hi. im looking for redundant system and redundant IO modules. I see that PCS7 with et-200SP HA only have redundancy for IO modules. Also, S7-1500 with et-200MP and with use of some library we can have redundant Io with S7-1500 with et-200sp.

My question is can we use redundant S7-1500 cpu with ET-200SP HA red IO modules or ET-200SP or ET-200MP.

Need clarity.

regrads.

Split from Do S7-1500 have redundancy in each component and redundancy with more than one PLC?.
