Overview
The MGate MB3000 is a line of protocol gateways that provides users with
y seamless integration of Ethernet and serial Modbus devices
y powerful operation modes to handle almost any Modbus application
y Windows utilities for easy setup and traffic monitoring
Seamless integration of Ethernet and serial Modbus devices
Modbus is one of the most popular automation protocols in the world, supporting traditional
RS-232/422/485 devices and recently developed Ethernet devices. Many industrial devices, such
as PLCs, DCSs, HMIs, instruments, and meters, use Modbus as their communication standard.
However, the Ethernet-based Modbus protocol is so different from the original serial-based
protocols that a communication gateway is needed as a bridge for integration.
In order to integrate Modbus networks, the MGate MB3000 includes an Ethernet port and up to
four serial ports that support RS-232, RS-422, and RS-485 communication. It automatically and
intelligently translates between Modbus TCP (Ethernet) and Modbus ASCII/RTU (serial)
protocols, allowing Ethernet-based PLCs to control instruments over RS-485 without additional
programming or effort.
Powerful operation modes to handle almost any Modbus application
With the Modbus protocol, devices must be clearly defined as either masters or slaves. Unlike
other Modbus gateways, the MGate MB3000’s operation modes allow users to select master or
slave operation for each serial port. Not only does the MB3000 allow Ethernet masters to control
serial slaves, it also allows serial masters to control Ethernet slaves. On multiport models, each
serial port’s operation mode is independent of the other ports, so that one port may be configured
for slave mode and another port configured for master mode.
Extra address mapping and exception parameters are provided to ensure that most situations can be
handled.
Windows utilities for easy setup and traffic monitoring
A Windows utility is provided to make configuration and operation of the MGate MB3000 as easy
as possible. The utility automatically connects to all available MGate MB3000 units on the LAN
for you. Traffic monitoring functions help you troubleshoot Modbus communication problems by
tracking items such as connection status and address translation errors.
