Overview

This VI is an example that demonstrates how you can create a event structure based on a value change in a cluster.  The VI then extracts the index of the element in the cluster whose index was changed.  

This example is useful because extracts the index of the element in the cluster that has been changed.

 

Description

Use Event Structure to handle any value change in the cluster elements. The property node Controls[] of Old Values and New Values allows to compare both and determine which element of the cluster has changed.

 

Requirements
