High CPU usage ?

[Archie]

Yes Archie it is only 1 element in e.Values, when DataRecived event fires.

This has been confirmed as a bug in the driver. A patch has been made to fix this issue. You can download the  V399v Patch 1 from here:

Thanks Archie, I suppose I will just replace MfgControl.AdvancedHMI.Drivers.dll in my project with this from the patch ?

Unfortunately I won't be able to test it before Wednesday next week, so I will get back with results next week.

Cheers.

Yes, you replace the file found in AdvancedHMIDrivers\support

Thanks Archie it is working, my CPU usage is now around 7-12%, is that too high by your opinion ?

It really depends on your system. But from my experience it is very high. I have run applications with dozens of items on a page with a PollRateOverride of 0 (giving a 6ms refresh) and the CPU still never exceeded 5% on moderate systems.

You may want to do a Wireshark capture to see what is really happening on the communications which may reveal issues in your code.

Ok Archie thanks for advice I will try wireshark as well sometimes during next week and I will post results.

Thanks so much for your support.
