The FeederModuleType defines the structure of an Object of the FeederModuleType. Figure 13 shows the hierarchical structure and details of the composition. It is formally defined in Table 12.

An Object of the FeederModuleType represents a feeder system. A feeder system is a subdevice of an automatic scale for conveying the product (e.g. a belt or a screw conveyor) to or from the weighingBridge. A feeder must be part of another device (e.g. an Object of the ScaleDeviceType).

The Type defines a general communication interface for a feeder system. It contains only variables and methods.

JobName is the human-readable name of the job to which this product belongs.

PresetTare defines the predefined tare weight. The value must be written before the item is measured.

ProductId defines a unique Id of this product.

The ProductMode displays the current mode of the product. The Product can be in the mode "Processing" or "Not Processing". The mode is independent from the LockingService. Thus, it is possible that a product is in the "Processing mode" and writeable. The combination of these both modes should be used with care as the writeable element may be in an inconsistent state. If the ProductMode is true the Object is in "Processing". Otherwise, it is in the mode "Not Processing".

ProductName defines the name of this product.

Lock is used as container for the LockingServices Methods and Properties. It is defined in OPC 10000-100 (Locking). Additonal to this definition also the server can lock an object of the ProductType. In this case the property LockingClient contains the ProductUri of the server and LockingUser contains a empty String.

NOTE: If an Object is writeable not all variables must be writeable. There can be additional restrictions based on the implementation.

Statistic contains the different statistic values of the product. The statistic can’t be reset manually. All measurements that relate to the product of the job will be used in the statistics.

An Object of the VehicleScaleTyperepresents a vehicle scale. It defines additional methods and properties required for managing the vehicle scale.

The following use cases for a vehicle scale exist:

• Checking the weight of the vehicle (e.g. a traffic check or an overload check) (check vehicle weight)
• The weight of the vehicle is known and only one measurement is needed to determine the gross weight (one pass weighing)
• The weight of the vehicle is unkown and more than one measurement ist needed to determine the gross weight (more pass weighing) (e.g a vehicle arrives at a gravel plant full/empty and leaves it empty/full)

Table 118 shows the process of the different use cases:

Table 118 – Proccess of vehicle weighing

Checkweighing	One pass weighing	More pass weighing
Call the method registerWeight to get the current value	Call the method OnePassWeighing to trigger an outbound weighing and use the preset tare to calculate Delta Weight	Call the method InboundWeighing if the vehicle arrives at the area and call the method OutboundWeighing if the vehicle leaves the area. The results must be saved in the scale. If OutboundWeighing and InboundWeighing are stored in the scale the DeltaWeight (as result) can be calculated

The WeighingModuleType defines the structure of an Object of the WeighingModuleType. Figure 61 shows the hierarchical structure and details of the composition. It is formally defined in Table 130.

An Object of the WeighingModuleType represents a weighing bridge. It defines additional methods and properties required for managing the weighing bridge. The Object should be a subdevice of another device (e.g. a VehicleScaleDeviceType).

The MaterialType defines the structure of an Object of the MaterialType. Figure 62 shows the hierarchical structure and details of the composition. It is formally defined in Table 131.

An Object of the MaterialType represents a material. It defines additional properties required for managing materials (for example as part of a vehicle product or in a recipe).

MaterialId defines a unique identifier for the material.

MaterialName defines a user-readable name of the material.

The FloatingStatisticType defines the structure of an Object of the FloatingStatisticType. Figure 63 shows the hierarchical structure and the details of the composition. It is formally defined in Table 132.

The FloatingStatisticType is a subtype of the StatisiticType and also a container for the different statisticvalues. All variables are optional so that the statistics can be instanced application-specifically. The FloatingStatisticType is not used directly in the information model but should be used for application-specific statistics. Unlike the StatisiticType, the statistic behind the FloatingStatisticType is not time-based, but contains the last NumberOfValues values.

NumberOfValues defines the number of values that are considered for this floating statistic.

The TotalizerType defines the structure of an Object of the TotalizerType. Figure 64 shows the hierarchical structure and details of the composition. It is formally defined in Table 133.

An Object of the TotalizerType contains the sum of the last measurement results (totalizedValue). Additionally, it defines a method to reset the totalizer and the addition of the result starts with zero.

TotalizedValue defines a summed up/totalized volume within a period of time.

Resets the TotalizedValue of this totalizer Object . Only useful if the reset is not related to a period of time (e.g. over 1h).
