1. Introduction
Modbusisan industryadopted communication protocol based on RTU, ASCII, and TCPprotocols for
various applications; these three protocols are commonlyused byhardware equipments in the industry,
such asDCS, PLC, HMI,powerload measurement,varioussensorand measuring instruments.The
ModbusGatewayis capableof implementingthe Modbus environment between different hardware
interfaces,therebystreamlining the process of management and application.
Diverse Hardware Infrastructure
Modbus Gatewaysupportsthe four most commonlyused hardware communication interfaces, RS232,
RS485, RS422, and Ethernet. The simple-to-use configuration software provided with ModbusGateway
can quicklymodifythe hardware interfaceto use, and easilyswitchto the existing hardware
communication infrastructure.
Switching between Modbus Protocols
ModbusGatewaysupportsthe standard Modbusprotocol and is capable of convertinganyModbus
protocolsbetween ModbusTCPand Modbus RTU orModbus ASCII for all supported hardware
interfaces.

TCPConnections(s): Maximum of four simultaneousModbus/TCPconnections is allowed.
Serial Reply Timeout:Ifthe serial side does not respond withthe specified time, datawouldbe dropped
and not transmitted overTCPeven if the gatewayreceivesit later.
Serial Protocol:Select between Modbus/ASCII and Modbus/RTU.
Please note that Serial interface onlysupport ModbusMaster.
Serial Timeout Retry:If “0”isset, the gatewaywould not store TCPpacketsin the buffer.If thenumber is
greater than “0”,the gatewaywould storethe TCPpacketsin the buffer and retries the specified timeswhen
the Modbusdevice on the serial sidedoesnot respond.

note that the setting willnot become effective until “restart”isclicked.
3.4 Assign a NewIPAddressby ARPCommand
Use ARPcommand to assign astaticIP addressofATC-3001 using its hardwareMAC address.The MAC
address is printed on the rear side of device in the format of "0060E9-xxxxxx". The following example shows
howit workswithin MS-DOS command prompt window.
(Forexample change IPfrom 10.0.50.100 to 10.0.50.101,and theMACaddressof ATC-3001 is
00-60-e9-11-11-01)
Step1: Add the new hostIPto ARPtable
->Open Ms-DOScommand prompt window
->Input arp -s 10.0.50.101 00-60-E9-11-11-01 (Figure3.20)
Figure 3.20. Ms-DOS command prompt window
Step2: Change to new IPvia telnet port 1 (Figure 3.21)
->Input telnet 10.0.50.101 1
Note: The telnet will be fail and ATC-3001 will be restarted automatically,after restart the IPaddress
should be change to 10.0.50.101
Step3: Using newIPto configure ATC-3001 via telnet
->Input telnet 10.0.50.101
Note 1: When using this method to change IPaddress, PC'sIP addressandATC-3001'sIPaddress
must belong to the same subnet.
Note 2: The changed IPaddressmustbe legal, otherwise it will be changed backto the default value
(10.0.50.100) afterrestart.

4.1 SNMPNetwork Management Platform
ATC-3001 isan SNMPdevicethat allowsmanypopular SNMPNetwork management platformssuch asHP
Open View.
Dependingon thenetworkmanagementtools one areusing,deviceATC-3001 information can be collected
from running the managementtoolsincluding IPaddress, DNS name, system descriptions and NIC
information etc.
4.2 UsingNetworkViewas an Example
NetworkViewis acompact networkmanagement toolfrom NetworkView Software, Inc.
(www.networkview.com). It discoversall TCP/IPnodes in anetwork using DNS, SNMPand portsinformation
and documents with printedmapsand reports for future use.
First, download and install the tool on ones PC (Windows 2000 and Windows XP), then start NetworkView.
1. Clickon the button toopen anewfile. The following screen shall appear,in the Addresses
field, Enter inthe IPaddress range to search (Figure4.1).
