Hello Kartik,

I found this guide on how to connect Node-Red to an OPC-UA server. I assume the steps would be similar to connect to Ignition's OPC-UA server.

> **[node-red-contrib-opcua](https://flows.nodered.org/node/node-red-contrib-opcua)**
>
> A Node-RED node to communicate via OPC UA based on node-opcua library.

As for your Ignition OPC-UA server settings I suggest setting them up as the following, this would make your OPC endpoint(opc.tcp://(GatewayIP):62541/discovery).

Hi there.  
Just what to share with others.  
I could connect without certificates, only with a username and password.  
I create my own "pi" user for that.  
P.S. Do not forget the firewall settings.

I highly recommend the Ignition-NodeRED module route (if installing 3rd party module is permitted on the Ignition gateway). The websocket connection has been very reliable (and more performant) then the opc connections I've tested with:

> **[GitHub - IgnitionModuleDevelopmentCommunity/IgnitionNode-RED: Adds support for Node-RED](https://github.com/IgnitionModuleDevelopmentCommunity/IgnitionNode-RED)**
>
> Adds support for Node-RED

Otherwise, I was able to establish a secure connection (after exchanging certs, etc.).
