I am using DIO-6361. In MAX I can select the direction of the Digital lines from Input to Output and vise versa. How do I do that using LabVIEW?
For example I need to pull Port1/Line0 to low and then release that Line0. In MAX I can release the Line by selecting "All Input".
I use Digital output to pull Port1/Line 0 to Low
Would just reading the Line0 in LabVIEW release the line?
Go to Solution.
If "release the line" means driving the line back high, you can call another DAQmx write and write a True.
The direction of the line is set by the Task Type you associate the line with, like the create channel function you selected to be a Digital Output.
You cannot change the direction without changing the task type. Whenever you need to change the direction, clear the existing task and create a new task for the new direction.
The NI MAX test panels do the same behind the screen.
