“Array of points”

Variable (‎POINTER TO‎) which points to an array of the structure ‎VisuElems.VisuStructPoint‎

The elements ‎iX‎ and ‎iY‎ of ‎VisuStructPoint‎ contain the X/Y-coordinates of a point The current number of array elements implicitly contains the variable in the property “Number of points”.

The variable that is assigned to the property “Number of points” contains the number of array elements and therefore the number of corner points.

Example:

‎pPoints : POINTER TO ARRAY[0..100] OF VisuElems.VisuStructPoint;‎

“Number of Points”

Variable (integer data type) which contains the number of array elements and therefore the number of corner points for displaying the element

Example:

‎PLC_PRG.iNumberOfPoints := 24;‎

In the example, the element has 24 points. This definition is necessary because the individual points are defined by a pointer and this does not allow control over the number of points.

NOTE:

In this way, it is possible for example to adapt the display of the element dynamically by updating the number of corner points.
