The WAGO I/O System
The WAGO I/O SYSTEM consists of various components which are capable of
providing modular and application specific fieldbus nodes for various fieldbusses.
I11.1 Setting up a fieldbus node with the WAGO I/O SYSTEM
General remark:
A fieldbus node consists in principle of a fieldbus coupler at the front end, a number of
special function modules and a termination module which is placed at the other end.
1 - Buscoupler
The Buscoupler forms the link between the fieldbus and the field devices with their I/O
functions. All control functions required for the faultless operation of the I/O functions
are carried out by the coupler. The connection to different fieldbus systems is
established by each of the corresponding Buscouplers, e.g. for PROFIBUS, INTERBUS
S, II/O LIGHTBUS, CAN, ModBus etc. In this way a change of the fieldbus system is
possible.
2 - Function modules
In the function modules, the incoming process data ais converted. Corresponding to the
different requirements, special function modules are available for a variety of functions.
There are digital and analog inputs and outputs and modules for special functions. The
modules are described in the following chapters.
3 - Termination module
A termination module is needed for faultless operation of the node. The termination
module is always placed as the last module in order to obtain a termination of the
fieldbus node. This module has no I/O function.

Assembly of the WAGO I/O System
All components of the system can be snapped directly on a carrier rail according to EN
50022 (DIN 35).
When snapping the analog or digital components onto the rail, no special sequence must
be observed. The secure positioning and connection of the individual function modules
and the coupler is provided by a snap-in system. This snap-in system provides automatic
interlocking onto the DIN rail assembly. It is always possible to remove a function
module or the Buscoupler from the assembly by pulling the orange pull-tab.
Please note, that the power supply of the field side as well as the data transmission are
interrupted. It has to be ensured that the interruption of PE will not put personnel or
equipment in danger.
With a CAGE CLAMP, conductors with a cross section of 0.08 to 2.5mm2 /AWG 18-14
can be connected. Vibration proof, fast and maintenance-free. You simply introduce a
screwdriver or an operating tool into the operating slot under the clamping unit. The
CAGE CLAMP spring is pressed down. You can now introduce the wire into the
clamping unit. Withdraw the operating tool and the conductor is automatically clamped.
PROFIBUS / Introduction
16.06.1999

:$*2Ç,2Ç6<67(0
The clamping force adjusts automatically to the conductor cross section. The flat
clamping face of the CAGE CLAMP spring presses the conductor against the current
bar without damage. Any deformation or movement of the conductor is compensated,
thus eliminating the risk of a loose connection. The contact point between conductor
and CAGE CLAMP is well protected against corrosive deterioration. This connection is
made fast and, furthermore, it is maintenance-free. There is no need for costly periodical
examination of the connections.
The supply modules of the WAGO I/O system are partly equipped with a fuse holder.
This fuse holder can be pulled out in order to break the circuit of the following modules.
To do so, you first have to insert a screwdriver into one of the slots on both sides in
order to pull out the front side of the fuse holder.
The front side now being hinged down makes it possible to remove or to insert the fuse.
After that, you lift up the front side again and push the fuse holder back into its original
position.

Buscoupler - Hardware
Ill. 2 Top view of the WAGO 750-301 PROFIBUS coupler DP/FMS
The 750-301 Profibus coupler consists of two major electronic sub systems:
left side:
This housing contains the electronics for the coupling to the bus, the processor
and the fieldbus connection. (ill. 2.1)
right side:
This housing contains the DC to DC converter and power distribution for the internal K
bus, local processor and external 24 V DC connections to other discrete I/O modules.
Illustration 2.2 identifies the 24 V DC connection points to supply voltage to I/O
modules. Illustration 2.3 identifies the ground connection.

Supply Voltage - Electronics
Ill. 3: Termination points for the power supply and the internal electronics
The nominal operating voltage of the Buscoupler and the control electronics in the
function modules is 5 V DC. The supply is connected to the first two CAGE CLAMPS
at the top of the coupler as seen in Ill. 3.
The 24 V DC supply voltage is converted by an internal voltage regulator (DC/DC
converter) and fed to the electronics (5 V DC). The electrical isolation of the external
bus system is made by utilizing an optocoupler.
Please note that the power connection for the control electronics in the function modules
is made automatically by the data contacts of the following module when it is snapped
on the assembly (ill. 3.1). The power supply to the attached I/O modules is provided by
gold-plated self-cleaning slide contacts. If an attached module is taken out of the
existing configuration, the connection via the K bus is broken and the coupler is able to
detect this.
WARNING
If a module is taken out of the existing configuration, there may be undefined states.
You should disconnect the power supply when changing anything in the configuration.

Supply Voltage - Field Side
Ill. 4: Termination points for the supply voltage - field side
The connection of the field side supply voltage is electrically isolated from the internal
electronics. Field side connection points have two CAGE CLAMPS which are always
connected to a power jumper contact (P.J.C.). In this way, the power supply is taken to
different points of the configuration.
It is possible to supply the following at the termination points (Ill. 4):
Volts: 24 V DC - Amps: 10 A DC
WARNING!
120 and 230 V AC can only be supplied via modules 750-609, 750-611 and 750-612!
The supply modules which are permanently integrated on the buscouplers, can be
supplied with 24 V DC only. The current on the power contacts should be max. 10 A.
The voltage is automatically supplied when the function modules are snapped together.
Self-cleaning power jumper contacts (P.J.C.s) ensure safe connections (Ill. 4). Female
contacts (current supply) are integrated in the buscoupler and I/O housings. The male
contacts on the buscoupler and I/O housings supply the voltage to the I/O modules when
inserted together from left to right.
The ground (earth) contact makes first and breaks last conforming to electrical standards
and can be used as protective grounding.
FUNCTION!
Depending on the I/O function, some modules do not have P.J.C.s. It is important to
note this when assembling a node. Many modules require field side power, many do
not. Please review the circuit diagrams of the individual modules. An additional power
supply module may be necessary.

