8 Additional Information about the Job Management

8.1 Overview

OPC 10031-4 defines mechanisms to add job order information using the 6:ISA95JobOrderDataType and mechanisms getting the result or current status of the job order using the 6:ISA95JobResponseDataType. Both DataTypes define arrays of properties of a job order: general, personal, equipment, physical assets, and material. The 6:ISA95JobOrderDataType uses the general properties to describe the job order and the other properties to define the requirements, whereas the 6:ISA95JobResponseDataType uses the general properties to describe the output and the other properties to provide the information what has been used.

OPC 40001-3 UA for Machinery Job Management standardizes some of those parameters, which are application-specific from the view of OPC 10031-4.

The guidelines and extensions specified in this section are designed to complement the foundational models, providing a structured framework for implementation. The optional elements (e.g., fields or parameters) of the OPC 10031-4 or OPC 40001-3 may be used as defined.

8.2 Management of WorkMaster and WorkMaster files

The WorkMasterID field of the 6:ISA95JobOrderDataType contains the information about the work master (e.g., the cutting tool file). The field ID is an identification of the work master. This should be used to identify a work master across different OPC UA Servers and must be unique in its scope (e.g., company unique).

This specification uses the 0:FileSystem folder to manage (e.g., store/retrieve files) the work master files on the server. To connect the WorkMasterID with the file additional predefined key-value pairs for 6:ISA95WorkMasterDataType.Parameter are defined in Table 20.

LocalPathStringContains the file path on the OPC UA server. This must be identical with the relative path of the BrowsePath.--
FileNodeId0:NodeIdContains the NodeId of the object of the file.--
FileFormatFileFormatDataTypeDefines the file format of the work master file. This is used to ensure compatibility between the work master and the machine.--
