The definition which product (family) is produced is done by a job group. This defines which equipment, production dataset and materials are used and which configuration parameters (e.g. width, length of foil) are offered. The concrete products (roll of film with defined width and length) are models as jobs inside this group.

NOTE: Examples for different combinations of jobs are presented in the Annex.

The NodeVersion Property as defined in OPC UA Part 3 is used to inform the client about model changes. Here it informs about added or removed instances of JobGroupType.

This is a placeholder for the job groups (see 0). When instances are created the BrowseNames shall be “JobGroup_<Nr>” where <Nr> is a three-digit number with leading zeros, starting with “001”.

This method adds a new job group with the needed Properties.

Id of the job. It shall be unique inside the relevant job group. Two jobs inside different job groups may have the same Id.

Description of the job.

Name of the customer for that the job is produced.

Id of the product produced by the job.

Description of the product produced by the job.

Strand is used when several products (two pipes is parallel, foil cut into several smaller foils) are produced in parallel. When only one product is produced at the same time, the value is always 1.

Planned sequence when the job group contains multiple job for one strand. When there is only one job for a string in the production group the value is always 1.

Array for the configuration of the job by setting values for the offered configuration parameters. The ParameterSettingType is defined in OPC 40083. If an entry in the ConfigurationParamters Array in the job group has no corresponding entry in the ParameterSetting Array, the default value is used.

Set output of the job. The output is always counted in units, where a unit can be a piece of pipe/profile, roll of film, bag of compound, but also a defined bundle (e.g. one unit consist of 4 bags). What a unit is, may be configurable by the configuration parameters.

Size of a production lot. This used to control the

  • frequency of the Events of LotFinishedEventType (see 9.3.19)
  • production of different jobs in a group: When LotSize is reached, the next job in the group is produced (see examples in Annex).

Status of the job. The JobStatusEnumeration is defined in OPC 40083.

Indication if the produced product has a good quality. Can be set by the machine or the operator. When it changes from true to false the line control shall create an alarm.

Which lot (number) is currently in production.

Optional name for the actual lot.

These Variables represent the total number of produced (finished) units and the numbers of good, bad and test sample units in the current job. (see explanation above for unit in SetOutput).

Average output rate of the job in units per hour.

NOTE: The three events JobStatusChanged, UnitFinished and LotFinished may be fired simultaneously. E.g. when a job is finished, then the status is changed, the last product is finished as well as the last lot. If the job is the last in the job group, the JobGroupStatusChanges event will be fired in addition. However, the client decides which EventTypes are subscribed.
