Configuring Individual Channels on an SCC System

[diarmaede]

All,

I am working with an older SCC system with the following modules:

2@AI03

3@TC02

2@SG24

1@AI05

The orginal VI for this system used DAQ Assistant to configure each module individually, with different signal input range, scaled units, terminal configuration and custom scaling.  See attached photos.

I am writing new code, but I don't generally use DAQ Assistant.  Is there a way to configure each module individually without use DAQ Assistant?  I have tried to configure the different modules directly, but I get "Resource not available" errors when I try to run the code.

Or should I just bit the bullet and use DAQ Assistant?

Thanks for any help.

As long as you use the same task, you can use multiple DAQmx channel functions. They would just be connected one after the other.

Ah!  So I just daisy-chain multiple "DAQmx Create Virtual Channel" icons together, then start them all at once, yes?

Thanks!

Since they are daisy chained, they will execute one after another but the task with all channels will start when you command it to.

And just fyi, if you convert a DAQ Assistant to a VI, the generated code will show multiple create channel functions. I believe that does it with the function inside a for loop.
