2.3
What are fail-safe automation systems and fail-safe modules?
Fail-safe automation systems
Fail-safe automation systems (F-systems) are used in systems with higher safety requirements. F-systems control processes and ensure that they are in a safe state immediately after shutdown. In other words, F-systems control processes in which an immediate shutdown does not endanger persons or the environment.
Safety Integrated
Safety Integrated is the integrated safety concept for automation and drive technology from
Siemens.
Proven technologies and systems from automation technology, such as the S7-1500 automation system described here, are used for safety engineering. Safety Integrated includes the complete safety sequence, ranging from sensor, actuator and fail-safe modules right through to the controller, including safety-related communication via standard fieldbuses. Drives and controllers handle safety tasks in addition to their actual functions.
Fail-safe modules
Fail-safe modules (F-modules) differ from non-fail-safe modules in that they internally monitor themselves and their sensor and actuator lines for faults and enter the safe state when faults are detected.
The F-CPU communicates with a fail-safe module via the safety-related PROFIsafe bus profile.
Application area of S7-1500/ET 200MP with fail-safe I/O modules
By using S7-1500 automation systems / ET 200MP distributed I/O systems with fail-safe
I/O modules, you replace the conventional safety engineering technical setup. This includes replacing, for example, switching devices for emergency stop, protective door monitors, two-hand operation, etc.

SIMATIC Safety F-system with S7-1500 and ET 200MP
The figure below contains an example of an F-system SIMATIC Safety with S7-1500,
ET 200MP and PROFINET IO.
Fail-safe I/O modules and non-fail-safe I/O modules can be combined in an
S7-1500/ET 200MP configuration.
The fail-safe IO controller (F-CPU) exchanges safety-related data with fail-safe modules. It does not exchange safety-related data with non-fail-safe modules.
Figure 2-6 Fail-safe automation system SIMATIC Safety (example)
Fail-safe I/O modules S7-1500/ET 200MP
The following fail-safe I/O modules are available for S7-1500/ET 200MP:
● Fail-safe digital input modules detect the signal states of safety-related sensors and send the relevant safety frames to the F-CPU.
● Fail-safe digital output modules are used to control actuators for safety-oriented tasks.

Introduction
Hardware configuration
The S7-1500 automation system/ET 200MP distributed I/O system consists of a single-row configuration in which all modules are installed on one mounting rail. The modules are connected by means of U connectors, and thus form a self-assembling backplane bus.
You can configure the S7-1500 automation system/ET 200MP distributed I/O system with fail-safe and non-fail-safe modules.
3.1.1
Hardware configuration of the S7-1500 automation system
Maximum configuration
● The integrated system power supply of the CPU supplies 10 W or 12 W (depending on
CPU type) to the backplane bus. The power budget calculation determines the exact number of modules (without optional PS) that can be operated with the CPU. The
operating principle is described in section Power balance calculation (Page 45).
● A maximum of three system power supplies (PS) is possible: one can be inserted to the left of the CPU and two can be inserted to the right of the CPU.
● If you insert a system power supply (PS) to the left of the CPU, this yields a possible maximum configuration of a total of 32 modules, which occupy slots 0 to 31. If system power supplies (PS) are needed to the right of the CPU, they each occupy one slot.

System and load power supply
Types of power supplies
The S7-1500 automation system/ET 200MP distributed I/O system distinguishes between two types of power supply:
● System power supply (PS)
● Load current supply (PM)
System power supply (PS)
The system power supply has a connection to the backplane bus (U connector) and supplies solely the internally required system voltage. This system voltage supplies parts of the module electronics and the LEDs. A system power supply can also supply CPUs or interface modules if these are not connected to a 24 VDC load current supply.
Load current supply (PM)
The load current supply feeds the input/output circuits of the modules, as well as the sensors and actuators of the plant, if installed. The supply of the CPU/interface module with 24 V DC is optional if you supply the voltage for the backplane bus via a system power supply.
Special characteristic of the load current supply
Load current supplies are mounted on the "S7-1500 mounting rail" and do not have a connection to the backplane bus.

Optionally, you can insert up to two system power supplies (PS) in the slots to the right of the
CPU/interface module.
The number of load current supplies is unlimited.
Observe the installation rules and specified installation distances in the manuals of the load current supplies.

● PS 60W 24/48/60V DC: Supply voltage with 24/48/60 V DC and infeed power to the backplane bus of 60 W
● PS 60W 120/230V AC/DC: Supply voltage with 120/230 V AC and infeed power to the backplane bus of 60 W
Load current supplies
The load current supplies listed below have been technically adapted especially to the
S7-1500 automation system/ET 200MP distributed I/O system. Use of the listed load current supplies is not imperative because a SITOP module, for example, can be used an alternative.
● PM 70W 120/230 V AC: Supply voltage with 120/230 V AC and infeed power to the backplane bus of 70 W
● PM 190W 120/230 V AC: Supply voltage with 120/230 V AC and infeed power to the backplane bus of 190 W

3.2 System and load power supply
3.2.1
Introduction
Use of system power supplies
If the power fed from the CPU/interface module into the backplane bus is not sufficient to supply all connected modules with power, system power supplies (PS) are required.
Whether or not you need a system power supply depends on the power consumption of the modules used. The power supplied by the CPU/interface module and the system power supplies must be greater than the power required by the I/O modules.
During configuration, STEP 7 compares the supplied power and the power required by the modules. If the required power is too high, you receive a corresponding message from
STEP 7.
Slots for system power supplies
The following slots may be used for system power supplies:
● A system power supply in slot 0 to the left of the CPU/interface module
● Up to 2 system power supplies in the slots to the right of the CPU/interface module
(power segments) A power segment consists of a power supply module and the modules supplied by it.
Power segment
If you are using system power supplies to the right of the CPU/interface module, divide the configuration into power segments.
Configuration variant with power segments

If you use the TIA Portal for configuring, it automatically checks the configuration for consistency and informs you as of which module you must open up a new power segment.

Additional information on the performance values (power feed, power consumption) of the
CPU, interface module, system power supply, and I/O modules can be found in the manuals
( http://support.automation.siemens.com/WW/view/en/57251228 ) of the respective modules.
3.2.2
Special considerations for the use of a system power supply in the first power segment
Infeed options
There are three options for the infeed of the required system voltage in the backplane bus:
● Infeed via CPU/interface module
● Infeed via CPU/interface module and system power supply
● Infeed only via system power supply in slot 0
Infeed via CPU/interface module
Infeed via the CPU/interface module generally suffices for small and medium hardware configurations. The power consumption of the connected modules must not exceed the power supplied by the CPU/interface module.
In this configuration variant, supply the CPU/interface module with 24 V DC from a load current supply.
Procedure
To set up the supply by means of the CPU/interface module, follow these steps:
1.
Open the "Properties" tab of the CPU/interface module in STEP 7 and select the "System power supply" in the navigation.
2.
Select the option "Connection to supply voltage L+".

Application planning
3.2 System and load power supply
Infeed via CPU/interface module and system power supply
For larger hardware configurations, infeed into the backplane bus by the CPU/interface module alone no longer suffices. If the modules consume more power in total than the power supplied by the CPU/interface module, you must insert an additional system power supply.
Supply the system power supply with the permissible supply voltage and the CPU/interface module with 24 V DC.
Both the system power supply and the CPU/interface module feed current into the backplane bus. The supplied power is summed.
Power addition: "Infeed power of the system power supply" + "Infeed power of the
CPU/interface module"
Procedure
To set up the supply by means of the CPU/interface module and system power supply, follow these steps:
1.
Open the "Properties" tab of the CPU/interface module in STEP 7 and select the "System power supply" in the navigation.
2.
Select the option "Connection to supply voltage L+".
Figure 3-7 Supply voltage via the CPU/interface module and system power supply
Infeed via system power supply only
As a further possibility you can supply the required power to the backplane bus using only a system power supply (in slot 0). In this case, the CPU/interface module is not supplied with
24 V DC, and draws its supply from the backplane bus. The system power supply must be inserted to the left of the CPU/interface module for this.
In general, you can use system power supplies with AC or DC infeed for the configuration.
If no supply voltage with 24 V DC is present (and e.g. only CMs/CPs are inserted next to the
CPU), you can use a system power supply with 230 V AC because the CMs/CPs are supplied via the backplane bus.

Introduction
Use of load power supplies
The system power supply (PS), central modules (CPU), interface module and input and output circuits of the I/O modules are supplied with 24 V DC by the load current supply (PM).
Load current supplies can be mounted on the mounting rail but do not have a connection to the backplane bus.
Observe the installation rules and specified installation distances in the manuals of the load current supplies.
Use of multiple load current supplies
Several load current supplies (PM) can be used as follows for higher output currents:
Every load current supply feeds independent 24 V DC load lines.
Alternatively you can use an external 24 V power supply, e.g. from the SITOP line.

If safe galvanic isolation (SELV/PELV according to IEC 60364-4-41) is ensured, you can supply the modules alternatively with 24 V DC from the control cabinet.

3.4 Power balance calculation

Power balance calculation
Principle of power balance calculation
In order to ensure that modules are supplied from the backplane bus, the fed-in power is compared with the power required by the modules. The power balance calculation checks whether the power provided by the system power supplies including CPU/interface module is greater than or equal to the power used by the consumers (modules).
In order to operate the configuration with its used modules, the power balance must be positive for each power segment in use.
This means that the power fed into the power segment is greater than the power consumed by the modules.
Take care even during planning, that the power fed into the backplane bus is always greater than or equivalent to the power drawn. The TIA Selection Tool
( http://w3.siemens.com/mcms/topics/en/simatic/tia-selection-tool ) aids you during planning.
The power fed into the backplane bus by the CPU/interface module and system power supply is listed in the technical specifications of the CPU/interface module in the corresponding manuals.
The power consumed from the backplane bus by an I/O module or the CPU/interface module can be found in the technical specifications in the corresponding manuals.
The power balance calculation is performed:
● When configuring with STEP 7
● During operation by the CPU

3.4 Power balance calculation
Power balance calculation when configuring with STEP 7
STEP 7 checks compliance with the power balance during the configuration.
Proceed as follows to evaluate the power balance calculation:
1.
Perform the configuration of the S7-1500/ET 200MP with all the required modules.
2.
In the network view, select the CPU/interface module or the system power supply.
3.
Open the "Properties" tab in the inspector window.
4.
Select the "System power supply" entry in the area navigation.
5.
Check the "Power segment overview" table, so see whether the power balance is positive. If the power balance is negative, the underpowered modules will be marked in red.
Figure 3-10 Example of a power balance calculation with STEP 7
Power balance calculation check for overload by the CPU/interface module
Compliance with a positive power balance is monitored by the CPU/interface module:
● At every POWER ON
● At every change of the installed hardware
Causes for overload
An overload can still occur despite a positive power balance during planning. The cause for overload can be a hardware configuration that does not correspond to the configuration in
STEP 7, for example:
● More I/O modules are inserted in the actual configuration than were planned
● A supply voltage L+ (24 V DC) that is necessary for operation is not connected when system voltage infeed via the CPU/interface module is specified during parameter
● A system power supply that is necessary for operation is not inserted
● A system power supply that is necessary for operation is not switched on (power connection plug or on/off switch)
● A system power supply that is necessary for operation has no U connector inserted

3.4 Power balance calculation
Response of the CPU to negative power balance or failure of system power supplies
As soon as a negative power balance/overload is detected by the CPU in a power segment, the following actions are executed:
● CPU stores the retentive data
● CPU enters the event in the diagnostics buffer
● CPU carries out a restart and repeats this until the cause of the negative power balance is resolved
Response of the interface module to negative power balance or failure of system power supplies
As a result of the overload, the interface module switches off all power segments. The I/O controller or DP master can no longer access the I/O modules. The interface module provides diagnostic information and periodically checks the connection to the backplane bus and re-establishes it.
Exception: In the case of a voltage drop or a hardware fault in power segment 2 or 3, the corresponding system power supply module switches off its power segment (and possibly the following segments), and generates a diagnostic alarm, if possible.

Introduction
Basics
All modules of the S7-1500 automation system/ET 200MP distributed I/O system are open equipment. This means that you may only install this system in housings, cabinets or electrical operating rooms. The housings, cabinets and electrical operating rooms must guarantee protection against electric shock and spread of fire. The requirements regarding mechanical strength must also be observed. The housings, cabinets, and electrical operating rooms must not be accessible without a key or tool. Access may only be possible for instructed or authorized personnel.
Installation position
The S7-1500 automation system/ET 200MP distributed I/O system can be used in a horizontal installation for ambient temperatures up to 60 °C and in vertical installation for ambient temperatures up to 40 °C. Additional information can be found in the section
Mechanical and climatic ambient conditions (Page 242).
Mounting rail
In addition to the S7-1500/ET 200MP modules, other components can be mounted on the mounting rail; for example, modules from the S7-1200 and ET 200SP portfolio, terminals, circuit breakers, small contactors or similar components.
These components can influence the installation dimensions for the cable duct.
Modules can be mounted up to the outer edge of the mounting rail (marginless assembly).
The mounting rails are available in various lengths. You can order the mounting rails using the online catalog or the online ordering system. You can find the available lengths and
article numbers in the Accessories/spare parts (Page 253) section.

Wiring
5.1 Rules and regulations for operation
Line voltage
Below, everything you need to consider in terms of line voltage is described (refer to section
Information on insulation tests, protection class, degree of protection and rated voltage
● For fixed plants or systems without multipole circuit breaker, a mains disconnection device (multipole) must be available in the building installation.
● For load current supplies, the configured rated voltage range must correspond to the local line voltage.
● For all power circuits of the S7-1500 automation system/ET 200MP distributed I/O system, the fluctuation/deviation of the line voltage from the rated value must be within the permitted tolerance.
24 V DC supply
The following describes what you must pay attention to in terms of the 24 V DC supply:
● Power supply units for the 24 V DC supply must have a safe galvanic isolation in accordance with IEC 60364-4-41.
● To protect the S7-1500 automation system/ET 200MP distributed I/O system from lightning and overvoltages, use overvoltage arresters.
Suitable components for the lightning and overvoltage protection are specified in the
Defining interference-free controllers
( http://support.automation.siemens.com/WW/view/en/59193566 ) function manual.
Protection against electrical shock
The mounting rail of the S7-1500 automation system/ET 200MP distributed I/O system has to be connected conductively with the protective conductor as protection against electric shock.
Protection against external electrical influences
The following describes what you must pay attention to in terms of protection against electrical influences and/or faults:
● Make sure that the system for discharging electromagnetic interference is connected to a protective conductor with sufficient diameter for all plants with an S7-1500 automation system/ ET 200MP distributed I/O system.
● For supply, signal and bus lines, you must ensure that the laying of the lines and the installation is correct.
● For signal and bus lines, you must ensure that a wire/cable breakage or a cross-wire does not lead to undefined states of the plant or system.

5.2 Additional rules and regulations for operation of the S7-1500/ET 200MP with fail-safe modules
Additional rules and regulations for operation of the
S7-1500/ET 200MP with fail-safe modules
5.2.1
Safe functional extra-low voltage (SELV) for fail-safe modules
WARNING
The fail-safe modules must be operated with safe functional extra low voltage (SELV,
PELV).
You can find more information on safe functional extra-low voltage in the data sheets, for example, of the applicable power supplies.
The fail-safe modules operate at a rated voltage of24 V DC. The tolerance range is
19.2 V DC to 28.8 V DC.
Within the overvoltage range from 32 V DC to 36 V DC, the F-modules react in a fail-safe manner and the inputs and outputs are passivated. For overvoltages greater than 36 V DC, the F-modules are permanently de-energized and can be damaged.
Use a power supply unit that does not exceed U m
= 36 V DC even in the event of a fault.
For more on this, refer to the information in the data sheet on overvoltage protection in the case of an internal error. Or implement appropriate measures to limit the voltage, e.g., use of a surge protection device.
All system components that can supply electrical energy in any form whatsoever must fulfill this condition.
Each additional circuit (24 V DC) used in the system must have a safe functional extra low voltage (SELV, PELV). Refer to the relevant data sheets or contact the manufacturer.
Sensors and actuators with an external power supply can also be connected to F-modules.
Make sure that power is supplied to these components from safe functional extra-low voltage as well. The process signal of a 24 V DC digital module may not exceed a fault voltage U m
in the event of a fault.
WARNING
Even when a fault occurs, the permissible potential difference between the supply of the interface module (bus voltage) and the load voltage must not be exceeded.
An external direct electrical connection is one way to meet this requirement. This also prevents potential differences from causing voltage additions at the individual voltage sources, which could cause the fault voltage U m
to be exceeded.

Wiring
5.2 Additional rules and regulations for operation of the S7-1500/ET 200MP with fail-safe modules
Power supply requirements in case of voltage interruptions
Note
Always use power packs or power supply units (24 VDC) with a mains buffering time of at least 20 ms to ensure adherence to IEC 61131-2.
Also take into consideration the respective requirements of your product standards regarding mains buffering time.
Information on the power supply components is available on the Internet
( https://mall.industry.siemens.com
).
5.2.2
Requirements of sensors and actuators for fail-safe modules
General requirements for sensors and actuators
Note the following important warning regarding safety-related use of sensors and actuators:
WARNING
Note that instrumentation with sensors and actuators bears a considerable safety responsibility. Also bear in mind that sensors and actuators generally do not have a service life of 20 years as defined in IEC 61508:2010 without considerable loss of safety.
The probability of hazardous faults and the rate of hazardous faults of safety functions must comply with an SIL-defined high limit. A listing of values achieved by F-modules in the technical specifications of the F-modules is available under "Fail-safe performance characteristics".
To achieve the respective safety class, suitably qualified sensors and actuators are necessary.
Additional sensor requirements
General rule: A single-channel sensor is sufficient to achieve SIL3/Cat.3/PLd. However, to achieve SIL3/Cat.3/PLd with a single-channel sensor, the sensor itself must be
SIL3/Cat.3/PLd-capable; otherwise, the sensor must be connected via two channels to achieve this safety level.
66
Automation system
System Manual, 09/2016, A5E03461182-AD
Wiring
5.2 Additional rules and regulations for operation of the S7-1500/ET 200MP with fail-safe modules
To achieve Cat.4, sensors must be connected via two channels.
WARNING
In the case of fail-safe input modules, a "0" value is output to the F-CPU after detection of faults. You therefore need to make sure that the sensors are implemented in such a way as to ensure the reliable reaction of the safety program when the sensor is in the "0" state.
Example: In its safety program, an EMERGENCY-STOP sensor must achieve the shutdown of the respective actuator when it is in the "0" state (EMERGENCY-STOP button pressed).
Duration requirements for sensor signals
WARNING
Observe the following requirements for sensor signals:
• In order to ensure the correct detection of the sensor signals via fail-safe modules with inputs, you need to make sure that the sensor signals are output for a minimum duration.
•
In order for pulses to be detected with certainty, the time between two signal changes
(pulse duration) must be greater than the PROFIsafe monitoring time.
Safe detection of inputs through F-modules
The minimum duration of sensor signals for F-modules with inputs depends on the configured input delay, the parameters of the short circuit test of the sensor supplies, and the configured discrepancy behavior for 1oo2 evaluation. The duration of the signal must be greater than the maximum response time of the configured application. Information on calculating the maximum response time can be found in section "Response times" of the respective F-module.
The maximum permitted switching frequency of the sensor signals results from the minimum duration.
Additional requirements for actuators
The fail-safe output modules test the outputs at regular intervals. The F-module briefly switches off the activated outputs and, if necessary, switches on the deactivated outputs.
You can assign the maximum duration of the test pulses (dark and light period) with parameters.
Automation system
System Manual, 09/2016, A5E03461182-AD
67
Wiring
5.2 Additional rules and regulations for operation of the S7-1500/ET 200MP with fail-safe modules
High-speed actuators may briefly drop out or be activated during this test. If your process does not tolerate this, set the pulse duration of the light or dark test correspondingly or use actuators that have sufficient lag.
WARNING
If the actuators switch voltages greater than 24 V DC (for example, 230 V DC), safe electrical isolation must be ensured between the outputs of a fail-safe output module and the components carrying a higher voltage (in accordance with EN 60664-1:2010).
This is generally the case for relays and contactors. Particular attention must be paid to this issue for semiconductor switching devices.
Technical specifications of sensors and actuators
Refer to the manuals of the fail-safe modules for technical specifications to assist you in selecting sensors and actuators.
5.2.3
Capacitive crosstalk of digital input/output signals
Readback errors may occur on the F-DQ modules if the fail-safe digital output signals and fail-safe digital input signals are routed through a single cable.
Cause: Capacitive crosstalk
During the bit pattern test of the outputs or the sensor supply of the inputs, the steep switching edge of the output drivers caused by the coupling capacitance of the line may result in crosstalk to other non-activated output or input channels. This may then lead to a response of the readback circuit in these channels. The module detects a cross circuit/short circuit and performs a safety-related shutdown.
Remedy:
● Separate cables for F-DI modules, F-DQ modules or non-fail-safe DQ modules
● Coupling relay or diodes in the outputs
● Disable the short-circuit test of the sensor supply if safety class requirements allow it.
Cause: magnetic crosstalk
Note that an inductive load connected to the F-DQ channels can induce capacitive coupling of a strong magnetic field.
Solution:
● Spatially disconnect the inductive loads or shield against the magnetic field.
● Configure the "Max. readback time dark test" to 50 ms or higher.

5.3 Operation on grounded infeed
5.3
Introduction
Operation on grounded infeed
Information is provided below on the overall configuration of an S7-1500 automation system/ET 200MP distributed I/O system on a grounded infeed (TN-S system). The specific subjects discussed are:
● Disconnecting devices, short-circuit and overload protection to IEC 60364 (corresponding to DIN VDE 0100) and IEC 60204 (corresponding to DIN VDE 0113)
● Load current supplies and load circuits
Grounded infeed
In the case of grounding incoming supplies (TN-S system) the neutral conductor (N) and the protective conductor (PE) are each grounded. Both conductors form a part of the overvoltage concept. When a plant is in operation, the current flows across the neutral conductor. When a fault occurs, for example a single ground fault between a live conductor and ground, the current flows through the protective conductor.
Safe galvanic isolation (SELV/PELV in accordance with IEC 60364-4-41)
Load current supplies/system power supplies with 24 V DC supply require safe electrical separation. This protection is designated as SELV (Safety Extra Low Voltage)/PELV
(Protective Extra Low Voltage) in accordance with IEC 60364-4-41.
The wiring of SELV/PELV circuits must be separated from the wiring of other circuits that are not SELV/PELV, or the insulation of all conductors must be rated for the higher voltage.

The reference potential of the S7-1500 automation system/ ET 200MP distributed I/O system is connected with the mounting rail through a high-resistance RC combination in the
CPU/interface module. In this way, high-frequency interference currents are conducted and electrostatic charges are avoided. Despite the grounded mounting rail, the reference potential of the S7-1500 automation system/ET 200MP distributed I/O system has to be considered as ungrounded due to the high-resistance connection.
If you want to configure the S7-1500 automation system/ET 200MP distributed I/O system with grounded reference potential, connect the M connection of the CPU/interface module galvanically with the protective conductor.

Introduction
Connecting system power supply and load current supply
In the delivery condition of the system power supplies/load current supplies, power connectors are inserted. The modules and the associated power connectors are coded. The coding is effected by means of two coding elements - one coding element is located in the module, and the other in the power connector. The system power supplies/load current supplies use identical power connectors for the voltage connection.
The coding element prevents the insertion of a power connector into a different type of system power supply/load current supply.

Introduction
Front connector for the I/O modules
The sensors and actuators of your plant are connected to the automation system by means of front connectors. Wire the sensors and actuators to the front connector and then plug it into the I/O module. You can either wire the front connector in the "pre-wiring position" that makes convenient wiring possible, or completely, before you insert it into the I/O module.
You can remove the front connector easily from the I/O module with the wiring attached. This means it is not necessary to loosen the wiring when you replace the module.

