Ethernet Modbus Gateways
Modbus is the standard used for communication between a wide range of industrial devices, including PLCs, DCSs, HMIs, instruments, meters, motors, and drives. Although Modbus can be used for both serial (RS-232, RS-422, and RS-485) devices and newer Ethernet
devices, the serial and Ethernet protocols are so different that a specialized gateway is required for one protocol to communicate with the other. Moxa’s MGate™ products are specially designed to integrate Modbus TCP and Modbus RTU/ASCII networks. MGate™ MB3000 products support one or two Ethernet connections, and up to four serial ports.
The MGate™ line of Modbus gateways includes products that support these advanced features:
- Multiple masters
- Priority control
- Smart routing
- Serial redirector
- Powerful Windows Utility
