Access & modify DAQmx resources on RT target from host LabVIEW app.

[Phillip_Neir]

Is there a method to access, create, or edit DAQmx tasks, scales, device configuration, etc. on an RT target from a host LabVIEW application. For example, as part of application initialization, I would like to read the device configuration of a PXI chassis. I would like to select from a list of scales, create/edit/delete a scale on the target. Is there mechanism in LabVIEW to do this, or will I have to develop something to provide this functionality using shared variables?

LV 8.0.1, RT 8.0.1, NI-DAQ 8.1.0f1, PXI-1010, PXI-8184

Phillip Hello.

I am not aware of an inherent LabVIEW feature that will allow you access properties of your Real-Time system from your host. Like you suggested in your post, you can get the data you require from the target and transfer it back to the host via shared variables. This sounds like the easiest option.

Greetings Efosa,

Thank you for your reply. I was able to implement a scheme to upload and download DAQmx info. I have to maintain a working copy of DAQmx info on the host machine and download a copy to the target. It seems to work well enough, but I'm not sure of how easy it will be to manage over time. For those of us that have dynamic configurations, where tasks, channels and scales change with each test session, it would be helpful to have a direct connection to the target resources.

Phillip Hi.

I agree with you. I definitely suggest you filling out a product suggestion here. We take product suggestions very seriously, especially those from customers.
