DIO select direction

[lvrat]

Hello,

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?

Thanks!!

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.
