OPC 40451 UA for Industrial Joining Technologies

The OPC 40450 for Indus­tri­al Join­ing Tech­no­lo­gies is an ini­ti­at­ive to cre­ate com­mon OPC UA inter­face for join­ing tech­no­lo­gies. The OPC 40451for Tight­en­ing is the 1st detailed com­pan­ion spe­cific­a­tion for a spe­cif­ic join­ing tech­no­logy, in this case tightening.

The OPC 40451 for Industrial Joining Technologies is an initiative to create common OPC UA interface for joining technologies.

The VDMA Indus­tri­al Join­ing Tech­no­lo­gies ini­ti­at­ive, launched in May 2019, pub­lished Release 1 of the OPC 40451–1 Tight­en­ing Com­pan­ion Spe­cific­a­tion in
Octo­ber 2021, and Release 2 was pub­lished in March 2024. At the same time, the OPC 40450 for Indus­tri­al Join­ing Tech­no­lo­gies was released. This ver­sion handles most of the man­age­ment data, ensur­ing the same data struc­ture is avail­able for dif­fer­ent join­ing pro­cesses. As a joint work­ing group, the ini­ti­at­ive is organ­ized by VDMA Auto­mated Solu­tions and sup­por­ted by the OPC Found­a­tion. Para

The aim of the ini­ti­at­ive is to cre­ate stand­ard inter­faces for join­ing tech­no­lo­gies such as Tight­en­ing, Riv­et­ing, Glu­ing, Press­ing etc. The first release of the ini­ti­at­ive was to cov­er the spe­cif­ic Tight­en­ing use cases along with com­mon ele­ments at the join­ing level.

The core work­ing group that is devel­op­ing the spe­cific­a­tion con­sists of 15+ experts from 13 companies.

The fol­low­ing are the use cases covered in Release 1, pub­lished in March 2024:

  • Asset Man­age­ment and Con­di­tion Monitoring
    • Over­view and iden­ti­fic­a­tion, mon­it­or­ing of an asset.
    • Set of meth­ods to man­age an asset. Example: Enable Asset, Dis­con­nect Asset, etc.
  • Res­ult Management
    • Stand­ard defin­i­tion of the Res­ult includ­ing Steps, Traces, Errors.
    • Stand­ard access to Res­ult using Events, Meth­ods and AddressSpace.
  • Event Man­age­ment
    • Stand­ard event and con­di­tion pay­load from a join­ing system.
    • Stand­ard set of con­di­tion classes to cat­egor­ize or fil­ter vari­ous types of events from a join­ing system.
  • Join­ing Pro­cess Management
    • Set of meth­ods and data types to man­age a join­ing pro­cess. Example: Select Pro­cess, etc.
  • Joint Man­age­ment
    • Set of meth­ods and data types to man­age a joint. Example: Send Joint, Select Joint, etc.
