Data types in PLC Designer

Example for the initialization of a structure:
Poly_1:polygonline := ( Start:=3,3, Point1 =5,2,
Point2:=7,3, Point3:=8,5, Point4:=5,7, End := 3,5);
Initializations with variables are not possible. See an example of the initialization of
an array of a structure under 'Arrays'.
Access on structure components:
You can gain access to structure components using the following syntax:
<Structure_Name>.<Componentname>
So for the above mentioned example of the structure 'polygonline' you can access the
component 'start' by
Poly_1.Start
.
11.2.6 References
You can use the user-defined reference data type to create an alternative name for a
variable, constant or function block.
Create your references as objects in the Object Organizer under the register card
Data types. They begin with the keyword TYPE and end with END_TYPE.
Syntax:
TYPE <Identifier>: <Assignment term>;
END_TYPE
Example:
TYPE message:STRING[50];
END_TYPE;
