I cannot create Safe Box Zone. Im doing like in example :

VAR shapedata SafeBox;  
CONST pos P\_Corner1:=[200,100,100];  
CONST pos P\_Corner2:=[600,400,400];

LOCAL PROC Declaration()

WZBoxDef Inside,SafeBox,P\_Corner1,P\_Corner2;  
WZDOSetTemp,WorldZoneInside,SafeBox,dq\_SafeWarning,1;

ENDPROC

The error that i got is " Reference to unknown procedure WzBoxDef. Why rapid see WzBoxDef as a procedure?

World zones is an option that doesn’t come by default. For a virtual controller you need to add it in system builder and for a real controller you need to buy it.
