(K-Bus is a communication system which was developed to connect remote devices (slave devices) to a central point of access (a master control unit), thus allowing remote control and monitoring functions to be performed using an appropriate communication language. It is not designed to allow direct communication between slave devices, but merely between a master control unit and several slave devices. It was initially developed for use in the electrical supply industry at distribution voltage levels, but can equally be applied to other voltage levels or indeed in other systems which would benefit from such a communication system.)
