The Controller Area Network (CAN) is an asynchronous serial CSMA/CD+AMP communication protocol for microcontrollers networks, supporting distributed real-time control (bit rate up to 1Mbps) with a very high level of security. CAN communication protocol is based on a distributed scheme, there is no central unit, allowing a direct data transfer between any two or more nodes without a master node mediation. A Building Automation System (BAS) is an example of a distributed control system. In this paper, the CAN bus lighting network is implemented with a reliable two wire control which is required for saving energy consumption or, creating precision lighting effects as a subunit of a BAS. Security systems is also interlocked to a building automation system to monitor the secure premises, control the operation of the overall system, and authorize legal entries as well as to trigger the alarm.
