Hi everyone,

I wanted to use DNP3 protocol on Node-RED in my student project, but I faced with DNP library issue.

Just, FYI (my setup is next):  
Node-RED version: v4.1.1  
Node.js version: v24.11.1  
Node Library: DNP

I just installed the DNP library by this command: `npm install node-red-contrib-dnp`

So, as I understand this DNP library is not developed yet.  
Please find attached photos for clear understanding.

Is there any other ways how can I use DNP3 protocol on Node-RED? Any other libraries?

Many thanks in advance,  
Talgat

Given that node has not been updated in 3 years I think it is probably safe to say it has been abandoned.

And the underlying packages it's is based on also appear to be no longer maintained.

[https://www.npmjs.com/package/dnp3-crc](https://www.npmjs.com/package/dnp3-crc)

[https://www.npmjs.com/package/dnp3](https://www.npmjs.com/package/dnp3)

The strongly suggests you may need to implement it yourself from the ground up.

Hello, Ben

Thank you for reply.  
I am wondering if you're already implemented any project with DNP3 on the Node-RED.  
If there is, could you please share it?

I requested from offical web-site of DNP3 documentations to try implement it by myself.  
To be presice, I just purchased a Student membership of the DNP Users Group. It costs me $0.  
I am waiting for a approval.

So, any information regarding DNP3 configuration is welcomed.

Best Regards,  
Talgat Karakulov

I'm sorry, I've never used DNP3, I just know where to look for existing nodes and working out what they depend on.
