ProductionDatasetLists – OPC UA for Plastics and Rubber Machinery

20.4 ProductionDatasetLists

The Object ProductionDatasetLists is used to exchange information on the available production datasets on client and server.

The Object ProductionDatasetLists can fire an Event RequestProductionDatasetList to initiate a call of SendProductionDataList by the MES.

20.4.1 GetProductionDatasetList

This Method is used to read a list from the server which production datasets are available on the machine's file system (e.g. for a check before an activation or transfer of a production dataset is initiated). The NameFilter and MouldId can be used to reduce the length of the list or for a targeted search.

Signature

	GetProductionDatasetList ( 
		[in]	0:String	NameFilter
		[in]	0:String	MouldId
		[out]	ProductionDatasetInformationType[]	ProductionDatasetList);

Table 109 – GetProductionDatasetList Method Arguments

Argument	Description
NameFilter	The Filter can be used to reduce the length of the list or for a targeted search. The wildcards "" and "?" may be used. NameFilter* = "" requests a lists of all available production datasets, NameFilter = "300" requests only information on the production dataset with ProductionDatasetName "300" (if available), NameFilter = "3" requests information on production datasets with a ProductionDatasetName* starting with "3" (e.g. "300", "301", …).
MouldId	If MouldId<>"" only production datasets for the given MouldId are requested.
ProductionDatasetList	Array of ProductionDatasetInformationType (see 20.4.4) describing the available production datasets on the server.

20.4.2 SendProductionDatasetList

This Method is used to send a list of production datasets available on the client to the server.

Signature

	SendProductionDatasetList ( 
		[in]	ProductionDatasetInformationType[]	ProductionDatasetList);

Table 111 – SendProductionDatasetList Method Arguments

Argument	Description
ProductionDatasetList	Array of ProductionDatasetInformationType describing the available production datasets in the MES.

Attribute	Value
BrowseName	SendProductionDatasetList

References	Node Class	BrowseName	DataType	TypeDefinition	Modelling Rule
0:HasProperty	Variable	InputArguments	Argument[]	0:PropertyType	Mandatory

It is possible to call the Method without an InputArgument (length of the array ProductionDatasetList is zero) as an answer to the Event RequestProductionDatasetList (see below) if no production dataset which fits the NameFilter and/or MouldId transferred with the event is available.

20.4.3 RequestProductionDatasetList

The Object ProductionDatasetLists can fire an Event RequestProductionDatasetListEventType to initiate a call of SendProductionDatasetList by the client. This can for example be triggered by an operator who wants to load a production dataset not existing on the server.

Table 113 – RequestProductionDatasetListEventType Definition

Attribute	Value
BrowseName	RequestProductionDatasetListEventType
IsAbstract	True

References	Node Class	BrowseName	DataType	TypeDefinition	Other
Subtype of 0:BaseEventType defined in OPC UA Part 5
0:HasProperty	Variable	NameFilter	0:String	0:PropertyType	M
0:HasProperty	Variable	MouldId	0:String	0:PropertyType	M

The MouldFilter and MouldId parameters which can be used to reduce the length of the list or for a targeted search is used in the same way as in the Method GetProductionDatasetList defined in 20.4.1.

20.4.4 ProductionDatasetInformationType

This structure provides information on a production dataset. It does not contain the production dataset file itself.

Table 114 – ProductionDatasetInformationType Definition

Name	Type	Description
ProductionDatasetInformationType	structure	Subtype of 0:Structure as defined in OPC UA 10000-3
Name	0:String	Name of the production dataset (=identifier).
Description	0:String	Additional description of the production dataset.
MESId	0:String	Id of the production dataset file assigned by MES.
CreationTimestamp	0:DateTime	Time when the production dataset was originally created or saved with a new name (in UTC time).
LastModificationTimestamp	0:DateTime	Time of the last modification of the production dataset (in UTC time).
LastSaveTimestamp	0:DateTime	Time when the production dataset was saved to the file system of the machine (in UTC time).
UserName	0:String	Name of the user who has made the last parameter change on the machine.
Components	0:UInt16[]	Informs for which machines information is included in the file. The possible values are defined in Table 115. If the production dataset contains information for two machines of the same types, the enumeration value is repeated. Example: The production dataset contains information for 1 injection moulding machine and 2 robots: Components = [0 1 1].
Manufacturer	0:String	These Properties are representing the values stored in the MachineInformation at the time the production dataset file is created.
SerialNumber	0:String
Model	0:String
ControllerName	0:String
UserMachineName	0:String	These Properties are taken from the MachineConfiguration at the time the production dataset file is created.
LocationName	0:String
ProductName	0:String[]	These Properties are in analogy with the Properties in the JobInformationType. MouldId and NumCavities are optional in the derived CyclicJobInformationType, so here empty 0:Strings / value zero are possible.
MouldId	0:String
NumCavities	0:UInt32

NOTE: This meta data shall also be included in the production dataset file itself.

Table 115 – Possible values for Variable Components (used in the context of production datasets)

IMM	0	Injection moulding machine
ROBOT	1	Robot or handling device
TCD	2	Temperature control device
HOT_RUNNER	3	Hot runner
LDS	4	LSR dosing system
EXTRUSION_LINE	5	Complete extrusion line
EXTRUDER	6	Extruder
HAUL_OFF	7	Haull-off (as part of an extrusion line)
MELT_PUMP	8	Melt pump (as part of an extrusion line)
FILTER	9	Filter (as part of an extrusion line)
DIE	10	Die (as part of an extrusion line)
PELLETIZER	11	Pelletizer (as part of an extrusion line)
CUTTER	12	Cutter (as part of an extrusion line)
CALIBRATOR	13	Calibrator (as part of an extrusion line)
CORRUGATOR	14	Corrugator (as part of an extrusion line)
CALENDER	15	Calender (as part of an extrusion line)

NOTE: The list will be extended when further OPC UA models for other machine types are developed.
