Issue Details

I'm using a cDAQ with a C Series Current Input Module. Is it possible to access the physical channel settings from the front panel at run time using a Property Node for Analog Input channel to change the settings in DAQmx Create Channel vi? 
For example: Change AI0 from voltage to current to thermocouple reading together with corresponding settings.

Solution

No. Property nodes will not be able to be used to edit the Physical Channel Settings. With the physical channel information alone you cannot set specific physical channel settings. This is because DAQmx can see all of the possible phenomenon it may measure and cannot deduce exactly which one to be used. 

The below screenshot shows a small VI obtaining the Active Physical Channels possible measurement types and showing that it returns several hence it is not possible to deduce a change on the physical channel alone.
