Modbus RTU is an open, serial (RS-232 or RS-485) protocol based on master/slave or client/server architecture. In fact, µC/Modbus allows you to have a combination of up to 250 master or slave ports from a single target system! µC/Modbus-S indicates that your product contains the Modbus slave implementation of µC/Modbus and, µC/Modbus-M indicates that your product contains the Modbus master implementation of µC/Modbus. ) For these reasons, Modbus is very good at providing you with a polled and contention-less network. It was developed in 1979 for use with Programmable Logic Controller (PLC) devices, and is now widely used for connecting many types of industrial electronic devices connected on different types of networks. It was originally designed in the mid-1970s by Modicon as a way to link intelligent devices with PLCs using a simple master/slave concept. The lower serial port labelled “OIO” of the Adlink Edge Smart Gateway supports both RS232 and RS485 serial modes. In simple terms, it is a method used for transmitting information over serial lines between electronic devices. This document covers a set of application that moves I/O data in a SY/MAX. , phone 1-800-522-6277, 24 hours.
