I need charcurve, defined with FB "Charcurve" to be manipulated from touch screen. Is there any way to change values of Array of points (defined for FB "Charcurve") by variables that can be defined with fixed addresses?
My goal is to control the relationship between outdoor temperature and coolant temperature and change this relationship through touch screen. Any solution is welcome.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
if you do it by the manual like
list AT %MW100: ARRAY [0..10] OF POINT := (X:=0,Y:=0),(X:=250,Y:=50 etc );
then you can manipulate all positions the way you like.
You can also do it without this point structure as it is rather difficult.
i tried to put it into a bar display but that does not work with structures
You can copy an array to a single array to visualize.
