TwinCAT 3 Colour Variables

Hello. I am working on TwinCAT 3 visualization.


I want to fill the colour of a rectangle in the visualization using Fill colour . The variable I defines is an array of DINT which includes different colour codes. By implementing different condition


I want to know How can I get the light green colour using 16#TTRRGGBB or 16#FF8FE03F ? I mean i can get red colour using this value 16711680, hex value= FF0000. But How to get light green colour? Can someone explain me about how colour variables work in TwinCAT 3. I have also added the explanation below.





Thanks in advance.

Color variables


The color variables used for dynamic definition of the element colors via project variables of type DWORD. A color is defined based on a hexadecimal number consisting of red, green and blue (RGB) components. In addition, the variables are used to specify the transparency of the color (FF: fully opaque - 00: fully transparent). The DWORD has the following structure: 16#TTRRGGBB


Example:

nFillColor := 16#FF8FE03F;

▪FF: transparency (fully opaque)
▪8F: red
▪E0: green
▪3F: blue

The help note pretty much spells it out. What exactly are you having trouble with? If you specify 16#FF8FE03F as the fill color, you should get a light green. Is this not the behavior you are seeing in Twincat?

find a colour wheel, or a global var list.
i do it by using a dialog and then write down the colours needed in the global vars.

What data type should be this variable? I tried dint, udint, string, but non of them works.


I'm using TE2000 TC3 visualization.

The "help" copied by the OP says type is DWORD.
