Analog button trigger LED on another Arduino Uno Wifi board

Hai, I am new here,

Can someone help me with my project?

I am creating Andon System (if familiar) by using Arduino Uno Wifi Development Board (6 units)

I need to know how to trigger LED on another Arduino Board by using fixed IP address?

eg:see attachment.

When I press button ( pin 7 )on Arduino Board 192.168.1.4 it will trigger ON LED for Arduino Board 192.168.1.4 through pin 13 and trigger ON LED for Arduino Board 192.168.1.5 until Arduino Board 192.168.1.9 through pin 12.

Please help me for this project.
