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, allow
DIN-rail mounting, and offer built-in serial optical isolation 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 have simultaneous access to
serial slaves.
Cascading
Ethernet ports for easy wiring
Advanced
models of the MGate MB3000 provide two Ethernet ports for easier
network wiring. 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
MB3000 advanced models include 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 the demanding requirements of
industrial applications.
Warning by
relay output
Relay
output is provided for Ethernet link and power input status. With relay
output, maintenance engineers have an additional tool for better
troubleshooting and maintenance.
Priority
control for urgent commands (patent pending)
As
Modbus networks increase in size and complexity, the lag time between
commands and responses becomes a growing concern. MB3000 advanced
models provide a priority control function for urgent commands,
allowing users to force certain commands to obtain an immediate
response. Different methods are available to define which commands
receive priority, depending on your system's requirements.
