A communications system for an automated irrigation system includes one or more communication lines connecting one or more irrigation units and a main control system of the automated irrigation system, a communications device and a means for transmitting and receiving digital data across the communication lines. The communications device generates the digital data in the form of pulsed signals that are transmitted and received by irrigation fluid flowing through irrigation lines of the irrigation system. The digital data generated and transmitted can be used, for example, to create a data network between the irrigation units and the main control system, to program or reprogram the irrigation units and to provide power to the irrigation units.
