Control a panel object, such as a control, indicator, or the panel itself, by creating a control reference to the object. Control references are either strictly typed or general. Use control references with the Panel Manipulation nodes to control panel objects programmatically.
Strictly typed control references include data type information and accept only references of the same data type. For example, if a subVI accepts a strictly typed control reference that contains a 32-bit integer data type, you can wire only a reference that also contains a 32-bit integer data type to the subVI.Complete the following steps to create a strictly typed control reference:
General control references are flexible in the type of data they accept. For example, if a subVI accepts a general slide reference, you can wire a reference to a 32-bit integer slide, single-precision slide, or a cluster of 32-bit integer slides to the slide reference terminal of the subVI.The Behavior section on the Item tab displays the following statement if a control reference is general:
Reference does not include value data type
