WebThis library implements the Modbus protocol over two different types of transport: serial communication over RS485 with RTU (Remote Terminal Unit) or Ethernet and WiFi communication with TCP protocol. There are a few differences in the APIs depending on the transport, but the majority of the functions are the same for both. Web21 mei 2024 · This library is designed to use an Arduino as a Modbus master to communicate with a sensor/slave via the Modbus RTU communication protocol. It's specifically written with lots of "higher-level" functions to help out users who are largely unfamiliar with the Modbus protocol and want an easy way to get information from a …
