Cause

The specification of the station name is missing at a 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

1. 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.
2. Open the property dialog of the PLC box.
3. Bring the PLC structure data tab to the front.
4. Assign a corresponding name in the Station ID field or select an entry from the drop-down list.
5. Click [OK].
6. Then start a new check run.
