| MSS STSysMaterialTransportLineType Description |
Monitoring represents a collection of ObjectTypes and VariableTypes, representing the current state of the process that are assigned to the component.
MachineryBuildingBlocks represents 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.
Description represents a collection of ObjectTypes and VariableTypes that describe the material transport line. This may be information that is not an identifier for the system and that is static in character but must be stored on the server for some use cases. One example is the mesh size of a sieve, which does not vary but can be queried by cooperating systems.
The components of the STSysMaterialTransportLineType have additional references which are defined in Table 16.

RemainingDurationOfUse represents the predicted remaining time that the material transport line will be in use/occupied in the current process.
FillState represents the occupancy of the material transport line. For the FillState an entry of Table 18 shall be used if appropriate. Since the Variable's TypeDefinition is a MultiStateValueDiscreteType, additional entries can be added if none of the suggested entries are suitable.
AverageFlowVelocity represents the calculated flow velocity of the material in the material transport line.
LifetimeCounters is used as defined in OPC 40001-1. In the information model for material supply systems, all counters shall be implemented according to the MachineryLifetimeCounterType of the OPC 40001-1 and shall be integrated with the HasComponent reference under this Object. This Object shall also be referenced as AddIn in the MachineryBuildingBlocks Folder.
ContactMaterial represents the type of material of the transport line which is in contact with the material transported in the material transport line.
FlowResistanceCoefficient represents the flow resistance between the ContactMaterial and the material transported in the material transport line.
PressureLossCoefficient represents the pressure loss coefficient in the material transport line.
CompressiveStrength represents the compressive strength/pressure resistance of the material transport line.
Length represents the transport length of the material transport line.
CrossSection represents the cross sectional flow area of the material transport line.
The component Variables of the STSysMaterialTransportLineType have additional Attributes defined in Table 18.
