Hello Madhumati,

this forum gives no support at all for 3rd party software such as Node-RED. It is a user software. Also there is no support for Node-RED nodes.

By the way ... we don't know this node named "node-red-contrib-opcua". It is not made by Hilscher and is open source and maintained in the community here: https://flows.nodered.org/node/node-red-contrib-opcua

If you need help concerning this node you have to visit this site and search for helping information such as examples or sample configuration.


RE: OPC UA - Armin@netPI - April-30th-2019

Hello Madhumati,

we have now released a containerized reference implementation of the open source OPC UA server stack "open62541" maintained at https://open62541.org here https://hub.docker.com/r/hilschernetpi/netpi-opcua-server

With this implementation you need just an Nodeset XML file containing your OPC UA objects and feed the container web application with it and then it transforms it into a running OPC UA server in just some minutes.

This conatiner is just an example implementation and shows in principle of how the general procedure looks like how to deal with the open source stack. In no way it is a ready-to-use implementation and should be used in productive operations.
