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" )
RunGlobalProcedureOnTrue
This function directly executes a global procedure when the value of a specified tag/expression becomes
TRUE.
Function Group Execution Windows Embedded Thin Client
RunGlobalProcedureOnTrue
Module Activity Synchronous Supported Supported Supported
Syntax
RunGlobalProcedureOnTrue("strCondition",strProcedureOnTrue)
RunGlobalProcedureOnTrue( "strCondition", strProcedureOnTrue )
strCondition
A project tag or expression.
strProcedureOnTrue
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.
The name of the procedure (i.e., a VBScript function or sub-routine defined in the Procedures
folder) to run when the value of strCondition becomes TRUE (non-zero).
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 tag/expression becomes TRUE, the procedure is executed. However, the procedure is executed only once
when the tag/expression becomes TRUE; it is not continuously executed while the tag/expression is TRUE.
The procedure is executed on the Client. To execute a procedure on the Server, use the
RunGlobalProcedureOnServer function.
