WebSep 12, 2024 · Modbus RTU (Remote Terminal Unit) is one of the two transmission modes defined in the original Modbus specification. The two modes are Modbus RTU and ASCII and are both designed to be used with serial devices supporting the RS232, RS485, and RS422 protocols. Modbus is an open protocol that supports serial devices that use the RS232/RS485/RS422 protocols. Its simplicity and the fact that manufacturers can incorporate it into their products at no charge has helped it become the most popular method of connecting industrial electronic devices.
