The CatchweigherProductType defines the structure of an Object of the CatchweigherProductType. Figure 24shows the hierarchical structure and details of the composition. It is formally defined in Table 40.
An Object of the CatchweigherProductType represents a product of a catchweigher. It defines additional methods and properties required for managing the product.

<Zones> is an OptionalPlaceholder for the different zones. Each zone defines different weighing ranges a product has to be within.
LastItem contains the measured values of the last item that was processed by the catchweigher.
PresetHeightdefines the predefined height (in direction of global gravity, see Figure 25) of the measured item. If the PresetHeight value is used, the value must be written before the item is measured.
PresetLengthdefines the predefined length (in direction of travel, see Figure 25) of the measured item. If the PresetLength value is used, the value must be written before the item is measured.
PresetWidthdefines the predefined width (in third possible orthogonal direction to height and length, see Figure 25) of the measured item. If the PresetWidth value is used, the value must be written before the item is measured.

TargetThroughputis the target value for the throughput.
Adds a zone to the zone array. The signature of this Methodis specified below. Table 41and Table 42specify the Argumentsand AddressSpacerepresentation, respectively.

|
UpperLimit |
Upper weight limit of this zone |
|
EngineeringUnits |
Unit of the Lower and the UpperLimit. The two Limits must have the same unit |
|
