A two wire communication system capable of transmitting data and transferring power by means of an electrical bi-polar waveform across a two wire conductor from a controller (1) in communication with said two-wire conductor to at least one module (6, 7, 8) in communication with said controller and capable of transmitting data from said at least one module to said controller (1); the system comprising a remote electrical device in communication with said controller (1) characterized in that the system is capable of continuous transmission of usable data across said two wire conductor independent of and during power transmission between said controller (1) and said at least one module (6, 7, 8) without loss of data transmission time and without affecting the transfer of power to said at least one module (6, 7, 8).
