Redundant IO's with hot swapping function for S7-1500 R/H System

Dear Experts,

I want to design a redundant system using S7-1500 R/H system. In my system i need analog and digital redundancy with hot swapping function because i have some redundant IO's.So which IO system i have to use like ET200MP/ ET 200sp /ET200M or others Please suggest.

Also i want to know about the MTAs for AI or AO can be used with this system?

Thanks in advance.

Hello Kashir;

It appears the features you are looking for are part of the S7-400H systems, and are not yet available in the S7-1500 RH PLCs.

See this presentation of the S7-1500 RH system:

https://assets.new.siemens.com/siemens/assets/public.1562856005.8ad3e246-011b-4206-aa85-1ec60aac51ac.simatic-s7-1500-redundant-systems--techslides-2018-11-12-en.pdf

Compare with this manual for the S7-400H, especially the section Using I/Os in the S7-400H:

SIMATIC Fault-tolerant systems S7-400H (V6.0)

https://support.industry.siemens.com/cs/ww/en/view/82478488

And this document shows the use of MTAs (Marshalled terminaltion assemblies) with the S7-400H (I do not remember having seens any MTA for the S7-1500 family):

Hope this helps,
