Many thank

I was interested in this protocol also.  
There doesnt seem to be a Node-red Node for it .. and even on npm if you search there is not much results of nodejs packages for it.

There is only one project that seems to be under development :

> **[GitHub - intrahouseio/ih-lib60870-node](https://github.com/intrahouseio/ih-lib60870-node/)**
>
> Contribute to intrahouseio/ih-lib60870-node development by creating an account on GitHub.

So using a Function node and its [functionExternalModules](https://nodered.org/docs/user-guide/writing-functions#using-the-functionexternalmodules-option) option you could try loading the library  
and trying the examples the developer of the library has [here](https://github.com/intrahouseio/ih-lib60870-node/tree/main/examples)

Alternatively .. use an Protocol Gateway / converter RTU like an [Elseta WCCLite](https://elseta.com/products/rtus/wcc-lite/) that supports IEC60870-5-104 and send your data to Node-red with MQTT or Modbus

@Boy_co_don If you intend on trying what Andy has suggested, this article has a bit more info on using modules in a function node:

> **[Use any npm module in Node-RED • FlowFuse](https://flowfuse.com/blog/2023/06/import-modules/)**
>
> Node-RED has an incredibly rich resource of integrations available, but sometimes you need that little extra. This shows you how.
