Cause
Possibility 1
You have inserted a device with distributed functions in the schematic or created the device in the device navigator. This means at least two function are using the same connection point designation.
Example:You have inserted a contactor consisting of a contactor coil and two NO contacts into the schematic. The same connection point designation 13¶14 .was erroneously assigned to both NO contacts.
Possibility 2
You have placed a function in the schematic or created it in the device navigator and have assigned one or more identical connection point designations.
You have created a single-phase transformer with two windings in the device navigator. The connection point designation was accidentally changed from 1¶3¶2¶4 to 1¶3¶4¶4.
Solution
Regarding option 1
Starting from the Message management dialog use the menu items Go to (graphic) or Go to (cross-referenced) to locate the functions occurring distributed in the schematic or device navigator. For every found function call up the Properties <...> dialog and compare the values respectively entered in the Connection point designations field. Assign a unique connection point designation to every function.
In the case of bus ports the bus interface name is used for identification in addition to the plug designation.
Regarding option 2
Starting from the Message management dialog use the menu items Go to (graphic) or Go to (cross-referenced) to locate the functions in the schematic or device navigator. For the found function call up the Properties <...> dialog and note the entered values in the Connection point designations field. Assign a unique connection point designation to the function.
Then start a new check run.
Note:
In the case of bus ports the Plug designation and the Bus interface name are used for identification in addition to the connection point designation. A check is carried out whether this combination (Connection point designation + Plug designation + Bus interface name) is identical. If at least one of these partial designations shows a difference, the message is not output.
