• Standardised framework for the exchange of data and services

• Open manufacturer and system independent standard

• Developed by OPC Foundation (non-profit organization)

• Very good experiences in practical application of members

• Cost-effective procurement for important programming environments (C++,

C#, Java)

• Fulfils all present requirements with

Client/Server-Architecture, Semantic Data

Description, Security

What is OPC UA?

Advantages of standardised

data exchange

For machine manufacturers

» Definition of which data is exchanged is which

form

No in-house developments necessary

Less coordination effort between partners

For plant operators

» Simpler combination of machines when

components of different manufacturers are able

to communicate with each other

Lower integration and configuration effort

Seite 6 | 2018-11-08

VDMA

Past/current interfaces between machines:

EUROMAP plugs

Standardised interfaces

» For specific machine combinations

(e.g. injection moulding machine – robot, extruder – downstram equipment)

» Field level (release / safety signals)

» Uniform plug connectors

» Hardware based signal transmission

» Limited possibilities of data exchange

» No extensibility

Development of the information model

What? How?

Which functionality should the

interface contain?

Modeling in OPC UA

Formation of semantic blocks objects

Knowledge of machines and

processes necessary

Knowledge of OPC UA necessary

(general programming skills helpful)

Exchange of data

(Which data, number of individual

parameters, real time?)

Definition of parameters: names, data types (variables,

fields, structures, objects)

Client / server vs. Pub-Sub

control features Definition of methods: input and output parameters

Notifications:

trigger condition,

data to be transmitted

Definition of events: assignment to objects
