1 and 2-port advanced serial-to-Ethernet Modbus gateways
The MB3170 and MB3270 are advanced Modbus gateways that 
provide maximum flexibility for integrating industrial Modbus networks 
of all types and sizes. They are designed to integrate Modbus TCP, 
ASCII, and RTU devices in almost any master and slave combination, 
including serial master to serial slave, or simultaneous serial and 
The MB3270 can integrate Modbus TCP with Modbus RTU/ASCII, 
without modifying the existing Modbus RTU/ASCII architecture or 
software. With the serial redirector function, a serial master can 
Ethernet masters. A special priority control feature allows urgent 
commands to obtain an immediate response. All models are ruggedly 
constructed, are DIN-rail mountable, and offer built-in optical isolation 
for serial signals as an option.
maintain direct access to serial slave devices through a specially 
mapped serial port. This allows the serial and TCP masters to access 
serial slaves simultaneously.
Advanced models of the MGate™ MB3000 series have two Ethernet 
ports to make network wiring easier. Dual Ethernet ports allow users 
to string multiple Modbus gateways together using standard RJ45 
Ethernet cables, eliminating the need for a separate Ethernet switch.
Advanced models of the MB3000 series have dual power inputs for 
greater reliability. The power inputs allow simultaneous connections to 
two live DC power sources, so that continuous operation is provided 
even if one power source fails. The higher level of reliability makes 
these advanced Modbus gateways ideal for demanding industrial 
applications.
