Detects direct address access in the implementation code

Justification: Symbolic programming is always preferable. A variable has a name that can also have a meaning. An address cannot indicate what it is used for.

Importance: High

PLCopen rule: N1 / CP1

PROGRAM PLC_PRG
VAR
	xVar : BOOL;
	byVar : BYTE;
END_VAR

xVar := %IX0.0;
%QX0.0 := xVar;
%MX0.1	:= xVar;
%MB1	:= byVar;

--> Access to direct address '%IX0.0'
--> Access to direct address '%QX0.0'
--> Access to direct address '%MX0.1'
--> Access to direct address '%MB1'
