Local lighting functions

The application functions of the illumination in the room depend very much on the use or type of room.

The following application functions for illumination are available as templates in TwinCAT 3 Building Automation. All application functions relate to one or more luminaires.

• Lighting group
  With the lighting group application function, switchable or dimmable lighting devices can be switched on and off or dimmed. The lighting group can be operated via light switches, room control units or via graphical operation using TwinCAT 3 HMI.
  This lighting function is implemented in the template FB_BA_LightGroupSwitch.
• Automatic light
  The automatic light application function switches the room lighting on automatically when the room is occupied. Natural illumination by daylight is not taken into account. The light is only switched via presence detection. The function is particularly useful for energy-saving lighting in rooms with insufficient daylight, such as corridors or sanitary rooms.
  This lighting function is implemented in the template FB_BA_LightGroupPresence.
• Constant light regulation
  The constant light regulation application function automatically controls the room lighting or parts of it during occupancy so that it does not fall below a set minimum illuminance. This ensures high-contrast work with minimal energy consumption. While the on-delay and off-delay settings can be used to control switching on before the minimum light level is reached or switching off after the minimum light level is reached, a change in the occupancy status results in undelayed switching. Override by a push button or graphical operation via TwinCAT 3 HMI stops the constant light regulation. Instead, the input value of the push button or the TwinCAT 3 HMI is passed on to the luminaires.
  This light function is implemented in the template FB_BA_LightGroupConstant.
