LoadingMachineType ObjectType definition – OPC UA for Mining - Loading

5.1 LoadingMachineType ObjectType definition

5.1.1 Overview

The LoadingMachineType provides a representation of loading machines within the MiningEquipmentType as shown in Figure 1. Importantly, it is composed of a ParameterSet Object instance declaration to cover all relevant parameters of the equipment. Intended to be used as an AddIn, as defined in OPC 10001-7, this ObjectType can serve as a type definition of an Object instance declaration called LoadingMachine by definition.

5.1.2 ObjectType Definition

The LoadingMachineType is formally defined in Table 2.
