Attribute 'nameprefix'dl-permalink__symbolPermalink

The attribute defines a prefix for variables of a structured data type. The prefix must be prepended to the identifier of variables that are declared by this type.

Insert location: In the line before the declaration of a structured data type

Syntax: 

{attribute 'nameprefix' := '<prefix>'}

Example

In the following example, Static Analysis issues a message for pB because the variable name does not begin with "point".

{attribute 'nameprefix' := 'point'} 
TYPE DATAPOINT :
STRUCT
	iX: INT;
	iY: INT;
END_STRUCT
END_TYPE

PROGRAM PLC_PRG
VAR
	pointA : DATAPOINT;
	pB : DATAPOINT; 
END_VAR
pointA.iX := 1;
pointA.iY := 10;
pB.iX := 2;
pB.iY := 20;

Error message after static analysis: “Invalid variable name 'pB'. Expect prefix 'point'”
