PXI 1044_Xantrex DC Power Supply

[Hllslttncdrngl]

Hi,

I have PXI 1044 and Xantrex DC Power Supply (7.5 V -300A), I want to make a connection between PXI and Xantrex. My actual aim is to measure the Voltage of my samples by PXI while I am applying Current to the samples by Xantrex. I am new to make connections between Supply and PXI, also I am new to PXI, if you help me how to do that I will be appreciated.  Thanks..

Hello  Hllslttncdrngl,

I was wondering if you could elaborate a little more. Why are you trying to connect the PXI Chassis and the Xantrex? Do you know what kind of programming your power supply supports or what kind of connection types it has (Such as ethernet, RS-232, USB, GPIB) ?

Do you know what kind of control you are using in the PXI? Are you using a controller or a MXI card?

Thanks for your attention, I am  trying to answer the questions  you asked

1)Why are you trying to connect the PXI Chassis and the Xantrex? 

I am working on a project , in this project we have samples, we want to test our samples by using current ( up to 300 Ampere), and as we are appliying current we want to measure the voltage of the sample by using PXI, because the resistance of the sample must be really lower than any other conductive.To get the current which is up to 300 ampere I need Xantrex power supply( I am talking about DC current).

2)Do you know what kind of programming your power supply supports or what kind of connection types it has (Such as ethernet, RS-232, USB, GPIB) ?

I have used this Power supply before ,  I made the communication between supply and my computer, I used RS232 connection and , Labview has sample codes for connection (visa) ,I used them , but now I want to connect the PXI with Xantrex. I don't know PXI.

3)Do you know what kind of control you are using in the PXI? Are you using a controller or a MXI card?

I really don't know this answer ,can  you guide me about this topic , if you share a link etc. I can learn.

thanks again

Hello  Hllslttncdrngl,

If you have used LabVIEW and the power supply together in the past, using PXI will be a very easy transition. The code you will use to communicate will be very similar (still using DAQmx or ExpressVIs). What you will need is to select a module/controller to connect to your power supply. Do you know module/card you were connecting the power supply to previously?

Also, I have gone ahead and compiled some resources to help you get started using PXI!

thanks, if I success this situation, I will share here.firstly I have to finish reading the documents that you have sent to me.

Best regards

Hi I have completed my duty ,which I have mentioned above, and now I can use my Labview Code to operate the power supply by PXI. Now I want to measure Voltage by using PXI .But PXI has its own code ,which is on another plotform(DMMsoft) ,but I want to see the measurement results by using my own code.Is there any way to integrate DMMsoft to Labview software?

Hello Hllslttncdrngl,

Instead of using DMM softpanel you can just use NI-DMM directly in LabVIEW. It will work very similar to DAQmx. I have attached a few reference materials to help you get started with NI-DMM in LabVIEW.
