Cause
The information that a PLC box is a CPU is missing at the PLC box. This information is required for a correct PLC data export from EPLAN.
This check run only checks PLC boxes which are main functions and at which a configuration project is entered.
Solution
- Locate the PLC box in the schematic using the Go to (graphic) functionality that is provided by the popup menu of the Message management dialog.
- Open the property dialog of the PLC box.
- Bring the PLC structure data tab to the front.
- Activate the CPU check box in the properties list.
- Ensure that a configuration project and a station ID are entered at the PLC box.
- Click [OK].
- Then start a new check run.
Note:
Take into account that a CPU does not have to exist at every workstation. It is sufficient if at least one CPU exists under all workstations that are assigned to a configuration project.
