4 Core Work­ing Groups (CWG) are involved in cre­at­ing com­mon OPC UA inter­faces for:

• organ­ic coat­ing technology
• shot blast­ing technology
• plasma sur­face technology
• clean­ing and pre­treat­ment technology

OPC 40001 UA for Machinery provides the basis for the inform­a­tion mod­els for sur­face tech­no­logy machinery.

OPC 40700 spe­cifies Gen­er­al Types for machine types that typ­ic­ally are part of a pro­duc­tion unit in which sev­er­al inter­act­ing machine types are organ­ized. The spe­cified hier­archy of Com­pon­ent, Sys­tem, Con­trol­ler and Orches­trat­or provides a com­mu­nic­a­tion concept for
inter­act­ing machine types in sur­face tech­no­logy. The Com­pan­ion Spe­cific­a­tions for Clean­ing and Pre­treat­ment Tech­no­logy, and Organ­ic Coat­ing Tech­no­logy are based on these Gen­er­al Types. As of 2025-08, the avail­able Com­pan­ion Spe­cific­a­tions are:

• OPC 40700 UA for Sur­face Tech­no­logy – Gen­er­al Types
• OPC 40701 UA for Sur­face Tech­no­logy – Clean­ing and Pre­treat­ment Technology
• OPC 40702 UA for Sur­face Tech­no­logy – Mater­i­al Sup­ply Systems

Fur­ther Com­pan­ion Spe­cific­a­tions for oth­er machine types of Organ­ic Coat­ing Tech­no­logy (applic­a­tion equip­ment, applic­a­tion booth, dip coat­ing machinery, dry­ers, etc.) will be developed.

The OCP UA inform­a­tion mod­els for the machine types of Shot Blast­ing Tech­no­logy and Plasma Sur­face Tech­no­logy have been developed on an indi­vidu­al basis.
As of 2025-08, the avail­able Com­pan­ion Spe­cific­a­tions are
• OPC 40718 UA for Sur­face Tech­no­logy – Shot Blast­ing Technology
• OPC 40719 UA for Sur­face Tech­no­logy – Plasma Sur­face Technology
