How to communicate with a 9401 module using 9151 expansion and 7813r PXI card

[ACE_Lab]

Hi,

I have just started working with my 7813 R-series card.  I was able to create a simple VI in which I could send and receive digital signals.  Now I would like to do something similar using my 9151 expansion chassis and 9401 C-series module.  If possible I would like to do all of this using windows (no RT for now).  Right now I am right-clicking on "my computer" in the project tree and adding new devices to find the 7813.  From there I have a rough idea of how to build a simple VI using the NI example.  However, I do not know where to look for the expansion chassis or the C-series module.  If any one could give me some advice or point to an example, that would be great.  I have seen the examples in Example Finder for the 9401, but they seem to be using a compactDAQ system as opposed to the PXI setup. 

Thanks for the help!

Hello ACE_Lab,

The steps you should take in order to configure your setup in the LabVIEW project window is as follows:

Step 1...

Step 2...This step should auto-populate with the existing PXI-7813R if it is connected. If you want to setup the target without the card connected, the you can just add a new target as follows.

Step 3...This is the point at which you will be adding the NI-9151 expansion chassis:

Step 4...

Step 5...

Step 6...If you have the module connected to the chassis, you should be able to see the module in the list:

Step 7...If the module is not connected, you can just select "New Target or Device" from the menu in step 6 and add a new target as follows:

An example from the Example Finder called "Digital Line Input.vi" should be a good place to start. Below is a screenshot of roughly where you need to start:
