The CatchweigherProductType defines the structure of an Object of the CatchweigherProductType. Figure 24 shows the hierarchical structure and details of the composition. It is formally defined in Table 45.
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.
PresetHeight defines 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.
PresetLength defines 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.
PresetWidth defines 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.

TargetThroughput is the target value for the throughput.
Adds a zone to the zone array. The signature of this Method is specified below. Table 46 and Table 47 specify the Arguments and AddressSpace representation, respectively.
