Select multiple IO type in DACmx channel filter

[sherzaad]

Hi,

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?

Hey sherzaad, 

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 

See Cannot Find Port or Line of My Digital I/O Device in LabVIEW DAQmx Physical Channel Control

Let us know if that helps,

Hi,

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?

Hey Sherzaad, 

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,