:$*2Ç,2Ç6<67(0
When using the supply module 750-601/602, the field supply from the bus coupler is
interrupted. From that point a new power supply connection is necessary to provide DC
to any additional I/O modules.
WARNING!
The ground ( earth) field side contact should be disconnected when testing the isolation.
Otherwise the results could be wrong or the module could be destroyed.

All nodes are cabled in parallel. In order to guarantee data integrity to each node a
terminating resistor (the value depends on the resistance of the cable, e.g. 220 Ω) must
be placed across the data transmission lines at both master and slave points. Two 390 Ω
bias resistors must be connected with the 220 Ω resistor as shown in ill.6.
Station address:
The desired node address is set by means of the two encoding switches located on the
buscoupler. The address is adjustable in the range of 0....99.
The value of the switch at the bottom must be multiplied with 10, the value of the
switch at the top must be added and this number is the value of the address.

4 Profibus
The PROFIBUS-Specification (DIN 19245 part 1, 2) specifies the technical and
functional features for the networking of distributed field automation devices.
PROFIBUS distinguishes Master and Slave devices. The WAGO PROFIBUS couplers
belong to the Slave device catagory and transfer or accept messages to/from the Master.
With PROFIBUS DP Mono- or Multi-Master systems can be utilized. Thus a high
degree of flexibility can be obtained for the system configuration. A maximum of 126
devices (including Master) can be connected. The WAGO PROFIBUS coupler address
switches can be set to addresses between 0 and 99. 0,1 & 2 are typically reserved for
Master devices.
4.1
Interface Modules
The operation of the Master is carried out in most cases via a central control, like a PLC,
PC, or NC. The connection to the remote stations is made via interface modules.
Siemens PLC interface modules are:
- Siemens IM308B (Sinec L2DP) 1.5 MBaud
- Siemens IM308C (DP) 12 MBaud
- Siemens CP5431 (DP and FMS) 1.5 MBaud
Attention:
Note that IM308B allows only 32 input and output Bytes. Moreover it has to be noted
that the present versions of analog function modules must be considered as Input/Output
devices and therefore Input/Output addresses must both be entered per channel under
the 308B whereas the IM308C & CP5431 supports 244 Input and 244 Output Bytes.
The exact configuration description follows in the next chapters.
4.2
Configuration software
In order to make a connection between the PLC and the remote stations, the interface
modules must be configured with the individual node/station data.
The following software packages are available from Siemens:
- for IM308C the software COMWIN / Proficom (executable under WINDOWS 3.1,
Win95)
- for IM308B the software COMET200 (executable under DOS)

Configuration of the fieldbus node in the master connection
5.1
Master file of devices
The features of the devices are documented by the manufacturers under PROFIBUS DP in
the form of a master file of devices.
Structure, contents and coding of this device master file are standardized so that replacing
of any DP slaves with other devices from different manufacturers is possible.
The PUO (PROFIBUS User Organization) / PTO (PROFIBUS Trade Organization) updates
the device master file of all listed manufacturers.
The data in the device master file is read by the respective configuration software and the
corresponding settings are transmitted. The necessary entries and sequences of operation
are stated in the respective software user manuals. The necessary data is made available to
the master in the form of identification bytes.
An identification byte has the following format:

PROFIBUS / Configuration

:$*2Ç,2Ç6<67(0
Explanation:
Digital I/O’s have data placement inconsistancy because each bit includes its own
independend data.
Analog I/O’s have consistancy because the whole byte/word contains complete
information for the respective I/O module.
The WAGO PROFIBUS coupler is configured by identification bits/words for each
signal channel. When configuring the system care should given so that the analog
modules are configured from left to right byte by byte. This is critical to the proper
operation of the Master. After completion of the analog channels the digital modules can
be placed in any order.
The projected length of the data stream is determined by the amount of modules present.
Differing data legths will cause the buscoupler to reject that information.

Parameterization of the Fieldbus Station
Apart from the configuration described in the previous chapter, a stacking of the byte
protocol is required before a data exchange between the Master and Slaves can be made.
The parameter record of the WAGO fieldbus coupler comprises 32 parameterization
bytes, the first 7 bytes being reserved for the DP-log. By means of the following user
parameters, different operating modes of the coupler can be set. The table below shows

The process image Input/Output addresses shown can be selected within the allowable
range. The configuration of I/O modules in the software package is shown by the
examples in tables 2 and 3.
ATTENTION:
For Siemens S7 you have to use the function modules SFC14 and SFC15 if the data length is
more than 4 Byte.

NOTE!
After copying the WAGO type file into the Siemens directory comwin20\typdat5x, the
type file is registered by the program via the menu item ‘read in type file’.
After allocation of the station address, configure Wincom by selecting others on the
software menu. “Others” corresponds to the utilization of the WAGO product 750-301.

