from data record 2 within
5 minutes of startup, a reference channel fault is reported in the standard channel
diagnostics data. If enabled, a diagnostic interrupt is sent.
The module features time monitoring (watchdog) set to 5 minutes, which is reset when a new
compensation value is received via data record 2. If the module does not receive any data
from data record 2 within the 5 minute interval set for the time-monitoring function in normal
operation, a reference channel fault is reported in the standard channel diagnostics data. If
enabled, a diagnostic interrupt is sent.
Internal calibration while the process is running
The module can compensate most of the internal temperature-drift errors. Internal calibration
while the process is running is always executed after startup, when parameters are
reassigned, and when the power is switched on/off. Once the relevant parameters have
been activated, internal calibration while the process is running is also performed if the
ambient temperature at the module changes by 5 degrees Celsius. Enabling calibration while
the process is running interrupts the module I/O cycle until calibration is complete. The
duration of the interruption depends on the programmed interference frequency; see the
table below for information about this relationship.

Calibration while the process is running should be activated to ensure measuring accuracy
over a long period of time. Some applications do not permit an interruption of the I/O cycle.
In such cases, you can disable the parameter for calibration while the process is running,
although this will result in less accurate measurements over time. The parameter for
calibration is activated as standard while the process is running.
Compensation of the reference junction
If the measuring point is exposed to a different temperature than the free ends of the
thermocouple (connection point), a voltage known as the thermoelectric voltage arises
between the free ends.
The level of the thermoelectric voltage depends on the difference between the temperature
at the measuring point and that at the free ends, as well as on the type of materials
combined in the thermocouple. Because a thermocouple always detects any temperature
difference, the free ends at the reference junction must be maintained at a certain
temperature to determine the temperature at the measuring point.

6.11 Analog input module SM 331, AI 6 x TC isolated (6ES7331-7PE10-0AB0)
External compensation of the reference junction via remote thermoresistor
The reference-junction temperature can also be measured via an external module and
transferred to the AI 6 x TC isolated module by means of SFC 58 in data record 2 (DR2).
The permitted reference temperature corresponds to the Pt100 climatic temperature range
for platinum thermoresistors.
-145.0 °C ≤ tref ≤+155.0 °C
-229.0 °F < tref <+311.0 °F
+128.2 K < tref <+327.6 K
The Kelvin measurement is only limited to 327.6 if the reference temperature is output in
technical units. If the reference temperature is reported in standard units, the Kelvin
measurement limit is 428.2 K.
If a reference value above the permitted temperature limit is received in DR2, it will cause a
reference channel fault, which is displayed in the standard channel diagnostic data. If
enabled, a diagnostic interrupt is sent.
Note
If an analog input module such as AI 8 x thermoresistor is used to measure the referencejunction temperature, the thermoresistor module parameters for the output structure and the
measuring accuracy must be represented by bytes 0 and 1 in data record 2. This is shown in
the figure "Structure of data record 2 for SM 331; AI 6 x TC". If the external thermoresistor
module does not provide correct information about data structure and scaling, it will lead to
inaccurate measurements being output by the isolated SM 331; AI 6 x TC module.

6.11 Analog input module SM 331, AI 6 x TC isolated (6ES7331-7PE10-0AB0)
Compensation of the thermocouple via an external Pt100 element with external thermoresistor
module
Because of the flexible structure of data record 2, you can use a separate external Pt100
element for each channel. In addition, the channels can also be grouped together by means
of the user application in such a way that they all use the same external Pt100. This simply
requires the same temperature value to be specified in DR2 for all the channels which use
the same reference temperature.
Note
Reference-junction compensation also results in an error in the temperature measured by
the isolated AI 6 x TC module. For this reason, great care must be taken when detecting the
reference junction. To keep this error to an absolute minimum, the reference-junction
temperature must remain as constant as possible.
Example: Transfer of a temperature value as a cold-spot temperature for channels 0 to 5, from a
thermoresistor module to AI 6 x TC:
Input address of AI 6 x TC: 238 (module address)
Input address of the thermoresistor: 128 (channel address)

6.11.4
Firmware update via HW Config for analog input module SM 331; AI 6 x TC
Introduction
Depending on the available comaptible function updates, the module AL 6 x TC can be
updated to the newest firmware version.
The most recent firmware versions are available from your Siemens representative or from
the Internet (http://www.siemens.com/automation/service&support).
Requirements
● STEP 7 V 5.4 SP4 (HSP0158) or higher
● For central use of the module Al 6 x TC in a S7-300, the firmware update must occur in
the CPU-operating mode STOP. If the CPU is in the RUN operating mode, it may result in
unexpected behavior and the module will first be available again after a network
off/network on.
● If the module Al 6 x TC is set in a distributed IO device ET 200M, a firmware update is
also possible in the CPU-operating mode RUN.

