This document 40719 specifies a Companion Specification for plasma surface treatment machinery.

Plasma surface treatment machinery in this context can be any existing or future plasma surface treatment machinery. The implicit and explicit information model specified by the plasma surface treatment machinery Companion Specification will be defined as a UA companion specification using OPC UA constructs for the purpose of exchanging plasma surface treatment machinery information with OPC UA applications. It shall define the required data structures, parameters, methods, state machines etc. for the communication among plasma surface treatment machinery, between plasma surface treatment machinery and supporting systems (e.g. shot blasting machinery, drying systems, conveying systems) and from plasma surface treatment machinery into higher level manufacturing systems (e.g. Manufacturing Execution System, MES), for information and diagnostic purposes and to set parameters regarding the plasma surface treatment process.
