CTA Deployment & Troubleshooting 4

Question 1

In a deployed TestStand environment, you need to update a code module DLL without stopping all running test stations. Which TestStand feature best supports this requirement?

Accepted Answer

Configuring the code module to load and unload per execution using the 'Load Options' setting

Answer

Setting the code module Load Option to load/unload per execution means the DLL is released after each call, allowing the file to be replaced between executions without a full station restart.

Question 2

A test station's result log shows test steps passing, but UUT fails are not being reported to the factory MES system. The TestStand database logger appears healthy. What should you investigate?

Accepted Answer

The post-execution callback or result processing step that routes data to the MES

Answer

MES integration is typically handled in a post-execution callback (e.g., SequenceFilePostResultListeners or a custom process model step), so a failure there would prevent MES reporting while internal logging continues normally.

Question 3

Which approach is recommended for deploying TestStand system configuration changes (Station Options, type palette) to a fleet of test stations consistently?

Accepted Answer

Use a configuration management script or installer that deploys standardized configuration files to each station

Answer

Scripted or installer-based deployment of standardized configuration files ensures consistency across a fleet and creates an auditable, repeatable process.

Question 4

A newly deployed TestStand station fails with 'Unable to find process model sequence file'. What is the most likely fix?

Accepted Answer

Verify and correct the process model path in Station Options or ensure the process model file was included in the deployment

Answer

If the process model sequence file path in Station Options points to a location where the file doesn't exist on the deployed station, TestStand cannot initialize execution.

Question 5

During troubleshooting, you want to inspect the value of a local variable at a specific step in a deployed sequence without access to the development environment. Which TestStand feature can help?

Accepted Answer

Use the TestStand Execution Viewer or a custom operator interface that exposes variable watch panels

Answer

The TestStand Execution Viewer (or a custom UI with variable watch functionality) allows inspection of execution state and variable values without requiring the full Sequence Editor.
