CI840A Profibus slave 'parameter error on slave' ?
I am using AC900F with control builder F Ver10.1.
I am having trouble communicating with my CI840A via profibus.
The error message shown in my hardware structure is 'parameter error on slave'.
Has anyone having this issue before?

I assume you have not touched/changed any default parameterisation/configuration of profibus slave as well as master.
Check attached image, change module position to 0 instead of 1 for DI828 should solve your issue. So after changing to 0 save configuration. make full download to controller and then check.
So once you get resolved with parameter error, check on CI840A module R(RUN) light gets green and then perform SCAN bus from cbf(right click at profibus master icon at irght hand side pen of hw tree) you should get address 12 in operation mode. Means you are with healthy communication.
Secondly the way you configured hardware i.e you are using CI840 gsd and using CI840A hardware that too in redundant TU using single module. Principally this should works but it's not good recommended way, use both the modules and proper configurations.
Good luck! pls revert back incase of not resolved.