Wiring
5.10 Front connector for the I/O modules
Properties of the front connectors
The three different front connectors are characterized as follows:
● 40 clamping points each
● Connection system: Screw terminal (for 35 mm modules only) or push-in terminal
● Module width: 35 mm or 25 mm
● If you want to supply load groups with the same potential (non-isolated), use the potential bridges supplied for the front connector (with 35 mm width) for digital I/O modules. In four locations: 9 and 29, 10 and 30, 19 and 39, 20 and 40, the terminals can be bridged by means of potential bridges. Advantage: Reduction of the wiring effort.
Note
Use of potential bridges
The use of potential bridges depends on the relevant module used.
Potential bridges must not be used for 230 V modules. Use the potential bridges only with a maximum supply voltage of 24 V DC. The current capacity per potential bridge is 8 A maximum.
Owing to the different assignment for analog I/O modules, potential bridges must not be used.
The front connectors for 25 mm modules have no potential bridges.
Observe the instructions and wiring rules in the product manual of the respective I/O module when using potential bridges.
● In the delivery state a coding element is located in the module. When the front connector is first inserted into the I/O module, a part of the coding element clips onto the front connector. When the front connector is removed from the I/O module, one part of the coding element remains in the front connector, and the other part remains in the I/O module. The insertion of a front connector that is not suited to the module is thereby mechanically prevented. This ensures, for example, that the front connector with the coding element of a digital module cannot be inserted into an analog module.
Properties of the front connectors on fail-safe modules
In as-delivered condition, a fail-safe module not only has a mechanical coding element but also an electronic rewritable memory for the PROFIsafe address. This is the electronic coding element.
When the front connector is inserted in the F-module, the electronic coding element latches fully into place in the front connector. If you remove the front connector from the F-module, the memory with the PROFIsafe address of the fail-safe module remains in the front
connector (see section Replacing a front connector (Page 209)).

Additional information on the use of the potential bridges can be found in the product manual for the respective I/O module.

Bring the front connector into the pre-wiring position. To do this, hook the front connector into the bottom of the I/O module and swivel the front connector upward until the front connector latches (Figure 3).
Result: In this position, the front connector still protrudes from the I/O module (Figure 4).
However, front connector and I/O module are not yet electrically connected. By means of the pre-wiring position, you can easily wire the front connector.

Introduction

By configuring the individual hardware components, assigning their parameters, and connecting them, you communicate to the S7-1500 automation system/ET 200MP distributed I/O system its preset configuration and operating principle. You perform the work needed for this in the device and network views in STEP 7.
"Configuring" is understood to mean the arranging, setup and networking of devices and modules within the device view or network view of STEP 7. STEP 7 graphically represents modules and racks. Just like "real" module racks, the device view allows the insertion of a defined number of modules.
When the modules are inserted, STEP 7 automatically assigns the addresses and a unique hardware identifier (HW identifier). You can change the addresses later. The HW identifiers cannot be changed.
At startup, the system components compare the configured preset configuration with the actual configuration of the system. By means of parameter assignment, you can specify the response of the CPU to errors in the hardware configuration.
"Assigning parameters" is understood to mean setting the properties of the components used (CPU, modules).
The hardware configuration (result of "configuring" and "assigning parameters") is compiled and downloaded to the CPU. The CPU then connects to the configured components and transfers their configuration and parameters. Modules can be replaced very easily because when a new module is inserted, its configuration and parameters are transferred again.

Introduction
Reading out the configuration
When a connection exists to a physically present CPU, you can load the configuration of this
CPU (including centrally present modules) from the device into your project using the
"Hardware detection" function. You do not need to manually configure the CPU and the centrally present modules, as the physical configuration is read out automatically.
If a CPU and the centrally present modules have already been configured and you want to load the current configuration and parameters in a new project, it is advisable to use the
"Upload device as new station" function. For additional information about this function, refer
to section Backing up and restoring the CPU configuration (Page 179).
Procedure for reading out an existing configuration
1.
Create a new project and configure an "Unspecified CPU 1500".

Address assignment
6.1.2.1
Introduction
Addressing - overview
In order to address the automation components or I/O modules, unique addresses must be assigned to them. The various address areas are explained below.
I/O address
I/O addresses (input/output addresses) are required in the user program to read inputs and set outputs.
STEP 7 automatically assigns input and output addresses when modules are configured.
Each module uses a continuous range of input and/or output addresses corresponding to its volume of input and output data.
Figure 6-5 Example with input / output addresses from STEP 7
The address areas of the modules are assigned by default to the process image partition 0
("Automatic updating"). This process image partition is updated in the main cycle of the CPU.
Device address (e.g., Ethernet address)
Device addresses are addresses of modules with interfaces to a subnet (e.g., IP address or
PROFIBUS address). They are required in order to address the various devices on a subnet, e.g., in order to download a user program.

Introduction
Addressing digital modules
The addressing of digital modules is described below. In your user program, you require the addresses of the channels of the digital module.
Digital module addresses
The address of a digital module's input or output is composed of the byte address and the bit address. The channels of the digital module are assigned bit addresses.
Example: I 1.2
The example consists of:
I Input -
1 Byte address The byte address depends on the module start address
2 Bit address You read the bit address from the module
When you insert a digital module into a free slot, STEP 7 assigns a default address. You can change the proposed default address in STEP 7.

Value status
The value status is additional binary information of a digital input or output signal. It is entered simultaneously with the process signal in the process image input and provides information about the validity of the input or output signal.
If you enable the value status for a digital module, then additional bytes are allocated in the input address area. Each bit in the value status is assigned to a channel and provides information about the validity of the process value. You can find the assignment in the product manual for the respective I/O module.
The value status is influenced by all diagnostics that might falsify the process value, e.g. wire break, short-circuit.

: A valid process value is being output or read for the channel.
● 0

: A substitute value is being output for the channel, or the channel is deactivated, faulty or inaccessible.

Introduction
Addressing analog modules
The addressing of analog modules is described below. In your user program, you require the addresses of the channels of the analog module.
Analog module addresses
The address of an analog channel is always a word address. The channel address depends on the module start address. The channel addresses are automatically assigned during configuration in STEP 7. Based on the module start addresses, the assignment of the channel addresses occurs in increasing sequence (in the following figure, the module start address is 256).
When you insert an analog module into a free slot, STEP 7 assigns a default address. You can change the assigned default address in STEP 7.

6.1.3
Process images and process image partitions
6.1.3.1
Process image - overview
Process image of the inputs and outputs
When the user program addresses the input (I) and output (O) operand areas, it does not query the signal states directly from the I/O modules. Instead, it accesses a memory area of the CPU. This memory area contains an image of the signal states and is called the process image.
Advantages of the process image
A process image allows you to access a consistent image of process signals during cyclic program execution. If a signal state at an input module changes during program processing, the signal state is retained in the process image. The process image is not updated until the next cycle.
112
Automation system
System Manual, 09/2016, A5E03461182-AD
Configuring
6.1 Configuring the CPU
Consistency of the process image
When the process image is updated, the S7-1500 accesses the data of each submodule as consistent data. The maximum data width that is accessed as consistent data for each submodule is dependent on the IO system. For PROFINET IO, for example, this data width is 1024 bytes.
32 process image partitions
By means of process image partitions, the CPU synchronizes the updated inputs/outputs of particular modules with defined user program sections.
In the S7-1500 automation system, the overall process image is subdivided into up to 32 process image partitions (PIP).
PIP 0 (automatic update) is automatically updated in each program cycle and is assigned to
OB 1.
Process image partitions PIP 1 through PIP 31 can be assigned to the other OBs. In
STEP 7, this assignment occurs during configuration of the I/O modules.
After the OB has been started, the assigned process image partition of inputs is updated by the system and the process signals are read in. At the end of the OB the outputs of the assigned process image partition are written directly to the peripheral outputs by the system without having to wait for the termination of the cyclic program processing.
6.1.3.2
Assign process image partitions to an OB
Update process image partition
You can assign a process image partition to an OB. In this case, the process image partition is automatically updated.
The process image partition of the inputs (PIPI) is always read in/updated before the processing of the associated OB. The process image partition of the outputs (PIPQ) is always output at the end of the OB.
The following figure illustrates the updating of a process image partition.

Configuring
6.1 Configuring the CPU
6.1.3.3
Update process image partitions in the user program
Requirements
As an alternative to the automatic updating and to updating by assignment to an OB, you can use the instruction "UPDAT_PI" or the instruction "UPDAT_PO" at the start or the at the end of the respectively assigned OB to update the process image. In STEP 7, these instructions are available on the "Instructions" Task Card under "Extended instructions" and may be called from any point in the program.
Requirements for updating process image partitions with the "UPDAT_PI" and "UPDAT_PO" instructions:
● The process image partitions cannot be assigned to any OB, i.e. they cannot be automatically updated.
● PIP 0 (automatic update) can likewise not be updated with the "UPDAT_PI" and
"UPDAT_PO" instructions.
UPDAT_PI: Update process image partition of the inputs
With this instruction you read the signal states from the input modules into the process image partition of the inputs (PIPI).
UPDAT_PO: Update process image partition of the outputs
With this instruction you transmit the process image partition of the outputs to the output modules.
Isochronous mode interrupt OBs
In the isochronous mode interrupt OBs you use the instructions "SYNC_PI" and "SYNC_PO" to update the process image partitions. Additional information on isochronous mode interrupt
OBs is available in the STEP 7 online help.
Direct I/O access to the inputs and outputs of the module
You also have direct read and write access to the I/O, as an alternative to access via the process image, should direct access be required for programming reasons. A direct (write)
I/O access also writes the process image. This prevents the situation where a subsequent output of the process image overwrites the value written via direct access again.

If the maximum cycle time has been exceeded twice within a cycle, the CPU always switches to STOP regardless of whether you have configured OB80.
4)
You can find additional information about these event sources and the runtime behavior in the S7-1500 Motion Control function manual.
Assignment between event source and OBs
The type of OB determines where you make the assignment between OB and event source:
● With hardware interrupts and isochronous mode interrupts, the assignment is made during the configuration of the hardware or when the OB is created.
● For MC servo, MC pre-servo, MC post-servo and MC interpolator, STEP 7 automatically assigns OBs 91/92 as soon as a technology object is added.
● For all other types of OB, the assignment is made when the OB is created, where applicable after you have configured the event source.
For hardware interrupts, you can change an assignment which has already been made during runtime with the instructions ATTACH and DETACH. In this case, only the actually effective assignment changes, and not the configured assignment. The configured assignment takes effect after loading, and upon each startup.
The CPU ignores hardware interrupts to which you did not assign an OB in your configuration or which occur after the DETACH instruction. The check as to whether an OB is assigned to an event does not take place when the associated event occurs, but only when the hardware interrupt actually has to be executed.

Basics of program execution
7.1 Events and OBs
OB priority and runtime behavior
If you have assigned an OB to the event, the OB has the priority of the event. S7-1500 CPUs support the priority classes 1 (lowest) to 26 (highest). The following items are essential to the execution of an event:
● Call and execution of the assigned OB
● The update of the process image partition of the assigned OB
The user program processes the OBs exclusively on a priority basis. This means the program processes the OB with the highest priority first when multiple OB requests occur at the same time. If an event occurs that has a higher priority than the currently active OB, this
OB is interrupted. The user program processes events of the same priority in order of occurrence.
Note
Communication
The communication (e.g. test functions with the PG) always works with priority 15. To prevent extending the program runtime unnecessarily in time-critical applications, these OBs should not be interrupted by communication. Assign a priority > 15 for these OBs.

