Page 6: Introduction Of Features
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). -
Page 7: What The Dx Can Do
Introduction of Features 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 data Read **2 Communication input data Read/write External input channel data Read/write *1 Optional (/M1 and /PM1). -

Use RSLinx, RSLogix500, or RSLogix5000 to make an Explicit message or I/O message, download it to the PLC, and execute it. For information on using the configuration tool and a PLC, see the user's manuals of these products. -
Page 10: Explicit Message
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 On the DX, the data count to be accessed per MSG instruction should be 100 or less. - Page 11 Explicit Message Commands: P LC5 Word Range Read/Write, PLC5 Typed Read/Write, and SLC Typed Read/Write Data to be accessed File number Type Number Data type Data type Data type INT16 INT32 FLOAT Measurement N10:00 L10:00 F10:00 channel N10:01 L10:01 F10:01 • • • • • • • • • •...

For Logix, data can be accessed by a "tag name".

Page 13: Data On The Dx
Explicit Message Data Type For a PLC, you can specify the type of read or write data using a file number or tag name in a command. However, the data type is fixed to INT16 for commands "PLC2 Unprotected Read/Write" and "PLC5 Word Range Read/Write." On the other hand, the data types on the DX are determined as shown in the following section, "Data on the DX". For values to be used when the data type specified for a PLC in a command is different from the type of data on the DX, see "Communication Considerations" (on Page 14). - Page 14 I/O Messages System Configuration on PLC An I/O message is also called an Implicit message. An I/O message is used to transmit pre-specified I/O data at intervals. An I/O message is exchanged via a connection path which is first set in RSLinx and read into RSLogix. A connection path defines the IP address of the DX, communication port of the PLC, and distinction of input/output. A device, once configured in RSLinx, can be downloaded into an RSLogix project. The DX is configured as a "Generic Ethernet Module" in RSLogix. Instance ID Each data on the DX corresponds to the instance ID of an Assembly object. In an I/O message, use an instance ID to code the data on the DX to be accessed.

Page 15: Communication Considerations
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. -
Page 16: On Models With The Profibus-Dp Interface (/Cp1 Option)
On models with the PROFIBUS-DP interface (/CP1 option), the communication input data for C01 to C24 (on the DX1000) or for C01 to C32 (on the DX2000) is reserved for PROFIBUS-DP. Because of this, the following limitations apply to EtherNet/IP communications. -
Page 17: Specifications
Specifications The following table shows the basic specifications of the EtherNet/IP server function of the DX. Specifications Description Implementation Level 2 (Message Server + I/O Server) level **2 Maximum 20 connections (0 sessions) number of connections Ports used 4488/tcp, 4488/udp, 2222/udp Supported EIP/PCCC, EIP/native protocols Messaging Explicit (UCMM, Class 3) + I/O (Class 1) Object Assembly, PCCC, Data Table Authentication File No. 10591 (Sep 4, 2007) A "session," a framework of connection management in the encapsulation protocol layer of EtherNet/IP, provides similar functions as a TCP connection to carry out message communications. -
Page 18: Example Of An Explicit Message Using Rslogix 5000
Example of an Explicit Message Using RSLogix 5000 This is an example of using RSLogix 5000 to configure an Explicit message to be sent to the DX by a PLC supporting the CIP Data Table Read/Write command. This section assumes that the reader is familiar with the operations of RSLogix 5000 and RSLinx and that RSLogix 5000 can communicate with the target DX via RSLinx. Making tags initially will be useful. Go to Controller Organizer (a tree on the left side of the screen) and open Controller Tag to make a tag with Data Type of Message (Name the tag as MSG1). Also, make a tag used to retain data to be written to the DX (Name the tag as DATATransfer and store 10 FLOAT values). Make a bit used to launch a message as WriteMessageBit. Controller Tags Name Data Type DATATransfer REAL[10] MSG Message WriteMessageBit BOOL MSG Instruction Go to the Input/Output tab, then the Ladder Element toolbar to select MSG. The MSG block is inserted as ladder output. - Page 19 Example of Explicit Message Using RSLogix 5000 If the connection path to the DX is configured using RSLinx, the connection path is changed to an automatically named pathname (DXADV of ETHERNET-MODULE DXADV shown in the figure below in this example). If the DX is not configured, the I/O Configuration tree does not show ETHERNET-MODULE DXADV. The connection path in the Communication tab is not replaced, either. I/O Configuration Ethernet ETHERNET-MODULE DXADV Message Launch Logic Lastly, configure the message launch logic. In the example shown in the figure below, the MSG block is launched and writes data to the DX when the WriteMessageBit is On. At the same time, the WriteMessageBit is changed to Off and writing is ended.
