Dear All,

I am working on S7-400 redundancy project. We have S7-400(412-5H) redundant CPU.

We have following configuration

IM 1-  IM153-2HF with 1  AO module, 2 AI modules, 5 DI modules and 2 DO modules

IM 2- IM153- 2HF with 1 AO module, 1 AI module

Is it possible to obtain redundancy between First AO module of IM1 and First AO module of IM2 and second AI module of IM1 and second AI module of IM2.

Thanks For Support,

Regards,

Maddy

Hi PSW2586,

I want to know redundancy is possible only if we have same no. of modules in Both IM and same configuration. As attached hardware config I want to make redundancy between first two modules of IM only. other modules fron IM (Profibus address 3) are non redundant.

Pls Help.

Regards,

maddy