6.11.6
Calibration of analog input module SM 331; AI 6 x TC
Introduction
The SM 331 is calibrated at the factory and complies with the specified accuracy values. As
a rule, there is no need to recalibrate the module.
With certain systems, it may be advisable or even a requirement laid down in standards (as
required by particular institutions in the food and beverage or pharmaceutical industries) to
recalibrate the module once it has been integrated into the system, for example, at
specific time intervals.
Particularly in systems where sensors detect and/or process relatively low voltages and/or
currents, it may be advisable to perform recalibration when the module is in the system
including all connected cables. This approach compensates any influence by cables and/or
temperature.
If you carry out a calibration procedure, new calibration values are detected and saved
retentively on the module. This means that the calibration values determined for the module
at the factory prior to delivery are not lost when users perform their own calibration work.
You can revert to these original calibration values at any time.
Note
The calibration values from each channel are saved retentively on the module for a specific
measuring range, which means they only apply to the measuring range in which the user
calibration work was performed.
If the parameters of a channel which has active user-calibration values are reassigned to
change the measuring range, the calibration values saved at the factory for this channel and
this measuring range are used from this point on.
However, the user-calibration values still remain in the memory; they are not overwritten until
the user calibrates the channel again. But if the original measuring range is reset for this
channel without the user performing the calibration procedure again, the user-calibration
values which have already been established become effective once more.
Requirements
The calibration function can only be used in a distributed installation and in conjunction with
the SIMATIC PDM ("Process Device Manager").
The following requirements must be met to use the module calibration functions: SIMATIC
PDM V6.0 + SP3 or higher + HF2 in conjunction with HSP158, or SIMATIC PDM V6.0 + SP4
or higher, and the EDD for the ET 200M,
"DP_IOSystem_Siemens_ET200M_Module.Device", Version V1.1.10 or higher
User calibration is not permitted if the AI 6 x TC module is running in redundant mode.

Launching the calibration function
The following diagrams show the sequence of a user calibration in SIMATIC PDM V6.0 +
SP5. More recent versions of SIMATIC PDM can deviate from the content of these
diagrams.
The module calibration function is launched in the SIMATIC PDM via <Device ⇒ Calibration>
for the selected module.

Calibration function
Once the calibration function has been launched, the calibration start screen appears. Each
time a new channel is selected, the module reads the following general data and calibration
values:
General data:
● Measuring range: Currently programmed measuring range for the selected channel
● Date: Date and time when the displayed calibration values were determined
● Calibration: Indicates whether the currently active calibration values are factory-set or
user values
Calibration values:
● Offset: Currently active offset for the analog digital converter
● Gain: Currently active gain for the analog digital converter
● CJ Offset: Currently active temperature offset for the internal reference-temperature
sensor (only relevant for TC-IL thermocouples)
● TC Gain: Currently active gain for recording the temperature (only relevant for TC-IL,
TC-EL, TC-L00C, and TC-L50C thermocouples)

Options
Now you can:
● Start user calibration for the selected channel
-> "User calibration" button
● Reset the calibration values set at the factory for the selected channel
-> "Reset to factory setting" button
● Cancel the calibration function
-> "Cancel" button
Note
If you reset the currently active channel to its factory settings, the original calibration
values saved on the module when it was delivered become valid again. Any usercalibration values which may exist for this channel are then lost. You cannot restore these
user-calibration values.
User calibration
User calibration is started for the selected channel by pressing the "User calibration" button.
A 24 V load voltage must be applied at the module for calibration.
The user calibration function re-establishes the calibration values required by the selected
channel in accordance with the measuring range which has been programmed for that
channel.
Calibration can be executed in the CPU's RUN or STOP operating modes. Please note that
in the CPU's RUN operating mode, the module does not return any correct analog values to
the process for the duration of the calibration.
Note
While user calibration is ongoing, none of the module channels can handle new process
values.
• All analog input values of the module are set to 0x7FFF ("invalid analog value") until
calibration is complete.
• All channels indicate this status by means of a corresponding channel-diagnostic function
using the second type of diagnosis (see Section 1.7, "Diagnostics of the analog input
module SM 331; AI 6 x TC isolated").

