How to execute the same Python scripts in parallel in TestStand?

Question

I am using TestStand with a setup consists of 2 sockets (DUTs). Each DUT is connected with a serial interface to send/receive datae. Now I have a pyhton script which opens the serial interface and exchange data. The python script uses the Com-Port number as input parameter.

So far the python script works for DUT 1 or DUT2 without any problem. Now I would like to implement and use this python sript in TestStand.

Questions:

• is it possible to use TestStand to execute this python script in parallel?
• if yes, how do I need to setup the TestStand in order to run the test in parallel?

When using the batch model I do have access to both DUTs but the data are not coming in parallel and rather in sequence (first DUT1 then DUT2). So I assume there is something wrong in the setup of TS.

Thanks

Answer 1

Yes it is possible to do this in parallel in TestStand.

You would want to use the asynchronous function. Here is an example.
