Operator (#) for direct access

It is possible that local components of a function block override library POUs with the same name, which causes ambiguity. As a result, access with the usual namespace convention is not possible. Then it is helpful to use the ‎#‎ operator to force direct access.

You can use the following syntax to force direct access:

Syntax: ‎<namespace> # <library POU path>‎

Example

TYPE Struct1 :
STRUCT
	Standard : Struct2;
END_STRUCT
END_TYPE

TYPE Struct2 :
STRUCT
	Concat : DINT;
END_STRUCT
END_TYPE

{attribute 'qualified_only'}
VAR_GLOBAL
	Standard : Struct2;
END_VAR

PROGRAM PLC_PRG
VAR
    test : _3S_License#Standard#TON;
    str : STRING;
END_VAR

// access to global variable
_3S_License.Standard.CONCAT := 123;

// with hashtag access, the library is explicitly addressed 
str := _3S_License.Standard#CONCAT('test1', '3444');
str := Standard#CONCAT('test1', '3444');
str := _3S_License#Standard#CONCAT('test1', '3444');
str := _3S_License.Standard#CONCAT('test1', '3444');
str := CONCAT('test1', Standard#CONCAT('3444', '444'));
str := CONCAT('test1', _3S_License.Standard#CONCAT('3444', '444'));
str := CONCAT('test1', _3S_License#Standard#CONCAT('3444', '444'));
str := Standard#CONCAT('test1', Standard#CONCAT('3444', '444'));
str := Standard#CONCAT('test1', _3S_License.Standard#CONCAT('3444', '444'));
str := Standard#CONCAT('test1', _3S_License#Standard#CONCAT('3444', '444'));
str := Standard#CONCAT('test1', _3S_License#Standard#CONCAT('asdf', 'fdas'));