Analog modules
6.11 Analog input module SM 331, AI 6 x TC isolated (6ES7331-7PE10-0AB0)
The previously selected channel is calibrated using the calibration display which is output.
Calibration consists of several different steps, during which the individual calibration values
are determined.
● If a fault occurs during calibration or if new parameters are assigned to the module, the
calibration of the relevant channel is canceled and the most recently active calibration
values for the channel become effective once more. All of the calibration values recorded
up to this point are lost. The module can now handle the current process values once
again.
● Calibration can be canceled at any time once it has been started. Following cancelation,
the previously active calibration values take effect again and the calibration values
recorded up to this point are lost. The module can now handle the current process values
once again.
You must provide a voltage and/or temperature during user calibration. You do this by using
the appropriate external wiring and an external voltage/temperature transmitter. As shown in
the figure "User-calibration status", the "Instructions" field indicates the numbers of the pins
where the calibration stimulus can be applied. The first pin number corresponds to the
positive terminal, the second to the negative terminal. The accuracy of the calibration
depends on the accuracy of the voltage/temperature supplied. To ensure that the module
maintains the specified measuring accuracy following user calibration, the
voltage/temperature provided must demonstrate an accuracy at least twice that defined for
the module. Inaccurate voltages or temperatures will result in an incorrect calibration.

Introduction
You can configure the outputs for operation as voltage or current outputs, or disable them.
You program the outputs at the "output type" parameter in STEP 7.
Output type "Voltage" and output range "± 10 V" are set by default at the module. You can
always use this combination of output type and range without having to program the SM 332;
AO 8 x 12 Bit in STEP 7.

Assigning parameters to channels
The parameters can be set separately at each output channel of SM 332; AO 8 x 12 Bit. You
can assign separate parameters to each output channel.
Assign the parameters you set at the SFCs in the user program to the channel groups. Each
output channel of SM 332; AO 8 x 12 Bit is thus assigned to a channel group, i.e. output
channel 0 > channel group 0, for example.
Note
The output may carry invalid interim values if you modify output ranges while SM 332;
AO 8 x 12 bit is in RUN.

Assigning parameters to channels
The parameters can be set separately at each output channel of SM 332; AO 4 x 16 Bit. You
can assign separate parameters to each output channel.
Assign the parameters you set at the SFCs in the user program to the channel groups. Each
output channel of SM 332; AO 4 x 16 Bit is thus assigned to a channel group, i.e. output
channel 0 > channel group 0, for example.
Note
The output may carry invalid interim values if you modify output ranges while SM 332;
AO 4 x 16 bit is in RUN.

6.13.3
Isochronous mode
Properties
Reproducible reaction times (i.e. of the same length) are achieved in a SIMATIC system by
means of a constant DP bus cycle, and synchronization of the single cyclic processes
outlined below:
● Independent user program cycle. The length of the cycle time may vary due to non-cyclic
program branching.
● Independent and variable DP cycle on the PROFIBUS subnet
● Cyclic operation of the backplane bus of the DP slave.
● Cyclic signal preparation and conversion at the electronic modules of the DP slave.
The constant DP cycle runs in synchronism and at the same length. The CPU run levels
(OB61 to OB64) and isochronous IO are synchronized with this cycle. I/O data are therefore
transferred at defined and constant intervals (isochronous mode.) Maximum flutter: ±50 μs.
Requirements
● The DP master and slave must support isochronous mode. You require STEP 7 V5.2 or
higher.
Mode of operation: Isochronous mode
Conditions of isochronous mode:
Processing and activation time TWA between reading the output value to the
transfer buffer and loading it into the D/A converter for output
750 µs
TDPmin
1100 µs

Definition of isochronous mode
Within the time TO - TWA, the module reads the output data and saves these internally. After
the internal processing time of each channel, the results are written to the various DACs.
Further information
For further information on isochronous mode, refer to the STEP 7 Online Help, in the
operating instructions ET 200M Distributed IO System

Parameter reassignment in RUN
If you reassign parameters in RUN, the following special characteristic applies.
SF LED is lit:
If a diagnostics was pending prior to reconfiguration, the SF LEDs (on CPU, IM or module)
may be lit even though diagnostics is no longer pending and the module is operating
correctly.
Solution:
● Only assign new parameters if no diagnostics is pending, or
● unplug module and plug it in again.

Output ranges of SM 332; AO 4 x 12 Bit
Introduction
You can configure the outputs for operation as voltage or current outputs, or disable them.
You program the outputs at the "output type" parameter in STEP 7.
The output type "Voltage" and output range "± 10 V" are set by default at the module. You
can always use this combination of output type and range without having to program the
SM 332; AO 4 x 12 Bit in STEP 7.

Assigning parameters to channels
The parameters can be set separately at each output channel of SM 332; AO 4 x 12 Bit. You
can assign separate parameters to each output channel.
Assign the parameters you set at the SFCs in the user program to the channel groups. Each
output channel of SM 332; AO 4 x 12 Bit is thus assigned to a channel group, i.e. output
channel 0 > channel group 0, for example.
Note
The output may carry incorrect interim values if you modify output ranges while SM 332;
AO 4 x 12 Bit is in RUN.

