Modbus is a serial communication protocol developed by Modicon published by Modicon® in 1979 for use with its programmable logic CONTROLLERS (PLCs). In simple terms, it is a method used for transmitting information over serial lines between electronic devices. The device requesting the information is called the Modbus Master and the devices SUPPLYING information are Modbus Slaves. In a standard Modbus network, there is one Master and up to 247 Slaves, each with a unique Slave ADDRESS from 1 to 247. The Master can also write information to the Slaves.

Modbus is an open communications protocol commonly used in INDUSTRIAL manufacturing that allows for communication between devices. With Modbus, devices from different manufacturers can be integrated in to the same device MANAGEMENT system. Modbus also enables remote read and write functionality from a device.
