OPC UA DataTypes – OPC UA for Additive Manufacturing

10 OPC UA DataTypes

This structure contains the information related to a job run. The structure is defined in Table 23.

Table 23 – RunInfoDataType Structure

Name	Type	Description	Optional
RunInfoDataType	structure	Subtype of 0:Structure defined in OPC 10000-5
CurrentLayer	0:UInt32	Counter that increases after each completed layer of the job run. This counter does not give any indication about the part quality.	True
Identifier	0:String	Identifier of the job run. This identifier is used to ensure an assignment of parts and job run(s). For this reason, the identifier shall be unique.	False
State	9:ISA95StateDataType	State information on job run level. This state works additionally to the overall job status.	False
RemainingTime	0:Duration	Describes the remaining process time in seconds.	True

Its representation in the AddressSpace is defined in Table 24.

This enumeration indicates the function of a specific feedstock.

The FeedstockFunction enumeration is defined in Table 26.

Table 25 – FeedstockFunction Items

Name	Value	Description
Undefined	0	The function of the feedstock is unknown.
Main	1	The feedstock is used for production and is part of the finished part.
Ancillary	2	The feedstock is used for production but removed before the part is finished.
Consumable	3	The feedstock is consumed during the production e.g., process gas.

Its representation in the AddressSpace is defined in Table 27.
