    Hi,
    I created a structure like this

    FUNCTION_BLOCK FB_Base
    VAR
    init : INT := 0;
    END_VAR
    init := 1;
    END_FUNCTION_BLOCK ( i've added this line to clarify, of course IDE does not show it)

    FUNCTION_BLOCK FB_BaseEX EXTENDS FB_Base

    END_FUNCTION_BLOCK ( same thing as the analogous line above )

    When a instance of FB_BaseEx is called, the internal variable init remains equal to 0
    as if the base function code was not executed. is it correct? How can i make the code of the base function also be executed by the child functions?
