WebbA library package for ARDUINO acting as ModBus slave communicating through UART-to-RS485 converter. Originally written by Geabong github user. Improved by Łukasz Ślusarczyk. ModbusRTU_Slave_RS485 Author: Łukasz Ślusarczyk Maintainer: Łukasz Ślusarczyk Read the documentation Compatibility WebbThis library allows your Arduino to communicate via Modbus protocol. The Modbus is a master-slave protocol used in industrial automation and can be used in other areas, such as home automation. The Modbus generally uses serial RS-232 or RS-485 as physical layer (then called Modbus Serial) and TCP/IP via Ethernet or WiFi (Modbus IP).
