Cause
Within a configuration project that contains multiple CPUs, a PLC card exists with a start address that cannot be assigned to any of the CPUs since no CPU name was assigned.
Solution
- Locate the PLC box of the PLC card in the schematic by using the Go to (graphic) functionality that is provided by the popup menu of the Message management dialog.
- Call up the property dialog of the PLC box and bring the Structure data tab to the front.
- In the property table for the CPU: Name [1] property select the name of the CPU in the configuration project to which you want to assign the PLC card.
- Click [OK].
- If required, start a new check run.