Unused channels
To take unused output channels of SM 332; AO 4 x 12 Bit off power, set the "disabled"
argument at the "output type" parameter. Disabled channels do not have to be wired.
Line continuity check
SM 332; AO 4 x 12 Bit only performs a line continuity check at the current outputs.
In output ranges 0 mA to 20mA and ±20 mA, a "reliable" wire-break check is not possible for
output values of-20s to ±200 µA.
Short-circuit test
SM 332; AO 4 x 12 Bit only performs a short-circuit test at the voltage outputs.
Substitute values
You can configure the SM 332; AO 4 x 12 Bit for CPU STOP mode as follows: Outputs off
power, hold last value or set substitute values. The set substitute values must lie within the
output range.

Terminal assignment
The diagrams below show various wiring options.
Note
Note when wiring the SM 334:
• analog ground MANA(terminal 15 or 18) is interconnected with chassis ground M of the
CPU or interface module IM. Use a cable with a conductor cross-section of at least
1 mm2.
The module will shut down if the ground connection between MANA and M is missing.
Inputs are read with 7FFFH, and outputs return a value of 0. The module may be
destroyed if operated without ground over a longer period of time.
• the supply voltage for the CPU and/or the interface module (IM) may not be connected
with reversed polarity. Reverse polarity will inevitably lead to the destruction of the
module, because MANA develops an impermissible high potential (+24 V.)

Measurement and output ranges of SM 334; AI 4/ AO 2 x 8/8 bit
Measuring ranges
SM 334; AI 4/AO 2 x 8/8 Bit provides the 0 V to 10 V and 0 mA to 20 mA measuring ranges.
By contrast to the other analog modules, the SM 334 has a lower resolution and no negative
measuring ranges. Make allowances for this feature when reading the measured value
tables Analog value representation in the ± 1 V to ± 10 V measuring ranges and Analog
value representation in the 0 mA to 20 mA and 4 mA to 20 mA measuring ranges.
Output ranges
SM 334; AI 4/AO 2 x 8/8 Bit provides the 0 V to 10 V and 0 mA to 20 mA output ranges.
Compared to the other analog modules, the SM 334 has a lower resolution, and its analog
outputs do not have any overshoot ranges. Make allowances for this feature when reading
the tables Analog value representation in the 0 V to 10 V and 1 V to 5 V output ranges and
Analog value representation in the 0 mA to 20 mA and 4 mA to 20 mA output ranges.

Additional information on SM 334; AI 4/AO2 x 8/8 Bit
Unused channels
Always short-circuit unused input channels, and connect these to MANA. This optimizes
interference immunity of the analog input module.
Leave unused output channels open.

Measurement types and ranges
Introduction
You can configure the outputs for operation as voltage or current outputs, or disable these.
You can wire the outputs as voltage outputs, or disable these.
Program the outputs at the "measurement type" AND output type" parameters in STEP 7.
Input defaults
The "thermoelectric resistance (linear, 4-wire connection)" measurement type and "Pt 100
Klima" measuring range are set by default at the module. You can use these default settings
without having to program the SM 334; AI 4/AO 2 x12 Bit in STEP 7.
Options of wiring the input channels
You can wire the input channels of SM 334; AI 4/AO 2 x 12 Bit in the following combinations:
Channel
Wiring versions
Channels 0 and 1 •
•
Channels 2 and 3 •
2 x temperature or

Unused channels
Set the "disabled" value at the "measurement type" parameter for unused input channels.
This setting reduces module cycle times.
Always short-circuit unused input channels, and connect these to MANA. This optimizes
interference immunity of the analog input module.
To take the unused output channels of SM 334; AI 4/AO 2 x 12 Bit off power, always set
"disabled" argument at the "output type" parameter, and leave the connection open.

Properties
Properties of simulator module SM 374; IN/OUT 16:
● Simulation of:
– 16 inputs or

● Status displays for the simulation of inputs and outputs
● Function adjustable with screwdriver
Note
Do not operate the function selection switch in RUN!
Configuration in STEP 7
The simulator module SM 374; IN/OUT 16 is not included in the STEP 7 module catalog.
STEP 7 therefore does not recognize the SM 374 order number. "Simulate" the simulator
module function required for your configuration as follows:
● To use the SM 374 with 16 inputs, define the order number of a digital input module with
16 inputs in STEP 7,
for example: 6ES7321-1BH02-0AA0
● To use the SM 374 with 16 outputs, define the order number of a digital output module
with 16 outputs in STEP 7,
for example: 6ES7322-1BH01-0AA0
● To use the SM 374 with 8 inputs and 8 outputs, define the order number of a digital
input/output module with 8 inputs and 8 outputs in STEP 7,
for example: 6ES7323-1BH00-0AA0

