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

*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.

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.

Communication Considerations
About Communication Interval
Data Update
The DX data is updated in a scan interval. Even if a PLC accesses the data at shorter
intervals than the DX scan intervals, the data is updated only at scan intervals.
Communication Interval
A PLC should access the DX at intervals of 125 ms or longer.
* This is required to maintain compatibility with other protocols supported by the DX than
EtherNet/IP.
Access to Non-existent Data
If non-existent data is accessed, either of the following operations occur.
• 0 is read if non-existent data is read.
• Nothing is done if non-existent data is written.
When the DX Data Type Differs from the Data Type Specified in a Command
Each data on the DX has a fixed data type.
Data on the DX which includes special data accessed using the same data type is
transmitted unchanged. Data on the DX accessed using a different data has its data type
converted. The following explains the conversion rules:
