Fail-safe signal modules

F digital/analog modules

Description

The fail-safe signal modules of ET 200M are the interface between the fail-safe SIMATIC PLCs and the process. A host of different digital and analog modules provide exactly the inputs/outputs required for each task.

Application

The spectrum of fail-safe input and output modules is used for central expansion of the SIMATIC S7-300F or for distributed expansion in an ET 200M station for fail-safe S7 PLCs.

For distributed expansion of a SIMATIC S7-400FH, the ET 200M I/O also supports a redundant configuration.
In combination with the redundant PROFIBUS interface, this forms the basis of Flexible Modular Redundancy™ (FMR): The fault tolerance level can be tailored to requirements in that single, two and three-channel redundancies can be combined in the same system and tuned to each other. The redundant architecture offers maximum availability since this measure can compensate for failure of a CPU, a PROFIBUS line or a signal module. In addition, safety-related and standard I/O modules (critical and non-critical I/Os) can be combined in an ET 200 M/S station.

Benefits

Space-saving assembly due to the high packing density of channels
Easy parameterization in STEP 7
Fail-safe and standard modules can be combined
One bus (PROFIBUS DP) for the transmission of fail-safe and standard signals
Flexible Modular Redundancy™ (FMR): Maximum flexibility during selection of redundancy level – matching the Safety Instrumented Function (SIF)