7.3
Dummy module DM 370; (6ES7370-0AA01-0AA0)
Order number
6ES7 370-0AA01-0AA0
Properties
The dummy module DM 370 reserves a slot for a non-configured module. It can be used as
dummy module for:
● Interface modules (without reservation of address space)
● Non-configured signal modules (with reservation of address space)
● Modules which occupy 2 slots (with reservation of address space)
When replacing the dummy module with another S7-300 module, the mechanical assembly
and address assignment/addressing of the entire configuration remain unchanged.
Configuration in STEP 7
Configure the DM 370 dummy module in STEP 7 only if you module for a programmed
signal module. If the module reserves the slot for an interface module, you can discard
module configuration in STEP 7.
Modules which occupy 2 slots
Install two dummy modules for modules which occupy 2 slots. You only reserve the address
space using the dummy module in slot "x", rather than the dummy module in slot "x + 1". For
details of the procedure, see the table below.
The rack can receive up to 8 modules (SM/FM/CP.) When using two dummy modules to

Isochronous mode
Note
For basic information on isochronous mode, refer to the SIMATIC; isochronous mode
function manual.
Hardware requirements
To operate SM 338 in isochronous mode, you need:
● a CPU which supports isochronous mode
● a DP master which supports the constant bus cycle
● a slave interface (IM 153-x) which supports isochronous mode
Properties
SM 338 operates in non-isochronous or isochronous mode, depending on system
parameters.
In isochronous mode, data are exchanged between the DP master and SM 338 in
synchronism to the PROFIBUS DP cycle.
In isochronous mode, all 16 bytes of the feedback interface are consistent.
If synchronism is lost due to disturbance or failure/delay of Global Control (GC), the SM 338
resumes isochronous mode at the next cycle without error reaction.
If synchronism is lost, the feedback interface is not updated.

Wiring rules
Important rules to observe wiring the module:
● Ground of the encoder supply is connected to CPU ground potential. Thus, establish a
low impedance connection between pin 2 of SM 338 (M) and CPU ground.
● Always use shielded twisted-pair cable to wire encoder signals (pins 3 to 14.) Connect
both ends of the shielding.
Use the shield connection element to terminate the shielding on SM 338 (order number
6ES7390-5AA00-0AA0).
● Connect an external power supply if the maximum output current (900 mA) of the
encoder supply is exceeded.

7.4.3
Functions of SM 338; POS-INPUT; encoder value acquisition
7.4.3.1
Encoder value acquisition
The absolute value encoder transfers its values in frames to the SM 338. The SM 338
initiates the frame transfer.
● In non-isochronous mode, the encoder values are acquired cyclically.
● In isochronous mode, the encoder values are acquired in synchronism with the
PROFIBUS DP cycle at each Ti.
Cyclic encoder value acquisition
The SM 338 always initiates a frame transfer at the end of the programmed monoflop time.
Asynchronously to these cyclic frames, the SM 338 processes the acquired encoder values
cyclically, based on its refresh rate (refer to the chapter "Technical data of SM 338;
POS-INPUT (Page 537)").
Thus, cyclic acquisition returns encoder values of different ages. The difference between the
min./max. age represents the jitter (refer to the chapter "Technical data of SM 338;
POS-INPUT (Page 537)".)
Isochronous encoder value acquisition
Isochronous encoder values acquisition is automatically set when the DP master system
operates with active constant bus cycle, and the DP slave is in synchronism with the DP
cycle.
SM 338 initiates a frame transfer in each
PROFIBUS DP cycle, at the time Ti.
The SM 338 processes the transferred encoder values in synchronism with the
PROFIBUS DP cycle.
7.4.3.2
Gray code/binary code converter
When Gray code is set, the Gray code value returned by the absolute value encoder is
converted into binary code. When binary code is set, the values returned by the encoder
remain unchanged.
Note
When you set Gray code, the SM 338 always converts the entire encoder value (13, 21,
25 bits). As a result, any leading special bits will influence the encoder value, and the
appended bits may be corrupted.

Other signal modules
7.4 Position decoder module SM 338; POS-INPUT; (6ES7338-4BC01-0AB0)
7.4.3.3
Transferred encoder value and scaling
The transferred encoder value contains the encoder position of the absolute value encoder.
In addition to the encoder position, the encoder transfers additional bits located before and
after the encoder position, depending on the encoder used.
The SM 338 determines the encoder position based on the following settings:
● Scaling, places (0..12), or
● scaling, steps / revolution
Scaling, places
Scaling determines the position of the encoder value at the feedback interface.
● "Places" = 1, 2....12 indicates that appended irrelevant bits in the encoder value are
shifted out, and the encoder value is right-aligned in the address area (see the example
below.)
● "Places" = 0 determines that appended bits are retained and available for evaluation.
This may be useful when the absolute value encoder used transfers information in the
appended bits (see manufacturer specifications) which you want to evaluate. Refer also
to chapter "Gray code/binary code converter (Page 527)".
Steps per revolution parameter
Up to 13 bits are available for the steps per revolution parameter. The resultant number of
steps per revolution is displayed automatically according to the "Places" setting.

