Abstract

A building management system includes a communications bus, an old master controller device; and slave devices. The slave devices are configured to detect that the old master controller device has stopped communicating over the communications bus and to perform an algorithm to determine a new master controller device from the slave devices. The algorithm is based on a device identifier associated with each of the slave devices. The new master controller device is further configured to assume the functions of the master controller device. The functions of the master controller device include transmitting control signals to the slave devices.
