What is OPC UA?

OPC UA: Open Platform Communications Unified Architecture

OPC UA (IEC 62541) is a standard overseeing interoperability and data exchange for industrial communications.

It provides safe and secure means to connect supervision systems (SCADA), programmable logic controller (PLC), with actuators and field systems.

Key features of OPC UA

International standard (IEC 62541)
Open and vendor-neutral: independent of manufacturers, programming languages, and operating systems
Secure and reliable: secure communications on open networks
Interoperable, multi-platform, upgradeable
Model Based, object-oriented technology
Pub/Sub communication model

OPC UA in Industry 4.0 and IIoT

OPC UA in Industry 4.0 and IIoT OPC UA has become the standard of choice for for Industry 4.0 and the Industrial Internet of Things (IIoT). Its adoption is accelerating, particularly in response to increasing cybersecurity demands.

Across industries, aging and obsolete installations must be modernized to meet new security requirements. OPC UA provides a future-proof communication framework to support this transition.

The German Federal Office for Information Security (BSI) has positively evaluated OPC UA. In the RAMI 4.0 architecture model, the German Industry 4.0 platform mandates OPC UA for the “communication” layer.

In France, the OPC Foundation collaborates with the normalization group of Alliance pour l’Industrie du Futur to define its own reference model.
