Title: Gaps in DMLogger Output
Post by: Jim77 on February 04, 2019, 12:56:30 PM

I am trying to debug a problem in my deployed system. I currently have a Do-More H2 reading and interpreting a couple of sensors as fast a possible and kicking out results to a PC via DMLogger and TCP/IP to a log file. I run DMLogger as a service in Windows so it is always in the background ready to log.

Typically I get an entry in the file every couple ms, but on rare occasions (about once an hour during operation), I get a whole 10 second gap between data points. It appears that the computer is maintaining other data logs (not generated through DMLogger) during this 10s window, so the PC isn't completely frozen. Additionally, I know the PLC is continuing to scan because the counters continue to increment properly and the log picks back up at the current location, not the next missing data point.

Is there a 10s timeout built into DMLogger somewhere that I am hitting or is there something else going on in my PC that is freezing the DMLogger process causing me to miss messages for exactly 10s?

Thanks.

There are no limits in DMLogger that I'm aware of. Windows is a magical place though were lots of nifty things happen.
