2-4 Configuring Communication with the DL-EP1 This section describes settings for connecting the DL-EP1 to the EtherNet/IP system. DL-EP1 Settings 2 The following describes how to set communication with the DL-EP1. Connection and Configuration Setting the IP address Set the IP address with the DL-EP1 wired and with the power supplied. By default, the IP address is not set. However, you can use the BOOTP client function to set the IP address via Ethernet.
2-4 Configuring Communication with the DL-EP1 Point Select the device for which to set the IP address and click [Setup IP addr.(I)] to display [Setup IP addr.]. Compare the MAC address to be displayed with the front MAC address on the DL-EP1 and select the device for which to set the IP address. Set an IP address which is not currently used in "IP addr.(required)(I)" and click the [OK] button. Reference Using the [Search available IP addresses (F)] button enables you to search for open IP addresses.
2-4 Configuring Communication with the DL-EP1 3 The IP address has now been set. 2 Connection and Configuration Reference What is BOOTP? BOOTP is the abbreviation of BOOT strap Protocol. This protocol is used by the client device in the TCP/IP network to make the network settings assigned from the server. If there is a BOOTP server in the same network as the device running as the BOOTP client, an IP address is assigned to the device connected as the BOOTP client.
Configuring Communication with the Scanner 2-5 This section describes scanner side configuration for connecting the DL-EP1 to the EtherNet/IP system. When communicating with an Allen-Bradley scanner, also refer to the "Procedures for Communicating with an Allen-Bradley ControlLogix PLC" (Page 5-6). 2 Setting the scanner Setting the IP address Set the IP address of the scanner.

The specifications are managed by ODVA (Open DeviceNet Vendor Association, Inc.). Industrial protocol has been combined with the Ethernet and standardized as EtherNet/IP (Industrial Protocol). Communication is realized by combining the protocols known as Common Industrial Protocol (CIP) with TCP/IP and Ethernet. This allows regular Ethernet to be used together with the network.

Message Communication 3-4 This section describes the message communication functions and how to use them. What is Message communication (Explicit messaging)? Message communication is a function that performs communication by issuing commands using the objects and services (Service Codes) prepared for each EtherNet/IP device. Message communication is used for applications which do not require the punctuality of cyclic communication, such as reading and writing adaptor settings.

3-4 Message Communication Reference 3 ・ In EtherNet/IP (CIP), the method called "object modeling" is used to express a device. The device is handled as a group of objects. Objects abstractly express the configuration elements in the device. A class is a group of objects expressing the configuration elements of the same type. An instance actually expresses a specific object contained in a class. Each instance in the class has the same attribute group, but each uses a unique attribute value.

Appendix 4 Download the settings to the PLC.
5-4 Procedures for Communicating with an Allen-Bradley ControlLogix PLC Point To carry out cyclic communication with multiple PLCs using the InputOnly connection, the DL-EP1 input data must be sent as a Multicast packet. With ControlLogix, the DL-EP1 transmission is fixed to Multicast packet. However, caution is required when using devices, such as KV or SYSMAC, for which the connection method can be selected from Multicast or Point to Point.
