How to get the IP address of industrial computer

Before teleoperation, we need to fill in the IP address of the industrial computer running the Master node in the .bashrc file. Only when the IP address is written correctly, the nodes on the two computers can communicate normally.

Option 1: Read on IPC

Connect the industrial computer to the monitor and keyboard, open the terminal, and enter:

ifconfig

The following information will be displayed

Generally the industrial computer is connected to the wireless network, it mainly depends on the information on the wlan side (note: the name of the wireless network card of some computers is not wlan, but wlp60s0). Find the inet addr in the corresponding information section: xxx.xxx.xxx.xxx is the corresponding IP address.

Option 2: Obtaining an IP address on the web page

If you are using a wireless network established by a wireless router and you are the administrator of the router, it is recommended that you use this method, because you can know the IP without connecting the monitor and keyboard. Method: Log in to the web page for setting up the wifi network in the browser, such as 192.168.1.1, tplogin.cn, etc., you can log in to the back end of the router through the browser, and see the IP address of the industrial computer by viewing the information of the connected device.
