The released document specifies the CANopen interface for operator environments with human-machine interface (HMI) functionality. Operator environments include simple remote control units, operator seats with integrated joysticks, foot pedals, pushbuttons, indicators, etc., and complete operator cabins. Such equipment is dedicated but not limited for construction, mining, agriculture and forestry machines, for harbor cranes, for boats and vessels, for wheelchairs and any other kind of machines on wheels.
The document recommends also the numbering of the operator environment devices depending on the location (for left and right hands or feet). In addition, the numbering of components in a device is suggested.
“This recommended practice is very helpful for the system designer,” explained Holger Zeltwanger, CiA managing director. “It reduces significantly the commissioning and configuration, because pre-programmed routines can be re-used.”
