What Is The Modbus?
Modbus is a serial communications protocol originally published by Modicon (now Schneider Electric) in 1979 for use with its programmable logic controllers (PLCs). Modbus is often used to connect a supervisory computer to a remote terminal unit (RTU) in supervisory control and data acquisition (SCADA) systems.
