I have a LabVIEW project with a Real-Time PXI VI and a PC VI running on a private network.
I have shared variables hosted on the PXI RT processer. Both the PXI VI and PC VI read and write to shared variables. The PC has two front panel bindings for each shared variable, and the PXI has one wiring diagram read node for each shared variable.
Everything runs fine, but after about 24 hours, I lose the ability to read the variables. There is no error. When I connect with distributed system manager, the values shows good. If I update one of the PC’s front panel objects that is bound to the shared variable, the other front panel object and the PXI shared variable read node does not see the update, but the distributed system manager sees it. It appears the connections are unable to read, but able to write. No errors are shown on PSP LED.
