I am using version 2.99w. I am using the CLX comms driver. When I start the HMI app I have comms. If I keep activity on the screens by mouse clicks everything works ok. If I walk away for 10 -15 minutes and come back the comms do not work anymore.

Is your PC going to sleep, hibernating, or shutting off the HDD?
-
No I have all that turned off. Even writes to the PLC do not work.
-
Running a Wireshark capture maybe the only way to see what is happening.
-
Anything in particular that I need to look out for? Not familiar with wireshark. I'm new to C# and AHMI. Have only used traditional COTS HMI software.
-
Start the Wireshark capture, then start AdvancedHMI. In the filter, you can put the address of your PLC as such ip.addr==192.168.0.1
After it stops responding, stop the capture and save the file, then post it here.

I have not seen this issue happen again. I had RSLogix open and online at the time. Maybe that caused it. Good thing is the final HMI will not have anything Rockwell on it.
-
I haven't experienced it personally, but I have had reports of RSLogix stopping the AdvancedHMI communications.
