P004013: Rack '<x>': Ring connection

Cause

The rack name and the specification of the rack name for the PLC card slot reference one another for two different PLC boxes.

This check run only checks PLC boxes at which a configuration project is entered.

Solution

Change the bus data in the Properties <...> dialog for both PLC boxes so that the rack names do not link up.

Then start a new check run.
