ISOBUS

CAN bus system according to ISO 11783

Note 1 to entry: ISOBUS is a SAE J1939 based CAN communication bus system, usually used in agriculture and forestry between, such as a tractor, as power supply and at least one implement as load. The communication bus system consists at least of one tractor ECU and one implement ECU. One tractor ECU shall fulfil the functions of a master controller. The tractor ECU (TECU) is a gateway between the ISOBUS and tractor internal bus(es) including the attached controls; thus it exchanges communication objects between both buses, but fulfils also further functions. On-board the implement at least one ECU (also known as Job Controller or Task Controller) interconnects the ISOBUS with the implement application specific controls, optionally via implement internal bus(es); thus, it exchanges communication objects between both buses, but fulfils also further functions.

Note 2 to entry: For details, see the ISO 11783 series.

Note 2 to entry: For a sinusoidal quantity a(t)=Âcos(ω t+ϑ0), the root-mean-square value is A_eff=Â/√2.

Note 3 to entry: The root-mean-square value of a quantity may be denoted by adding one of the subscripts eff or rms to the symbol of the quantity.

Note 4 to entry: In electrical technology, the root-mean-square values of electric current i(t) and voltage u(t) are usually denoted I and U, respectively.
