Answer question

Slow Alarms

The system is 800xA 5.1 Rev A with 2 AS and 4 CS (2 redundant pairs). The connectivity is Advant Master. The (physical one) MB300 is virtual divided into 2 networks, the event filtering is set with NODE_DESCR elements.

I have the problem that all OPC-DA subsciptions are really fast but the alarms/events (as OPC A&E) are delayed for up to 20 seconds.

That means, I set an alarm state, I see in that moment it happens in graphic elements but for the alarm list it takes some time. The same behavior if I quit that alarm.

I have restarted all connectivity server and the Alarm Managers. All services are "green", the affinity is set like the manual says.

Any idea? Thank you in advance!
