Linking with PLC
In the simplest case, the Color Control can be used to represent a color variable from the PLC. For this purpose, for example, a PLC variable of type TcVnVector4_LREAL
is linked to the ColorSymbol
attribute. In addition, all Vector3
and Vector4
data types as well as INT, DINT, SINT, UINT, USINT
and LREAL
are supported.

Now PLC variable and the control are synchronized with each other:


The fourth element of the PLC array is ignored, because by default only three channels are displayed as RGB in the control. This can be set via the color format.