7.4.3.4
Freeze function
The freeze function "freezes" the actual encoder values of SM 338. The freeze function is
coupled to the digital inputs DI 0 and DI 1 of SM 338.
The freeze function is triggered by a signal transition (positive edge) a DI 0 or DI 1. Bit 31 = 1
(output address) identifies a frozen encoder value. You can freeze one, two or three encoder
values using one digital input.
Enable the freeze function by setting the corresponding parameters in STEP 7 .
To allows their event-triggered evaluation, the encoder values are retained until the freeze
function is terminated.
Terminating the freeze function
The freeze function must be terminated separately at each encoder input. You acknowledge
the function in the user program by using STEP 7 operation T PAB to set bit 0, 1 or 2 to "xyz"
according to the channel (Program example: refer to chapter "Auto-Hotspot").
The acknowledgement resets bit 31 of the corresponding encoder value, and initiates a
refresh of the encoder values. You can freeze the encoder values again after you cleared the
ACK bit at the output address of the module.
In isochronous mode, the acknowledgement is processed at the time To. From this point on,
you can freeze the encoder values again by setting the digital inputs.
Note
The Freeze function is acknowledged automatically when you assign new parameters with
different arguments to the relevant channel (refer to chapter "Auto-Hotspot").
If the parameter are identical the Freeze function remains unaffected.
7.4.4
Parametrization SM 338 POS-INPUT
You parameterize the SM 338; POS-INPUT in STEP 7. Always parameterize the module
while the CPU is in STOP mode.
After you completed the parameter assignment, download the parameters from the PG to the
CPU. At its next STOP → RUN transition, the CPU transfers the parameters to the SM 338.
New parameters can not be assigned by the user program.

Diagnostics of SM 338; POS-INPUT
Introduction
The SM 338 provides diagnostics messages, i.e. it always provides all diagnostics messages
without user intervention.
Reactions to a diagnostic message in STEP 7
Actions initiated by diagnostic messages:
● The diagnostic message is entered in the diagnosis of the module and forwarded to the
CPU.
● The SF LED on the module is lit.
● If you have set "Enable Diagnostic Interrupt" in STEP 7, the system triggers a diagnostic
interrupt and calls OB 82.
Reading diagnostic messages
You can read detailed diagnostic messages using SFCs in the user program (refer to section
Diagnostics data of SM 338; POS-INPUT (Page 622)).
You can view the cause of the error in the module diagnostics data in STEP 7 (refer to the
STEP 7 Online Help.)
Diagnostic message using the SF LED
The SM 338 indicates errors at its SF LED (group error LED.) The
SF LED lights up when the SM 338 generates a diagnostic message. It goes dark after all
error states are cleared.
The SF LED also lights up to indicate external errors (short-circuit at the encoder supply),
regardless of the CPU operating state (at POWER ON.)
The SF LED lights up temporarily at startup, during the self test of SM 338.

SM 338; POS INPUT - Interrupts
Introduction
This chapter describes the interrupt reaction of SM 338; POS-INPUT. The SM 338 can
trigger diagnostic interrupts.
For detailed information on the OBs and SFCs mentioned below, refer to the STEP 7 Online
Help.
Enabling interrupts
There is no default interrupt setting, i.e. interrupts are disabled if not set accordingly. You
configure the interrupt enable parameter in STEP 7 (refer to chapter "Parametrization
SM 338 POS-INPUT (Page 530)").
Diagnostic interrupt
If you have enabled diagnostic interrupts, the incoming error events (initial occurrence of the
error) and outgoing error events (message after troubleshooting) are reported by means of
interrupts.
The CPU interrupts user program execution, and executes diagnostic interrupt OB82.
You can call SFC 51 or 59 in OB82 in the user program to view detailed diagnostic data
output by the module.
Diagnostics data remain consistent until the program exits OB 82. The module
acknowledges the diagnostic interrupt when the program exits OB82.

Parameter sets of signal modules
A.1
A
Principles of programming signal modules in the user program
Parameter assignment in the user program
You have programmed the modules in STEP 7.
In the user program, you can use a SFC:
● to assign new parameters to the module, and
● transfer the parameters from the CPU to the addressed signal module
Parameters are stored in data records
The signal module parameters are written to data records 0 and 1; for certain analog input
modules, these are also written to data record 128.
Editable parameters
You can edit the parameters of data record 1, and then transfer these to the signal module
using SFC55. The CPU parameters are not changed by this action!
You cannot modify any parameters of data record 0 in the user program.
SFCs for programming
SFCs available for programming signal modules in the user program:
Table A- 1
SFCs for programming signal modules
SFC no.
Identifier
Application
55
WR_PARM
Transfer the programmable parameters (data record 1 and 28) to the addressed
signal module.
56
WR_DPARM
Transfer the parameters (data record 0, 1 or 128) from the CPU to the addressed
signal module.
57
PARM_MOD
Transfer all parameters (data record 0, 1 and 128) from the CPU to the addressed
signal module.