In order to integrate the I/O functions, only one configuration must be utilized. When
selecting the function CONFIGURATION the following menu appears:
Ill. 12: Configuration Menu screen
As described earlier, the stacking of the byte data stream is started by channel (0) which
must be analog I/O first from left to right of the bus coupler.
ATTENTION!
With the present Buscoupler firmware version the analog functions are defined as Input
and Outputs! The length and format are defined with 2 bytes. The correct configuration
can be seen in Ill. 12. Table 3, section 4 conforms to these requirements.
Once the analog functions and modules have been selected and configured the DI/DO
modules can be configured. The order of whether DI or DO comes first is not critical.
The placement of digitial I/O and contruction of the serial data byte stream correlates to
directly to I/O physical placement.

The existing Mastercards IM308B and CP5431 have been replaced by a new master type
IM308C. This type will compensate for the limitations of the Input/Output-addressing.
Up to now the IM308B is very common, so the configuration of this master is shown on
the following pages.
The first step is to copy the type-file from the WAGO-Disc (find this enclosed in the
Buscoupler) into the directory ....\COMET200. After the program is downloaded and the
requested language is chosen the screen will show the following picture:

Buscoupler startup and troubleshooting
After configuration of the master connection and electrical installation of the fieldbus
node/station, operation of the system can begin.
After power to the Buscoupler and I/O modules has been applied, the Buscoupler
verifies all internal functions, components and the communication interface by an
internal diagnostic routine. Then the function modules and the existing configuration is
determined. At the same time a hidden file is stored. It consists of an input and an
output area which is located on the fieldbus RAM of the log chip. During the power up
phase the ‘I/O ERR’ LED flashes with an increased frequency. After a faultless power
up the fieldbus coupler enters the state ‘fieldbus start’. The green LED ‘RUN’ indicates
that the Bus is operating normally.
In case of a fault the red ‘I/O ERR’ LED will continue flashing.
By counting the number and frequency of flashes the fault can be easily identified
quickly and accurately. A varying number of flashes and frequencies defines the fault.
The table below describes the fault condition based on the counted number of ‘I/O
ERR’ LED flashes.

Table 5: Diagnosis LEDs - on modules
After elimination of the fault, the Buscoupler can only be set to the normal working
condition by another POWER ON sequence.
The green I/O LED flashes when accessing the I/O modules internal data channels.
After being switched on, the Buscoupler queries the configuration of the bus modules
but does not carry out a data exchange with the I/O modules. This means that the red
I/O LED will extinguish after a faultless startup. The green I/O LED will indicate when
data is being exchanged by the Profibus network.
Further diagnostic functions are supplied by PROFIBUS DP:
Type of diagnostic
station related
module related
channel related
Messages concerning the general operational mode of a station such as
overtemperature or undervoltage
These messages indicate that within a defined I/O module, diagnostics are
available.
These messages indicate the cause of the fault related to an individual
Input/Output (channel), such as short-circuit at Output 2.

The fieldbus LEDs show the operating conditions of the fieldbuses. The functions of
PROFIBUS are indicated by the LEDs ‘RUN’, ‘BF’, and ‘DIA’. The fourth LED

If the LED ‘BF’ does not flash after calling the response monitoring, the cause may be a
paramatarization or diagnostic fault.
If there are only digital inputs connected to buscoupler 750-323 you have to make sure
that via the user parameter „process image actualization free-running“ (byte 16, bit 6=1)

Power supply
If non-stabilized power supply is used for the supply of the buscoupler, it must be
stabilized by a capacity ( 200 µF per 1 A load current).
For the :$*2Ç,2Ç6<67(0a filter module has been developed (288-824).
This module serves as a filter module for non-stabilized 24 V DC power supplies if the
specified voltage deviation is not met.
Reasons for the deviations may be voltage jumps in the primary circuit, overloads in the
secondary circuit or the switching of undampened inductances and capacitances.

Certificates
The modules of :$*2Ç,2Ç6<67(0 have passed the conformance test of UL.
Look for listing mark on product.
The Profibus coupler 750-301 and 750-303 are certified of PNO with Z00241 and
Z00242.
The Interbus coupler 750-304 has passed the relevant tests in accordance with the
Interbus conformance requirements (number 111).

Digital Inputs (24 V AC/DC, 120 V AC, 230 V AC, 48 V DC)
PN: 750-400...415
Technical description
The supply is applied by a series-connected termination to each I/O module for the
respective operating voltage. Power connections are made automatically from module to
module when snapped onto the DIN rail.
Attention:
The lowest power jumper contact is not carried out for some modules (e.g. 4-channel)!
A module which needs all contacts (e.g. 2 channel digital) may not be connected to the
right hand side of modules which do not have 3 power jumper contacts (e.g. 4 channel
modules).
All 2-channel digital inputs are 4-conductor devices allowing the direct connection of 4conductor sensors with the terminations V+, 0V, ground and signal.
The 4-channel digital inputs are suitable for the direct connection of two 3-conductor
sensors (V+, 0V, signal). The power distribution module 750-614 is available for the
connection of more sensors to V+ and 0V.
The modules 750-408 and 750-409 are low-side switching.
A 2-wire proximity switch can be connected to the modules 750-410 and 750-411.
RC filters are series-connected to the 5, 24 and 48 V versions for noise rejection and
switch debouncing. They are available with time constants of 3.0 ms and 0.2 ms.
The standard numerical assignment for bus operations is from left to right, starting with
the LSB. The positions of the different I/O modules in the configured node/station are
selectable by the user. A block type configuration is not necessary.
The Input module can be connected to all buscouplers of the WAGOÇI/OÇSYSTEM.

