What causes OFS to give a Polling rate overrun message?

Polling Rate Overrun is when OFS is requesting too much data and the PLC is not able to respond in a timely manner. The Minimum Update Rate could be increased to give the PLC more time to respond.

-Locate the file named 'OFSinternal.xml' and make a backup copy of it. It should be in the following path: C:\ProgramData\Schneider Electric\OFS\3.60.0.0\
-Open the file named 'OFSinternal.xml' using 'Wordpad.
-Change the view to 'Word wrap to ruler'.
-Change the value of the "MinUpdateRate" value="1000".
-Save the changes.

NOTE: The path above is for OFS v3.6 but it will also work for v3.5 but the path will be different.
