It is assumed that basic concepts and motivations of OPC UA information modelling from OPC 10000-1 are understood in this document. This document will describe the abstract Application Case Discontinuous Unloading and its constituent Use Cases. These have been developed by a Specialist Working Group and serve as a base for the OPC UA information models of machines and systems taking part in the discontinuous unloading process as part of the load-and-haul cycle.

Note that OPC UA terms and terms defined in this specification are italicized in the specification.
