How to set a I/O channel in NI PXIe-6556 to ground when in PMU mode

[raffythegreat]

Is there a way or API call in LabVIEW to set any one of the channels to ground within the PXIe-6556 when in PMU mode?

If you disconnect the PMU, you will have the option to go to tristate or your previous digital state, but not ground. Forcing 0V is probably the closest you can get to a GND like behavior. The default line state is tristate for this device, which will leave the line floating if there is no active driver.
