RDS is the only company in the UK specialising in developing electronics for the agricultural machinery industry. The agricultural machinery industry is undergoing a technological revolution. This being driven in part by an international standard ISO 11783, commonly known as ISOBUS. The principle behind ISOBUs is to enable any suitably equipped implement to be attached to any suitably equipped tractor, enabling the electronics on the implement to be automatically recognised by the terminal on the tractor. As may be imagined - it's not as simple as it may sound. The standard is still evolving and currently extends to 14 sections and over 900 pages. RDS has already invested considerable resources in developing ISOBUS compatible hardware and software solutions. It now needs to extend it's activities to other parts of this complex standard, notably: Part 10: Task Controller. This part of ISO 11783 describes the task-controller applications layer, which defines the requirements and services needed for communicating between the task controller and electronic control units. The data format to communicate with the farm management computer, the calculations required for control and the message format sent to the control function are defined in this part of ISO 11783. Part 13: ISO 11783 as a whole specifies a serial data network for control and communications on forestry or agricultural tractors and mounted, semi-mounted, towed or self-propelled implements. Its purpose is to standardize the method and format of transfer of data between sensors, actuators, control elements and information storage and display units, whether mounted on, or part of, the tractor or implement. This part of ISO 11783 describes the file server for use by a tractor or self-propelled implement.
