Abstract
A connected lighting fixture network system has a plurality of multi-channel lighting fixtures. Each lighting fixture (device) has a plurality of services that reside within an application layer of the device. A controller is coupled to the device and configured to send query and command message to the device and to receive reply messages from the device. One service available to the device is a lighting command and control service. The device is configured to receive a query message from the controller. The controller is configured to generate a lighting control and command message, which can include a channel illumination field (CIF) and an illumination payload. The CIF indicates the channels of the device to be commanded based on the status of the channels received in the first reply message. The illumination payload indicates the intended illumination level for the corresponding channel.
