Configuration of Redundant I/O Modules in SIMATIC PCS 7

  • Entry
  • Associated product(s)
In principle, the high availability in PCS 7 can be used at all levels. With SIMATIC ET 200M modules, the distributed I/O can also be designed as redundant.

In this documentation the emphasis is placed on the application of redundant distributed I/O using ET 200M modules. Thereby, particularly the wiring options of the input/output modules as well as the individual configuration steps are explained.

Main contents
The document focuses on the following points:

  • Redundant I/O modules especially with channel granular functionality
  • Setup, wiring and configuration of redundant ET 200M stations
  • Using Marshalled Termination Assemblies (MTA) as an interface between the distributed I/O modules and the acutators or sensors
  • Diagnostics options on a fault-tolerant system with redundant I/Os in case of an error

This entry was created with SIMATIC PCS 7 V7.0 and V8.1, the procedure is valid for PCS 7 V7.0 and higher versions.
