T5BusExopcua_s: writing a string variable from an OPC UA client takes over the value the first time but not on subsequent writes

Description

If an OPC UA client writes a value of a READ/WRITE string variable to the zenon Logic Service, the value is only written at the first write operation. In subsequent write operations the value is no longer taken over.

This error has been fixed. The value is now taken over with every write operation.

To benefit from this fix:

  • Update your zenon Software Platform to the latest build of zenon 11 or higher.
