OPC UA Server

This section describes how to create and configure an Open Platform Communications Unified Architecture (OPC UA) Server on a PCMM2G controller and how to verify communication using various OPC UA client applications.

• This is the successor of the former OPC specifications.
• It is a standardized machine to machine communication protocol for industrial automation.
  • It is developed and maintained by the OPC Foundation.
• When configured, the OPC UA driver enables secure communication using digital certificates and data encryption.

OPC UA Server Overview

The OPC UA Server is a platform-independent, service-oriented architecture designed for secure and reliable data exchange in industrial automation environments.

The OPC UA Server acts as a central communication hub, enabling seamless interoperability between devices, systems, and applications.

Key Features

• Cross-Platform: Operates across Windows, Linux, and embedded systems.
• Data Modeling: Supports complex data structures and semantic information.
• Scalability: Suitable for small devices to enterprise-level systems.
• Security: Built-in encryption, authentication, and user access control.
• Standardized Communication: Facilitates consistent data exchange across heterogeneous systems.

Typical Use Cases

• Industrial IoT applications
• Machine-to-machine communication
• Remote monitoring and diagnostics
• SCADA and MES integration
