ReceiveJobOrder - Defines the ReceiveJobOrder Method which receives job orders and job order commands.

JobOrderList - Defines a read-only list of job order information available from the server. The information returned is defined by the server and may be a complete copy of a received job order or may be just the IDs of the job orders. If there are no job orders available from the server, then this may be null.

WorkMaster – Defines a read-only set of work master IDs that may be specified in a job order, and the read-only set of parameters that may be specified for a specific work master. If there are no restrictions on what work master IDs can be sent with a job order, then this may be null.

MaterialClassID - Defines a read-only set of Material Classes IDs that may be specified in a job order. If there are no restrictions on what Material Classes IDs can be sent with a job order, then this may be null.

MaterialDefinitionID - Defines a read-only set of Material Classes IDs that may be specified in a job order. If there are no restrictions on what Material Classes IDs can be sent with a job order, then this may be null.

EquipmentID - Defines a read-only set of Equipment Class IDs and Equipment IDs that may be specified in a job order. If there are no restrictions on what Equipment IDs can be sent with a job order, then this may be null.

PhysicalAssetID - Defines a read-only set of Physical Asset Class IDs and Physical Asset IDs that may be specified in a job order. If there are no restrictions on what Physical Asset IDs can be sent with a job order, then this may be null.

PersonnelID - Defines a read-only set of Personnel IDs and Person IDs that may be specified in a job order. If there are no restrictions on what Personnel IDs can be sent with a job order, then this may be null.

6.2.1.2 ReceiveJobOrder Method

This Method receives job orders and job order commands.

The signature of this Method is specified below. Table 13 and Table 14 specify the Arguments and AddressSpace representation, respectively.

Signature

ReceiveJobOrder (

[in]ISA95JobOrderCommandEnumJobOrderCommand

[in]ISA95JobOrderDataType JobOrder

[out]UInt64 ReturnStatus

);

Table 13 – ReceiveJobOrder Method Arguments

Argument	Description
JobOrderCommand	Contains the command to the Information Receiver on the action to be taken on the job order. For example, it may contain a Start command to start a stored job order or a Cancel command to cancel an un-started Job Order.
JobOrder	Contains information defining the job order with all parameters and any material, equipment, or physical asset requirements associated with the order.
ReturnStatus	Returns the status of the method execution.

Method Result Codes are defined as part of the Call service (see OPC 10000-4, Table 56, and Table 57).

6.2.2 ISA95JobResponseProviderObjectType

6.2.2.1 Overview

The ISA95JobResponseProviderObjectType contains a method to receive unsolicited job response requests as illustrated in Figure 5.

RequestJobResponse – Defines the ISA95JobResponseRequest Method which receives requests for Job Responses.

The ISA95JobOrderReceiverObjectType with the ReceiveJobOrder method may be paired with an ISA95JobResponseProviderObjectType and the RequestJobResponse method, to send a Job Order and query for a JobResponse. This transaction is illustrated in Figure 6.

6.2.2.2 RequestJobResponse Method

This method is used to return Job Responses for unsolicited requests for responses from a job order.

The signature of this Method is specified below. Table 16 and Table 17 specify the Arguments and AddressSpace representation, respectively.

Signature

RequestJobResponse (

[in]String JobOrderID

[in] ISA95JobOrderStateEnum JobOrderState

[out]ISA95JobResponseDataType[]JobResponse

[out]UInt64 ReturnStatus

);

Table 16 – RequestJobResponse Method Arguments

Argument	Description
JobOrderID	Contains an ID of the job order, as specified by the method caller. This argument shall be null if the JobOrderState is defined.
JobOrderState	Contains a job status of the JobResponse to be returned. This argument shall be null if the JobOrderID is defined.
JobResponse	Contains information about the execution of a job order, such as the current status of the job, actual material consumed, actual material produced, actual equipment used, and job specific data.
ReturnStatus	Returns the status of the method execution.

If both JobOrderID and JobOrderState or neither are specified then an “Invalid Request” error shall be returned.

Method Result Codes are defined as part of the Call service (see OPC 10000-4, Table 56, and Table 57).
