Job Lists – OPC UA for Plastics and Rubber Machinery

18.3 Job Lists

The jobs for a machine can be planned in an MES. This clause defines methods and events to request and send a list of planned jobs.

18.3.1 SendJobList

This Method is used to send a list of jobs available on the client to the server. The server shall support to receive at least 10 jobs.

Signature

	SendJobList ( 
		[in]	JobListElementType[]	JobList);

Table 77 – SendJobList Method Arguments

Argument	Description
JobList	Array of JobInformationType describing the available jobs in the client.

Table 78 – SendJobList Method AddressSpace Definition

Attribute	Value
BrowseName	SendJobList

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 JobList is zero) as an answer to the Event RequestJobList (see below), if no planned job is available.

The JobListElementType is defined in Table 79

Table 79 – JobListElementType Definition

Name	Type	Description
JobListElementType	structure	Subtype of 0:Structure as defined in OPC UA 10000-3
JobName	0:String	As defined in JobInformationType
JobDescription	0:String
JobClassification	0:String	Classification of the job
CustomerName	0:String	As defined in JobInformationType
ProductionDatasetName	0:String
ProductionDatasetDescription	0:String
Material	0:String[]
ProductName	0:String[]
ProductDescription	0:String[]
JobPriority	0:String	Priority of the job
PlannedStart	0:DateTime	Planned start of the job
PlannedProductionTime	0:Duration	Planned production time of the job
LatestEnd	0:DateTime	Latest end of the job

The variables JobClassification, JobPriority, PlannedStart, PlannedProductionTime and LatestEnd are additional information only for the operator to be shown on the machine control. This may help the operator to decide which jobs to download/activate. PlannedStart and LatestEnd shall be given in UTC time.

The JobClassification can e.g. be used to present a maintenance job with planned time. The possible values are user dependent and not standardized by this specification.

18.3.2 RequestJobList

The instance of JobsType can fire an Event of RequestJobListEventType (without parameters) to initiate a call of SendJobList by the client. This can e.g. be triggered by an operator who wants to see the planned jobs for his machine.

18.3.3 SendCyclicJobList

This Method is used instead of SendJobList in the case of cyclic production and includes the input parameters ExpectedCycleTime, NominalParts and NominalBoxParts.

Signature

	SendCyclicJobList ( 
		[in]	CyclicJobListElementType[]	JobList);

Table 81 – SendCyclicJobList Method Arguments

Argument	Description
JobList	Array of CyclicJobInformationType describing the available cyclic jobs in the client.

Table 82 – SendCyclicJobList Method AddressSpace Definition

Attribute	Value
BrowseName	SendCyclicJobList

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 JobList is zero) as an answer to the Event RequestCyclicJobList (see below), if no planned job is available.

The CyclicJobListElementType is a subtype of JobListElementType and adds the elements defined in Table 83.

Table 83 – CyclicJobListElementType Definition (subtype of JobListElementType)

Name	Type	Description
CyclicJobListElementType	structure	Subtype of JobListElementType
NominalParts	0:UInt64	As defined in CyclicJobInformationType
NominalBoxParts	0:UInt64
ExpectedCycleTime	0:Duration
MouldId	0:String
NumCavities	0:UInt32

NominalBoxParts, MouldId and NumCavities may be empty or zero if not used.

18.3.4 RequestCyclicJobList

The instance of JobsType can fire an Event of RequestCyclicJobListEventType (without parameters) to initiate a call of SendCyclicJobList by the client. This can e.g. be triggered by an operator who wants to see the planned jobs for his machine.
