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.
