I am receiving a few error messages. "Input queue compacted" and/or "Output Queue Overflow", followed by "National Instruments.OPC Fieldpoint. Server Message. Output Write Queue Length has been exceeded. Output data has been discarded". At this time I lose communication with the tag engine and I can no longer interact with the modules. I have increased all queue sizes from 2000 to 4000 and I still recieve the error. My tag file is only 100 tags, so I should have been okay with the default size. Is there anything else that is recommended. This is Labview 6.1 with DSC.
