MGate™ MB3170/3270
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.
› Conguration is exceptionally easy
› Slave mode supports 16 TCP masters and up to 31 or 62 serial
slaves at the same time
› Master mode supports 32 TCP slaves at the same time
› Emergency request tunnels ensure QoS control
› Serial redirector function provided
› Embedded Modbus protocol analyzer
› Redundant dual DC power inputs
› Built-in Ethernet cascading for easy wiring
A relay output is provided for the Ethernet link and power input status.
The relay output gives maintenance engineers an additional tool for
troubleshooting and maintenance.
