1. Introduction

This section describes the functions, features, software, and hardware specifications of the

MDC-211-WF Modbus data concentrator.

1.1. Introduction to MDC-211-WF

◆ Functions

MDC-211-WF Modbus data concentrator developed by ICP DAS, with Ethernet, Wi-Fi

Wireless, RS-232 and RS-485 communication interfaces, can link the Modbus RTU devices to

the Ethernet network. MDC-211-WF can read the data of Modbus RTU device according to

the user-defined command table, and integrate the data of different Modbus RTU devices

into the format of the continuous address so that the remote monitor host can connect to

MDC-211-WF from Ethernet to access the data of multiple Modbus RTU devices at once.

Through MDC-211-WF's Modbus data centralized management function, as well as the

Ethernet network convenient link and the communication ability, can quickly establish the

stable remote monitoring system, let the user be able to easily simplify the data acquisition

difficulty, and reduces the Ethernet network traffic load, enhances the system efficiency.

◆ Advantages

The advantages of MDC-211-WF Modbus data concentrator, not only to help users

manage the Modbus RTU devices near the RS-232 and RS-485, even in the distance tough

cabling environment, can through the Wi-Fi wireless communication advantages, easy to link

the Modbus RTU devices.

In particular, in the widely used Supervisory Control and Data Acquisition (SCADA), with

simple settings, MDC-211-WF Modbus data concentrator can link the distributed Modbus

RTU devices to the Ethernet network, which is the best solution for the user to establish the

remote monitoring control system quickly.

ICP DAS, MDC-211-WF user manual , v1.1 Page 4

1.2. Product Features

◆ Support Modbus RTU Master

The Wi-Fi, RS-485, or RS-232 on the MDC-211-WF can be set as Modbus Master. MDC-

211-WF can read the data of the Modbus RTU device according to the user-defined command

table, and integrate the data of different Modbus RTU devices into the format of the

continuous address for centralized management.

◆ Support Modbus TCP/RTU Slave

The Wi-Fi, RS-485, RS-232 or Ethernet on the MDC-211-WF can be set as Modbus Slave,

so the control host can access multiple Modbus RTU devices via MDC-211-WF at once.

By establishing the function of Modbus Master and Modbus Slave, the Modbus data

monitoring control system will be more efficient, stable and flexible to meet the diverse

application sites.

◆ Support Web-based UI Operations

MDC-211-WF provides a simple, friendly Web interface (UI), users can login the MDC-

211-WF Web page via a Web Browser to set up and real-time detect the MDC-211-WF for

the communication status and update frequency of each Modbus RTU command.

ICP DAS, MDC-211-WF user manual , v1.1 Page 5

◆ Support Parameter Setting via CSV File

CSV (Comma-Separated Values) is a text file format that can be edited in spreadsheet

software or plain text files and has the advantage of being easy to use, read and maintain.

MDC-211-WF parameter setting includes the Modbus TCP communication ID and port

number, the Serial port communication parameters and the Modbus RTU commands that

settings can also be edited in a *.csv file and import into the MDC-211-WF from the Web UI,

and then start to monitor the data of the remote Modbus RTU devices.

◆ Support Wi-Fi Communication Protocol

The MDC-211-WF support Wi-Fi standard (IEEE 802.11 a/b/g/n). User can access the data

of Modbus/RTU by Wi-Fi. User can reduce the wire because of wireless communication.

Otherwise, the MDC-211-WF also support 5 GHz. The 5 GHz can avoid the other interferences

from 2.4 GHz.

MDC-211-WF supports two Wi-Fi modes. One is Wi-Fi AP(Limit-AP). The other is AP Client

(Infrastructure) mode. The following figure has shown the application of each mode.

ICP DAS, MDC-211-WF user manual , v1.1 Page 6

1. Limit-AP Mode

The MDC-211-WF is a Modbus/RTU to Modbus/TCP gateway in Limit-AP mode. The

device can connect to MDC-211-WF by Wi-Fi. The device can connect to the WF-2572M

when it didn’t have Wi-Fi function. The device can send Modbus/TCP command to acquire

data from Modbus/RTU device.

2. Infrastructure mode

The MDC-211-WF is a Wi-Fi AP client in the Wi-Fi infrastructure mode. The MDC-211-

WF can connect to other Wi-Fi AP. The SCADA/HMI and control center can connect

together by Ethernet switch. The device can send Modbus/TCP command to acquire data

from Modbus/RTU device.
