What is Modbus RTU?

Modbus was originally developed by Modicon and today, it is managed by the Modbus User Organization. Modbus is an open Master/Slave application protocol, that can be used on several different physical Layers. Modbus is an application-layer messaging protocol, positioned at level 7 of the OSI model.

It provides client/server communication between devices connected on different types of buses or networks. Modbus-RTU (Remote Terminal Unit) means that the Modbus protocol is used on top of a serial line with an RS-232, RS-485 or similar physical interface.

Numerous automation systems have Modbus-RTU interfaces for communication. Modbus devices are certified by the Modbus User Organization for interoperability and conformance to the Modbus specification.
