OPC connection gets disturbed frequently
I am using 800M redundant controllers with Compact HMI V5.0. Very frequently i observe cross marks in the display area. At times when i enter the set point in the faceplate , the cross mark disappears. But most the times i have to close the workplace and re-start the system. This kind of activity is observed 3 to 4 times in a day. OPC files have not been disturbed too. Kindly help on this issue.
Thanks in advance.
