This International Standard provides the means to enable communication between on-farm process computers of stationary and mobile agricultural equipment or machinery, and management computers. It therefore specifies an Agricultural Data Interchange Syntax (ADIS), to exchange data electronically. It implies that the syntax is not intended for real-time data exchange. ADIS may be used (see figure1) for direct data exchange between process computer and management program. ADIS may also be used for data exchange between process computer and interface software of the process computer on the PC. Alternatively for this exchange, manufacturer-specific methods can be and are used for data exchange between the interface software for the process computer on the PC and the management program. NOTE2 This does not mean that ADIS cannot be used for other data interchange. Many farmers use a method similar to ADIS to exchange data between management computers and external computers: ADIS can be used for data interchange to external computers. ADIS can also be used to exchange data between independent software applications used on a management computer. Figure1 ADIS application possibilities NOTE— Interface software is a communication program for the process computer that runs on the management computer. It takes care of the data exchange, and creates and reads the ADIS file(s).
