Overview
Moxa NPort 6110 Modbus/TCP to Serial Communication Gateway provides
users with many excellent benefits, including:
!Seamless integration of Ethernet and serial Modbus devices
!Powerful operation modes for versatile Modbus applications
!Windows utility for easy setup and traffic monitoring
Each of these benefits is explained in more detail below.
Seamless integration of Ethernet and serial Modbus devices
Modbus is one of the most popular automation protocols in the world. Modbus
protocol supports traditional RS-232/422/485 devices and newly developed
Ethernet devices. Many industrial devices, such as PLCs, DCSs, HMIs,
instruments, and meters, use Modbus as their communication standard. However,
the Modbus protocols that run over serial and Ethernet are so different that a
communication gateway is needed as a bridge for integration.
NPort 6110 supports one Ethernet and one software selectable RS-232/422/485

1-2
port that can connect to many types of Modbus device. By translating
Modbus/TCP (Ethernet) and Modbus/ASCII/RTU (Serial) protocols, a PLC with
Ethernet can use the RS-232/485 interface to seamlessly communicate with
instruments.
Powerful operation modes for versatile Modbus applications
For Modbus protocol conversions, it is necessary to define a Master and Slave
device, but unlike other Modbus Gateways, NPort 6110 allows users to configure
Master/Slave for both the Ethernet and serial sides.
Extra address mapping and exception parameters are provided to ensure that
most situations can be handled.
Windows utility for easy setup and traffic monitoring
NPort 6110 is powerful yet very easy to use. An intuitive Windows utility
automatically searches for all available NPort 6110 units on the LAN.
Traffic Monitoring within the utility helps you troubleshoot any Modbus
communication problem, such as connection status check, or address translation
error check.
