The connecting procedure varies with the mounting type of the sensor amplifiers to be connected. 2 NOTICE Connection and Configuration Point Make sure that the sensor amplifiers are turned off before connecting the EtherNet/IP Compatible Network Unit DL-EP1.
2-2 Installation and Connection to Sensor Amplifiers 3 Mount the supplied end units (OP-26751: a set of two pieces) on the outer ends of the amplifier and the EtherNet/IP Compatible Network Unit DLEP1. Then, fix the end units with the screws on the top of each end unit (2 points x 2 units). (Tightening torque : 0.6 Nm or less) Mount the end units in the same way as the EtherNet/IP Compatible Network Unit DL-EP1.
2-3 Wiring The DL-EP1 uses the power supplied to sensor amplifiers, so there is no power cable wiring. This section describes the wiring of communication cables used by the DLEP1. 2 Connecting a communication cable Connection and Configuration Use the following procedures to connect the DL-EP1 to the communication cable required for EtherNet/IP communication. Usable cable Usable cables depend on whether the system is configured with 10BASE-T or 100BASE-TX.
2-3 Wiring DL-EP1 connector port The DL-EP1 connector port accepts an RJ-45 8-pole modular connector (ISO8877 compliant) used with 10BASE-T and 100BASE-TX and complies with the IEEE802.3 Standards.

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.

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.

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.

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.
