VeriStand Stimulus Profile API: Stimulus Profile Sessions in LabVIEW

[Frisbee]

Overview

When using LabVIEW to run real-time sequences associated with a particular VeriStand project, you must create a stimulus profile session to control the automation process. This example shows how to configure these sessions and how to respond to the events they generate.

Description

The non-legacy VeriStand Stimulus Profile API does not give us the opportunity to run stimulus profiles directly, so we must create a stimulus profile session to work with real-time sequences the VeriStand engine can execute. Once the session is deployed and running, we can programmatically detect different events associated with them: sequence complete, sequence state change, session complete, and session undeploy events (http://zone.ni.com/reference/en-XX/help/372846H-01/veristandmerge/events_pal/).

To demostrate working with stimulus profile sessions, this example uses the Engine Demo that ships with VeriStand. First the system definition file is deployed and then the stimulus profile session is configured. After the session deploys and runs, an event structure waits for the session to finish before undeploying both the session and the system definition.

*Note: Engine Demo Basic.nivsseq (which is used in this VI) has been modified to include two ByValue parameters, Power and TargetRPM.

Steps to Implement or Execute Code

1. Open VeriStand so that the VeriStand Gateway is running.
2. Replace the Engine Demo Basic.nivsseq stored locally with the attached modified version (or download the attached nivsseq and change the filepath constant in the attached VI).
3. Run the attached RunStimulusProfileSession.vi
