Installing fail-safe signal modules
The fail-safe signal modules belong to the S7-300 family and support central operation in S7-
300 and distributed operation in the ET 200M Distributed I/O Device.
The fail-safe signal modules are installed in an S7-300 or ET 200M similar to any other S7-
300 signal module.
For further information, refer to the
S7-300, CPU 31xC and CPU 31x: Installation
installation manual, or to the
ET 200M Distributed I/O Device manual.
Redundant configuration of ET 200M
Note
All redundant systems with integrated ET 200M
must be installed in a control cabinet which
provides adequate attenuation functions for limiting RF interference (see chapter
"Electromagnetic Compatibility (Page 62)").
This is
not necessary whe
n you use an IM153-2 as of 6ES7153-2BA02-0XB0.
