7.1 BeltConveyorType ObjectType Definition

7.1.1 Overview

The BeltConveyorType describes the entry point into the information model of a belt conveyor. It is defined in Table 1.

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

Components represents a collection of all identifiable components contained below 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 BeltConveyorType have additional references which are defined in Table 2.

The components of the BeltConveyorType have additional subcomponents which are defined in Table 3.

DriveController is responsible for managing the operation of drive components, such as motors, brakes and fluid couplings, to start, stop, and regulate the speed and tension of the conveyor.

ConveyorDrive is a representation of the drive of the conveyor belt and all its associated data.

ConveyorBrake is a representation of the brake of the conveyor belt and all its associated data.

Belt is a representation of the whole belt in the conveyor involving all sections and splices.

Pulley is a rotating component that drives or redirects the belt, typically at the head or tail of the conveyor.

BeltScale is a weighing system used for the continuous measurement and recording of the mass flow of bulk materials on a conveyor belt. 

WeatherStation is a sensor system that monitors environmental conditions such as temperature, wind, and precipitation near the conveyor.

Scraper is a cleaning device that removes bulk material from conveyor belts and prevents buildup on the belt.

Idler is a representation of in idler, which has at least one ConveyorRoll that supports and guides the belt.

BeltConveyorStateMachine is used to define the different states of the conveyor system which can occur during operation.

7.1.2 Extension of MachineryItemState for belt conveyor machines

For this specification the MachineryItemState defined in OPC 40001-1 UA for Machinery is extended by a SubStateMachine for the State OutOfService, NotExecuting and Executing. An exemplary illustration can be found in Figure 7.

For this, the BeltConveyorMachineryItemState_StateMachineType is defined in Table 4.

The InstanceDeclaration of the BeltConveyorMachineryItemState_StateMachineType has additional Attributes defined in Table 5.

The States OutOfService, NotExecuting and Executing are overriden in the BeltConveyorMachineryItemState_StateMachineType to get the additional reference defined in Table 6.

7.1.3 BeltConveyorOutOfServiceSubState_StateMachineType ObjectType Definition

The BeltConveyorOutOfServiceSubState_StateMachineType is used for a SubStateMachine which divides the OutOfServices State into Booting and NoClearance. This SubStateMachine is not active if the parent State OutOfService is not active. In this case the CurrentState and LastTransition Variables of the BeltConveyorOutOfServiceSubState state machine shall have a status equal to Bad_StateNotActive.

The BeltConveyorOutOfServiceSubState_StateMachineType is formally defined in Table 7.

The InstanceDeclaration of the BeltConveyorOutOfServiceSubState_StateMachineType has additional Attributes defined in Table 8.

The components of the BeltConveyorOutOfServiceSubState_StateMachineType have additional references which are defined in Table 9.

7.1.4 BeltConveyorNotExecutingSubState_StateMachineType ObjectType Definition

The BeltConveyorNotExecutingSubState_StateMachineType is used for a SubStateMachine which divides the NotExecuting State into BrakeClosed, IsStopped, Ready and AlertSignal. This SubStateMachine is not active if the parent State NotExecuting is not active. In this case the CurrentState and LastTransition Variables of the BeltConveyorNotExecutingSubState state machine shall have a status equal to Bad_StateNotActive.

The BeltConveyorNotExecutingSubState_StateMachineType is formally defined in Table 23.

The InstanceDeclaration of the BeltConveyorNotExecutingSubState_StateMachineType has additional Attributes defined in Table 24.

The components of the BeltConveyorNotExecutingSubState_StateMachineType have additional references which are defined inTable 9 Table 25.

7.1.5 BeltConveyorExecutingSubState_StateMachineType ObjectType Definition

The BeltConveyorExecutingSubState_StateMachineType is used for a SubStateMachine which divides the Executing State into ReverseRunning, ForwardRunning and InitialStopping. This SubStateMachine is not active if the parent State Executing is not active. In this case the CurrentState and LastTransition Variables of the BeltConveyorExecutingSubState state machine shall have a status equal to Bad_StateNotActive.

The BeltConveyorExecutingSubState_StateMachineType is formally defined in Table 26.

The InstanceDeclaration of the BeltConveyorExecutingSubState_StateMachineType has additional Attributes defined in Table 27.

The components of the BeltConveyorExecutingSubState_StateMachineType have additional references which are defined in Table 9 28.
