Configuration of the SIMATIC S7-1500 Automation System


Configuration

​The SIMATIC ​S7‑1500​ automation system is made up of the following components:

·​CPU (standard, fail-safe, compact or technology CPU)

·​Digital and analog I/O modules

·​Communications modules (PROFINET/Ethernet, PROFIBUS, point-to-point)

·​Technology modules (counting, position detection, time-based IO)

·​Load current supply

·​System power supply (optional)

​You install the ​S7‑1500​ automation system on a mounting rail. You can install up to 32 modules (CPU, system power supply and 30 I/O modules) on the mounting rail. You connect the modules to each other with U connectors.

Configuration example



​① ​System power supply

​② ​CPU

​③ ​I/O modules

​④ ​Mounting rail with integrated DIN rail profile

Configuration of the distributed I/O system SIMATIC ET 200MP


Configuration

​The SIMATIC ​ET 200MP​ distributed I/O system is made up of the following components:

·​Interface module (PROFINET or PROFIBUS)

·​Digital and analog I/O modules

·​Communications modules (point-to-point)

·​Technology modules (counting, position detection, time-based IO)

·​System power supply (optional)

​The ​ ET 200MP​ distributed I/O system is installed on a mounting rail like the ​S7-1500​ automation system. ​The I/O modules of the SIMATIC ET 200MP distributed I/O system can be used in a decentralized configuration (with an ET 200MP interface module) or in a centralized configuration (with an S7-1500 CPU).

Hardware and software requirements


​You use the ​S7‑1500​/​ET 200MP ​fail-safe I/O modules:

·​In ​S7‑1500 ​with ​S7‑1500​ F-CPUs as of firmware version V1.7

·​Distributed in ​ET 200MP ​with ​S7‑1500​ F-CPUs as of firmware version V1.5 and all F-CPUs that can be selected in the hardware catalog of the TIA Portal

​Fail-safe I/O modules in ​ET 200MP ​ require the following interface modules:

·​IM 155-5 PN BA, as of firmware version V4.3

·​IM 155-5 PN ST, as of firmware version V3.0.0

·​IM 155-5 PN HF, as of firmware version V3.0.0

·​IM 155-5 DP ST, as of firmware version V3.0.0

​To configure and program fail-safe I/O modules ​S7‑1500​/​ET 200MP ​, you need:

·​STEP 7​, V13 SP1 or higher

·​The option package ​STEP 7 Safety Advanced​ as of V13 SP1 + HSP0086

Use in safety mode only

​You can only use the​ S7‑1500​/​ET 200MP ​fail-safe I/O modules in safety mode. They cannot be used in non-fail-safe mode, i.e. standard mode.

Achievable safety classes

​Fail-safe I/O modules are equipped with integrated safety functions for safety mode.

​You can achieve the safety classes of the table below:

·​By corresponding parameter assignment of the safety functions in ​STEP 7

·​With a specific combination of fail-safe and non-fail-safe I/O modules as well as

·​With a special arrangement and wiring of the sensors and actuators

Safety classes that can be achieved with S7‑1500/ET 200MP in safety mode

​Safety class in safety mode

​According to IEC 61508:2010 = Category 3 = SIL3

​According to ISO ​13849‑1:2015 ​(PL) = Category 3 = Performance Level d

​According to IEC 61508:2010 = Category 4 = SIL3

​According to ISO ​13849‑1:2015 ​(PL) = Category 4 = Performance Level de



Additional information

​An overview of the technical specifications of the fail-safe I/O modules can be found in section ​Fail-safe digital modules​.

​The applications and wiring for the particular safety class are described in the manuals of the fail-safe I/O modules
