A communication system is provided that includes a controller system (1), a master control (2) and at least one slave control (3). The controller system and the master control (2) are connected via a multipole connection (4). The master control (2) is adapted to receive a multipole signal via the multipole connection (4) and output an addressed signal to at least one slave control (3) via an addressable connection (7, 17). This application also discloses a method of controlling a plurality of fluid flow controls using an output (40) comprising an actuation signal arrangement (41, 41') and an actuator (42, 42') associated with each fluid flow control.
