Very New to VeriStand and LabVIEW

[narra]

We have to develop an automated test environment for our project. So for this we are planning to proceed with NI VeriStand and Lab VIEW we are not sure whether we are choosing accurate tools for the development of automated test environment. So need your suggestions.

Here is the Concept:

1) We have a Microcontroller from NI (uC) with all interfaces like CAN, 2 SPI and UART, a sensor board with SPI interface is attached to uC. And this uC board is interfaced with PXI via CAN, SPI, UART for data acquisition. Then this captured data by PXI has to be displayed in Windows PC which is running with VeriStand and Lab VIEW and at the same time these results have to be documented in a .txt file (for example).

Here below are my questions:-

1) To create this automated test environment do we need to do some programming in Lab VIEW. Let us say a (.VI) script file with all the driver exposed API functions like read, write etc.?

2) For creating result file like example (.txt file) in VeriStand what should we do?

3) Is there any examples are can any 1 please give some ideas to frame the concept with these tools?

Hi narra,

Your description sounds like you have a pretty good understanding of the problem you have to solve but you are not sure about the tools to solve it. Your project does have elements that will require some coding especially if you want to include a clear user interface, an ability to load test parameters, and good error handling so that an operator is not left with a stuck screen. 

If you would like to discuss it further please communicate by email to dclark1952@outlook.com. I have a LabVIEW CLD and many years of experience with the equipment and software you are proposing.

Sincerely,

David Clark

Seems like there are several components to your project but for the little I know about it so far, the simple answer is, yes, you will have to create software modules to perform the tests you want. There are some basic questions you should answer though.

Is this test stand intended for production test of many units or just one off for an engineering sample? 

Do you want a user interface and monitoring screens? Or just a simple entry of test conditions and controls for the test underway? Veristand can make user screens with no programming if the measurement channels are already defined.

How much automation should the test have? 

There's more but if you want to make a useful test stand you have to define all these things. 

Best regards,

Dave

Dear Dave,

Thank you for your reply. Here below I am attaching a pdf file with the block diagram of test bench for your reference. Have a look into it then further we can discuss on this topic. If you need any further info please let me know.

narro,

You started an additional thread for this topic and I replied to the newer one. We can continue with that thread if you like.