Basics of program execution
7.2 CPU overload behavior
7.2
CPU overload behavior
Requirements
For the event scenarios considered in the following section, it is assumed that you have assigned an OB to each event source and that these OBs have the same priority. The second condition, in particular, is only for the sake of a simplified representation.
Principle of CPU overload behavior
An occurring event triggers the execution of the associated OB. Depending on the OB priority and the current processor load, a time delay may occur before the OB is executed when there is an overload. The same event can therefore occur once or several times before the user program processes the OB belonging to the preceding event. The CPU treats such a situation as follows: The operating system queues the events in the queue associated with their priority in the order of their occurrence.
To control temporary overload situations, you can limit the number of queued events that originate from the same source. The next event is discarded as soon as the maximum number of pending triggers of a specific cyclic interrupt OB, for example, is reached.
An overload occurs when events which originate from the same source occur faster than they can be processed by the CPU.
More detailed information is provided in the following sections.
Discarding similar events or fetching them later
Below, the term "similar events" refers to events from a single source, such as triggers for a specific cyclic interrupt OB.
The OB parameter "Events to be queued" is used to specify how many similar events the operating system places in the associated queue and therefore post-processes. If this parameter has the value 1, for example, exactly one event is stored temporarily.
Note
Post-processing of cyclic events is often not desirable, as this can lead to an overload with
OBs of the same or lower priority. Therefore, it is generally advantageous to discard similar events and to react to the overload situation during the next scheduled OB processing. If the value of the "Events to be queued" parameter is low, this ensures that an overload situation is mitigated rather than aggravated.
If the maximum number of triggers is reached in the queue for a cyclic interrupt OB (Cyclic interrupt), for example, each additional trigger is only counted and subsequently discarded.
During the next scheduled execution of the OB, the CPU provides the number of discarded triggers in the "Event_Count" input parameter (in the start information). You can then react appropriately to the overload situation. The CPU then sets the counter for lost events to zero.
If the CPU, for example, first discards a trigger for a cyclic interrupt OB, its further behavior depends on the OB parameter "Report event overflow into diagnostic buffer": If the check box is selected, the CPU enters the event DW#16#0002:3507 once in the diagnostics buffer for the overload situation at this event source. The CPU suppresses additional diagnostics buffer entries of the event DW#16#0002:3507 until all events from this source have been post-processed.
120

System Manual, 09/2016, A5E03461182-AD
Basics of program execution
7.3 Asynchronous instructions
Threshold mechanism for time error OB request
The OB parameter "Enable time error" is used to specify whether the time error OB is to be called at a defined overload for similar events. You can find the OB parameter "Enable time error" in the properties of the OB in the "Attributes" category.
When you enable the time error OB (check box selected), use the OB parameter "Event threshold for time error" to specify the number of similar events in the queue as of which the time error OB is called. If this parameter has the value 1, for example, the CPU enters the event DW#16#0002:3502 once in the diagnostics buffer and requests the time error OB when the second event occurs. The CPU suppresses additional diagnostics buffer entries of the event DW#16#0002:3502 until all events from this source have been post-processed.
In the event of an overload, you therefore have the option of programming a reaction well before the limit is reached for similar events and thus before the events are discarded.
The following value range applies to the "Event threshold for time error" parameter:
1 ≤ "Event threshold for time error" ≤ "Events to be queued".
7.3
Asynchronous instructions
Difference between synchronous and asynchronous instructions
During program execution a distinction is made between synchronous and asynchronous instructions.
The "synchronous" and "asynchronous" properties relate to the temporal relationship between the call and execution of the instruction.
The following applies to synchronous instructions: When the call of a synchronous instruction is complete, execution of the instruction is also complete.
This is different in the case of asynchronous instructions: When the call of an asynchronous instruction is complete, execution of the asynchronous instruction is not necessarily complete yet. This means the execution of an asynchronous instruction can extend over multiple calls. The CPU processes asynchronous instructions in parallel with the cyclic user program. Asynchronous instructions generate jobs in the CPU for their processing.
Asynchronous instructions are usually instructions for transferring data (data records for modules, communication data, diagnostic data, etc.).

Parallel processing of asynchronous instruction jobs
A CPU can process several asynchronous instruction jobs in parallel. The CPU processes the jobs in parallel under the following conditions:
● Several asynchronous instruction jobs are called at the same time.
● The maximum number of simultaneously running jobs for the instruction is not exceeded.
The figure below shows the parallel processing of two jobs of the WRREC instruction. The two instructions are executed simultaneously for a certain duration.

7.3 Asynchronous instructions
Assignment of call to job of the instruction
To execute an instruction over multiple calls, the CPU must be able to uniquely relate a subsequent call to a running job of the instruction.
To relate a call to a job, the CPU uses one of the following two mechanisms, depending on the type of the instruction:
● Using the instance data block of the instruction (for "SFB" type)
● Using job-identifying input parameters of the instruction. These input parameters must match in each call during processing of the asynchronous instruction.
Example: A job of the "Create_DB" instruction is identified by input parameters
LOW_LIMIT, UP_LIMIT, COUNT, ATTRIB and SRCBLK.
The following table shows which input parameters you use to identify which instruction.

7.3 Asynchronous instructions
Status of an asynchronous instruction
An asynchronous instruction shows its status via the block parameters STATUS/RET_VAL and BUSY. Many asynchronous instructions also use the block parameters DONE and
ERROR.
The figure below shows the two asynchronous instructions WRREC and CREATE_DB.
①
The input parameter REQ starts the job to execute the asynchronous instruction.
②
The output parameter DONE indicates that the job was completed without error.
③
The output parameter BUSY indicates whether the job is currently being executed. When
BUSY =1, a resource is allocated for the asynchronous instruction. When BUSY = 0, the resource is free.
④
The output parameter ERROR indicates that an error has occurred.
⑤
The output parameter STATUS/RET_VAL provides information on the status of the job execution. The output parameter STATUS/RET_VAL receives the error information after the occurrence of an error.
Figure 7-3 Block parameters of asynchronous instructions using the instructions WRREC and
CREATE_DB as examples.
Summary
The table below provides you with an overview of the relationships described above. It shows in particular the possible values of the output parameters if execution of the instruction is not complete after a call.
Note
You must evaluate the relevant output parameters in your program after each call

Use of resources
Asynchronous instructions use resources in the CPU during their execution. The resources are limited depending on the type of CPU and instruction; the CPU can simultaneously process only a maximum number of asynchronous instruction jobs. The resources are available again after a job has been processed successfully or with errors.
Example: For the RDREC instruction, an S7-1500 CPU can process up to 20 jobs in parallel.
If the maximum number of simultaneously running jobs for an instruction is exceeded, the instruction returns error code 80C3 (lack of resources) in the STATUS block parameter. The execution of the job is stopped until a resource becomes free again.
Note
Lower-level asynchronous instructions
Some asynchronous instructions use one or more lower-level asynchronous instructions for their processing. This dependence is shown in the tables below.
Please note that with multiple lower-level instructions, only one lower-level resource is typically allocated at a time.

Further measures for protecting the CPU
The following measures additionally increase the protection against unauthorized access to functions and data of the S7-1500 CPU from external sources and via the network:
● Deactivation of the Web server
● Deactivation of the OPC UA server (you can find additional information on the security mechanisms for OPC UA server in the Communication
( https://support.industry.siemens.com/cs/de/de/view/59192925/en ) Function Manual)
● Deactivation of the time synchronization via an NTP Server
● Deactivation of the PUT/GET communication
When you use Web server, protect your S7-1500 automation system against unauthorized access:
● By setting password-protected access rights for specific users in the user administration.
● By using the pre-set option "Permit access only via HTTPS".
The option allows access to the web server only with the secure hypertext transmission protocol HTTPS.

8.2 Configuring access protection for the CPU
8.2
Introduction
Configuring access protection for the CPU
The CPU offers four access levels to limit access to specific functions.
By setting up the access levels and the passwords for a CPU, you limit the functions and memory areas that are accessible without entering a password. The individual access levels as well as their associated passwords are specified in the object properties of the CPU.
Access levels of the CPU
Table 8- 1 Access levels and access restrictions
Access levels Access restrictions
Complete access (no protection)
The hardware configuration and the blocks can be read and changed by all users.
Read access With this access level, read-only access to the hardware configuration and the blocks is possible without entering a password, which means you can download hardware configuration and blocks to the programming device. In addition, HMI access and access to diagnostics data is possible.
Without entering the password, you cannot load any blocks or hardware configuration into the CPU. Additionally, the following are not possible without the password: Writing test functions and firmware update (online).
HMI access
No access
(complete protection)
With this access level only HMI access and access to diagnostics data is possible without entering the password.
Without entering the password, you can neither load blocks and hardware configuration into the CPU, nor load blocks and hardware configuration from the CPU into the programming device.
Additionally, the following are not possible without the password: Test functions, changing the operating mode (RUN/STOP), firmware update and display of online/offline comparison status.
When the CPU has complete protection, no read or write access to the hardware configuration and the blocks is possible (without access authorization in the form of a password). HMI access is also not possible. The server function for PUT/GET communication is disabled in this access level (cannot be changed).
Authentication with the password will again provide you full access to the CPU.
A list of which functions are available in the different access levels is available in the "Setting options for the protection" entry in the STEP 7 online help.
Automation system
System Manual, 09/2016, A5E03461182-AD

Protection
8.2 Configuring access protection for the CPU
Properties of the access levels
Each access level allows unrestricted access to certain functions without entering a password, e.g. identification using the "Accessible devices" function.
The CPU's default setting is "No restriction" and "No password protection". In order to protect access to a CPU, you must edit the properties of the CPU and set up a password. In the default access level "Full access (no protection)" every user can read and change the hardware configuration and the blocks. A password is not set and is also not required for online access.
Communication between the CPUs (via the communication functions in the blocks) is not restricted by the access level of the CPU, unless PUT/GET communication is deactivated in the "No access" (complete protection) access level.
Entry of the right password allows access to all the functions that are allowed in the corresponding level.
Note
Configuring an access level does not replace know-how protection
Configuring access levels offers a high degree of protection against unauthorized changes on the CPU by restricting the rights to download the hardware and software configuration to the CPU. However, blocks on the SIMATIC memory card are not write- or read-protected.
Use know-how protection to protect the code of blocks on the SIMATIC memory card.
Behavior of functions with different access levels
The STEP 7 online help includes a table which lists the online functions that are available in the different access levels.

8.2 Configuring access protection for the CPU
Parameterizing the procedure at access levels
To configure the access levels of an S7-1500 CPU, follow these steps:
1.
Open the properties of the S7-1500 CPU in the Inspector window.
2.
Open the "Protection" entry in the area navigation.
A table with the possible access levels appears in the Inspector window.
Figure 8-1 Possible access levels
3.
Activate the desired protection level in the first column of the table. The green check marks in the columns to the right of the respective access level show you which operations are still available without entering the password. In the example (see above), read access and HMI access is still possible without a password.
4.
In the "Enter password" column, specify a password for the access level "Full access" in the first row. In the "Confirm password" column, enter the selected password again to guard against incorrect entries.
Ensure that the password is sufficiently secure, in other words, that is does not follow a pattern that can be recognized by a machine!
5.
Assign additional passwords to other access levels as needed, if the selected access level calls for this.
6.
Download the hardware configuration for the access level to take effect.
The CPU logs the entry of the correct or incorrect password and any changes in the configuration of the access levels by a corresponding entry in the diagnostics buffer.

Before an online function is executed, the necessary permission is checked and, if necessary, the user is prompted to enter a password. The functions protected by a password can only be executed by one programming device/PC at any one time. Another programming device/PC cannot log on.
Access authorization to the protected data is in effect for the duration of the online connection, or until the access authorization is manually rescinded with "Online > Delete access rights".
Access to a password-protected CPU in the RUN mode can be limited locally in the display so that access with a password is also not possible.
Access level for F-CPUs
For the fail-safe CPUs, there is an additional access level in addition to the four described access levels. For additional information on this access level, refer to the description of the fail-safe system SIMATIC Safety Programming and Operating Manual SIMATIC Safety -
Configuring and Programming
( http://support.automation.siemens.com/WW/view/en/54110126 ).

Using the display to set additional access protection
Blocking access to a password-protected CPU
On the display of an S7-1500 CPU, you can block access to a password-protected CPU
(local lock). The access lock is only in effect, when the mode selector is in the RUN position.
The access block requires a configured protection level in STEP 7. The access block is effective regardless of the password protection. This means that even if someone accesses the CPU via a connected programming device and has entered the correct password, access to the CPU remains disabled.
The access block can be set separately for each access level on the display, so that, for example, read access is allowed locally, but write access is not allowed locally.
Procedure
If an access level with a password is configured in STEP 7, access can be blocked using the display.
Proceed as follows to set the local access protection for an S7-1500 CPU on the display:
1.
On the display, select Settings > Protection menu.
2.
Confirm the selection using "OK", and configure for each access level, whether access at the RUN mode selector is allowed or not:
Allow: Access to the CPU is possible with the corresponding password in STEP 7.
Disabled in RUN: When the mode selector is in the RUN position, no more users with privileges for this access level can log in to the CPU, even if they know the password. In
STOP mode, access is possible with password entry.
Access protection for the display
A password can be configured for the display in STEP 7 in the properties of the CPU so that the local access protection is protected by a local password.
8.4
Using the user program to set additional access protection
Access protection by means of the user program
In addition to restricting access to the display, you can also restrict access to a passwordprotected CPU in STEP 7 using the instruction ENDIS_PW. You can find a description of this block in the online help under the keyword "ENDIS_PW: Limit and enable password legitimation".

Application
Know-how protection
You can use know-how protection to protect one or more blocks of the OB, FB, FC type and global data blocks in your program from unauthorized access. You can enter a password to restrict access to a block. The password offers high-level protection against unauthorized reading or manipulation of the block.
Readable data
If a block is know-how protected, only the following data is readable without the correct password:
● Block title, comments and block properties
● Block parameters (INPUT, OUTPUT, IN, OUT, RETURN)
● Call structure of the program
● Global tags without information on the point of use
Further actions
Further actions that can be carried out with a know-how protected block:
● Copying and deleting
● Calling within a program
● Online/offline comparison
● Load
Global data blocks and array data blocks
You cannot provide global data blocks (global DBs) with know-how protection. Users who do not possess the valid password can read the global data block but not change it.
You cannot provide array data blocks (array DBs) with know-how protection.

Introduction
Standard machine projects
Standard machine projects are STEP 7 projects that use a set of innovative functions allowing simple configuration and commissioning of flexible automation solutions for standard machines or for machines with a modular structure.
A hardware configuration consisting of an S7-1500 CPU as the IO controller and any connected IO devices represents a "PROFINET IO system master". This master is configured with a maximum configuration based on which various options can be derived for different standard machines, for example with different configuration variants of the IO system.
Greater flexibility at all levels
Standard machine projects have the following central characteristics:
● From one project (IO system master) with an engineered maximum configuration, different variants of a standard machine can be loaded (IO system options). The standard machine project covers all variants (options) of the IO system.
● An IO system option can be integrated in an existing network locally using simple tools.
Flexibility is provided in more ways than one:
● With suitable configuration, adaptation of the IP address parameters of the IO controller is possible locally using simple tools. This allows a standard machine to be integrated in different plants with little effort or to be included in a network several times.
IO systems with this property are known as multiple use IO systems.
● With suitable configuration and programming, different setups of IO system options can be operated locally that differ in terms of the selection of IO devices used or in terms of the arrangement of the IO devices.
Since the specific configuration of the IO system is controlled by the user program, this is known as configuration control for IO systems.
● Independently of the functions described above, with suitable configuration and programming, you can use different station options of central devices or distributed
I/O devices in one project. The devices can be different in terms of the selection and arrangement of the modules.
Since the concrete configuration of the station is controlled by the user program, this is also known as configuration control.

9.2 Configuration control (option handling)
9.2
Introduction
Configuration control (option handling)
With configuration control (option handling), you handle various standard machine configuration levels in one project without having to change the hardware configuration or user program.
Operating principle of configuration control
Configuration control enables you to operate different configuration levels of a standard machine with a single configuration of the S7-1500 automation system/ET 200MP distributed
I/O system.
● A station master (maximum configuration) is configured in a project. The station master comprises all modules needed for all possible equipment components of a modular standard machine.
● Provision is made in the user program of the project for various station options for the different configuration levels of the standard machine and for selection of a station option.
A station option uses, for example, only some of the modules of the station master and these modules are not inserted in the configured order.
● Manufacturers of standard machines select a station option for a configuration level of the standard machine. They do not have change the project or download the modified configuration.
You use a control data record you have programmed to notify the CPU/interface module as to which modules are missing or located on different slots in a station option as compared to the station master. The configuration control has no effect on the parameter assignment of the modules.
The configuration control allows you to flexibly vary the centralized/distributed configuration.
As a precondition for this, the station option must be able to be derived from the station master.

Flexible automation concepts
9.2 Configuration control (option handling)
Rules
Observe the following rules:
● Slot entries in the control data record outside the station master are ignored by the
CPU/interface module.
● The control data record must contain the entries up to the last slot of the station option.
● Each slot of a station option may only be present once in the control data record.
● Each slot of a station option may only be assigned to one slot in the station master.
● System power supplies (PS) can also be subject to configuration control.
Note
Configuration control for system power supplies
In the case of a configuration (station option) loaded using a data record, STEP 7 does not automatically check compliance with the power budget.
Ensure that the power supplied in each power segment of the station option is greater than or equal to the power drawn.
You can find additional information in the section Power balance calculation (Page 45).
Using communication modules
● Point-to-point communication modules:
Point-to-point communication modules can be used without any restrictions for the configuration control.
● PROFINET/Ethernet and PROFIBUS communication modules:
CPUs as of firmware version V1.7 support configuration control when using
PROFINET/Ethernet or PROFIBUS communication modules. If PROFINET/Ethernet or
PROFIBUS communication modules, such as a CM 1542-5 (DP master or DP slave) are inserted in the central configuration, these communication modules cannot be influenced by the configuration control. You must therefore leave these modules in the slots preassigned in the station master and enter the slot numbers from the station master in the control data record ("Station option slot = Station master slot"). In a station option, all slots up to the communication module furthest from the CPU must be present in the control data record. Maximum flexibility is achieved by inserting the communication modules directly to the right of the CPU.

9.2 Configuration control (option handling)
Special requirements relating to the transfer of the control data record to the CPU
● If you have enabled configuration control, the CPU is not ready for operation without a control data record. The CPU returns from startup to STOP if a valid control data record is not transferred in the startup OB (for example, OB 100). The central I/O is not initialized in this case. The cause for STOP mode is entered in the diagnostics buffer.
Note
If an incorrect control data record is transferred to the CPU in the startup OB, the startup of the CPU may be prevented.
In this case, perform a reset to factory settings of the CPU and then transfer a correct control data record.
● The CPU processes the WRREC instruction for transferring the control data record asynchronously. For this reason, you must call WRREC in the startup OB (for example,
OB 100) repeatedly in a loop until the output parameters "BUSY" and "DONE" indicate that the data record has been transferred.
– Tip: To program the loop, use the SCL programming language with the REPEAT ...
UNTIL instruction.
REPEAT
"WRREC_DB"(REQ := "start_config_control",
ID := "Local Configuration",
INDEX := 196,
LEN := "conf_LEN",
DONE => "conf_DONE",
BUSY => "conf_BUSY",
RECORD := "ConfDB".ConfigControl["ConfDB".Option],
//Selection of control data record*
ERROR => "conf_ERROR",
STATUS => "conf_STATUS");
UNTIL NOT "conf_BUSY"
END_REPEAT;
*Selection of the station option in the user program: In order for the CPU to know which station option you want to operate, you must set up a possibility to select between the various control data records in the user program. You can implement the selection, for example, via an Int tag that references an array element. Note that the tag for selecting the control data record must be located in the retentive memory area.
If the tag is not retentive, it will be initialized during startup of the CPU and will thus be unavailable for selection of the station option.
– In the graphical programming languages, you implement the loop using instructions for program control.

9.2 Configuration control (option handling)
Example in FBD: Use the LABEL (jump label) and JMP (jump at RLO=1) instructions to program a loop.
Figure 9-8 WRREC
● The control data record is stored retentively in the CPU. Note:
– The retentivity of the control data record is independent of the retentivity settings in the
STEP 7 memory area. This means that the memory area in which the control data record is configured does not have to be configured as retentive for this purpose.
– If you write a control data record with modified configuration, the original data record
196 is deleted and the new data record 196 is saved retentively. The CPU will then restart with the modified configuration.

Flexible automation concepts
9.2 Configuration control (option handling)
Special requirements relating to the transfer of the control data record to the interface module
● If you have enabled configuration control, the ET 200MP station is not ready for operation without a control data record. As long as no valid control data record has been transferred, the I/O modules are considered as failed by the CPU and exhibit substitute value behavior. The interface module continues to exchange data.
● The control data record is stored retentively in the interface module. Note:
– If the configuration is unchanged, you do not have to rewrite the control data record 196 during restart.
– If you write a control data record with modified configuration, this will result in a station failure in the distributed I/O system. The original data record 196 is deleted and the new data record 196 is saved retentively. The station will then restart with the modified configuration.
9.2.4
Behavior during operation
Effect of discrepancy between station master and station option
For the online display and for the display in the diagnostics buffer (module OK or module faulty), the station master is always used and not the differing station option.
Example: A module outputs diagnostics data. This module is configured in slot 4 in the station master, but is inserted in slot 3 in the station option (missing module; see example in the next section). The online view (station master) shows an incorrect module in slot 4. In the real configuration, the module in slot 3 indicates an error via an LED display.
Response to modules that are not present
If modules are entered as not present in the control data record, the automation system behaves as follows:
● Modules designated as not present in the control data record do not supply diagnostics and their status is always OK. The value status is OK.
● Direct writing access to the outputs that are not present or writing access to the process image of outputs that are not present: Remains without effect; no access error is signaled.
● Direct reading access to the inputs that are not present or reading access to the process image of inputs that are not present: Value "0" is supplied; no access error is signaled.
● Write data record to module that is not present: Remains without effect; no error is signaled.
● Read data record from module that is not present: The output parameter STATUS of the instruction RDREC supplies the value 80A3

Inserting the SIMATIC memory card
To insert a SIMATIC memory card, follow these steps:
1.
Open the front cover of the CPU.
2.
Ensure that the CPU is either switched off, or in the STOP mode.
3.
Insert the SIMATIC memory card, as depicted on the CPU, into the slot for the SIMATIC memory card.
Figure 10-1 Slot for the SIMATIC memory card
4.
Insert the SIMATIC memory card with light pressure into the CPU, until the SIMATIC memory card latches.
Removing the SIMATIC memory card
To remove a SIMATIC memory card, follow these steps:
1.
Open the front cover.
2.
Switch the CPU into STOP mode.
3.
Press the SIMATIC memory card into the CPU with light pressure. After audible unlatching of the SIMATIC memory card, remove it.
Only remove the SIMATIC memory card in POWER OFF or STOP mode of the CPU. Ensure that no writing functions (online functions with the programming device, e.g. loading/deleting a block, test functions) are active in STOP mode or were active before POWER OFF.
If you remove the SIMATIC memory card during a write process, the following problems can occur:
● The data content of a file is incomplete.
● The file is no longer readable, or no longer exists.
● The entire content of the card is corrupted.
Also note the following FAQ on the Internet

166
Automation system
System Manual, 09/2016, A5E03461182-AD
Reactions after removing/inserting the SIMATIC memory card
Inserting and removing the SIMATIC memory card in STOP mode triggers a re-evaluation of the SIMATIC memory card. The CPU hereby compares the content of the configuration on the SIMATIC memory card with the backed-up retentive data. If the backed-up retentive data matches the data of the configuration on the SIMATIC memory card, the retentive data is retained. If the data differs, the CPU automatically performs a memory reset (which means the retentive data is deleted) and then goes to STOP.
The CPU evaluates the SIMATIC memory card and indicates this by flashing the RUN/STOP
LED.

Introduction
Operating modes of the CPU
Operating modes describe the states of the CPU. The following operating states are possible via the mode selector:
● STARTUP
● RUN
● STOP
In these operating modes, the CPU can communicate, for example, via the PROFINET IO interface (X1).
The status LEDs on the front side of the CPU indicate the current operating mode.
10.5.1
Function
STARTUP mode
Before the CPU starts to execute the cyclic user program, a startup program is executed.
By suitably programming startup OBs, you can specify initialization tags for your cyclic program in the startup program. That is, you can set up one or several startup OBs in your program, or none at all.

10.5 Operating modes of the CPU
Special features in Startup mode
● All outputs are disabled or react according to the parameter settings for the respective module: They provide a substitute value as set in the parameters or retain the last value output and bring the controlled process to a safe operating mode.
● The process image is initialized.
● The process image is not updated.
In order to read the current state of inputs during STARTUP, you can access inputs by direct I/O access.
In order to initialize outputs during STARTUP, you can write the values via the process image or via direct I/O access. The values are output at the outputs during the transition to the RUN mode.
● The CPU always starts up in a warm restart.
– The non-retentive bit memories, timers and counters are initialized.
– The non-retentive tags in data blocks are initialized.
● During startup, no cycle time monitoring is running yet.
● The CPU processes the startup OBs in the order of the startup OB numbers. The CPU processes all programmed startup OBs regardless of the selected startup mode.
● If a corresponding event occurs, the CPU can start the following OBs in startup:
– OB 82: Diagnostics interrupt
– OB 83: Removal/insertion of modules
– OB 86: Rack error
– OB 121: Programming error (only for global error handling)
– OB 122: Time-out (for global error handling only)
You can find a description of how to use global and local error handling in the STEP 7 online help.
The CPU cannot start all other OBs until after the transition to RUN mode.
Response when expected and actual configurations do not match
The configuration downloaded to the CPU represents the expected configuration. The actual configuration is the actual configuration of the automation system. If the expected configuration and actual configuration deviate from one another, the CPU's behavior is specified by the setting of the hardware compatibility. For additional information about the
hardware compatibility, see the section Operating mode transitions (Page 174).
Canceling a startup
If errors occur during startup, the CPU cancels the startup and returns to STOP mode.
The CPU does not perform startup or interrupts startup under the following conditions:
● You have not inserted a SIMATIC memory card or an invalid one is inserted.
● You have not downloaded a hardware configuration to the CPU.
Parameter assignment of startup behavior
You can assign parameters for the behavior of the CPU in the Startup group of the CPU properties.

