Eclipse Milo is an open-source Java implementation of the OPC UA (IEC 62541) protocol, providing a high-performance communication stack plus client and server SDKs. It targets OPC UA 1.05 and is published to Maven Central.
Use cases
- connect to an OPC UA server from a Java application
- build an OPC UA server in Java
- read and write industrial PLC data over OPC UA
- implement secure OPC UA client-server communication
- integrate factory floor equipment with a Java backend
- test against a public OPC UA demo server
When to choose
- you need a mature, Eclipse-hosted OPC UA stack for the JVM
- you want both client and server SDKs in one project
- you need OPC UA 1.05 support with security features built in
When to avoid
- you need OPC UA in a non-JVM language like C++, Python, or .NET
- you only need a lightweight protocol like MQTT instead of full OPC UA
- you require runtime compatibility with Java versions older than 17