Organization of the in- and output data:
The counter begins processing with pulses at the CLOCK input. The changes from 0 V
to 24 V are counted.
The counter counts up, if the input U/D is set at 24 V. With an open circuit input or 0 V
the counter counts backwards.
The two bottom contacts each include another output. These outputs are activated
through bits in the control byte.

With the control and status-byte the following tasks are possible:
Set the counter: Put Bit 5 into the control byte. The counter with the 32 bit value is
loaded into output bytes 0-3. As long as the bits are set, the counter can stop and
information is stored. The ensuing data of the counter will be conveyed to the status
byte.
Blocking the counter: Bit 4 is set into the control byte, then the count process is
suppressed. Bit 4 in the status byte communicates the suppression of the counter.
Set the outputs: Bits 2 and 3 set the additional two outputs of the counter module.
The result of the counter is in binary.

(carry over the control-byte and the new counter position),
-wait until the input value is 0X1X.XXXX, 0x00, 0x00, 0x00, 0x00
(the status-byte shows the loading feedback) ,
-carry over 0x00, 0x00, 0x00, 0x00, 0x00 as output value (release counter).
Wait for the first and further counting pulse
-the input value is XX00.XXXX, 0x00, 0x00, 0x00, 0x00 (no counting pulse received)
-the input value is XX00.XXXX, 0x00, 0x00, 0x00, 0x01 (1 counting pulse received)
-the input value is XX00.XXXX, 0x00, 0x00, 0x00, 0x02 (2 counting pulses received)

is reached)
-the input value is XX00.XXXX, 0x00, 0x00, 0x00, 0x00 (a further counting pulse
causes an overflow)
-the input value is XX00.XXXX, 0x00, 0x00, 0x00 0x01, (a further counting pulse is
received)

The time span is predefined as 10 s. The state of the counter is stored in the processs
image until the next period. After the recording the counting starts again at 0.
The activation of the counting and the synchronisation with the SPS is made by a

Technical Description
The counter module 750-404/000-003 measures the period of the 24 V DC input signal
at the CLOCK terminal and converts it into a corresponding frequency value. The
measurement is enabled if the GATE terminal is an open circuit input or 0V. To disable
processing, the GATE input is to be set to 24 V DC.
The terminals O1 and O2 work as binary outputs. Each output can be activated via
specific bits in the CONTROL byte.
The high states of the input and output channels are each indicated by a LED.
To recognize low frequency or near zero frequency signals, the maximum time between
two data updates is parameterizable.

Functional description
The counter module acquires the time between one or more rising edges of the CLOCK
input signal and calculates the frequency of the applied signal.
The calculation and process image update are initiated every 1st, every 4th or every 16th
rising edge depending on the integration time selected via the CONTROL byte. The first
detection of a rising edge starts the cyclic period measurement and cannot provide a
valid frequency value. In this case the module will send 0xFFFFFFFFH for input
information. The same input value is returned when a static high or static low signal is
applied to the CLOCK input.
If there are no signal changes seen at the CLOCK input, the module can be forced to
update the process image after defined parameterizable time spans. In this state the
module will send the non valid value 0xFFFFFFFFH too.
The following figures illustrate a process data cycle.

Structure of Input and Output data
The input data contain the CLOCK frequency as a binary value. The representation
depends on the RANGE_SEL bits in the CONTROL byte. Even the method of
measuring is selected via these bits. The following table illustrates the different modes.

Attention:
When a new frequency range is requested, the application has to wait for valid data until
the RANGE_SEL ACK bits contain the new frequency range. The maximum delay can
be calculated using the following formula
TDmax= 2 *
number of periods to be integrated
actual frequency
If the gate is enabled the input data contains the last valid frequency value. In this state
the application cannot request a new range.
The valid frequency range stretches from 0.1 Hz (100D) up to
10 kHz (100000D).
To recognize static CLOCK signals, a watchdog timer is implemented. The default
value for the timer is 10s. The timer resets on every Power On.
The application is able to change the watchdog time during operation by using the
CONTROL byte.
This can be initiated by writing the corresponding value into the output bytes
OUTPUT_DATA 1 and OUTPUT_DATA 0 before setting the TVD REQ bit in the
CONTROL byte.
The success of the parameter transfer is acknowledged by the module via the TVD ACK
bit in the STATUS information.
Attention:
The range of the watchdog timer stretches from 0 to 16383ms (0x0000H to 0x3FFFH) in
steps of 1ms per digit.
Values which raise the permitted range of the watchdog timer are masked with 0x3FFF.
If the maximum possible frequency of the different ranges is raised (see the table with
maximum frequency ratings), the module will return the non valid data 0xFFFFFFFFH.

