First Steps with Modbus
Modbus is the language most field devices already speak: energy meters, drives, sensors, SCADA systems and other PLCs. This course teaches how it works and how to implement it on Industrial Shields PLCs, as master or slave, over RS-485 (Modbus RTU) and Ethernet (Modbus TCP).
What you will be able to do
- Explain coils, discrete inputs, input registers and holding registers, and choose the right function code.
- Wire a Modbus RTU bus over RS-485 and a Modbus TCP network.
- Implement a Modbus master and slave with the Arduino IDE (Arduino and ESP32 PLCs).
- Implement them on Raspberry PLCs with Python, Node-RED and C.
Who it is for
System integrators and engineers who connect PLCs with field devices or SCADA systems. Basic programming knowledge is enough.
