Issue Details

I have two computers which are running different test sequences. These test sequences should communicate with each other in some steps. I am using LabVIEW with my application. How can I make this communication happen?

Solution

There are multiple ways to connect two LabVIEW applications so they can talk to each other. Use these communication techniques to develop your connectivity between sequences:

 

  1. Using Shared Variables
  2. Using SystemLink Cloud's Messages API
  3. Using LabVIEW's VI Server
  4. Performing low level TCP or UDP communication
  5. Using a Web Service

 

You can find more options to connect between a Host PC and a Distributed application in the following white paper: Understanding Communication Options Between the Windows HMI, RT Processor, and FPGA (refer to the section 6. "RT/HMI Communication") 

Additional Information

National Instruments recommends not depending on more than machine running a test sequence to ensure maximum reliability.

 

If you require connecting to a server's database to log results, please consider using the built-in TestStand reporting options instead.
