"Display in display"
You can insert further displays in the background (Help display), even as a function of the
values of variables.Like for softkeys you can assign a graphics file to a display field.
Examples:
● Short text field is overlaid with graphics:
DEF VAR1=(S///,"\\image1.bmp" ////160,40,50,50) ;Type S irrelevant
● Toggle field overlaid with graphics, the graphic being selected with a PLC flag byte:
DEF
VAR1=(IDB/*1="\\image1.bmp",2="\\image2.bmp"//,$85000/wr1//"MB[0]"//160,40,50,50)
The height of the displayed graphic (of the I/O field) is specified as the fourth parameter in
respect of the positions. You can also define bitmaps in fields (short text, I/O field).
