OPC 40001 UA for Machinery

The OPC 40001 series is applicable for the entire machine building industry.

It con­tains vari­ous build­ing blocks for machinery that allow use cases across dif­fer­ent types of machines and com­pon­ents of machines. These build­ing blocks can either be used in oth­er com­pan­ion spe­cific­a­tions or dir­ectly in an inform­a­tion model.

The first ver­sion was pub­lished in 09/2020 and was one of the first OPC UA com­pan­ion spe­cific­a­tions to be fully endorsed by the umati com­munity. Recently, the ver­sion was updated to address addi­tion­al use cases and will con­tin­ue to be updated in the future.

The imple­men­ted use cases for the iden­ti­fic­a­tion of machines and com­pon­ents form the basis for the “Plug & Work” tar­get image, as aggreg­ates from a wide range of indus­tries can be iden­ti­fied in the same way and enable machine- and man­u­fac­turer-inde­pend­ent recog­ni­tion between diverse net­work participants.

Part 1 cov­ers these use cases:

  • Machine Iden­ti­fic­a­tion and Nameplate 
  • Find­ing all Machines in a Server 
  • Com­pon­ent Iden­ti­fic­a­tion and Nameplate 
  • Find­ing all Com­pon­ents of a Machine 
  • Machinery State
  • Cur­rently ongo­ing: Job Man­age­ment and Pro­cess Values

The highest level of inter­op­er­ab­il­ity is achieved through cross-domain inform­a­tion mod­els. One such inform­a­tion mod­el is the OPC UA Com­pan­ion Spe­cific­a­tion OPC UA for Machinery.

The “Machinery State” mod­ule paves the way for vari­ous use cases like Machine Mon­it­or­ing and KPI Cal­cu­la­tions. Machine avail­ab­il­ity can eas­ily be determ­ined, res­ult­ing in high added value – espe­cially in pro­duc­tion where machines from dif­fer­ent indus­tries are used.

OPC 40001–1 / VDMA 40001–1 was developed under the umbrella of VDMA, the Mech­an­ic­al Engin­eer­ing Industry Asso­ci­ation, in a Joint Work­ing Group with the OPC Found­a­tion. It fol­lowed an ini­ti­at­ive by a num­ber of tech­no­logy-spe­cif­ic first-mover stand­ard­iz­a­tion groups from dif­fer­ent sec­tors of the machine build­ing industries.
