Check if external power for module (NI 9207) is on?

[mikep815]

I'm trying to write a VI that checks if everything is connected properly (as much as possible) before running some automated tests.  So far, I detect whether the USB to the cDAQ-9178 chassis is connected and then if all of the modules are connected and in the correct slots. 

Two of the modules that are being used (NI 9207, NI 9265) require that an external power source be connected to the Vsup pin.  Is there and way that i can 'read' these Vsup pins to determine whether or not the operator turned on the external power supply prior to running the automated test?

Hi mikep815,

The NI 9265 can tell you whether a voltage is present on the Vsup pin using the DAQmx Write >> PowerSupplyFaultChansExist property. There is also a PowerSupplyFaultChans property which you can use to determine which NI 9265 has a power supply fault, if you have more than one. However, the NI 9207 does not have a similar feature.
