Dear All,

In one of my project I have 400H with IO redundancy. I want to use block for IO redundancy. I found following three Libaries for IO redundnacy
1.Redundant IO CGP V40
2.Redundant IO CGP V52
3.Redundant IO MGP V32

In sample project I foundZXX01_15_HSystem_RED_IOproject but block version is different with libaries.

So I am confuse which block we need to use for IO redundancy ?

I am using Step7 5.5 SP3 for development.

Waiting for reply.

Regrads,

Yogendra

Signal modules as redundant I/O

The signal modules listed below can be used as redundant I/O. Refer to the latest information about the use of modules available in the readme file and in the SIMATIC FAQ at http://www.siemens.com/automation/service&support under the keyword "Redundant I/O".

Take into account that you can only use modules of the same product version and same firmware version as redundant pairs.
