Cause
An address was assigned multiple times within a CPU.
Solution
- Change the addresses of the affected PLC connection points by means of the Properties <...> dialog so that each address within a CPU is uniquely addressed. (Assign the CPUs to a PLC box by setting the CPU and CPU: Name properties).
- If required, start a new check run.
Note:
This check run is also output when multiple addressed PLC connection points are not assigned to any CPU.
