OPC UA Connector

The OPC UA Connector enables communication with OPC UA (OPC Unified Architecture) servers, providing secure and reliable access to industrial automation data and IoT devices.

Overview​

OPC UA is a platform-independent, service-oriented architecture that provides a standardized way to access industrial automation data. It's widely used in manufacturing, process control, and building automation.

Key Features​

  • Platform Independent: Works across different operating systems and devices
  • Secure Communication: Built-in security with encryption and authentication
  • Rich Data Model: Complex data structures and type definitions
  • Service-Oriented: Request/response and publish/subscribe patterns
  • Scalability: From embedded devices to enterprise systems

OPC UA Security​

The connector supports various security modes:

  • Anonymous Login: No authentication required (for testing only)
  • Username/Password: Basic authentication
  • Certificate-based: X.509 certificate authentication
  • Security Policies: None, Basic128Rsa15, Basic256, Basic256Sha256

Use Cases​

The OPC UA Connector is commonly used for:

  • Industrial Automation: Reading sensor data from PLCs and controllers
  • SCADA Integration: Connecting to supervisory control systems
  • Manufacturing Execution: Real-time production data collection
  • Building Automation: HVAC and energy management systems
  • Process Control: Chemical, oil & gas, and pharmaceutical industries
  • Predictive Maintenance: Equipment monitoring and diagnostics

Configuration​

The OPC UA Connector requires configuration of connection parameters, security settings, and node definitions to establish communication with OPC UA servers.
