Using Labview for an Automated Test Equipment

[anoopson]

Hello All

I am new to Labview and a beginner has not worked a lot with FPGA modules.

I need to setup a Automated Test using Labview FPGA.

I am using a Climate chamber with a Ethernet Connection.

Any help, all informations are most welcome.

Many Thanks in Advance

Best Regards

Can you share more about the application and hardware you plan to use? 

Loop times? Processing requirements? Will you use PXI or cRIO for the LabVIEW FPGA platform?

Hi Terry

Thanks for your reply

I will send a flowchart of how the System works in general

Will you use PXI or cRIO for the LabVIEW FPGA platform? 

I am planning to use a PXI.

NI 783xR/784xR/785xR Only

Thanks and Best regards

FPGA seems WAY overkill for what I see in that flow diagram.  You can do most of that with a simple DAQ board that is at least 1/2 the price.  If you are using a desktop, get a PCIe card that will do what you want.  If a laptop, USB DAQ should do the job as well.

Hi Crossrulz

I already have an NI PXI-7841R in my Lab, this Module provide both Analog and Digital I/O interface.

So there is no investment needed extra I would like to use this module for the respected application.

Since we need a Frequency Generator, It would be great to program it in Labview and do not use an extra Function generator. With my knowledge I programmed a basic Labview GUI. I would like to share it in the form, so that you will have a clear idea of the system. I would like to build with FPGA.

I agree with crossrulz; I do not see the need for FPGA.

FPGA is needed when you need loop times that are in the microsecond range and/or when there is a lot of processing that must happen.

FPGA will add to cost, time, and risk of the project.  It may be better to learn FPGA on a simpler project, that can be an exception.

Thanks Terry & Crossrulz,

For the input you both provided.

What would you suggest to start with.

Best regards
