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