* MGate MB3170/3270 Modbus gateway has received Taiwan Excellence and Good Design awards.
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 Ethernet masters. A
special priority control feature allows urgent commands to obtain
immediate response. All models are ruggedly constructed, are DIN-rail
mountable, and offer built-in optical isolation for serial signals as an
option.
Integration of TCP masters without alteration to Modbus RTU/ASCII network or software
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 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.
Cascading Ethernet ports for easy wiring
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.
Redundant power inputs
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.
Warning by relay output
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.
Priority control for urgent commands (Patented)
As Modbus networks increase in size and complexity, the lag time
between commands and responses becomes a major concern. Advanced models
of the MB3000 series provide a priority control function for urgent
commands, allowing users to force certain commands to get an immediate
response. Depending on your system’s requirements, different methods are
available to define which commands receive priority.
