Initially, you should set the HW inputs and outputs in the VI from Connector Pane: Create and Configure a LabVIEW SubVI. Then, you need to create a step and config your I/O (VI) in the TestStand. For this, please follow the following steps:
- Put the action step into the sequence.
- Add vi path (it means that you need to add LabVIEW code which will control your module).
- In Step Settings, you will see inputs and outputs of your vi. So, you can perform config.
Also, if you're going to use any output values for the next steps, so you should save them in variables.
