The electronics modules of the SIMATIC ET 200iSP distributed I/O system equipped with safety functions can be used together with the safety-related automation systems of the SIMATIC PCS 7 process control system for the implementation of safety applications. The input modules record the process signals, evaluate them, and prepare them for addional processing by the automation system. The output modules convert the safety-related signals output by the automation systems so that they are suitable for controlling the connected actuators.

- The safety-related electronics modules are installed on terminal modules which must be additionally ordered.
- The safety-related electronics modules are plugged as planned onto terminal modules using screw-type systems (TM‑EM/EM60S) or spring-loaded systems (TM‑EM/EM60C).
- Using a spare module plugged onto a terminal module TM‑EM/EM60S or TM‑EM/EM60C, you can reserve a slot for an safety-related electronics module or close a gap resulting from the design. The spare module can be simply replaced by the envisaged electronics module at a later point in time.
- The mechanical coding of the terminal module which is carried out when an electronics module is plugged on for the first time prevents the connection of incorrect replacement modules.
- Hot swapping of individual modules is possible under hazardous conditions.
- The process signals are connected to the terminals of the terminal modules assigned according to the plan, using either conventional screw-type or spring-loaded systems (conductor cross-sections 0.14 mm² to max. 2.5 mm²) depending on the type of module.
