• NPort Modbus Gateway • Typical Applications

Brief History of Modbus

• Modbus is the PLS’s communication

protocol invented by Modicon PLC in 1979. • Modicon PLC was acquired by Schneider

Group.

Types of Modbus Protocol

Protocol Comm. Interface

Introduced time

Modbus RTU RS232,422,485 1979 Modbus ASCII RS232,422,485 1979

Modbus Serial Protocol

• Master/Slave; Half-Duplex; Query and Response.

• Master actively send Query Command, Slave then Response Message

• PLC Control Device : I/O Device as Slave, Monitoring system as Master

Modbus/TCP Protocol

• Introduced in 1997 Now use version 1999. • Suitable for Modicon Quantum PLC

• Also work with other brand’s HMI 、 DCS E.g Honeywell HC900

Let traditional Modbus serial devices talk over Internet

• Modbus serial master device talks to

Modbus serial slave devices over TCP/IP

Connect New Ethernet Modbus device with serial Modbus devices

Modbus Gateway

• Modbus has been widely used in industrial automation fields

• Modbus gateway converts Modbus/TCP (Ethernet) and Modbus/ASCII/RTU(Serial)

interface so that these Ethernet and serial devices communicates

transparently over Ethernet

NPort 6110 Features

• Modbus serial and Ethernet devices integration

• Support Modbus/TCP, Modbus/ASCII, Modbus/RTU

• Support TCP, UDP, IP, ICMP, DHCP, Bootp

• Easy to use Windows utility for configuration over Ethernet

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

Easy-to-use utility
