MiningEquipmentIdentification represents numerous identification features of a mining equipment. It is a subtype of the 4:MachineIdentificationType.

MethodSet is representing a collection of Methods that can be triggered by this Object.

Monitoring represents a collection of ObjectTypes and VariableTypes, representing the current state of the process, that are not assigned to a component but to this Object.

MachineryBuildingBlocks is representing a folder that directly references all those building blocks of the OPC UA for Machinery (OPC 40001-1, OPC 40001-3) which are implemented as an add-in.

The components of the DriveControllerType have additional references which are defined in Table 17.

7.2.2 ConveyorStart

The Method ConveyorStart enables the conveyor to be started. The signature of this Method is specified below. Table 19 and Table 20 specify the Arguments and AddressSpace representation, respectively.

Signature

	ConveyorStart (
		[in]	0:Double	SavedTorque,
		[in]	0:EUInformation	EUSavedTorque,
		[in]	0:Double	TargetSpeed,
		[in]	0:EUInformation	EUTargetSpeed,
		[out]	0:Boolean	TargetSpeedReached
	);

Table 19 - ConveyorStart Method Arguments

Argument	Description
SavedTorque	The last measured torque of the motor that is stored in system.
EUSavedTorque	Represents the Engineering Unit of the SavedTorque Variable.
TargetSpeed	The speed that the conveyor should reach.
EUTargetSpeed	Represents the Engineering Unit of the TargetSpeed Variable.
TargetSpeedReached	Indicates that the target speed has been reached. This Variable is returned when the "True" status has been reached.
