Need Help: Connecting EcoStruxure Automation Expert with Node-RED via OPC UA

[Mohamed_hamou]

Hello everyone,

I am working on integrating EcoStruxure Automation Expert with Node-RED using OPC UA, but I am facing some challenges.

What I Have Done So Far:

• Enabled the OPC UA server in EcoStruxure Automation Expert.

• Used UaExpert to connect and retrieve variable IDs/tags.

• Followed Schneider Electric’s official YouTube tutorials.

Issues I'm Facing:

Despite these steps, I am still unable to establish a working connection with Node-RED. I would really appreciate any guidance, troubleshooting steps, or resources to help resolve this issue.

Thank you in advance for your help!

Best regards,
Mohamed

Hi @Mohamed_hamou 

As Node-RED is not part of our official supported product, i don't have official troubleshoot for that topic.

The advises i can give you is to have a step by step debug approach : 

First of all, in secure/isolated network, try to disable the OPCUA encryption ( Security Policy = None ). It will ensure that you don't have issue with Certificates, or encryption incompatibilities, and it will help you to have clear view of data packets for debug. 
Can you check (and maybe share) the logs you had both from EAE side, and Node-RED side. Can you also precise the EAE device you're using ?
Then if logs aren't enought explicit, if you're confortable with Wireshark you can intercept the packets between your nodeRed instance and EAE to indentify what's wrong here. 

Can you also precise which node (Library) you're using ?
