Title: Send que full, may have lost connection or data request too fast
Post by: amotomura on April 14, 2014, 12:06:17 PM

I have a project that is displaying around 40 Dints on the Main Form using 40 AdvancedHMI.BasicLabels.

I've used this project on other PLC's, but on this particular one, I get an error : Send que full, may have lost connection or data request too fast

It sometimes works, but more often than not errors.

I found this link for a solution, but I'm not sure where to insert the recommended code:

Thanks,

This problem comes typically from a slow communication rate, a very busy Ethernet network, or one with a lot of errors. If you have a managed switch, you can check the error rate to see if there is possibly a bad cable.

You can also reduce the poll rate by changing to PollRateOverride property of the driver. Try setting it to 500 or even 1000.
