For geo­met­ric­al meas­ur­ing sys­tems (GMS), such as coordin­ate meas­ur­ing sys­tems, form and sur­face meas­ur­ing machines as well as multi-point meas­ur­ing machines, a VDMA work­ing group is defin­ing OPC 40210 UA for Geo­met­ric­al Meas­ur­ing Sys­tems in coordin­a­tion with the OPC Found­a­tion. The aim is to provide inform­a­tion for data trans­fer to and from geo­met­ric­al meas­ur­ing sys­tems via a uni­form inter­face that can be used by digit­al data pro­cessing sys­tems such as MES systems.

For geo­met­ric­al meas­ure­ment tech­no­logy, as the “inform­a­tion sup­pli­er“ on the qual­ity of pro­duc­tion, digit­al­iz­a­tion has a spe­cial sig­ni­fic­ance in the inter­ac­tion with oth­er pro­duc­tion sys­tems. This inter­ac­tion, which is also referred to as inter­op­er­ab­il­ity of machines and sys­tems, enables com­pan­ies to par­ti­cip­ate in new digit­al struc­tures and is a basic pre­requis­ite for new digit­al busi­ness mod­els. Through inter­op­er­able inter­faces, machines from dif­fer­ent man­u­fac­tur­ers can be effi­ciently integ­rated into exist­ing and new pro­duc­tion landscapes.

The Com­pan­ion Spe­cific­a­tion cov­ers the fol­low­ing use cases:

1. Stat­ic machine data (iden­ti­fic­a­tion of the GMS)
2. Dynam­ic machine data (cur­rent state/status of the GMS)
3. Job man­age­ment (mon­it­or­ing of meas­ure­ment routines)
4. Parts data man­age­ment (iden­ti­fic­a­tion of parts and related information)
5. Meas­ure­ment res­ults (man­age­ment of the pro­vi­sion of meas­ure­ment results)
