DAQ Asst Connection Diagram & Error 50103

[E_A_Klein]

Hello LabVIEW Community,

I am currently trying to integrate two different VIs which both require an AIGND on my SCB-100.

The SCB-100 has two separate AIGNDs (pinouts 1 and 2), but in the two DAQ Asst VIs I am using, the connection diagram for both asks for pinout 2.

I think this is leading to a Error 50103 about reserved resources.

Is there any way to switch one of the DAQ Assts' AIGND to pinout 1?

Thank you all for your help.

Sincerely,

The grounds are common and are totally irrelevant to error -50103. The error is because you are using two different DAQ Assistants. Have you done a search here of that code or explanation? Use a single DAQ Assistant with multiple channels.

Thank you very much, Mr. Knutson.

I didn't do a thorough search. I assumed it had something to do with my two DAQ Assistants, and figured it was that they shared a pinout as the error said something about resources being reserved.

I realize I forgot to ask: if I have several channels on the same task, how can I separate the data to be processed differently in the rest of the VI? (I only see one data output)

First - LabVIEW tutorial.

From the DAQ Assistant, use the Split Signals. The dynamic data that you get from the DAQ Assistant is absolutely evil but if you use NOTHING but Express VIs, you may not have any problems.

Thank you.

Look at your functions palette. Click on the Search button.

My functions palette is almost certainly set up differently than yours but you should have somewhere an Express>Signal Manipulation.
