Redundant configuration of CI840 with Siemens H System
How to configure CI840 in Siemens H System?
We are using TU847 with two CI840A as redundant slaves with Siemens H System.
We are trying to use ABB_0630_v413 GSD which is available in download center but unable to configure it in Step-7 in redundant configuration.
Can you please help in getting configuration manual or right GSD file?
I'm not quite sure if it is possible to connect CI840 to redundant Siemens H system.
CI840 is used to connect IO modules from S800IO type to CI854 Profibus DP communication processor.
CI854A could be only master, so you can connect a slaves to it.
So may be you need a GSD file from Simatic, which to integrate to your system by GSD Import.
About redundancy in this case, I'm not quite sure, in a way you describe. May be you could use RLM01 to make 2 profibus lines in one. But without redundancy from Simatic side.
I look at google for abb CI840 gsd - there are different issues, some of them:
