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

Debug Options

Please, read the Wiki article

Klaus Landsdorf

That is a whole new Node-RED package started in 2017 based on the node-opcua v0.1.x 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. It is just to provide OPC UA to Node-RED based on node-opcua.

Contribution node-opcua

I'd like to give special thanks to Etienne Rossignon for the node-opcua packages and very special for the node-opcua-isa95 package!
