System event from connectivity server saying "Refresh is needed"

Hello,

After a download to a 800M safety controller in our 800xA v5.1 FP4 system, we got a system event with object name "<IP address of connectivity server>:22-_SWAlarmEvent" and message "Refresh is needed".

An IAC communication variable had been removed. Am I correct to assume that the event is caused by the removal of the IAC variable, and that the event is merely a notification that the OPC server refreshes the clients? No further action is neccessary I guess?

Thanks,

Tor Anders

This event is custom made to trigger the 800xA HMI to pull a refresh of the OPC AE server.

Eg if you download a delete of a block currently in alarm state; without this special event, the deleted object's alarm would linger and reject acknowledgement, etc.
