Syntax

RunGlobalProcedureOnTrigger("strTagName",strProcedureOnTrigger)

strTagName: The name of a project tag.
Note: The tag name must be enclosed in quotes, as shown in the syntax diagram, or else the project will try to get the value of the named tag.
strProcedureOnTrigger: The name of the procedure (in the Procedures folder) to execute when the value of the specified tag changes.

Returned value

This function returns the following possible values:

Value	Description
`0`	Error
`1`	Success

Notes

Once this function is called, it remains active until the runtime project is stopped. That means every time the value of the tag changes, the procedure is executed.

The procedure is executed on the Client. To execute a procedure on the Server, use the RunGlobalProcedureOnServer function.

Examples

When the value of TagTrigger changes, execute the procedure UsingTrigger:

RunGlobalProcedureOnTrigger( "TagTrigger", "UsingTrigger" )
