Interfacing
Interfacing is the electrical link between the process computer and the switching/controlling the electrical greenhouse equipment. Components to do so are usually integrated in the switchpanels and hooked up to the outputs of the process computer. On a higher level, when equipment is provided with a so-called BUS-system, interfacing is done by means of a digital signal over only a 2-wire cable. This communication cable runs along motors, pumps or fans and, besides saving you a lot of cable, is also able to manage a great deal of digital information from and towards the process computer.
