The IEC 61850 Server fieldbus driver returned a positive response to a SetURCBValues service request despite a lack of reservation (Resv = False) for this client, because it did not check the validity when the current value already was the same as requested.

The issue has been addressed and the behavior is now as expected. 

To benefit from this fix:

• Update your zenon Software Platform to the latest build of zenon 16 or higher.
