Master RS-485 and Wi-Fi for PLC, Sensors, and IIoT Gateway Applications: From Zero to Expert
What you’ll learn
code: NISAN2026
In-depth logic of Modbus RTU (RS-485) and Modbus TCP (Wi-Fi/Ethernet) protocols
Techniques for reading/writing Real (Float) and Integer data from PLCs
Techniques for reading/writing Real (Float) and Integer data from PLCs. Bit manipulation and masking to extract data from 16-bit registers
Building a professional IIoT Gateway to bridge RTU Master and TCP Slave
Building a professional IIoT Gateway to bridge RTU Master and TCP Slave. Industrial troubleshooting for hardware conflicts and timing errors
Are you ready to explore Modbus, the “universal language” of industrial automation, combined with the power of the ESP32? This course is designed to transform you into a professional IIoT developer through hands-on practice with real hardware, including PLCs, DHT11 sensors, PCF8574 I/O expanders, and RS-485 modules.
Throughout this training, you will uncover the intricacies of both Modbus RTU and TCP protocols. You will master professional techniques ranging from solving RS-485 timing issues to splitting and merging 32-bit Float data across 16-bit registers. The highlight of the course is the IIoT Gateway project, where you will build a bridge between serial lines and Wi-Fi networks, streaming field data directly to the cloud.
Beyond simple data reading, you will experience advanced control using PCF8574 expanders for relay management and bit-masking techniques to handle multiple digital statuses within a single register. Additionally, you will learn how to implement robust auto-reconnect logic for Wi-Fi failures and static IP configurations for stable master-slave communication. We will even dive into hardware-specific troubleshooting, such as why certain modules require specific pin handling.
This training promises to unlock the “black box” of industrial communication. Whether you are an engineering student, an automation tech, or a dedicated maker, by the end of this course, you will be capable of designing your own professional industrial devices and integrating existing PLC systems into the modern IoT world!
Who this course is for:
Engineering Students: Electronics, Mechatronics, and Control Automation students looking for practical skills
Automation Technicians: Professionals wanting to connect legacy PLC systems to modern IoT solutions
IoT Developers: Software engineers looking to work with industrial wired networks
Makers: Enthusiasts wanting to upgrade their ESP32 projects to industrial standards
