CI854 and siemens s7-300 comm problem.
Hi, everybody.
I'm new in ABB AC800M plc. and i have problem with profibus communication between CI854 and s7-300.
I read latched Errors and warning bit it says (16#400) Device failure. And there is not any fault lamp. I check The s7-300 side plc there is ok.
I haven't new CI854 module. so i cannot try to change.
Is it problem with device or some config files or program are missing?

Hi,
Communication to Seimens device from ABB modules should be byte swapped via profibus.
Make sure the bytes are swapped then the communication will be done.

You need to use a DP-DP coupler to do that, you just need to import the GSD file of the DP/DP coupler and download hardware in both sides.
You need to swap bytes, because in one side you have CPU motorola and the other uses CPU intel.
