Connecting XArm 6 to Node Red

Hello,

I have a inquiry regarding the robot. I want to connect the XArm 6 robot to Node red using TCP/IP but first i am required to obtain the IP from the robot. Can i use the IP of the control box, and as for the PORT number is there way to declare it inside of the blockly programming?

Can I also send the data using the IP to the nodered by adding my own code inside the XArm IDE using python?

I used the robot IP which marked on the robot control box 192.168.1.xxx, and set port as 502, seems good.

"Can I also send the data using the IP to the nodered by adding my own code inside the XArm IDE using python?"
Not quite sure, but I recommend you give a try.

Hello, i tried running a python code to connect with the XArm but when running it kept saying “No connection could be made because the target machine actively refused it” . In the code i used TCP_IP of the control box (in the picture i blanked out the last digits), port number i used any available port number, and used a buffer size of 10. Do you know ways i could go around this?

here is an example about how to get the repot data of the robot:
