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.

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.
