Let's work together! Please, read and in best case accept CONTRIBUTING by your sign and send it via E-Mail. You could also just send a pull request or issues while testing, please!
Debugging on remote devices is important to help users. The verbose logging provides interesting points in different abstractions if IDE or console debugging is not possible.
Start debug with Node-RED in verbose (-v) mode to get a verbose logging:
DEBUG=opcuaIIoT* node-red -v 1>nodeREDIIoTOPCUA.log 2>&1
or on local Node-RED
DEBUG=opcuaIIoT* node red.js -v 1>nodeREDIIoTOPCUAServer.log 2>&1
Please, read the Wiki article
Follow the white rabbit!
Your own address space model!
With the flex server you could create your own information model with the OPC UA address space.
Learn with the examples!
The server node contains demo objects and variables to start playing with OPC UA method call, read and write operations.
see Node-RED menu (right upper corner) -> Import -> Examples -> iiot opcua
... secure reading from OPC UA servers with your own key pairs ...
... and secure writing and moving data between OPC UA servers ...
... create your own variables and objects from events ...

Reconnect via events with the Flex Connector!

That is a whole new Node-RED package started in 2017 based on the node-opcua v0.4 and the API documentation. The old copyrights by Mika Karaila are just to honor his pioneer work in the years 2015/2016 for Node-RED and OPC UA.
This is not an official product of the OPC Foundation or Plattform Industrie 4.0.
I'd like to give special thanks to Etienne Rossignon for the node-opcua packages and very special for the node-opcua-isa95 package!
