  • Page 4: Introduction

    1. Introduction The MDC-700 series module is a Modbus Data Concentrator which can concentrate data from several Modbus RTU slave devices with RS232/RS-485 interface and allows Modbus TCP masters to read/write data via Ethernet/LAN. The Modbus master can use one Modbus command to get all data on those Modbus RTU slave devices via the MDC-700 concentrator.
  • Page 5 Features  HTML5 Web-based User Interface HTML5 is the latest version of the HTML markup language. It is supported by most current browsers including Mozilla Firefox, Apple Safari, Google Chrome and so on. For the reason, the Web-based user interface of the MDC-700 is accessible from a wide variety of devices anywhere.
  • Page 6  Config.csv to Ease Hard Work of Editing a Lot of Definition Editing and checking a lot of polling definitions is a hard work and it may make mistakes. Users can easy to manage so many definitions in a CSV format file with Excel and import or export the config.csv via a simple mouse-click action.
