Error in Input and Output Queue for DSC Engine.

[Prashant]

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.

I sometimes get these types of messages when I am writing large amounts of data to the Input Queue.

To avoid this problem, I suggest increasing the size of the queues even more and also try creating a logos.ini file (see the first link below) and increasing its MaxQueueSize and decreasing its LogPeriod.

Why Am I Getting the Alarm "The logging buffer is full"? [broken link removed]