Commissioning
10.5 Operating modes of the CPU
Setting the startup behavior
To set the startup behavior, follow these steps:
1.
Select the CPU in the device view of the STEP 7 hardware network editor.
2.
In the properties under "General" select the "Startup" area.
172
Figure 10-2 Setting the startup behavior
①
Sets the startup type after POWER ON
②
Defines the startup behavior for the case where a module in a slot does not correspond to the configured module. This parameter applies to the CPU and to all the modules for which no other setting was selected.
• Startup CPU only if compatible: In this setting a module on a configured slot has to be compatible with the configured module. Compatible means that the module matches the number of inputs and output and must match with respect to its electrical and functional properties.
•
Startup CPU even if mismatch: At this setting the CPU starts up irrespective of the type of module plugged.
For locally used modules you can configure the hardware compatibility in the parameter
"Comparison preset to actual module" individually for each slot. When you change the setting of the hardware compatibility for a module, the setting made at the CPU does not apply for this module.
③
Specifies a maximum period (default: 60000 ms) in which the central and distributed I/O must be ready for operation. The communications modules (CM/CP) are supplied with voltage and communication parameters during the CPU startup. This parameter assignment time grants a period within which the I/O modules connected to the communication module (CM/CP) must be operationally ready.
The CPU goes into RUN mode when the central and the distributed I/O is operationally ready within the parameter assignment time.
If the central and distributed I/O is not ready for operation within the configuration time, the startup characteristics of the CPU depends on the setting of the hardware compatibility.

Example for the "Comparison preset to actual configuration" parameter
"Startup CPU only if compatible"
The DI 32x24VDC HF input module with 32 digital inputs can be a compatible replacement for a DI 16x24VDC HF input module with 16 digital inputs. The pin assignment and all electrical and functional properties are identical.
"Startup CPU even if mismatch"
Instead of a configured digital input module, you insert an analog output module or no module is present in this slot and thus in all subsequent slots. Although the configured inputs cannot be accessed, the CPU starts up.
Note that the user program cannot function correctly in this case and take the appropriate measures.
10.5.2
Function
STOP mode
The CPU does not execute the user program in STOP mode.
All outputs are disabled or react according to the parameter settings for the respective module: They provide a substitute value as set in the parameters or retain the last value output and thus hold the controlled process in a safe operating mode.
10.5.3
RUN mode
Function
In "RUN" mode the cyclic, time-driven, and interrupt-driven program execution is performed.
Addresses that are in the "Automatic Update" process image are automatically updated in
each program cycle. See also section Process images and process image partitions
Execution of the user program
Once the CPU has read the inputs, the cyclic program is executed from the first instruction to the last instruction. Events with higher priority, such as hardware interrupts, diagnostic interrupts and communication, can interrupt the cyclic program flow and prolong the cycle time.
If you have configured a minimum cycle time, the CPU will not end the cycle until this minimum cycle time has expired, even if the user program is completed sooner.
The operating system monitors the execution time of the cyclic program for a configurable upper limit known as the maximum cycle time. You can restart this time monitoring at any point in your program by calling the RE_TRIGR instruction.
If the cyclic program exceeds the maximum cycle time, the operating system will attempt to start the time error OB (OB 80). If the OB is not present, the CPU ignores that the maximum cycle time was exceeded. If the cycle monitoring time is exceeded a second time, e.g. while the time error OB is being processed, the CPU goes to STOP mode.

CPU memory reset
Basics of a memory reset
A memory reset on the CPU is possible only in the STOP mode.
During memory reset, the CPU is changed to a so-called "initial status".
This means that:
● An existing online connection between your programming device/PC and the CPU is terminated.
● The content of the work memory and the retentive and non-retentive data (applies only to manual memory reset by the user) are deleted.
● The diagnostics buffer, time of day, and IP address are retained.
● Subsequently the CPU is initialized with the loaded project data (hardware configuration, code and data blocks, force jobs). The CPU copies this data from the load memory to the work memory.
Result:
– If you set an IP address in the hardware configuration ("Set IP address in the project" option) and a SIMATIC memory card with the project is in the CPU, this IP address is valid after the memory reset.
– Data blocks no longer have current values but rather their configured start values.
– Force jobs remain active.
How can I tell if the CPU is performing a memory reset?
The RUN/STOP LED flashes yellow at 2 Hz. After completion the CPU goes into STOP mode, and the RUN/STOP LED is switched on (unchanging yellow).
Result after memory reset
The following table provides an overview of the contents of the memory objects after memory reset.

10.6.1
Automatic memory reset
Possible cause of automatic memory reset
The CPU executes an automatic memory reset if an error occurs that prevents normal further processing.
Causes for such errors can be:
● User program is too large, and can't be completely loaded into work memory.
● The project data on the SIMATIC memory card are damaged, for example because a file was deleted.
● If you remove or insert the SIMATIC memory card and the backed-up retentive data differs in structure from that of the configuration on the SIMATIC memory card.
10.6.2
Manual memory reset
Reason for manual memory reset
Memory reset is required to reset the CPU to its "original state".
CPU memory reset
There are three options for performing a CPU memory reset:
● Using the mode selector
● Using the display
● Using STEP 7
Procedure using the mode selector

Backing up and restoring the CPU configuration
Backup from online device
You will make a number of changes to your plant over time, for example, add new devices, replace existing devices or adapt the user program. If these changes result in undesirable behavior, you can restore the plant to an earlier state. Before you load a changed configuration to the CPU, first use the option "Backup from online device" to create a complete backup of the current device status.
Upload from device (software)
With the option "Upload from device (software)", you load the software project data from the
CPU to an existing CPU in the project.
Upload device as new station
If you are operating a new programming device/PC in the plant, the STEP 7 project that was used to create the plant configuration might not be available. In this case you can use the option "Upload device as new station" to load the device's data into a project in your PG/PC.
Snapshot of the monitor values
You can use the option "Snapshot of the monitor values" to backup the current values of the data block, in order to be able to restore the current values if necessary at a later date.

I&M data
Reading out and entering I&M data
Identification and maintenance data (I&M data) is data saved on the module as read-only
(I data) or read/write (M data) information.
Identification data (I&M0): Manufacturer information about the module that can only be read and is in part also printed on the housing of the module, for example, article number and serial number.
Maintenance data (I&M1, 2, 3): Plant-dependent information, e.g. installation location.
Maintenance data for the S7-1500/ET 200MP is created during configuration and downloaded to the automation system/distributed I/O system.
All modules of the S7-1500/ET 200MP support identification data (I&M0 through I&M3).
The I&M identification data supports you in the following activities:
● Checking the plant configuration
● Locating hardware changes in a plant
● Correcting errors in a plant
Modules can be clearly identified online using the I&M identification data.
You can read out the identification data with STEP 7 (see online help for STEP 7).

Introduction
SIMATIC memory card - overview
The S7-1500 automation system uses a SIMATIC memory card as the program memory.
The SIMATIC memory card is a preformatted memory card compatible with the Windows file system. The memory card is available in different memory sizes and can be used for the following purposes:
● Transportable data carrier
● Program card
● Firmware update card
● Service data cards
If you transfer the user program to the CPU via an online connection, it is written to the load memory of the SIMATIC memory card, which must be in the card slot of the CPU for this to work.
You can also write the SIMATIC memory card in the PG/PC. A commercially available SD card reader is required to write / read the SIMATIC memory card with the programming device / PC. This is used to copy files directly to the SIMATIC memory card using the
Windows Explorer, for example.
A SIMATIC memory card is absolutely required in order to operate the CPU.

Use the serial number for copy protection
You can set up copy protection for CPUs which binds execution of the block to a specific
SIMATIC memory card. Configuration is carried out in STEP 7 in the properties of the block
"Bind to serial number of the SIMATIC memory card".
You can only execute the block if it is on the SIMATIC memory card with the specified serial
number (see section Copy protection (Page 139)).
Removing the SIMATIC memory card
Only remove the SIMATIC memory card in POWER OFF or STOP mode of the CPU. Ensure that no writing functions (online functions with the programming device, e.g. loading/deleting a block, test functions) are active in STOP mode or were active before POWER OFF.
If you remove the SIMATIC memory card during a write process, the following problems can occur:
● The data content of a file is incomplete.
● The file is no longer readable, or no longer exists.
● The entire content of the card is corrupted.
Inserting the SIMATIC memory card in the CPU in STOP mode triggers a re-evaluation of the SIMATIC memory card. The CPU hereby compares the content of the configuration on the SIMATIC memory card with the backed-up retentive data. If the backed-up retentive data matches the data of the configuration on the SIMATIC memory card, the retentive data is retained. If the data differs, the CPU automatically performs a memory reset (which means the retentive data is deleted) and then goes to STOP.
Also note the following FAQ on the Internet
( https://support.industry.siemens.com/cs/ww/en/view/59457183 ) in connection with the removal of the SIMATIC memory card.
Removing the SIMATIC memory card from Windows computers
If you are using the card in a commercially available card reader under Windows, use the
"Eject" function before you remove the card from the card reader. If you remove the card without using the "Eject" function, you may lose data.

Deleting the contents of the SIMATIC memory card
You have the following options for deleting the contents of the SIMATIC memory card:
● Delete files using Windows Explorer
● Format with STEP 7
Note
If you format the card with Windows utilities, you will render the SIMATIC memory card unusable as a storage medium for a CPU.
Deletion of files and folders is permitted, with the exception of the "__LOG__" and
"crdinfo.bin" system files. The CPU needs these system files. If you delete the files, you will no longer be able to use the SIMATIC memory card with the CPU.
If you have deleted the "__LOG__" and "crdinfo.bin" system files, format the SIMATIC memory card as described in the following section.
Formatting the SIMATIC memory card
Note
You may only format a SIMATIC memory card in the CPU; otherwise, the SIMATIC memory card cannot be used in the CPU.
If you want to format the SIMATIC memory card using STEP 7, an online connection to the relevant CPU must exist. The relevant CPU is in the STOP mode.
Proceed as follows to format a SIMATIC memory card:
1.
Open the Online and Diagnostics view of the CPU (either from the project context or via
"Accessible devices").
2.
In the "Functions" folder, select the "Format memory card" group.
3.
Click the "Format" button.
4.
Click "Yes" in response to the confirmation prompt.
Result:
● The SIMATIC memory card is formatted for use in the CPU.
● The data on the CPU is deleted with the exception of the IP address.

