Simple OPC-UA GUI client.

Written using freeopcua python api and pyqt. Basic functionnalities are implemented including subscribing for data changes and events, write variable values listing attributes and references.

Screenshot

What works:

  • connecting and disconnecting
  • browsing with icons per node types
  • showing attributes and references
  • subscribing to variable
  • make available on pip: sudo pip install freeopcua-client
  • remember connections and show connection history
  • subscribing to events
  • write variable node values
  • gui for certificates
  • gui for encryption

TODO (listed after priority):

  • detect lost connection and automatically reconnect
  • gui for loging with certificate or user/password (can currently be done by writting them in uri)
