Welcome to Moxa NPort 6110 Modbus/TCP to Serial Communication Gateway,

an easy-to-use Ethernet to RS-232/422/485 Modbus Gateway.

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.

Features

❑Integration of Modbus serial and Modbus Ethernet devices

❑Supports connecting a Modbus/TCP Master device to up to 31

Modbus/ASCII/RTU slave devices

❑Supports connecting a Modbus/ASCII/RTU master device to up to 4

Modbus/TCP slave devices

❑Easy-to-use Windows utility for configuration over Ethernet

❑10/100M fast Ethernet with automatic IP setting (DHCP)

❑One software selectable RS-232/485/422 interface

❑High speed serial interface—up to 230.4 Kbps
