MGate 5111 industrial Ethernet gateways convert data between the
protocols. All models are protected by a rugged metal housing, are
DIN-rail mountable, and offer built-in serial isolation.
Modbus is one of the most widely used industrial communication
protocols, and EtherNet/IP, PROFINET, and PROFIBUS are commonly
used in factory automation and process automation. The MGate 5111
supports both Modbus RTU/ASCII/TCP master and slave modes, so
that you can easily connect your Modbus device to PROFIBUS PLCs or
DCSs, such as Siemens PLCs.
For Sytem integration, the MGate 5111 can connect to EtherNet/
IP PLC/SCADA systems, such as Rockwell Automation PLCs, to
PROFIBUS PLC/DCS systems, or between a new Siemens PLC system
that supports PROFINET to an existing PROFIBUS system. The
MGate 5111 gateways are designed for easy configuration and quick
maintenance. A handy web console can be used to implement remote
maintenance tasks, and the configuration wizard UI lets you quickly set
up your gateway. A comprehensive collection of troubleshooting tools
reduce configuration time and system downtime. The rugged design
is suitable for industrial applications such as factory automation,
power, oil & gas, water and wastewater, and other process automation
Easy Configuration
The MGate 5111 series gateway has a friendly user interface that lets
you quickly set up protocol conversion routines for most applications,
doing away with what were often time-consuming tasks in which users
had to implement detailed parameter configurations one by one. With
Quick Setup, you can easily access protocol conversion modes and
finish the configuration in a few steps. The MGate 5111 supports a
web console and Telnet console for remote maintenance. Encryption
communication functions, including HTTPS and SSH, are supported
to provide better network security. In addition, system monitoring
functions are provided to record network connections and system log
Variety of Maintenance Functions
The MGate 5111 supports Protocol Diagnose and Traffic Monitor
for easy troubleshooting, especially during the installation stage.
Communication issues caused by incorrect software parameters,
like slave IDs and register addresses, or incorrect command
configurations, can be fished out with Protocol Diagnose and Traffic
Monitor, which let you capture and check data to easily identify root
MGate 5111 gateways also support status monitoring and fault
protection functions. The status monitoring function notifies a PLC/
DCS/SCADA system when a Modbus device gets disconnected or
does not respond, in which case the process PLC/DCS gets the status
of each end device and then issues alarms to notify operators. When
a PROFIBUS cable gets disconnected, the fault protection function
executes actions on end devices identified by a pre-defined value set
by the user.
