Abstract
An electrical distribution system for selectively connecting an electrical power source to load devices comprises a plurality of panels. Each panel comprises a plurality of load control devices each for connection in a branch circuit to a load device, and an input/output (I/O) controller operatively connected to each of the load control devices for controlling operation of the load control devices. The I/O controller includes a communication port. A programmed system controller is provided for commanding operation of the I/O controllers and includes a communication port. A bus operatively connects the I/O controller communication ports to the system controller communication port. The programmed system controller implements a communication program using a protocol establishing communications on the bus, the protocol including a layer stack translating between logical messages and physical messages for communication on the bus, wherein each layer generates its own thread and communicates to other layers via objects passed in queues to adjacent layers.
