UR + Node Red Communication Problem


Does anybody figure it out how to connect with UR through NODE-RED?
I am trying to make with Modbus, and TCP/IP communication but I didn’t receive any good result.

Modbus is still loosing connection.

I am no able to figure it out how to properly send command to dashboard server.

Please help! :slight_smile:

From what I see about NODE-RED is that you can use Javascript functions, built on Node.js. Have you looked into the socket.io library to see if you can communicate that way?

No, I am quite new in this :slight_smile:

Alright, I am not sure how the NODE-RED works but using a nodeJS library like this example https://gist.github.com/tedmiston/5935757 I was able to connect to the dashboard server.

I was unable to use the socket.io library to connect to the dashboard server, I believe you have to use socket.io server to connect a client to it. So ignore the socket.io stuff.
