CI854 and siemens s7-300 comm problem.
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?