Introduction
Setting the card type
You can use the SIMATIC memory card as a program card or as a firmware update card.
Procedure
1.
To set the card type, insert the SIMATIC memory card into the card reader of the programming device.
2.
Select the "SIMATIC Card Reader" folder in the project tree.
3.
In the properties of the selected SIMATIC memory card, specify the card type:
● Program card
You use a program card as an external load memory for the CPU. It contains the entire user program for the CPU. The CPU transfers the user program from the load memory to the work memory. The user program runs in the work memory.
The following folder is created on the SIMATIC memory card: SIMATIC.S7

Data transfer with SIMATIC memory cards
Transferring objects from the project to a SIMATIC memory card
When the SIMATIC memory card is inserted in the programming device or in an external card reader, you can transfer the following objects from the project tree (STEP 7) to the
SIMATIC memory card:
● Individual blocks (multiple selection possible)
In this case, the transfer is consistent, which means that the function takes dependencies between blocks due to block calls into account.
● CPU folder
In this case, all runtime-relevant objects including blocks and the hardware configuration are transferred onto the SIMATIC memory card - just as when downloading.
● Service data
To perform a transfer, you can transfer the objects by dragging and dropping, or use the
"Card Reader/USB memory > Write to memory card" command in the "Project" menu.
Firmware update via SIMATIC memory card
You can find information on how to perform a firmware update via SIMATIC memory card in

Introduction
The section below gives an overview of the mode of operation of the CPU display. Detailed information on the individual options, a training course and a simulation of the selectable menu items is available in the SIMATIC S7-1500 Display Simulator
( http://www.automation.siemens.com/salesmaterial-as/interactive-manuals/gettingstarted_simatic-s7-1500/disp_tool/start_en.html
).
Display
The S7-1500 CPU has a front cover with a display and operating keys. The display of the
CPU shows you the control and status information in different menus. You use operating keys to navigate through the menus and make a variety of settings in the process.
Benefits
The display of the CPU offers the following advantages:
● Reduced downtimes through diagnostic messages in plain text
● Changing of the interface settings locally without a programming device
● Password assignment for display operation is possible via STEP 7.
● Shorter downtimes due to read and write access to force tables and read access to watch tables:
The watch tables and force tables allow the current values of the individual tags of a user program or CPU to be monitored and modified on the display. You can find additional
● IP addresses of CPU and connected CMs/CPs can be set.
● For F-CPUs: Overview of status of safety mode and of F-parameters of F-CPU and F-I/O.
● Backing up/restoring the CPU configuration to/from the SIMATIC memory card.
Operating temperature for the display
To increase the service life of the display, the display switches off when the permitted operating temperature is exceeded. When the display has cooled down again, it switches on automatically again. When the display is switched off, the LEDs continue to show the status of the CPU.
Additional information about the temperatures at which the display switches off and back on again is available in the technical data of the manuals of the CPUs.

Introduction
Replacing an I/O module
● When the front connector is first inserted into the I/O module, a part of the coding element clips onto the front connector.
● In the case of fail-safe modules, the electronic coding element with the PROFIsafe address of the F-module also engages completely in the front connector.
When you replace an I/O module with the same type of module, the correct coding element or coding elements in the case of F-modules are already present in the front connector.
Result: Before inserting the previous front connector, you must remove the coding element(s) from the new I/O module.
Procedure
To replace the I/O module, follow these steps:
You have already uninstalled the I/O module.
You can find information on removing the I/O module in section Installing I/O modules
1.
For a new I/O module, use a screwdriver to break out the half of the mechanical coding element that is designated for the front connector.
Note
The arrangement of the mechanical coding element depends on the module type: Check the position of the coding element on the front connector before you break out the matching half from the I/O module.
For a new fail-safe module you must also remove the electronic coding element from the
F-module.

13.5 Reset to factory settings
Procedure using the mode selector
Make sure that the CPU is in STOP mode (the CPU display shows STOP mode or
RUN/STOP LED lights up yellow).
Note
Reset to factory settings ↔ Memory reset
The procedure described below also corresponds to the procedure for a memory reset:
•
Selector operation with inserted SIMATIC memory card: CPU executes a memory reset
•
Selector operation without inserted SIMATIC memory card: CPU executes reset to factory settings
Perform a reset to factory settings as follows:
1.
Set the mode selector to the STOP position.
Result: The RUN/STOP LED lights up yellow.
2.
Set the mode selector to the MRES position. Hold the mode selector in this position until the RUN/STOP LED lights up for the 2nd time and remains continuously lit (this takes three seconds). After this, release the selector.
3.
Within the next three seconds, switch the mode selector back to the MRES position, and then back to STOP again.
Result: The CPU executes a "Reset to factory settings", during which time the RUN/STOP
LED flashes yellow. When the RUN/STOP LED lights up yellow, then the CPU has been reset to factory settings, and is in the STOP mode. The "Reset to factory settings" event is entered into the diagnostics buffer.
Note
The IP address of the CPU is also deleted when the CPU is reset to the factory settings through the mode selector.
Procedure using the display

13.6 Fault reactions with fail-safe modules
Note
Substitute value behavior of the installed I/O modules during reset to factory settings
With "Reset to factory settings", the I/O modules in the station change to the non-configured state, which means that no input data is acquired and no output data is output.
Reference
You will find more information on the procedure in the STEP 7 online help.
13.6
Fault reactions with fail-safe modules
Safe state (safety concept)
The basic principle behind the safety concept is the existence of a safe state for all process variables.
Note
For fail-safe input and output modules, this safe state is the value "0".
Fault reactions and startup of the F-system
The safety function requires that substitute values (safe state) be output instead of process values for a fail-safe module (passivation of the fail-safe module) in the following cases:
● When the F-system is started up
● If errors are detected during safety-related communication between the F-CPU and the Fmodule via the PROFIsafe safety protocol (communication error)
● If F-I/O faults or channel faults are detected (e.g., wire break, discrepancy error)
Detected faults are written to the diagnostic buffer of the F-CPU and communicated to the safety program in the F-CPU.
F-modules cannot save errors as retentive data. When the system is powered down and then restarted, any faults still existing are detected again during startup. However, you have the option of saving faults in your safety program.
WARNING
Channel faults do not trigger any diagnostic reactions or error handling for channels that have been set to "deactivated" in STEP 7, even when this channel is affected indirectly by a channel group fault (Channel parameter "activated/deactivated").

System Manual, 09/2016, A5E03461182-AD

Maintenance
13.6 Fault reactions with fail-safe modules
Remedying faults in the F-system
To remedy faults in your F-system, follow the procedure described in IEC 61508-1:2010 section 7.15.2.4 and IEC 61508-2:2010 section 7.6.2.1 e.
The following steps must be performed:
1.
Diagnostic and repair of the fault
2.
Revalidation of the safety function
3.
Recording in the service report
Fail-safe value output for F-modules
In the case of F-modules with inputs, the F-system provides fail-safe values (0) for the safety program instead of the process data pending at the fail-safe inputs in case of passivation.
In the case of F-modules with outputs, the F-system transfers fail-safe values (0) to the failsafe outputs instead of the output values provided by the safety program in case of passivation. The output channels are de-energized. This also applies when the F-CPU goes into STOP mode. The parameter assignment of fail-safe values is not possible.
Depending on the F-system used and the type of fault that occurred, (F-I/O, channel or communication error) and on the parameter assignment of the F-module, fail-safe values are used either for the affected channel only or for all channels of the fail-safe module involved.
Reintegration of a fail-safe module
The system changes from fail-safe to process values (reintegration of an F-module) either automatically or only after user acknowledgment in the safety program. If channel faults occur, it may be necessary to remove and reinsert the F-module. A detailed listing of faults requiring removal and insertion of the F-module can be found in the section Diagnostic messages of the respective F-module.
After reintegration, the following occurs:
● In the case of an F-module with inputs, the process data pending at the fail-safe inputs are provided to the safety program
● In the case of an F-module with outputs, the output values provided in the safety program are again transferred to the fail-safe outputs
Additional information on passivation and reintegration
For additional information on passivation and reintegration of F-I/O, refer to the SIMATIC
Safety, Configuring and Programming
( http://support.automation.siemens.com/WW/view/en/54110126 ) manual.
Reaction of the F-module with inputs to communication errors
F-modules with inputs respond differently to communication errors compared to other errors.
If a communication error is detected, the current process values remain set at the inputs of the F-module. There is no passivation of the channels. The current process values are passivated in the F-CPU.

Introduction
Test functions
You have the option of testing the operation of your user program on the CPU. You can then monitor signal states and values of tags and can assign values to tags to simulate specific situations in the running of the program.
Note
Using test functions
The use of test functions can influence the program execution time and thus the cycle and response times of the controller to a slight extent (a few milliseconds).
Requirements
● There is an online connection to the relevant CPU.
● An executable user program is available in the CPU.
Test options
● Testing with program status
● Testing with a watch table
● Testing with a force table
● Testing with a PLC tag table
● Testing with a data block editor
● Testing with the LED flash test
● Testing with a trace function
Automation system
System Manual, 09/2016, A5E03461182-AD

Test functions and fault resolution
14.1 Test functions
Testing with program status
The program status allows you to monitor the execution of the program. You can display the values of operands and the results of logic operations (RLO) allowing you to recognize and fix logical errors in your program.
Note
Restrictions with the "Program status" function
The monitoring of loops can increase the cycle time significantly, depending in each case on the number of tags to be monitored and on the actual number of loops processed.
WARNING
Testing with program status
A test with the "Program status" function can cause serious damage to property or injury to persons if there are functional disturbances or program errors.
Make sure that no dangerous situations can arise before you conduct a test with the
"Program status" function.
226

Test functions and fault resolution
14.1 Test functions
Testing with watch tables
The following functions are available in the watch table:
● Monitoring of tags
You can use the watch tables to monitor the current values of the individual tags of a user program or a CPU on the programming device/PC, on the display of the CPU, and on the web server. A symbolic name for the tags must be specified in the "Name" column of the watch table to allow the display of the CPU and the web server to show the value of the tags.
You can monitor the following operand areas:
– Inputs and outputs (process image) and bit memory
– Contents of data blocks
– Peripheral inputs and peripheral outputs
– Timers and counters
● Modifying tags
Use this function to assign fixed values to the individual tags of a user program or CPU on the PG/PC. Modifying is also possible with Test with program status.
The following operand areas are modifiable:
– Inputs and outputs (process image) and bit memory
– Contents of data blocks
– Peripheral inputs and peripheral outputs (for example, %I0.0:P, %Q0.0:P)
– Timers and counters
● "Enable peripheral outputs" and "Modify now"
These two functions enable you to assign fixed values to individual peripheral outputs of a CPU in the STOP mode. You can also use them to check your wiring.
Automation system
System Manual, 09/2016, A5E03461182-AD
227
Test functions and fault resolution
14.1 Test functions
Testing with a force table
The following functions are available in the force table:
● Monitoring of tags
You can use the force tables to display the current values of the individual tags of a user program or a CPU on the programming device/PC, on the display of the CPU, and on the web server. You can monitor the table with or without trigger condition.
A symbolic name for the tags must be specified in the "Name" column of the force table in order that the display of the CPU and the web server can display the value of the tags.
You can monitor the following tags:
– Bit memory
– Contents of data blocks
– Peripheral inputs
● Modifying tags
You use this function to assign fixed values to individual tags of a user program or a CPU on the programming device/PC or on the display of the CPU. Modifying is also possible with Test with program status.
The following tags are modifiable:
– Bit memory
– Contents of data blocks
– Peripheral inputs (e.g. %I0.0:P)
● Forcing of peripheral inputs and peripheral outputs
You can force individual peripheral inputs or peripheral outputs.
– Peripheral inputs: Forcing of peripheral inputs (for example %I0.0:P) is a "bypassing" of sensors / inputs by the specification of fixed values to the program. The program receives the force value instead of the actual input value (via process image or via direct access).
– Peripheral outputs: Forcing of peripheral outputs (for example %Q0.0:P) is a
"bypassing" of the complete program by the specification of fixed values to the actuators.
One advantage of the force table is that you can simulate different test environments and overwrite tags in the CPU with a permanent value. This enables you to intervene in the ongoing process for regulating purposes.
Difference between modifying and forcing
The fundamental difference between the modifying and forcing functions consists in the storage behavior:
● Modifying: Modifying of tags is an online function and is not stored in the CPU. You can end modifying of tags in the watch table or force table or by terminating the online connection.
● Forcing: A force job is written to the SIMATIC memory card and is retained after a
POWER OFF. The S7-1500 CPU displays an active force job with a corresponding symbol. You can only end the forcing of peripheral inputs and peripheral outputs in the force table.

Test functions and fault resolution
14.1 Test functions
Testing with a PLC tag table
You can monitor the current data values of tags in the CPU directly in the PLC tag table. To do so, open the PLC tag table and start the monitoring.
You also have the option of copying PLC tags to a watch table or force table so that you can monitor, control or force them in the table.
Testing with a data block editor
The data block editor offers different options for monitoring and modifying tags. These functions directly access the actual values of the tags in the online program. Actual values are the current values of tags in the CPU work memory at any moment during program execution. The following functions for monitoring and modifying are available in the database editor.
● Monitor tags online
● Modify individual actual values
● Create a snapshot of the actual values
● Overwrite actual values with a snapshot
Note
Setting data values during commissioning
During commissioning of a plant, data values have to be frequently adjusted in order to optimally adapt the program to the general operating conditions on site. The declaration table for data blocks offers some functions for this purpose.
Testing with the LED flash test
In many online dialogs, you can perform an LED flash test. This function is useful, for example, when you are not sure which device in the hardware configuration corresponds to the station currently selected in the software.
When you click the "Flash LED" button, an LED flashes at the currently selected station. On the CPU, the following LEDs flash: RUN/STOP LED, ERROR LED and MAINT LED. The
LEDs flash until you cancel the flash test.
Testing with a trace function
The trace function is used to record the CPU tags, depending on the settable trigger conditions. Tags are, for example, drive parameters or system and user tags of a CPU. The
CPU saves the recordings. You can display and evaluate the recordings, if necessary, with
STEP 7 or via the Web server.
The trace function can be called from the CPU's folder in the project tree, under the name
"Traces".
In connection with trace functions, also note the following FAQ on the Internet

Procedure using STEP 7
A description of how to save service data is available under the keyword "Save service data" in STEP 7 online help.
Procedure via the SIMATIC memory card
Use the SIMATIC memory card to read out the service data only if you are no longer able to communicate with the CPU via Ethernet. In all other cases it is preferable to read out the service data via the Web server or STEP 7.
The procedure using the SIMATIC memory card is more time-consuming than the other options for reading out the service data. You must also ensure before reading out that there is sufficient memory space on the SIMATIC memory card.
To read service data using the SIMATIC memory card, follow these steps:
1.
Insert the SIMATIC memory card into the card reader of your PC / programming device.
2.
Open the job file S7_JOB.S7S in an editor.
3.
Overwrite the entry PROGRAM with the string DUMP in the editor.
To ensure that the file size is exactly 4 bytes, do not use any spaces/line breaks/quotation marks.
4.
Save the file under the existing file name.

In the case of surges according to IEC 61000-4-5:2014, the S7-1500/ET 200MP fail-safe
I/O modules without external protective circuit fulfil severity level 2.
Protecting S7-1500/ET 200MP against overvoltages with fail-safe modules
If your system requires protection from overvoltage, we recommend that you use an external protective circuit (surge filter) between the load current supply and the supply voltage input of the F-modules to ensure surge immunity for S7-1500/ET 200MP with fail-safe modules.
Note
Lightning protection measures always require a case-by-case examination of the entire system. An almost complete protection from overvoltages, however, can only be achieved if the entire building surroundings have been designed for overvoltage protection. In particular, this involves structural measures in the building design phase.
For detailed information regarding overvoltage protection, we recommend that you contact your Siemens representative or a company specializing in lightning protection.
You can find more information on protection from overvoltage in the Designing interferencefree controllers ( http://support.automation.siemens.com/WW/view/en/59193566 ) function manual.

Glossary
Automation system
Programmable logic controller for the closed-loop and open-loop control of process chains in the process engineering industry and manufacturing technology. The automation system consists of different components and integrated system functions according to the automation task.
Baud rate
Data transmission rate indicates the number of bits transmitted per second (baud rate = bit rate).
Bit memory
Bit memory is a component of the system memory of the CPU for saving intermediate results. It can be accessed in bit, byte, word or double word mode.
Bus
A common transfer route to which all nodes of a field bus system are connected; it has two defined ends.
Bus cable connector
Physical connection between the bus node and the bus cable.
Bus, self-assembling
The modules are lined up on the mounting rail, and are mechanically and electrically connected to each other with a U connector as they are swiveled into position. In this way the bus is extended with each module.
Code block
In SIMATIC S7, a code block is a block that contains a section of the STEP 7 user program.
(in contrast to a data block, which contains only data)
Configuration
Systematic arrangement of the individual modules (configuration).
Automation system
System Manual, 09/2016, A5E03461182-AD
Connection plug
Physical connection between device and cable.
Glossary
Consistent data
Data whose content belongs together and must not be separated is known as consistent data.
Counter
Counters are components of the system memory of the CPU. You can modify the content of the "counter cells" using STEP 7 instructions (e.g. count up/down).
CPU
The CPU uses the integrated system power supply to supply the electronics of the modules via the backplane bus. The CPU contains the operating system and executes the user program. The user program is located on the SIMATICmemory card and is processed in the work memory of the CPU. The PROFINET interfaces on the CPU allow simultaneous communication with PROFINET devices, PROFINET controllers, HMI devices, programming devices, other controllers and other systems. The S7-1500 CPUs support operation as an IO controller and I-device. Similarly to the PROFINET interface, the PROFIBUS interface available on some of the S7-1500 CPUs allows communication with other devices. When the interface is used as PROFIBUS DP interface, the CPU on the PROFIBUS DP also assumes the role of a DP master.
Crimping
Procedure whereby two components joined together, e.g. wire end sleeve and cable, are connected with one another through plastic strain.
Cycle time
The cycle time represents the time a CPU requires to execute the user program once.
Cyclic interrupt
see "Interrupt, cyclic"
Data block
Data blocks (DBs) are data areas in the user program that contain user data. There are global data blocks, which can be accessed from all code blocks, and instance data blocks, which are assigned to a specific FB call.
Device
A device can send, receive or amplify data via the bus, e.g. IO device via PROFINET IO.

Glossary
Device names
Before an IO device can be addressed by an IO controller, it must have a device name. This approach was chosen for PROFINET because names are easier to administer than complex
IP addresses.
In its delivery state, an IO device has no device name. An IO device can only be addressed by an IO controller - e.g., for transferring configuration data (including the IP address) during startup, or for user data exchange during cyclic operation - after it has been assigned a device name with the programming device/PC.
Diagnostic buffer
The diagnostic buffer is a battery-backed memory area in the CPU where diagnostic events are stored in their order of occurrence.
Diagnostics
Monitoring functions for the detection, localization, classification, display, and further evaluation of errors, faults, and alarms. They run automatically while the system is in operation. This increases the availability of systems by reducing commissioning times and downtimes.
Diagnostics interrupt
see "Interrupt, diagnostic"
Distributed I/O system

Function
Glossary
A function (FC) is a code block with no static data. A function allows you to pass parameters in the user program. Functions are thus suited for programming frequently recurring complex functions, such as calculations.
Function block
A function block (FB) is a code block with static data. An FB allows you to pass parameters in the user program. Function blocks are thus suited for programming frequently recurring complex functions, such as closed-loop controls or operating mode selection.

Glossary
Identification data
Information that is saved in modules, and that supports the user in reviewing the system configuration and locating hardware changes.
Instance data block
Each call of a function block in the STEP 7 user program is assigned a data block, which is automatically generated. Values of the input, output and in/out parameters, as well as local block data, are stored in the instance data block.
Interface module
Module in the distributed I/O system. The interface module connects the distributed I/O system to the CPU (IO controller) via a fieldbus, and prepares the data for and from I/O modules.
Interrupt
The operating system of the CPU distinguishes between various priority classes that control the execution of the user program. These priority classes include interrupts, such as hardware interrupts. When an interrupt occurs, the operating system automatically calls an assigned organization block. The user can program the desired reaction in the organization block (e.g. in a FB).
Interrupt, cyclic
The CPU generates a cyclic interrupt periodically within a parameterizable time grid and then processes the corresponding organization block.
Interrupt, hardware
A hardware interrupt is triggered by interrupt-triggering modules due to a certain event in the process. The hardware interrupt is signaled to the CPU. The CPU then processes the assigned organization block according to the priority of this interrupt.
Interrupt, time-delay
The time-delay interrupt is one of the program execution priority classes of SIMATIC S7. It is generated after expiration of a timer started in the user program. The CPU then processes the corresponding organization block.
Interrupt, time-of-day
The time-of-day interrupt is one of the program execution priority classes of SIMATIC S7.. It is generated based on a defined date (or daily) and time (e.g. 9:50 or every hour, every minute). The CPU then processes the corresponding organization block.

Glossary
Interrupt, update
When it receives an update interrupt, the operating system calls the update interrupt OB.
This may happen if you changed a parameter on a slot of a device.
IP address
The IP address is made up of four decimal numbers with a range of values from 0 through
255. The decimal numbers are separated by a dot (e.g. 192.162.0.0).
The IP address consists of the following:
● Address of the network
● Address of the device (PROFINET interface of the IO controller/IO device)
Isolated modules
In the case of isolated input/output modules, the reference potentials of the control and load circuits are galvanically isolated, e.g. by means of optical isolators, relays or transformers.
Input/output circuits can be connected to common potential.
Load current supply
Supply of the module's input and output electric circuits.
MAC address
Every PROFINET device is assigned a worldwide unique device identification before it leaves the factory. This 6-byte long device identification is the MAC address.
The MAC address is divided into:
● 3-byte manufacturer identification
● 3-byte device identification (consecutive number)
The MAC address is generally shown on the front of the device.
Example: 08-00-06-6B-80-C0
Non-isolated modules
In the case of non-isolated input and output modules, the reference potentials of the control and load circuits are electrically connected.
NTP
The Network Time Protocol (NTP) is a standard for synchronizing clocks in automation systems via Industrial Ethernet. NTP uses the UDP connectionless network protocol.

Glossary
Organization block
Organization blocks (OBs) form the interface between the operating system of the CPU and the user program. The organization blocks determine the order in which the user program is executed.
Parameter
● Tag of a STEP 7 code block:
● Tag for setting the behavior of a module (one or more per module). In as-delivered state, every module has an appropriate basic setting, which you can change by configuring in
STEP 7. There are static and dynamic parameters
Parameter assignment
Parameter assignment is the transfer of parameters from the IO controller / DP master to the
IO device / DP slave.
Parameters, dynamic
In contrast to static parameters, you can change dynamic parameters of modules during operation by calling an SFC in the user program, e.g. limit values of an analog input module.
Parameters, static
In contrast to dynamic parameters, you cannot change static parameters of modules with the user program but only by configuring in STEP 7, e.g. input delay of a digital input module.
PELV
Protective Extra Low Voltage = grounded extra low voltage with safe isolation
Pre-wiring
Wiring of the electrical system on the front connector before the front connector is used on the I/O module.
Process image (I/O)
The CPU transfers the values from the input and output modules to this memory area. At the start of the cyclic program the signal states of the input modules are transmitted to the process image of the inputs. At the end of the cyclic program the process image of the outputs is transmitted as signal state to the output modules.
Product version (PV) = Function version (FV)
The product version or function version provides information on the hardware version of the module.

PROFIBUS and industrial Ethernet. A cross-manufacturer communication, automation, and engineering model defined by PROFIBUS International e.V. as an automation standard.
PROFINET IO
Communication concept for the realization of modular, distributed applications within the scope of PROFINET.
PROFINET IO controller
Device used to address connected I/O devices (e.g. distributed I/O systems). This means that: The IO controller exchanges input and output signals with assigned I/O devices. Often, the IO controller is the CPU on which the automation program runs.
PROFINET IO device
Distributed field device that can be assigned to one or more IO controllers (e.g. distributed
I/O system, valve terminals, frequency converters, switches).
Push-in terminal
Terminal for the tool-free connection of wires.
Reference potential
Potential from which the voltages of the circuits involved are observed and/or measured.
Restart
During a warm restart, all non-retentive bit memory is deleted and non-retentive DB contents are reset to the initial values from load memory. Retentive bit memory and retentive DB contents are retained. Program execution begins at the call of the first startup OB.
Retentivity
A memory area whose content is retained after power failure and after a STOP to RUN transition is retentive. The non-retentive area of the bit memory, timers and counters is reset after power failure and after a STOP to RUN transition.

Slave station
A slave may only exchange data with a master after being requested to by the master.
SNMP
SNMP (Simple Network Management Protocol) is the standardized protocol for performing diagnostics on and assigning parameters to the Ethernet network infrastructure.
In the office setting and in automation engineering, devices from a wide range of vendors on the Ethernet support SNMP.
SNMP-based applications can be operated on the same network in parallel to applications with PROFINET.
The scope of supported functions varies depending on the device type. For example a switch has more functions than a CP 1616.
Switch
PROFIBUS is a linear network. The communication nodes are linked by means of a passive cable - the bus.
By contrast, Industrial Ethernet consists of point-to-point connections: each communication node is interconnected directly with precisely one other communication node.
If a communication node is linked to several communication nodes, this communication node is connected to the port of an active network component - the switch. Additional communication nodes (including switches) can now be connected to the other ports of the switch. The connection between a communication node and the switch remains a point-topoint connection.
A switch thus has the task of regenerating and distributing received signals. The switch
"learns" the Ethernet address(es) of a connected PROFINET device or additional switches and only forwards those signals that are intended for the connected PROFINET device or switch.
A switch has a specific number of connections (ports). You connect at most one PROFINET device or additional switch to each port.
