18 JobsType

This clause defines ObjectsTypes for managing production jobs on the machine and for information on their status including process parameters (temperatures, pressures…).

18.1 JobsType Definition

This ObjectType represents the jobs (order to produce parts/process material) stored on the machine. It is formally defined in Table 72.

ActiveJob represents the job that is currently active on the machine.

JobInPreparation represents a job that is in preparation. Background: Some manufacturers use two "layers" for job information in their control systems: one active information layer and one for preparation. So, during a running job, inputs for the following job are possible. By pressing a button on the control panel, data from the prepared job information can be set active.

ActiveJobValues represents the status of the current job. See 18.4.

SendJobList sends a list of jobs available on the client to the server. Can be triggered by the machine by the event RequestJobList (see 18.3.2). For cyclic processes SendCyclicJobList and RequestCyclicJobListEventType are used.

NOTE: A method SendContinuousJobList for continuous processes will be added in the future.

18.2 JobInformationType

18.2.1 JobInformationType Definition

This ObjectType represents the data of the job. It is formally defined in Table 73.

The JobInformationType is abstract. A derived concrete type, which includes a method for writing the Properties, must be used (e.g. CyclicJobInformationType).

NOTE: A second subtype ContinuousJobInformationType will be added in the future.

18.2.2 JobName

The JobName Property represents the name of the job.

18.2.3 JobDescription

The JobDescription Property represents the description of the job.

18.2.4 CustomerName

The CustomerName Property represents the name of the customer for that the job is produced.

18.2.5 ProductionDatasetName

The ProductionDatasetName Property represents the name of the production dataset which is needed for the job.

18.2.6 ProductionDatasetDescription

The ProductionDatasetDescription Property includes an additional description of the production dataset which is needed for the job.

18.2.7 Material

The Material Property is an Array of material names used for the job.

18.2.8 ProductName

The ProductName Property is an Array of product names produced by the job. (More than one possible with multiple cavities)

18.2.9 ProductDescription

The ProductDescription Property is an Array of descriptions of the products produced by the job.

18.2.10 ContinueAtJobEnd

The ContinueAtJobEnd Property indicates if the machine continues the production even if the nominal output has been reached.

18.2.11 CyclicJobInformationType

Additional information on a job for cyclic production (e.g. injection moulding) are stored in the CyclicJobInformationType. It extends the JobInformationType. It is formally defined in Table 74.

18.2.11.1 NominalParts

The NominalParts Property indicates the total number (sum of all cavities) of parts that shall be produced by the job.

18.2.11.2 NominalBoxParts

In some productions, the parts are placed in several boxes. The NominalBoxParts Property indicates the number of parts that shall be put into one box.

NOTE: A "box" can be any kind of container like stacking box, lattice box, bag… .

18.2.11.3 ExpectedCycleTime

The ExpectedCycleTime Property indicates which cycle time is calculated for the job.

18.2.11.4 MouldId

The MouldId Property represents the Id of the Mould used for the job.

NOTE: Although a machine can be equipped with several moulds, one job is always related to a single mould. This is why MouldId is not an array here.

18.2.11.5 NumCavities

The NumCavities Property indicates the number of cavities in the Mould used for production.

18.2.11.6 SetCyclicJobData

With this Method the MES sets the job data for cyclic jobs.

Input arguments are all Properties of the CyclicJobInformationType.

Signature

	SetCyclicJobData (
		[in]	0:String	JobName
		[in]	0:String	JobDescription
		[in]	0:String	CustomerName
		[in]	0:String	ProductionDatasetName
		[in]	0:String	ProductionDatasetDescription
		[in]	0:String[]	Material
		[in]	0:String[]	ProductName

		[in]	0:UInt64	NominalBoxParts
		[in]	0:Duration	ExpectedCycleTime
		[in]	0:String	MouldId
		[in]	0:UInt32	NumCavities);

When optional Properties in CyclicJobInformationType (e.g. NominalBoxParts) are not used, the arguments have to be empty or equal to zero.

18.2.11.7 RequestCyclicJobWrite

The Event RequestCyclicJobWriteEventType is used to initiate a call of the SetCyclicJobData Method by the client.

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);

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

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);

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.

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.