Digital Outputs (Standard)
PN 750-501...504, 516, 519
Technical description:
The power supply is provided by a series-connected supply module for the respective
operating voltage. Power connections are made automatically from module to module
via the internal P.J.C.s when snapped onto the DIN rail.
Attention:
The lowest power jumper contact is not carried out for some modules (e.g. 4-channel)!
A module which needs all contacts (e.g. 2 channel digital) may not be connected to the
right hand side of modules which do not have 3 power jumper contacts (e.g. 4 channel
modules).
For the digital outputs (without diagnostic) four-conductor devices (V+; 0 V; signal;
ground) are standard. In case of 12 mm wide 4-channel digital output modules it is not
possible to use 4-conductor devices. 4 signal outputs, 2xV+ and 2x0V are provided.
All digital outputs are short-circuit protected.
In case of overloads a supply module with fuse (750-601) must be connected on the
line side to protect the output modules.
The module 750-516 is low-side switching. The indicated output values have been
determined for 100% duty cycle. However, in case of the 2 A versions it is possible to
operate single channels at higher load currents, however always verify that the total
current does not exceed 3.5 A per module. Example: 2x2A (standard); 1x3.0A; 1x0.5A
(total current: 3.5 A) The standard numerical assignment for bus operations is from left
to right, starting with the LSB. The positions of the different I/O modules in the
configured node/station are selectable by the user. A block type configuration is not
necessary.The Output module can be connected to all buscouplers of the
WAGOÇI/OÇSYSTEM.

Technical description:
The power supply is provided by a series-connected supply module for the respective
operating voltage. Power connections are made automatically from module to module
via the internal P.J.C.s when snapped onto the DIN rail.
Attention:
The lowest power jumper contact is not carried out for some modules (e.g. 4-channel)!
A module which needs all contacts (e.g. 2 channel digital) may not be connected to the
right hand side of modules which do not have 3 power jumper contacts (e.g. 4 channel
modules).
Using the digital outputs with diagnostic bit outputs (750-506) allows verification of the
I/O channel by the connected bus. Example: a short-circuit at the output or an open
circuit will set the appropriate error bit true indicating I/O failure. In this configuration
the function module includes 2 digital outputs and 2 separate digital inputs. For the
digital outputs with diagnostic four-conductor devices (V+; 0V; signal; ground) are
standard. All digital outputs are short-circuit protected.
In case of overloads a supply module with fuse (750-601) must be connected on the
line side to protect the output modules.
The standard numerical assignment for bus operations is from left to right, starting with
the LSB. The positions of the different I/O modules in the configured node/station are
selectable by the user. A block type configuration is not necessary. When using I/O
modules with diagnostics, the existing inputs must be considered accordingly in the
configuration of the Node/station. The Output module can be connected to all

Digital Outputs (Solid State Relay)
PN 750-509
Technical Description
The power supply for the solid state relay module is connected by a series-connected
supply module for the respective operating voltage of 230 V. Power connections are
made automatically from module to module via the internal P.J.C.s when snapped onto
the DIN rail.
Attention:
The lowest power jumper contact is not carried out for some modules (e.g. 4-channel)!
A module which needs all contacts (e.g. 2 channel digital) may not be connected to the
right hand side of modules which do not have 3 power jumper contacts (e.g. 4 channel
modules).
The power supply of the control side is not made via the power jumper contacts but
directly from the electronics. The respective output contacts of the switching element
are therefore always positioned at the field side. One termination point of these contacts
must be directly connected to the power supply. For the digital outputs four-conductor
devices (V+; 0V; signal; ground) are standard. All digital outputs are short-circuit
protected. In case of overloads a supply module with fuse (750-609) must be
connected on the line side to protect the output modules.
The standard numerical assignment for Bus operation is from left to right, starting with
the LSB. The positions of the different inputs in the configured station are via the user’s
choice. A block type assembly is not necessary. The Output module can be connected to

Pulsewidth Module
PN 750-511
Technical Description:
This description is for hard and software version X X X X 2 B 0 2- - - - . The part
number is displayed on the right side of the module.
The initial pre-programmed base frequency is for 250 Hz. The resolution is 10 Bits and
the pulsewidth is modulated.
Attention:
The lowest power jumper contact is not carried out for some modules (e.g. 4-channel)!
A module which needs all contacts (e.g. 2 channel digital) may not be connected to the
right hand side of modules which do not have 3 power jumper contacts (e.g. 4 channel
modules).
The following description is preliminary and is applicable to the factory configuration.
The pulsewidth output module 750-511 produces a binary modulated signal of 24 V.
The connection of the consuming device should be made via the „O“ and 0 V (common)
contacts of the module. The distribution of the 24 V DC is made via the power jumper
contacts. If galvanic isolation is desired, a new power feed via a 750-602 is required.
The PWM module can be connected to all buscouplers of the WAGOÇI/OÇSYSTEM
(except for the economy type).

The function module 750-461 allows the direct connection of PT- or Ni-resistance
sensors. The module is suitable for 2- or 3-wire RTDs. Connection is made according to
the above wiring diagram.
Linearization is accomplished over the entire measurement range by a microprocessor.
The temperature ranges of the above listed RTD types is available to the user. The
temperature ranges of the sensors are represented with a resolution of 1 bit per 0.1° C in
one word (16 bits). Resulting from this, 0°C corresponds to the hexadecimal value 0000
and 100°C is 03E8 (dez.1000). Temperatures below 0° are represented in two’s
complement with a leading ‘1’.
The function module works in the defined temperature range for the PT100 sensors of
-200°C to +850°C. The voltage resolution is represented with 16 bits. An A/D
converter and processor converts the voltage value to a numerical value proportional to
the temperature of the selected resistance temperature sensor.
A short circuit or an interruption of the RTD wire is transmitted to the bus module and
indicated by the red error LED. The green LED identifies that the module is
communicating properly with the connected Buscoupler.

