Error Out Cluster
TestStand uses the content of the error out cluster to determine when a run-time error occurs and when to take appropriate action if necessary. When you create a VI, use the standard LabVIEW error out cluster.
The following table lists the elements of the error out cluster, specifies the data type of the cluster element, describes how the LabVIEW Adapter uses each cluster element, and specifies the TestStand property to which the adapter copies the cluster element value.
| Cluster Element | Data Type | Description | TestStand Property to Which the Adapter Copies the Value |
|---|---|---|---|
| status |
|
The test VI must set this element to True when an error occurs. | Step.Result.Error.Occurred |
| code |
|
The test VI can set this element to a non-zero value when an error occurs. | Step.Result.Error.Code |

The test VI can set this element to a descriptive string when an error occurs. | Step.Result.Error.Msg |
