OPC Communication was disconnecting whenever i have downloading the controller.
Hi everyone,
I am facing the issue in one of my site,
We have installed 800xA in Engineering station and Compact HMI in Operator Station.
Controller used: PM865 - 6 No's in a redundancy fashion.SM811 for the individual controller.
Currently, the System is running in a healthy condition. All the programs are written in 800xA, whenever changing the program and downloading the program in the controller, I am facing the OPC communication failure(OPC Project file path mismatch). So it affects the plant operation.
Every time I need to check the OPC project file path and restart the Operator station , then only the OPC communication getting healthy. Meantime in Engineering Station OPC was healthy, there is no disturbance.
Due to operator station OPC issue, I couldn't able to give the command from Engineering station also.
I want to know the reason for OPC error and root cause for this issue.
Attachments for the better understanding of this issue.

This looks like a version error in the OPC server during download.
For the Freelance OPC Server (here an example) there is a description in the handbooks.
Check the manuals for your system to see if there's a topic about it.
