800xA - No inner connection to current data - probably OPC problem?
Single station system with one redundant PLC. 800xA 5.1 FP4.
In attachment you can see:
- settings for OPC: Service, Service Group, Provider;
- service status (everything is running & ok)
- settings of control network for OPC definition
In Startup Display from Object Exlplorer I put several elements to display value of FB SignalBasicInReal (in Control Builder I can monitor they are working). See attachment.
Going to operator workplace I see all the objects in dead state - they display nothing, not even zeros. See attachment.
It seems like data is not transfered to graphics at all.
By the way Alarm&Event are working all right - I see them & acknoledgment is availiable.
If I connect with Matrokon OPC Explorer - OPC server is availiable, and in the same tags I see living data. See attachment.
What could be wrong in settings?
What components to reinstall?
