Hardware: NI PCI-MIO-16E "DEV1" connected to an SCB68.
I have a Global Virtual Channel "KeyRun" assigned to Dev1/port0/line1
Within some VI in the project, there is something writing to that port/line directly without using DAQmx. I renamed the Global Virtual Channel to another name and the rogue VI still wrote to the port/line. I renamed the device and the rogue VI still wrote to the port/ine.
The code was originally created before 1996 and has been passed through multiple people. I'm guessing there is an old way of writing to I/O of which I'm not aware. I'm not even sure what to search for other than DAQmx VI's, DAQmx global channels and property nodes.
