MDC-711
Modbus Data Concentrator with 1 Ethernet, 1 RS-232, 1 RS-485 Modbus RTU Protocol. Shared memory capable. 1-/100 Base-TX, 8 Max connections. Has operating temperature range of -25°C ~ +75°C (-13°F ~ +167°F)
Features

The MDC-711 device is a Modbus Data Concentrator that is capable of performing from up to 200 Modbus RTU commands to read/write from/to Modbus slave devices via RS-232 / RS-485 and it allows up to 8 Modbus TCP masters to get the polled data via the Ethernet.
MDC-711 devices has a built-in web server for quick and easy configuring and viewing of information for the performed results of each Modbus RTU command on the RS-232 / RS-485.
Modbus Data Concentrator
The MDC performs the pre-defined Modbus RTU commands to read/write data from-to the Modbus RTU slave devices via the RS-232 / RS-485. It mirrors the data of the slave devices to its own shared memory. And it accepts up to 8 Modbus TCP masters to directly read/write data form/to the shared memory instead of polling each Modbus RTU slave device one by one. This way not only makes the data on the RS-232 / RS-485 sharable to multiple Modbus TCP master but also shorten the time to read/write data from-to multiple Modbus RTU slave devices.