The function module 750-462 permits the direct connection of thermocouple sensors.
The module is suitable for 2 or 3-wire thermocouples. For the 2-wire connection
technique, connect the thermocouple wires between TC- and TC+ . For the 3-conductor
technique the shield is also connected. The operation of grounded sensors is provided by
means of internal electrical isolation.
The function module 750-469 alos detects a broken wire. You can find the PNs for the
different sensor types for 750-462 in the following table.
Warning: Both inputs are referenced to a common potential (not isolated)!
The linearization is provided over the complete range by a microprocessor. The
temperature ranges of the sensors are represented with a resolution of 1 bit per 0.1°C in
one word (16 Bit). Thus, 0°C corresponds to the value 0000, and 25.5°C correspond to
the value 0 x 00FF. Temperatures below 0°C are represented in two’s complement with
a leading ‘1’.
Within the whole range of all thermocouples, the function module works like a ‘µV
meter’. The voltage resolution is represented with 16 bits. A processor converts the
voltage value into a numerical value proportional to the measured temperature of the
selected type of thermocouple.
In order to compensate the offset voltage at the clamping point, a cold junction
thermocouple compensation calculation is carried out. The circuit contains a
temperature measuring sensor at the ‘CAGE CLAMP’ connection and considers the
temperature offset voltage when calculating the measured value.

The numerical formats
All temperature values are represented in a uniform numerical format. In the default
setting (type K) one Bit corresponds to 0.1°C. The output value corresponds to the
temperature range of each sensor as defined according to standards. By using a
configuration tool, the output formats can be chosen. The linearization can be switched

Technical Description
This description is only intended for hardware version X X X X 2 A 0 1 - - - -. The
serial number can be found on the right side of the module.
The input channels are single ended and they have a common ground potential.
The inputs are connected to +I. Via 24 V / 0 V a sensor can be provided directly from
the module. Power connections are made automatically from module to module when
snapped onto the DIN rail.
The shield is connected to „S“. The connection is made automatically when snapped
onto the DIN rail.
Attention:
The lowest power jumper contact is not carried out for some modules (e.g. 4-channel)!
A module which needs all contacts (e.g. 2 channel digital) may not be connected to the
right hand side of modules which do not have 3 power jumper contacts (e.g. 4 channel
modules).

Supply modules
PN750-601, 602, 609, 610, 611, 612, 613, 615
Technical Description
The supply module provides I/O module power through the power jumper contacts.
Maximum current supply to all connected modules is 10 A. Maximum current supply to
the modules with fuse holder is 6.3 A. Should higher currents be necessary, intermediate
supply modules may be added in the assembly.
The modules 750-601, 609, 615, 610 and 611 are additionally equipped with a fuse
holder. The change of the fuse is very easy by drawing out the fuse holder and changing
the fuse. A blown fuse is indicated by a LED.
The modules 750-610 and 611 send information about the status of the supply module
to the fieldbus coupler through two input bits.

The use of this module in conjunction with a SSI encoder provides direct positional
information rather than the type of data resultant from incremental type encoders.
Absolute encoders are comprised of several data disks which generate a data
word which is unique through out the 360 degrees of rotation. The data format
is a modified binary pattern in either Graycode or Dualcode.
The resolution of the sensor depends upon the configuration of the sensor and
the physical number of revolutions in the motion profile. Since the basis of the
encoder is to provide absolute positional information based upon a mechanical
configuration limited to one revolution or less. The maximum resolution of this
module is 24 bit.
The frequency of the data signal input to the SSI module is maintained at 125 kHz.

Operational Characteristics:
The quadrature encoder interface accepts up to two input signals for the counting
increment. The index pulse may also be considered should the control configuration
require. There is also a Latch and Gate input available on the module for added
functionality.
The quadrature encoder provides two signals that are shifted 90 degrees from each
other, signals A and B. In order to achieve a better common mode noise rejection ratio,
the output signals from the encoder are transmitted via a differential signal. Their
complement signals, A(inv.) and B(inv.) are also transmitted. A directional
determination may be made by which signal leads. If the A signal leads, the direction is
considered to be forward. If the B signal leads, the direction is considered to be reverse.
By exchanging the A and A(inv.) the phase relationship will be changed by 180 degrees,
thus allowing the direction to be preset via the wiring configuration.
Most quadrature encoders have an Index signal, or Z rev, as well as the incremental
signal. This signal provides one pulse per revolution with a duration equal to an
incremental pulse.
The inputs to the quadrature encoder module must be supplied from an encoder with
Line Driver Outputs for proper operation. The 5 Volt DC output may be used to power
the encoder. The 24 Volt DC input supply must be provided from an external power
supply.
The Gate and Latch inputs are 24 Volt DC.

