VASS driver do not support no messages

VASS driver do not support no messages

Description

When the PLC sends an empty message-telegram (without alarms) the last active alarm cannot be removed from the alarm message list. 

It will continue to be displayed even if it has already been removed in the PLC. Only a restart clears the alarm message list completely.

This behavior has been changed. Removing alarms now also works for the last remaining alarm in the list.

To benefit from this fix:

  • Update your zenon Software Platform to the latest build of zenon 8.20 or higher.
