LabVIEW
Labview does not respond.,the problem has been basically located.
HI,all
Recently, one of my programs has been failing to respond frequently and I have to restart the software.At first, the software architecture was suspected, but after investigation, it was basically determined to be caused by hardware.
The situation is that one DC source and one AC source are connected to the PC via GPIB.There is no problem when running either one alone, but when running both at the same time, there will be no response immediately. I have tried to use USB for AC communication, while DC still uses GPIB. After a brief observation, it seems that the problem has been solved.
I use Labview2017 and I don't know if anyone has similar problems. Next I will try GPIB running two same DCS simultaneously. I hope you can advise me if you have experience.
Finally, I attach the program block diagram of my experiment, which is very simple and two independent programs
I suspect the GPIB bus is running into conflict. I would try combining the two loops so that you get the measurements from one device and then move on to the next instrument.
