Introduction of Features
EtherNet/IP
EtherNet/IP is a protocol that extends Common Industrial Protocol (CIP) to Ethernet.
TheuseofEthernetenableshigh-speedandperiodicexchangeofmassivecontroland
monitoringdatabetweencontroldevicesplacedatdispersedlocations.
DevicesthatsupportEtherNet/IPareavailablefrommany vendors.Among them,
RockwellAutomation's Programmable Logic Controller (PLC) and Remote I/O of the
Allen-Bradley brand are widely used.Yokogawa's DX, equipped with the EtherNet/IP
serverfunction,supportscommunicationswiththesePLCs.
Configuration Components
• Scanner (Client)
 AdevicethatlaunchesarequestonEtherNet/IP.ThisiseitheraPLCorPC.Forthe
DX,PLCssuchasAllen-BradleyPLC-2,PLC-5,SLC500,MicroLogix,CompactLogix,
andControlLogixrepresentaScanner(Client).
• Adapter(Server)
 A remoteI/OdevicethattheScanner(Client) canaccessto readorwrite data.The
DXisanAdapter(Server).
• Configurationtool
 A toolusedtoconfigurethesystem.ThisiseitheraPConwhichconfiguration
software has been installed or the software itself.
 RockwellAutomation RSLogix500 and RSLogix5000 and the communication driver
software RSLinx are configuration tools.

What the DX Can Do
TheDXprovidesthefollowingfunctions:
• ParticipateinanEtherNet/IPnetworkasanAdapter(Server).
• CommunicatewithnewandoldAllen-BradleyPLCssuchasMicroLogix,
CompactLogix,ControlLogix,SLC500,PLC-5,andPLC-2.
• SupportbothExplicitandI/Omessages.
• PLCscanaccessinternaldataoftheDX.
Data Access
Measurement channel data Read
Computationchannel*1 data Read
Communicationinputdata*1*2 Read/write
External input channel data*3 Read/write
*1Optional(/M1and/PM1).
*2Communicationinputdata,ifcodedinacalculationexpressioninthecomputationchannel,
can be displayed on the DX.
*3ThisfunctionisavailableonlyontheDX2000.Optional(/MC1).
The following shows examples of usage.
• DataondevicesonanetworkcanberecordedbyaPLCtotheDX.
• DatameasuredbytheDXcanbeacquiredbyaPLC.
Settings of the DX
TheDXisreadytouseafterthefollowingsettingshavebeenmade.
• IP address and other settings required to connect to Ethernet
• EnablingofEtherNet/IPserverfunction
Access to the DX
TheDXisapassivedeviceonanEthernetnetwork.TheDXcannotlauncharequest.A
PLClaunchesarequesttotheDX.
A request is called a "message". There are two message types: Explicit message and
I/Omessages(Implicitmessage).AnExplicitmessage,includedincontrollogic,isused
to access the DX, only when required, and transmit data.An I/O message is used to
transmitpre-specifiedDXdataatintervals.
TheDXsupportscommunicationswithold-modelAllen-BradleyPLCsnotcompatiblewith
EtherNet/IP. The DX can also communicate with PLCs compatible with Programmable
Controller Communication Command (PCCC) using conversion of PCCC to EtherNet/
IP atthegateway.PCCCreferstoserialcommunicationsthatarealsocalledDF1
communications.
TheDXsupportsEtherNet/IPinwhichPCCCrequestsareencapsulated.Itcan
communicatealsowithPLCsthatsupportencapsulatedPCCC.

Connection to a Network
Cable Connection
ConnecttheEthernetcabletotheEthernetportprovidedonthebackoftheDX.
Ethernet cable
CAUTION
Be sure to connect an Ethernet cable
with an FCC-compliant plug. Otherwise,
the MV may malfunction.
Settings of the DX
IP Address, Host Information, and DNS Setting, etc.
See Section 1.3 of the Communication Interface User's Manual (IM04L41B01-17E).
EtherNet/IP Server Settings
Press MENU (to switch to setting mode), hold down FUNC for 3 s (to switch to basic
setting mode), and select the Menu tab > Communication (Ethernet) > Server >
Server modes.
• Server
Set EtherNet/IP to Use.
Note
TheEtherNet/IPserversettingscanbecheckedontheNetworkInformationScreenoftheDX.
YoucanopentheNetworkInformationScreenbypressingtheFUNC > Network info soft key.

Installation
TohavetheDXparticipateinanetwork,firstinstalltheDXdeviceprofile(ElectronicData
Sheet;EDSfile)intheconfigurationtool.APLCcommunicateswiththeDXbasedonthe
information in the EDS file.
Conductinstallationusingthe"EDSHardwareInstallationTool"ofRSLinx.For
information on using the configuration tool, see the user's manual of the configuration
tool.

Explicit Message
AnExplicit message is a point-to-point, request/response-type communication.
System Configuration on PLC
Use the configuration tool to code an Explicit message as an MSG instruction in the
control logic. In the MSG instruction, set all the information including a target device,
targetregister,andread/write.DownloadthecreatedcontrollogictoaPLCandexecute
it.
OntheDX,thedatacounttobeaccessedperMSGinstructionshouldbe100orless.
In Case of PLC-2, PLC-5, and SLC
• Commands
 WhencreatinganMSGinstruction,specifyacommand.TheDXsupportsthefollowing
commands:
Target PLC Command name
PLC-2 PLC2UnprotectedRead/Write
PLC-5 PLC5WordRangeRead/Write
PLC5TypedRead/Write
SLC SLCTypedRead/Write
• Specification of data to be accessed
 SpecifywhichofthedataintheDXshouldbeaccessed.ThePLC-2,PLC-5,andSLC
manage data to be accessed in units of "files."
For an external input channel, separate access destinations are used for reading and
