Operator: __POOL

The operator is an extension of the IEC 61131-3 standard.

The operator is used to reference objects which are managed in the global POU pool (in the “POUs” view). The operator directly accesses objects in the “POUs” view.

Example 

PROGRAM PLC_PRG
VAR
        svar_pou : STRING;
END_VAR

svar_pou := __POOL.POU();
