Cause

Possibility 1

A device that has function templates was placed in the schematic. At least two function templates belong to the same category (e.g. "Electrical engineering: Terminals"), have identical connection point designations, and their properties Subordinate DT / DT ID, Terminal / Pin designation and / or PLC subdevice: Index have identical values.

Possibility 2

A new device that disposes of function templates was created y in the device navigator. At least two function templates belong to the same category (e.g. "Electrical engineering: Terminals"), have identical connection point designations, and their properties Subordinate DT / DT ID, Terminal / Pin designation and / or PLC subdevice: Index have identical values.

Solution

1. Open the device navigator.
2. Locate the device in the device navigator for both possibilities by means of the functionality Synchronize selection.
3. Open the properties of the device and identify the associated part in the part selection by using the Parts tab.
4. In the Function templates tab compare for each function template the values of the properties Connection point designations, Subordinate DT / DT ID, Terminal / Pin designation and - in case of PLC connection points - in addition the property PLC subdevice: Index, and note them.
5. Close the part selection and the property dialog, and call up the parts management (Tab Master data > Command group Parts > Management).
6. In the tree view, go to the part identified and select it.
7. Bring the Function templates tab to the front and change the connection point designations that appear more than once on the function templates, so that each function template has a unique connection point designation.
8. Assign different values for at least one of the properties Subordinate DT / DT ID, Terminal / Pin designation and / or PLC subdevice: Index. at the function templates.
9. Close the parts management and confirm all the messages that follow by clicking [Yes].
10. If required, start a new check run.
