So I am using a NI cDAQ-9174 which has AO, AI, DO and DI cards.
I am creating a VI where the user should be able to select the channel(s) to output signals. Signal can be AO or DO
Problem that I am having is that in the Filter Names, I cannot see how to select I/O type as AO and DO.
Basically is the dropdown for 'Output', I want to see all my AO and DO listed.
Is there a way to achive this?
Solved! Go to Solution.
You should be able to right click the control or constant your using to select the AO or DO and choose the I/O Name Filtering option
Let us know if that helps,
Thank for your reply Rebecca.
That is exactly that the problem is.
I can select select the AO or DO but not BOTH.
What I would like to be listed in the dropdown are the AO and the DO. is it possible?
All channels in a task must be of the same I/O type, such as analog input or counter output so you wouldn't be able to have a drop down with DO and AO in the DAQmx Global Channel control.
What you could do is make a DAQmx Task in NI MAX for each of your IO (one for AO and one for DO) then use a DAQmx Task Name Control to select the task you want to use... this has a display all filter.
Let me know if that helps,
