<span class='text_page_counter'>(78)</span><div class='page_container' data-page=78>

<b>Modbus Serial Protocol</b>

• 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

</div>
<span class='text_page_counter'>(79)</span><div class='page_container' data-page=79>

<b>Modbus/TCP Protocol</b>

• Introduced in 1997. Now use version 1999.

• Suitable for Modicon Quantum PLC

• Also work with other brand’s HMI

_、

DCS.

E.g. Honeywell HC900

<b>Modbus Gateway</b>

• 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.

</div>
<span class='text_page_counter'>(84)</span><div class='page_container' data-page=84>

<b>NPort 6110 Features</b>

• Modbus serial and Ethernet devices
integration

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

• Support TCP, UDP, IP, ICMP, DHCP,
