ISOBUS update--"convergence" of compliance.

ISOBUS--an existing method for allowing worldwide electronic interconnectivity between tractors and implements--is to tractors and implements as USB (short for Universal Serial Bus) was to PCs on your desk top, at least to some degree. USB made things work together. (Remember the dreaded Serial Port Stress Syndrome?)

ISOBUS is an industry and marketing term for implementing the ISO 11783 agricultural standard. ISOBUS is not quite as far along or as slick as USB, but it is similar with its particular goal of getting worldwide agricultural electronics to work together.

Two Controller Area Network (CAN) standards (J1939/ISO11783) were initiated by manufacturers in 1990/91 as a common way to handle electronic control over a serial network. Much significant production and implementation has taken place over the last few years.

Picture this: In a network on a vehicle, little electronic boxes "talk together"--like people on the same telephone party line. The term "party line" is significant. Are they talking the same language, and are they following any rules?

ISOBUS Compliance is a test document/process that checks for that common language and rule following. It was formally balloted and released in 2005. It keys off the significant portions of the ISO 11783 standard for this testing. The document is "kept up" by the ISOBUS Design Community of North American ISOBUS Implementation Task Force (NAIITF) and the European Implementation Group ISOBUS (IGI). At the present time, a laboratory in Germany (DLG) is the hub for validating electronic products.

Of course, every company wants their products to work well. To support this goal, numerous areas of the controller/display are complete and being tested: physical and communication layers, Virtual Terminal (VT), tractor electronic control unit (TECU), etc. A new and significant point is that the "File Server" test section has successfully passed ballot and will be incorporated in the test. Upcoming sections planned are: task controller (map and global positioning system-based controls), diagnostics, and the long-awaited VT Version 3.

Vehicles and implements can work together with the same-parameters, methods, and diagnostics. This work will continue to grow, and compliance testing will keep the methods common and verifiable. This, of course, only works for those who participate in the standard.

Does your research and/or products follow this method? What about the other farm-related electronics, wireless sensors, and networks? Should these be integrated together? Or will they be talking on a party line in disparate languages?
