A native Go implementation of the OPC/UA Binary Protocol for industrial automation communication. It provides client and server functionality for reading, writing, and subscribing to nodes on OPC-UA endpoints with support for security policies and encryption.
Use cases
- connect to an OPC-UA server from Go
- read and write industrial PLC data over opc.tcp
- subscribe to OPC-UA node value changes
- implement a secure OPC-UA client with SignAndEncrypt
- integrate SCADA or ICS systems with a Go application
- build an OPC-UA server in Go
When to choose
- you need OPC-UA connectivity in a Go program without CGo or external dependencies
- you want a pure-Go, MIT-licensed client for industrial data acquisition
- you need encryption and authentication support for OPC-UA connections
When to avoid
- you need a full-featured commercial-grade OPC-UA stack with certification
- your project is not in Go
- you need the complete OPC-UA feature set such as complex event handling or historical access (HA)