Evaluating diagnostic data of signal modules in the user program
Introduction
This appendix describes the diagnostic data structure in system data. You should be
sufficiently familiar with this structure if you want to evaluate the diagnostics data of the
signal module in the STEP 7 user program.
Diagnostics data are saved to data records
The diagnostics data for a module is stored in data records 0 and 1.
● Data record 0 contains 4 bytes of diagnostics data describing the current state of the
module.
● Data record 1 contains the 4 bytes of diagnostics data also stored in data record 0, plus
additional module-specific diagnostics data, which describes the status of a channel or a
channel group.
Further references
For detailed information on the evaluation of the diagnostics data of signal modules in the
user program and on corresponding SFCs, refer to the STEP 7 manuals.

Byte 7 of diagnostics data
The channel fault vector is at least 1 byte long. For modules with more than 8 channels, the
channel fault vector occupies several bytes.
The channel-specific diagnostics data comes after the channel fault vector; refer to section
Channel-specific diagnostics data (Page 614).
If another channel type is available (see Figure "Bytes 4 to 6 of diagnostics data"), the
channel type with the same structure as that described above (channel type, length of
diagnostics data, number of channels of the same type, channel fault vector, channelspecific diagnostics data of the channel type) follows after the channel-specific diagnostics
data.

Channel-specific diagnostics data
Introduction
The channel-specific diagnostics data follows the channel fault vector. The number of bytes
used for channel-specific diagnostics for each channel is based on the number of bits
entered in byte 5 "length of diagnostic information".
The figures below show the assignment of the diagnostics byte of a module-specific channel
or channel group. General rule: A fault is indicated by a logic "1" at the relevant bit.
You will find a description of possible causes of problems and appropriate remedies in the
section titled "Diagnostics of the modules".

Directive on handling Electrostatic-Sensitive Devices
(ESD)

Introduction
In this appendix, we explain
● the meaning of "electrostatic-sensitive devices"
● the precautions you must take when handling and working with electrostatic sensitive
modules.
E.1
Definition of ESD
Definition
All electronic modules are equipped with large-scale integrated ICs or components. Due to
their design, these electronic elements are highly sensitive to overvoltage, and thus to any
electrostatic discharge.
These Electrostatic Sensitive Ddevices/Modules are commonly abbreviated ESD. The
common international designation ESD stands for Electrostatic Sensitive Device.
ESD modules are identified by the following symbol:
CAUTION
ESD devices can be destroyed by voltages well below the threshold of human perception.
These static voltages develop when you touch a component or electrical connection of a
device without having drained the static charges present on your body. The electrostatic
discharge current may lead to latent failure of a module, that is, this damage may not be
significant immediately, but in operation may cause malfunction.

E.3 Basic protective measures against electrostatic discharge
E.3
Basic protective measures against electrostatic discharge
Ensure sufficient grounding
Make sure all persons, workplaces and packaging are sufficiently grounded when handling
ESD components. This prevents electrostatic charge.
Avoid direct contact
You should only touch ESD components if unavoidable (for example, during maintenance
work). Handle the modules without touching any chip pins or PCB traces. In this way, the
discharged energy can not affect the sensitive devices.
Discharge your body before you start taking any measurements on a module. Do so by
touching grounded metallic parts. Always use grounded measuring instruments.

Diagnostic interrupt
Module diagnostics function report errors to the → CPU by means of diagnostic interrupts.
The CPU operating system calls OB 82 when a diagnostic interrupt is generated.
Diagnostics
Generic term for → System diagnostics, hardware error diagnostics, and user-specific
diagnostics.
Diagnostics buffer
The diagnostics buffer represents a backup memory in the CPU, used to store diagnostics
events in their order of occurrence.
In STEP 7 (PLC → Module status), the user can read data from the diagnostics buffer to
determine the precise cause of error.

Input delay
STEP 7 parameter for digital input modules. The input delay function is used to suppress
coupled disturbance. This includes pulse-shaped disturbance within the range from 0 ms to
the set input delay
The input delay tolerance is defined in the technical data of the module. The length of
suppressed pulse-shaped disturbance is determined by the length of the input delay.
The permissible input delay is determined by the line length between the encoder and the
module. Unshielded encoder supply lines of a grater length (more than 100 m) require a long
delay setting.
Integration time
STEP 7 parameter for analog input modules. The integration time is equivalent to the inverse
value of the → noise suppression frequency in ms.

measured values, in particular in the low voltage ranges, and when thermocouples are being
used. At this parameter, the user defines the mains frequency prevailing on his system.
Interrupt
SIMATIC S7 knows 28 different priority classes which control user program execution. Those
priority classes also include hardware interrupts, for example. When an interrupt is
generated, the operating system automatically calls an assigned OB which the user can
program to trigger a specific action (at an FB for example.)

