Modbus has become a widely used field bus throughout the world since its introduction in 1979. It is a serial-based communication protocol and has two serial variants - Modbus RTU and Modbus ASCII. It is often used in conjunction with other field buses via field bus gateways but is ideal in networking controllers, sensors, actuators and binary terminal devices in the automation environment in a cost-effective manner. With the advent of Ethernet networking, MODBUS was extended to this medium and MODBUS TCP was added to the portfolio.
The course begins with an introduction to what Modbus is and its history. We see where Modbus fits in as a digital communications system and the additional flexibility of Modbus TCP. For distributed I/O we see how it provides simplification and easy expansion of both digital and analogue signals.
