Abstract: A lighting control system of networks and devices designed to allow scheduled events to continue to operate in the case of partial or full network operation and failure. The lighting control system can rely on any network controller to act as a schedule master that evaluates a schedule of time-based lighting control events. When failure of the acting schedule master occurs or network communication therewith, the lighting control system changes the scheduling master to a different network controller based on a fail over protocol. The failover protocol includes detecting when an acting schedule master controller stops working by, for example, failing to receive a keep-alive message at a different network controller within a predetermined amount of time. Upon detecting failure of the schedule master controller, a network controller with a different controller identifier takes over as the schedule master in accordance with a controller identifier evaluation or protocol.
