Abstract: A universal modular control system for controlling a mobile material distribution apparatus is disclosed. The universal modular control system is adaptable for use with any of a plurality of distribution apparatus. It includes a control module for controlling the distribution apparatus and a user console for communicating with a user. The control module and user console are coupled via a data link.

Abstract: A control system for monitoring and controlling the operation of a mobile material distribution apparatus including at least one boom having a plurality of distribution nozzles or distribution ports located along its length for distributing material is disclosed. The control system monitors various sections of the booms and provides the user with a graphical representation of the operating states of the nozzles/distribution ports in each monitored boom section. By taking into account the actual operating states of each of the sections of the monitored booms, the disclosed control system provides more accurate mapping of the materials distributed by the controlled apparatus. In addition, the disclosed control system considers the operating states of any fence row nozzles disposed on the monitored booms in determining the amount of material to be supplied to the monitored booms to achieve a desired distribution rate.
