Wonderware Historian Client has BAD values in Trend

I am using Wonderware Intouch 2012R2 with ControlLogix and accessing PLC data on ethernet using local DA server. The problem is with my local historian. When i see a trend of a tag in the historian client, there are some BAD Quality values which are causing gaps in the Trend. Please see attached image. Help is required to resolve this problem.

That looks like a timeout on your IO server to me. It will talk for a short time then timeout and reconnect after the delay in the configuration settings.

More specifically, a timeout from your IO server to your device.

Thanks for the help. How to resolve this problem? WindowViewer and WindowMaker are not showing any such errors. Trends in Windowviewer are working fine.
