Details for DDEntity "400 - Speed Source"

400 - Speed Source Request changes

Definition	The Speed Source that the device uses to report actual speed and to process the setpoint, minimum and maximum speeds. The Speed Source value is an enumeration with the following definitions: 0 = Unknown 1 = Wheel-based speed 2 = Ground-based speed 3 = Navigation-based speed 4 = Blended speed 5 = Simulated speed 6 = Machine Selected speed 7 = Machine measured speed (This option indicates the machine uses an own sensor to measures the actual speed, instead of the speed provided on the bus). 8 to 254 = Reserved 255 = No Source available
Comment	The Speed Source DDI can be used in conjunction with the Actual Speed DDI to specify which speed measurement method is used to determine the value reported via the Actual, Setpoint, Minimum and Maximum Speed DDIs. When a device receives commands for Setpoint, Minimum or Maximum Speed then the Speed Source can be used to select a ISO 11783-7 command for speed control.
