OPC-UA

What is OPC UA​

OPC-UA (OPC Unified Architecture) is a new generation communication standard protocol in industrial automation, gradually replacing traditional OPC protocols. It provides a secure, reliable, platform-independent industrial communication solution. ThingsPanel achieves seamless integration with industrial devices by integrating OPC-UA device connectivity services, providing strong support for industrial IoT applications.

OPC-UA is a machine-to-machine communication protocol for industrial automation with the following features:

  1. Platform Independence:

    • Cross-platform deployment
    • Operating system independent
    • Supports multiple programming languages

  2. Security:

    • Built-in encryption
    • Certificate authentication
    • Data transmission security
