Product Features 

 

Support Modbus RTU Master 

The ZigBee, RS-485, or RS-232 on the MDC-211-ZT can be set as Modbus Master. 

MDC-211-ZT 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 ZigBee, RS-485, RS-232 or Ethernet on the MDC-211-ZT can be set as Modbus Slave, 

so the control host can access multiple Modbus RTU devices via MDC-211-ZT 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-ZT provides a simple, friendly Web interface (UI), users can login the 

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

211

-ZT 

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