It is possible to process and/or check the below listed actions via the control and status
bits.
Extending the 16 bit counting range: The internal counting range is 16 bits or a
maximum value of 65535. Should the application require an extended count range the
location-difference-integration method may be employed. This method uses the control
system to store the interrogated counter value. Any new interrogated value will have the
previously stored counter value subtracted from it. This value will then be added to an
accumulated register value. It is assumed that the counter difference of the two
interrogated values is smaller than 16 bits therefore overflows need not be considered.
Another method calculates the extended counter range via the underflow and overflow
status bits. The interrogated value is either added or subtracted to the accumulation
register depending upon the status of the overflow or underflow bits.
Set Counter Position: The presetting of the counter is possible via the CNT_SET bit.
The desired preset is loaded into the data register and the CNT_SET bit is set from 0 to
1. The CNTSET_ACC bit will be set to 1 when the preset value is loaded into the count
register.
Maintaining the Present Counter Position: The counter present value may be
maintained or latched via the external Latch input. First the external latch must be
enabled via the EN_LATEXT bit. Once the input is enabled, the data will be latched
into the counter module upon a 0 to 1 transition. Upon completion of the latch process
the external latch valid bit LATEXT_VAL will be set to 1.
Maintaining a Reference Point: The storage of a present counter value may also
accomplished via the Index pulse from the encoder. First the index latch enable bit must
be set, EN_LACT, to a value 1. The counter present value will be latched upon the low
to high transition of the Index input. Upon completion of the data latch process the
Index Latch Valid bit, LACT_VAL will be set to 1.

Description of RS 232:
The interface module is designed to operate with all WAGO I/O fieldbus couplers. The
serial interface module allows the connection of RS 232-Interface devices to the WAGO
I/O SYSTEM. The RS 232 Interface module can provide gateways within the fieldbus
protocol. This allows serial equipment such as printers, barcode readers, and links to
local operator interfaces to communicate directly by the fieldbus protocol with the PLC
or PC Master.
This module supports no higher level of protocol. Communication is made completely
transparent to the fieldbus allowing flexibility in further applications of the serial
interface module. The communication protocols are configured at the Master PLC or
PC.
The 128 byte input buffer provides for high rates of data transmission. When using
lower rates of transmission speed you can collect the received data, with less priority,
without loosing data.
The 16 byte output buffer provides for faster transmission of larger data strings.
FUNCTION The data transmission takes place at 9.600 baud (default value). 1 startbit, 8 databits and 1
stopbit will be transmitted. No parity is available. The user controls data via the RTS and
CTS signals. These signals are generated in the module depending on the loading status of
the buffers. These controls can be deactivated by means of an external jumper. RTS and
CTS are to be connected.
For testing purposes the Windows 3.11 terminal emulation can be used. A cable with a 9pole sub-D socket is required. Pin 5 is connected to input M. Pin 2 is connected to TxD and
Pin 3 to RxD. RTS and CTS of the module are connected. A hardwarehandshake between
terminal emulation and SPS is not possible though.

Structure of input and output data:
The module is a combined analog input and output module with 2 x 16 bit input and
output data. The transfer of the data to be transmitted and the received data is made via
up to 3 output and 3 input bytes. One control byte and one status byte are used to control
the floating data.
Requests are indicated by a change of a bit. An assigned bit indicates execution by
adopting the value of the request bit.
Up to 3 characters which have been received via interface can be stored in the input
bytes 0 to 2. The output bytes will contain the characters to be sent.
The control byte consists of the following bits:

Description of data exchange module
The data exchange module allows the exchange of 4 (5) bytes between different fieldbus
systems via multiplexing of a serial connection. The delay which is caused by the
multiplexor is < 5ms. The integrated watchdog function switches all outputs to zero if
there is no valid information for more than 200 ms via the multiplex connection.
The 128 bytes input buffer provides for high rates of data transmission. When using
lower rates of transmission speed you can collect the received data, with less priority,
without loosing data.
The 16 byte output buffer provides for faster transmission of larger data strings.
The data exchange module is connected peer-to-peer. For the wiring of the serial
multiplex connection the RxD and TxD cables are crossed. The following illustrations
show the peer-to-peer connection and the internal structure of the data exchange
module.

Structure of input and output data:
The module is a combined special function input and output module with 1 x 32 (40) Bit
input and output data. The tranfer of the data to be transmitted and the received data is
made via up to 5 input and 5 output Bytes. One control byte and one status byte are used
to control the floating data.

a frame.
The PLC is able to control transmission and reception of data by means of the control
byte and the status byte.
Control of the multiplex connection: In the process image of the transmitting
buscoupler one Bit is set to „1“ for the whole time. As long as this Bit is „1“ in the
receiving coupler, further input Bits can be evaluated. If the Bit is „0“ the multiplex
connection has been disrupted. The further Bits are also 0 because of the watchdog.
Control of the multiplex connection with acknowledge: If the transmitting
buscoupler gets an acknowledge from the receiving buscoupler, the received bit must be
transfered as an output bit to the process image. The transmission is successful as long
as the Bit is „1“.
Handshake: If a serial data exchange should be made with the data exchange module,
the handshake can be made via „Toggle Bits“. Therefore an input bit and an output bit
are reserved. As soon as those bits are different from each other, a request from the
opposite module is made. As soon as the request is executed the output bit is toggled.

