Weighing Technology - 7.7 ProductionPresetType Definition

The ProductionPresetType defines the structure of an Object of ProductionPresetType. Figure 19 shows the hierarchical structure and details of the composition. It is formally defined in Table 25.

ProductionPresetType provides methods to manage the Production preset.

7.7.3 ObjectType Description

CurrentProducts is an array containing the Ids of all product objects currently in processing mode. The product process can be started using the SelectProduct method or another interface or an external trigger signal.

Products contains the products used in the scale aggregated in the Products Object . The objects in the folder should have the type ProductType or a subtype of it.

7.7.4 Method AddProduct

The method creates an Object with a subtype of ProductType from the address space. The Object needs a reference of the type "0:HasComponent" to the product folder of the scale device. The signature of this Method is specified below. Table 26 and Table 27 specify the Arguments and AddressSpace representation, respectively.

Note: To simplify the handling, it is recommended that during the creation of the product the object is immediately locked for the client. (see section 8.8)

Signature

AddProduct(

[in]String ProductName

[in]String ProductId

[in]NodeId ProductType

[out]NodeId ProductNodeId

);

Table 26 – AddProduct Method Arguments

Argument	Description
ProductName	A user-readable name of this Batch.
ProductId	A unique Id of this product
ProductType	The NodeId of a subtype of the ProductType or the NodeId of the ProductType itself
ProductNodeId	The NodeId of the created Object

7.7.5 Method SelectProduct

Selects the product. The scale is now able to process the product. This includes that the Id is saved in the currentProduct array and that the ProductMode switches from "Not processing" to "Processing". Table 28 and Table 29 specify the Arguments and AddressSpace representation, respectively.

Signature

SelectProduct (

[in]String ProductId

);

Table 28 – SelectProduct Method Arguments

Argument	Description
ProductId	The ProductId of the product Object that represents the product to be selected

7.7.6 Method DeselectProduct

Deselects the product. The scale should stop to process the product. This includes that the Id is removed in the currentProduct array and that the ProductMode switches from "Processing" to "Not processing". The signature of this Method is specified below. Table 30 and Table 31 specify the Arguments and AddressSpace representation, respectively.

Signature

DeselectProduct (

[in]String ProductId

);

Table 30 – DeselectProduct Method Arguments

Argument	Description
ProductId	The ProductId of the product Object that represents the product to be selected

7.7.7 Method RemoveProduct

The method removes an Object from the address space with a subtype of the ProductType. The signature of this Method is specified below. Table 32 and Table 33 specify the Arguments and AddressSpace representation, respectively.

Signature

RemoveProduct (

[in]String ProductId

);

Table 32 – RemoveProduct Method Arguments

Argument	Description
ProductId	The ProductId of the product Object that represents the product to be selected

7.7.8 Method SwitchProduct

Selects the new product and deselects the old product. The scale is now able to process the new product. This includes that the new Id is saved in the currentProduct array and that the ProductMode switches from "Not processing" to "Processing". Additionally, the old ID is removed in the currentProduct array and the ProductMode of the old product switches from "Processing" to "Not Processing". This method is only possible if only one product is used. The signature of this Method is specified below. Table 34 and Table 35 specify the Arguments and AddressSpace representation, respectively.

Signature

SwitchProduct (

[in]String ProductId

);

Table 34 – SwitchProduct Method Arguments

Argument	Description
ProductId	The Id of the product Object that represents the product to be selected
