Typical Applications

Ethernet Masters with Multiple Serial Slaves

Connect all Modbus devices over an Ethernet network

Most modern PLCs and host computers support Modbus TCP over Ethernet. In order to access discrete
Modbus RTU/ASCII devices for data collection and control, they can rely on the MGate MB3000 Modbus
gateway.

The MGate MB3000 supports Modbus TCP with up to 16 or 32 simultaneous connections. The serial interface
supports both RS-232 and RS-422/485, selectable through software. Each serial port can be connected to
one RS-232 or RS-422 serial device, or to 31 RS-485 serial devices.

Serial Masters with Multiple Ethernet Slaves

Link a serial master device with Ethernet slave devices

Many HMI (Human Machine Interface) systems use a serial interface to connect to a discrete DCS (Data
Control System). However, many DCSs are now Ethernet-based and operate as a Modbus TCP server
device.

The MGate MB3000 Modbus gateway can link a serial-based HMI to distributed DCSs over an Ethernet
network. Up to 32 Modbus TCP server devices are supported by each MGate MB3000.
