OPC tag not updating
I am using S+ operation 2.0.4. with redundent servers. I have 1 OPC data point from a kepware server that is not updaitng on the graphic on server1, but it does update on server2. The other data points from the same Kepware server are updating. If I view the point from the operatoring parameters the value is updating, but it does not update on the graphic.
This tag has been in the database for over a year and has worked in the past.

Possibly an issue with redundancy and failover ? What happens if you fail one of the Kepware OPC Service providers to force a failover ?
Hi,
I suspect may be the firewall is blocking the communication between server1 and kepware server.
Thanks to those who had suggestions. The tag just started working again.
It might be a network issue?
