Intro to Modbus

Modbus is a serial communications protocol originally published by Modicon (now Schneider Electric) for use with its programmable logic controllers (PLCs). Modbus has become a de facto standard communication protocol and is now a commonly available means of connecting industrial electronic devices.

Modbus enables communication among many devices connected to the same network and is often used to connect a supervisory computer with a remote terminal unit (RTU) in supervisory control and data acquisition (SCADA) systems.
