Modbus allows for communication between many devices
connected to the same network, for example a system that
measures temperature and humidity and communicates the
results to a computer. Modbus is often used to connect a
supervisory computer with a remote terminal unit (RTU) in
supervisory control and data acquisition (SCADA) systems.
