Verify a DAQmx Task is a particular type of task

[hecmar.arreola]

I'm trying to find a method in LabVIEW to verify that a DAQmx Task contains a particular type of task.  For this particular application, I want to verify that a DAQmx Task is a Digital (Line) Output before executing it.

Regulating the IO Filtering of a DAQmx control is an option for me, but this code will be used by other programers and I would like to add this extra check w/ error handling in the event that the Task to does verify to be of the correct type.

Thank you for your input.

You could use the DAQmx Channel Property Node and read the ChanType property. If it's the Digital Out of a line, Digital Output

Use the Channel Property-> Channel Type property node and it will tell you what type of task it is.

Ah ha!  Thanks you guys!  Didn't occure to me that a DAQmx Task can be fed to a DAQmx Channel property node.
