OPCUA

A native Go implementation of the OPC/UA Binary Protocol.

You need go1.11 or higher. We test with the current and previous Go version.

CircleCI GoDoc GolangCI License Version

Quickstart

# make sure you have go1.11 or higher

# install library
go get -u github.com/gopcua/opcua

# get current date and time 'ns=0;i=2258'
go run examples/datetime/datetime.go -endpoint opc.tcp://localhost:4840

# read the server version
go run examples/read/read.go -endpoint opc.tcp://localhost:4840 -node 'ns=0;i=2261'

# get the current date time using different security and authentication modes
go run examples/crypto/*.go -endpoint opc.tcp://localhost:4840 -cert path/to/cert.pem -key path/to/key.pem -sec-policy Basic256 -sec-mode SignAndEncrypt

# checkout examples/ for more examples...

Disclaimer

We are still actively working on this project and the APIs will change.

We have started to tag the code to support go modules and reproducible builds but there is still no guarantee of API stability.

However, you can safely assume that we are aiming to make the APIs as stable as possible. :)

The Current State was moved to the Wiki.

Your Help is Appreciated

If you are looking for ways to contribute you can

  • test the high-level client against real OPC/UA servers
  • add functions to the client or tell us which functions you need for gopcua to be useful
  • work on the security layer, server and other components
  • and last but not least, file issues, review code and write/update documentation

Also, if the library is already useful please spread the word as a motivation.

Authors

If you need to get in touch with us directly you may find us on Keybase.io but try to create an issue first.
