Static digital output on PFI, M-Series, Labview, DAQmx

I have the same question as previously posted but not actually answered, "How Do I Use the PFI Lines of My M Series Board For Static Digital Input or Output?" [I am using an M Series board, and the specification sheet says that the PFI functionality includes static digital input and output. However, when programming within LabVIEW I can't seem to access a PFI line using the physical channel constant.]

I haven't had any trouble with the usual Digital IO. It's quite clear how to route timing signals through PFI, but it's not clear that it is at all possible to use the PFI lines for static digital IO. The reply to the previous post says "it will be listed as P1x/P2x." Where is that list? I can't seem to find any listing that includes anything of that form. (For timing signals there is indeed such a list.) I've tried entering every simple permutation of that form entered into the physical channel constant, but I haven't had any luck. Short of LabVIEW actually containing a list, can anyone tell me an example of a physical channel constant that works? (I have determined, for example, that (Dev1/P11) and (Dev1P1.1) do not work.)

The nomenclature "PX.Y" in the hardware manual or device pinouts help will correspond to a physical channel name of "[deviceName]/portX/lineY" which you should see from the physical channel control drop-down list.

Here's an example: your device is "Dev1" and you want to perform static digital I/O on PFI5. PFI5 corresponds to P1.5 (according to the device pinouts help file that you can get to from MAX). This would correspond to a physical channel name of "Dev1/port1/line5"

Good luck,
Joe
