The invention relates to a protocol for communications between networked devices. The devices are logically arranged as a hierarchy of device types including a controller device type () from which no other device type depends and a basic device type () from which a number of other device types depend. The devices implement a simple device description message of fixed length and format which includes the device type, and some devices further implement an extended device description message including additional information.
