Figure 8 ControlChannelType overview
The ControlChannelType is used for control channels of single colour elements within a stack element (e.g. RGB elements would use three ControlChannels, one for each controllable colour). In Figure 8, a graphical overview is given. It is formally defined in Table 26.

SignalOn indicates if the colour is switched on.
ChannelColor shows the channel’s colour.
SignalMode indicates in what mode (continuously on, blinking, flashing) the channel operates when switched on.
Intensity shows the channel’s intensity, thus its brightness. The mandatory EURange Property of the Variable indicates the lowest and highest value and thereby allows to calculate the percentage represented by the value. The lowest value is interpreted as 0 percent, the highest is interpreted as 100 percent.
The InstanceDeclarations of the ControlChannelType have the Attribute values defined in Table 27.
