7.48 VehicleScaleType Definition

7.48.1 Overview

The VehicleScaleType defines the structure of an Object of the VehicleScaleType. Figure 61 shows the hierarchical structure and details of the composition. It is formally defined in Table 124.

An Object of the VehicleScaleType represents 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 unknown, and more than one measurement is 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 123 shows the process of the different use cases:

7.48.3 ObjectType Description

ProductionPreset, which is inherited from ScaleDeviceType shall have instances of VehicleProductType or a subtype in the Products folder.

7.48.4 Method InboundWeighing

The Method triggers an inbound weighing process of a vehicle arriving in an (e.g., filling) area. This is done to determine the present weight of the vehicle. This method may require a vehicle ID to identify the vehicle and to return the measured value. The signature of this Method is specified below. Table 125 and Table 126 specify the Arguments and AddressSpace representation, respectively.

Signature

	InboundWeighing(
		[in]	0:String		VehicleId
	);

7.48.5 Method OutboundWeighing

Triggers an outbound weighing process of a vehicle leaving an (e.g., filling) area. This is done to determine the total weight of the vehicle. This method may require a vehicle ID to identify the vehicle and to return the measured value. The signature of this Method is specified below. Table 127 and Table 128 specify the Arguments and AddressSpace representation, respectively.

Signature

	OutboundWeighing(
		[in]	0:String	VehicleId
	);

7.48.6 Method OnePassWeighing

Triggers an outbound weighing and uses the preset tare to calculate the DeltaWeight (one-pass use case). The signature of this Method is specified below. Table 129 and Table 130 specify the Arguments and AddressSpace representation, respectively.

Signature

	OnePassWeighing(
		[in]	0:String	VehicleId
	);
