Seamless trend not working on some of the servers
we have a problem with the SEAMLESS trending on some of the stations.
We have 1 system with 2 Domain Servers, 2 Aspect Servers and 2 AC800M Connectivity Servers (all redundant), 2 Connectivity Serves for QCS with AC800M (one for each machine) and 800xA History Server, History Archive and Operator / Engineering Stations. All running with the system 800xa 5.1 Rev E.
If I open the configured trends on one of the QCS servers the status of the data is yellow and blinking, and the Read command in Status tab of the Log Configuration doesn't show anything. Same happens on some of the Operator Stations.
Engineering station has the same problem, but at least you can see the OPC status of the data in Log Configuration...
I tried restarting the QCS server and it didn't work.
I also tried restarting Basic History service for QCS and it didn't work.
In the attachment you can find configuration snapshots.
Thanks in advance!
You have stated that the History 1.2-1 is installed on all nodes. Please verify in the Admin Structure on each node that the "ABB 800xA History Connectivity" Extension is both Installed and Successfully Loaded on each node, similar to below. The version below is older, however the presentation should be the same.