2. Tag used to set one or several properties of a module. Each module is supplied with
default parameters which users may edit in STEP 7.
PG
→ Programming device
Process image
The CPU saves the signal states of analog IO modules to a process image.
We distinguish between the process image of inputs (PII) and outputs (PIO). The input
modules read the process image of inputs (PII) before the operating system executes the
user program. The operating system transfers the process image of outputs (PIO) to the
output modules at the end of program execution.
Product version
Differentiates products of the same order number. The product version is incremented in the
case of upwards compatible enhancements of functionality, production-specific changes (use
of new components/parts), and fixes.
Programming device
A programming device (PG) is a special compact PC (Personal Computer) suitable for use in
industry. A PG is fully equipped for programming SIMATIC automation systems.
Reference junction
When operating thermocouples on analog input modules: point of known temperature
(for example, → compensating box.)
Reference potential
Potential from which the voltages of participating circuits are derived and measured.
Repeat accuracy
Denotes the maximum deviation between measured/output values, if the same input or
output signal is repeatedly set. Repeat accuracy refers to the rated range of the module, and
applies to its settled temperature state.

Glossary
Repeater
Equipment used to amplify bus signals, and couple → bus segments across greater
distances
Resolution
Number of bits representing the value of analog modules in binary format. The resolution is
module-specific. It is also determined by the → integration time of analog input modules. The
precision of the measured value resolution increases with the length of the integration time.
The maximum resolution is 16 bits + sign.
Response to open thermocouple
STEP 7 parameter for analog input modules operating with thermocouples. This parameter
defines whether the module outputs an "Overflow" (7FFFH) or "Underflow" (8000H) value
when it detects an open thermocouple.
Restart
At its restart (initiated by setting the mode selector switch from STOP to RUN, or after
POWER ON), the CPU first executes restart OB 100, and then continues with cyclic program
execution (OB1.)
During its restart, the CPU reads the → Process image of inputs (PIO), and then executes
the STEP 7 user program, starting at the first statement in OB1.
Retentivity
Data areas in data blocks (DBs), timers, counters and flags are considered retentive if their
content is not lost as a result of restart or power off.
Scaling
STEP 7 parameter for the SM 338; POS-INPUT position detection module. Scaling rightaligns the → Absolute encoder value in the address space; irrelevant places are discarded.
Segment
→ Bus segment
SFC
→ System Function
Signal module
Signal modules (SMs) form the interface between the process and the automation system.
These are available as digital and analog input/output and IO modules.

Glossary
Smoothing
STEP 7 parameter for analog input modules. The measured values are smoothed by digital
filtering. Users can select module-specific filter properties, i.e. none, low, medium or high.
The time constant of the digital filter increases in proportion to the degree of smoothing.
STARTUP
STARTUP mode initiates the transition from STOP to RUN mode. STARTUP can be
triggered by setting the → mode selector, by power on, or by an operator action on the
programming device. S7-300 performs a → restart.
Substitution value
Values output by faulty signal output modules to the process, or used to substitute a process
value of a faulty signal input module in the user program.
Users can program the substitute values in STEP 7 (hold last value, substitution value 0 or
1.) Those values must be set at the outputs when the CPU goes into STOP.
System diagnostics
Denotes the detection, evaluation and reporting of error events within the automation
system. Examples of such errors are: program errors, or module failure. System errors may
be indicated by LED displays, or in STEP 7.
System Function
A System Function (SFC) is an integral function of the CPU operating system, and can be
called in the STEP 7 user program as required.
Temperature coefficient
STEP 7 parameter for analog input modules, for temperature measurements taken with
resistance thermometers (RTD.) The selected temperature coefficient is specific to the
resistance thermometer being used (to DIN standard.)
Temperature error
Denotes the drift of measured/output values, caused by fluctuation of the ambient
temperature at an analog module. It is defined in % per Kelvin, relative to the rated range of
the analog module.
Temperature error of internal compensation
Only applies to the measurement of thermocouples. Defines the error to add to the actual
temperature error, when "internal comparison" mode is selected. The error is defined either
as a percentile value relative to the physical rated range of the analog module, or as an
absolute value in °C.

Glossary
Total current
Total current of all output channels of a digital output module.
ungrounded
no galvanic connection to ground potential
User program
Contains statements, tags and data for processing signals which can control a plant or
process. It is assigned to a programmable module (CPU, FM, for example) and can be
organized in smaller units (blocks).
Wirebreak
Parameter in STEP 7. A wirebreak check is used to monitor line continuity between the
encoder and input, or between the actuator and output. The module detects a wirebreak
based on a current flow at the appropriately programmed input/output.
