I'm currently connecting from node-red to Aubobot through tcp in node. But after I connected them, it will show an intermittent state of the connection. Does anyone encounter this before?

It is specified it supports CAN bus communication. Have you considered that?  
Have a look here, might be what you are looking for

And then following Steve's suggestions you mention that you can **ping** it !  
Use the Ping node ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/7/7/77ed9d8391e5b551b9b1e4838fa4df9a6ea6b1b6.png) to do just that.  
If you get a reply in ms then it means the bot is powered on.

Or do you need additional information about the device .. not just it being powered on but if its in operation ?

If yes then you have to contact the manufacturer to provide you with the necessary documentation because i browsed through its manual and didnt find any detailed information regarding ethernet / modbus etc

> "ENOENT ping command not found"

I get this as a debug message, do you know how can I solve this.  
I read other posts saying is because my OS doesn't have that command available, so it won't work.  
I using windows on my laptop, while the Aubo robot control panel uses Ubuntu.  
I'm running node-red on my laptop.

Thats strange .. for sure the command is there for a windows OS  
and you mentioned above that you used the ping command manually without problem.

I didnt find any problem on the forum relating to this for a windows system.

Have you restated node-red after the node installation ?

I'm not really sure how to restart Node-red. Does it mean I need to log out of Node-red and log in again?  
If yes, I tried it.  
I'm running Node-red in Chrome.  
Sorry, I'm quite new here.

Just to clarify .. you are using node-red server from your laptop that is running windows ?

if yes .. then normally you have a Command Prompt open with NR running.  
You can use `Ctrl-C` or close that cmd window to stop Node-RED  
and write `node-red` to run it again

The node-red is accessible through SICK TDCE-D. So I can't run any command on the Command Prompt of my laptop

I see .. so that explains why the **ping** command may indeed be missing from that linux? based device.

I found an article that explains how to install it if you have access to the device  
**[Ping command not found](https://linuxconfig.org/ping-command-not-found-on-ubuntu-20-04-focal-fossa-linux)**

_but before that its best to consult with your technicians_
