My LabView program stopped working yesterday and I'm finding it impossible to fix it. Hoping someone here can help.
The problem is manifesting as a failed test within a test sequence, where DIO should be triggered to move a pneumatic part of a machine. When a digital output line is triggered, the machine moves, and I do a VISA read from the device under test. The machine is not responding to the digital signal, and nothing moves, so my VISA read comes back empty. However, both the DIO and VISA have already been used in a prior test without issues.
In a previous test, the same DIO VI is used, with a different input as it triggers another line which is needed for that test. This works perfectly fine, and even if I change the input to this VI to the input that isn't working in the sequence, it still behaves as it should and moves the correct part of the machine. Both tests are contained in different VIs, but use the same DIO control VI. My best guess is that since the DIO works in the first VI and not in the second, they are somehow using a different version of the DIO VI, even though if I open it up it seems to be the same.
I believe I created some conflict/new path errors by accessing the files of the project through a network share. Even though I just opened them and didn't edit anything, there appeared to be lots of conflicts today. I've gone through them all, disconnected from the network drive and painstakingly pointed every file back to the correct path. But still the problem remains - I can get halfway through my sequence before the DIO decides to stop working. Always on the same stage of the sequence.
Any advice greatly appreciated, thanks.
