Industrial Automation - Basics - 5.2.8 ControlChannelType

The ControlChannelTypeis 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 7, a graphical overview is given. It is formally defined in Table 26.

SignalOnindicates if the colour is switched on.

ChannelColorshows the channel’s colour.

SignalModeindicates in what mode (continuously on, blinking, flashing) the channel operates when switched on.

Intensityshows the channel’s intensity, thus its brightness. The mandatory EURange Propertyof the Variableindicates 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 InstanceDeclarationsof the ControlChannelTypehave theAttribute values defined in Table 27.

Table 27– ControlChannelType Attribute values for child Nodes

Source Path	Value	Description
SignalOn	-	Indicates if the colour is switched on.
ChannelColor	-	Indicates in what mode (continuously on, blinking, flashing) the channel operates when switched on.
SignalMode	-	Contains a list of audio signals used by this acoustic stacklight element.
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.
