MDC-711/MDC-714/MDC-741
Modbus Data Concentrator
 
~ NEW ~    
Model: MDC-711 Model: MDC-714 Model: MDC-741
 
  • Web-based user interface
  • Easy configuration with .CSV file
  • Supports the Modbus RTU master and slave
  • Support for up to 8 Modbus TCP masters
  • Data pool for up to 9600 registers
  • Modbus polling commands for up to 240 definitions
  • Upgrade Modbus/RTU devices with Ethernet communication ability
  • Speed up the time for reading from multiple Modbus/RTU devices
 
MDC-700 series is a Modbus Data Concentrator used to access data from disparate Modbus slave devices with a contiguous Modbus address table ranged by the concentrator. Up to 240 Modbus/RTU commands can be performed to read data from Modbus slave devices via RS-232/485, and up to 8 Modbus/TCP masters are allowed to get the polled data via the Ethernet. The Modbus/TCP masters directly read/write the data in the MDC-700 instead of polling each Modbus/RTU slave device one by one. This way not only makes the data on the RS-232/485 sharable to multiple Modbus/TCP master but also shorten the time to read/write data from/to multiple Modbus/RTU slave devices.

Editing the Modbus/RTU commands for accessing the Modbus RTU slaves is simple and convenient with Comma Separated Values (CSV) format. In addition, a web-based user interface is provided to configure the concentrator and remotely monitor the state of the connection of Modbus RTU slaves.
 
Great Capability of Shared Memory
The MDC-700 module can perform up to 240 polling definitions. And the internal shared memory has four tables to store the polled AI, AO, DI and DO data. Each table can store up to 9600 registers.
Config.CSV to Ease Hard Work of Editing a lot of Definition    
The Modbus polling definition is defined in a Config.CSV file. Editing/checking a lot of polling definitions is a hard work and may have chance to make a mistake. A CSV format file can ease the work by using Excel. Furthermore, a built-in web server allows users import/export the Config.CSV via a simple mouse-click action.
 
     
Web-based Interface for Operating and Displaying Necessary Information    
Users can easy to configure the concentrator and monitor the connection status through the user's regular web browser. They can also edit the polling definition Config.CSV file and import/export the Config.CSV via the web browser interface.
