System Status Viewer
Could anyone help me in resolving the below issue.
In system Status Viewer Aspect, it is showing "No Connection to OPC Server".
But OPC server is connected and OPCDA is also working fine.
How to configure to get the system status aspect up and running.
800xA System version 5.0 SP2 Rev C
Thanks in advance

I suspect something is wrong with the Function Diagrams you are using.
The System Status viewer is a "dumb" application which *only* iterates all children and ask "Do you have a S_STATUS property and maybe also a S_DESCRIPTION and S_TIME property for me?"
S_STATUS = 0 --> Green
S_STATUS = 1 --> Error
S_STATUS = 2 --> Warning
AC800 Connect uses the Property Translation aspect to calculate the S_xxx properties from HwState, etc. which can be read from the AC800 OPC Server.
I believe you have Function Diagrams that exposes one or more of these, but a large portion of them are unable to deliver any OPC data.
I have made a simple example below where I used a PG2 Property List control and Late Binding's LateBoundPropertyRefArray() function to search my Control Project for objects exposing S_STATUS properties.
The image is just for your reference, it does not "solve" the problem - but may assist understanding where S_STATUS properties are found, etc.
I suspect you have a number of Function Diagram aspects (e.g. Allocatable Group) that have issues.
Have you run the control project through the Consistency Checker?
If you can't solve this on your own, please consider contacting your regional ABB support organization.