Application in Explosive Environments
Foreword
• 1
Ex-1 Application in Explosive Environments
Ex-1.1 Foreword
Today’s development shows that many chemical and petrochemical
companies have production plants, production, and process automation
machines in operation which use gas-air, vapor-air and dust-air mixtures
which can be explosive. For this reason, the electrical components used in
such plants and systems must not pose a risk of explosion resulting in injury to
persons or damage to property. This is backed by law, directives or
regulations, on a national and international scale. WAGO-I/O-SYSTEM 750
(electrical components) is designed for use in zone 2 explosive environments.
The following basic explosion protection related terms have been defined.
Ex-1.2 Protective measures
Primarily, explosion protection describes how to prevent the formation of an
explosive atmosphere. For instance by avoiding the use of combustible
liquids, reducing the concentration levels, ventilation measures, to name but a
few. But there are a large number of applications, which do not allow the
implementation of primary protection measures. In such cases, the secondary
explosion protection comes into play. Following is a detailed description of
such secondary measures.
Ex-1.3 Classification meeting CENELEC and IEC
The specifications outlined here are valid for use in Europe and are based on
the following standards: EN50... of CENELEC (European Committee for
Electrotechnical Standardisation). On an international scale, these are reflected
by the IEC 60079-... standards of the IEC (International Electrotechnical
Commission).
Ex-1.3.1
Divisions
Explosive environments are areas in which the atmosphere can potentially
become explosive. The term explosive means a special mixture of ignitable
substances existing in the form of air-borne gases, fumes, mist or dust under
atmospheric conditions which, when heated beyond a tolerable temperature or
subjected to an electric arc or sparks, can produce explosions. Explosive zones
have been created to describe the concentrations level of an explosive
atmosphere. This division based on the probability of an explosion occurring
is of great importance both for technical safety and feasibility reasons,
knowing that the demands placed on electrical components permanently
employed in an explosive environment have to be much more stringent than
those placed on electrical components that are only rarely and, if at all, for
short periods, subject to a dangerous explosive environment.
WAGO-I/O-SYSTEM 750
Modular I/O-System
2 •
Application in Explosive Environments
Classification meeting CENELEC and IEC
Explosive areas resulting from gases, fumes or mist:
• Zone 0 areas are subject to an explosive atmosphere
(> 1000 h /year) continuously or for extended periods.
• Zone 1 areas can expect the occasional occurrence of an explosive
atmosphere (> 10 h ≤ 1000 h /year).
• Zone 2 areas can expect the rare or short-term occurrence of an explosive
atmosphere (> 0 h ≤ 10 h /year).
Explosive areas subject to air-borne dust:
• Zone 20 areas are subject to an explosive atmosphere
(> 1000 h /year) continuously or for extended periods.
• Zone 21 areas can expect the occasional occurrence of an explosive
atmosphere (> 10 h ≤ 1000 h /year).
• Zone 22 areas can expect the rare or short-term occurrence of an explosive
atmosphere (> 0 h ≤ 10 h /year).
Ex-1.3.2
Explosion protection group
In addition, the electrical components for explosive areas are subdivided into
two groups:
Group I:
Group I includes electrical components for use in fire-damp
endangered mine structures.
Group II:
Group II includes electrical components for use in all other
explosive environments. The group is further subdivided by
pertinent combustible gases in the environment.
Subdivision IIA, IIB and IIC takes into account that
different materials/substances/gases have various ignition
energy characteristic values. For this reason the three subgroups are assigned representative types of gases:
•
•
•
IIA – Propane

Temperature classes
The maximum surface temperature for electrical components of explosion
protection group I is 150 °C (danger due to coal dust deposits) or 450 °C (if
there is no danger of coal dust deposit).
In line with the maximum surface temperature for all ignition protection types,
the electrical components are subdivided into temperature classes, as far as
electrical components of explosion protection group II are concerned. Here the
temperatures refer to a surrounding temperature of 40 °C for operation and
testing of the electrical components. The lowest ignition temperature of the
existing explosive atmosphere must be higher than the maximum surface
temperature.

for zone 2 (see below)
Zone 2
Ignition protection “n“ describes exclusively the use of explosion protected
electrical components in zone 2. This zone encompasses areas where
explosive atmospheres can only be expected to occur rarely or short-term. It
represents the transition between the area of zone 1, which requires an
explosion protection and safe area in which for instance welding is allowed at
any time.
Regulations covering these electrical components are being prepared on a
world-wide scale. The standard EN 50 021 allows electrical component
manufacturers to obtain certificates from the corresponding authorities for
instance KEMA in the Netherlands or the PTB in Germany, certifying that the
tested components meet the above mentioned standards draft.
Type “n” ignition protection additionally requires electrical components to be
marked , with the following extended identification:
• A – non spark generating (function modules without relay /without
switches)
• AC – spark generating, contacts protected by seals (function modules with
relays / without switches)
• L – limited energy (function modules with switch)

Divisions
The "Divisions" describe the degree of probability of whatever type of
dangerous situation occurring. Here the following assignments apply:
Explosion endangered areas due to combustible gases, fumes, mist and dust:
Ex-1.4.2
Division 1
encompasses areas in which explosive atmospheres are to be expected
occasionally (> 10 h ≤ 1000 h /year) as well as continuously and long-term
(> 1000 h /year).
Division 2
encompasses areas in which explosive atmospheres can be expected rarely
and short-term (>0 h ≤ 10 h /year).
Explosion protection groups
Electrical components for explosion endangered areas are subdivided in three
danger categories:
Class I (gases and fumes):
Group A (Acetylene)
Group B (Hydrogen)
Group C (Ethylene)
Group D (Methane)
Class II (dust):
Group E (Metal dust)
Group F (Coal dust)
Group G (Flour, starch and cereal dust)
