SCADA showing cross after Downloading any modified logic

Hi, I am working on 800xA, PM866 redundant controllers, whenever i am doing any change in my logic and download it to my controller, after downloading in my graphics everything getting crossed for 20 sec to 1 min time not fixed. while at the same time my OPC smiley is healthy.

Which SV You are using?
Is there any software or hardware changes done in controller ?

My SV is 800xA 6.0 Rev A and in this network I have 4 such redundant controllers and this problem is coming on all controllers.
And there is no change on software & hardware.
Please suggest something.

If you have serial communication active, one reason for extended download timeout is due to handling of serial buffers before completing the download. Disconnect these (if possible) and try downloading again to see if this is the problem.

Have you monitored your system diagnostics lately?

Check cyclic and total load on your controller.

You alse can check your ControlBuilder logs on your Engineering station (probably found in ..\ABB Industrial IT Data\Engineer IT Data\Control Builder M Professional\LogFiles\Session.txt). Check file for messages regarding download.

If you are running a very large application it could be useful to split it up in several parts...

Good luck!

I had the similar behaviour when I had several controllers connected to OPC Panel but physically disconnected (not connected to Network)
