Description
You cannot make a cross-reference between a PLC connection point in the schematic and a PLC connection point on the overview page.
Cause
A PLC connection point in the schematic cannot be cross-referenced with the corresponding PLC connection point because of a missing device tag in the PLC box in the overview.
Solution
Enter the same DT at the PLC connection point in the PLC box in the schematic and in the PLC box in the overview, and start a new check run.
