Page 5: Product Introduction
1.1. Introduction  Functions The MDC-211-433 is a Modbus data concentrator developed by ICP DAS. It features Ethernet, 433MHz wireless communication, RS-232, and RS-485 communication interfaces, and can connect Modbus RTU devices to the Ethernet network. The MDC-211-433 sequentially reads data from Modbus RTU devices according to a user-defined command list and integrates the data from different Modbus RTU devices into a continuous address format.
Page 6  Advantages The MDC-211-433 Modbus Data Concentrator not only helps users manage local RS- 232/RS-485 Modbus RTU devices but also easily connects to remote and dispersed Modbus RTU devices through the 433MHz wireless network, even in environments where wiring is difficult.
Page 7: Features
The MDC-211-433 offers a simple and user-friendly web interface. Users can configure the MDC-211-433 using a computer with internet access via a web browser. It also allows real-time monitoring to check for abnormalities in the connections of each Modbus RTU command and their update frequencies.
Page 8 Modbus RTU command settings, can also be configured in a *.csv file. By importing this file through the web interface, users can begin monitoring data from remote Modbus RTU devices.  ICP DAS, MDC-211-433 User Manual Version 1.0 Page 8 Copyright © 2024 ICP DAS Co., Ltd.
