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.
| ID | DataType of Value | Description | EngineeringUnits | Subparameters |
|---|---|---|---|---|
| LocalPath | String | Contains the file path on the OPC UA server. This must be identical with the relative path of the BrowsePath. | - | - |
| FileNodeId | 0:NodeId | Contains the NodeId of the object of the file. | - | - |
| FileFormat | FileFormatDataType | Defines the file format of the work master file. This is used to ensure compatibility between the work master and the machine. | - | - |
