In this video, I will show you how to control the FX3U PLC using ESP32 directly controlled through RS485 and remotely controlled from PC using UDP protocol thru port 3333.

Also show you how to read the Analog Input from FX3U PLC, and how to control the stepper motor.

You can get the ESP32 source code from here:
