Cause
You use the PLC import interface Beckhoff TwinCat: No bus port (output) was found for a bus port (input) at the device <x> named in the message during importing. The matching bus port (output) is always searched for at the predecessor address <y>.
Solution
- Check whether a bus port (output) exists for the bus port (input) of the device <x> named in the message at the predecessor address <y>.
- Import the PLC data again.
Note:
Using a new check run (any desired scheme) this module-specific message can be deleted from the message management dialog.
