__POUNAME

Available from TC3.1 Build 4026.

The operator is an extension of the IEC 61131-1 standard.

The operator returns the name of the program organization unit (POU) containing the __POUNAME operator at runtime. To do this, the operator must be assigned to a variable of type STRING in the declaration part or in the implementation part.

The result of __POUNAME depends on where it is used:

• Within a program: program name
• Within a function: function name
• Within a function block: name of the function block
• Within a method: name of the method, qualified with the name of the function block
• Inside a Get/Set accessor in a property: name of the property, qualified with the name of the function block, + Get/Set
• Within a GVL: name of the GVL
• Within a structure: name of the structure
• Within a data structure UNION: name of the UNION

Sample:

PROGRAM MAIN
VAR
    sPouNameDecl : STRING := __POUNAME();  //Liefert 'MAIN'
    sPouNameImpl : STRING;
END_VAR

sPouNameImpl:= __POUNAME();               //Liefert 'MAIN'
