2.3 Communication ports Each Idec-Modbus Converter unit has two communication ports . Description of each is given in following topics. ¾ Com port1: This port is RS232C port and is used for configuration of Idec-Modbus Converter. Same port can be used for PLC communication after proper configuration.
Nov 02, 2019 · OVERVIEW • MODBUS Protocol is a messaging structure created by MODICON company to connect PLC to programming tools. • It is now widely used to establish master-slave communication between intelligent devices. • MODBUS is independent of the physical layer.
Arduino Modbus Library This 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.
