Details for DDEntity "397 - Actual Speed"

397 - Actual Speed Request changes
DefinitionThe actual speed as measured on or used by a device for the execution of task based data, e.g. to convert a setpoint rate expressed per area to device specific control data that is expressed as a rate per time. The actual speed can be measured by the device itself or it can be a speed value that is obtained from one of the speed parameter groups that are broadcasted on the ISO11783 network and defined in ISO11783-7. Examples of broadcasted speed parameter groups are wheel based speed, ground based speed and machine selected speed. The source of the actual speed can be specified by a Speed Source DDI that is present in the same device element as the speed DDI. A positive value will represent forward direction and a negative value will represent reverse direction.
CommentThis DDI has been added to the data dictionary to support logging of the speed that the device uses for processing and for generation of task data. The addition of a DDI for actual speed allows speed values to be added to the default data set that devices present to a task controller or a data logger.
