Modbus RTU & RS485 Explained for Beginners | Communication Basics

What is Modbus RTU, and how does it work with RS485? Learn the basics of Modbus communication, including communication settings, device addressing, registers, and function codes. In this tutorial, Waqas Saeed explains the fundamental concepts behind Modbus communication in industrial automation. In this video, you will learn: • The difference between the Modbus protocol and the RS-485 electrical standard • What Modbus RTU means • Basic master/slave communication and device IDs • Baud rate, data bits, stop bits, and parity • Modbus memory areas: coils, discrete inputs, input registers, and holding registers • Read/write function codes • Register addresses, data types, and data formatting This tutorial is for students, instrumentation technicians, electricians, PLC programmers, and automation engineers who want to understand Modbus RTU over RS485. Which part of Modbus communication do you find most confusing—settings, register addresses, or function codes? Share your question in the comments.
