Assigning ID Numbers

Several sensor amplifiers can be connected to the DL-EP1. ID numbers for data identification are assigned to each sensor amplifier.

The method for assigning ID numbers is as follows:

•ID numbers are assigned in order, starting from the sensor amplifier that is the main unit. (Optional numbers cannot be assigned.)

•0 is assigned as the ID number of the DL-EP1.

Point		• You cannot change the ID numbers assigned to the sensor amplifiers.
		• In this manual, ID number 00 to ID number 08 are denoted as ID00 to
		ID08, respectively.

Also for cyclic communication, output, current value, and external input are assigned one by one per ID number.

2-3 Wiring

2

Configuration and Connection

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.

Connecting a communication cable

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.

Structuring a 10BASE-T system

When the system is configured	STP/UTP cable
with 10BASE-T, use a Category
3 or higher shielded twisted-pair
(STP) cable or an unshielded
twisted-pair (UTP) cable.

Structuring a 100BASE-TX network

When the system (network) is configured with 100BASE-TX, use a Category 5 or higher STP or UTP cable. Do not use a Category 3 or Category 4 UTP cable.

Point		• Use a STP/UTP straight cable when connecting the DL-EP1 to an
		Ethernet switch.
		• Use a STP/UTP cross cable when directly connecting the DL-EP1 to a
		PC.
		• Do not use the STP/UTP cross cable incorrectly because it is difficult to
		distinguish this cable from the STP/UTP straight cable in appearance.
		• When the system (Ethernet) is configured with a type (e.g., 10BASE-2
		or 10BASE-5) other than 10BASE-T and 100BASE-TX, use an Ethernet
		switch with an AUI (MAU) connector or a BNC connector or use a media
		converter (10BASE5 → 10BASE-T or 10BASE2 → 10BASE-T).

2-8	- EtherNet/IP Compatible Network Unit DL-EP1 User’s Manual (IL) -

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.

Precautions for connecting a STP/UTP cable to the DL-EP1 connector port

Take care not to apply a load to the DL-EP1 connector port when connecting the STP/UTP cable to the DL-EP1.

The cable may be bent and used when installed. Bending the cable

at a sharp angle may cut the wires in the cable or the cable may be NOTICE disconnected during use. Install or lay the cable to be used with

attention to the recommended bending radius R of the cable.

Connecting the DL-EP1 to EtherNet/IP

The following describes how to connect the DL-EP1 to the RJ-45 connector.

1	Turn off the power supply.
2	Connect one modular jack of the STP/UTP cable to the 10BASE-T/
	100BASE port of the Ethernet switch to be used.

Insert the modular jack until a "click" is heard. The modular jack and connector will lock.

Point Keep the length of the STP/UTP cable to be used 100 m or less.

Carefully check the state of connector (port) on the Ethernet switch before connecting the DL-EP1. There are various Ethernet switches. Some Ethernet switches have a different shape connector (AUI connector or BNC connector, etc.) from the RJ-45, while some have connectors used to connect Ethernet switches together (cascade ports).

3	Connect the modular jack on the other end of the STP/UTP cable to the
	DL-EP1 connector port.

Insert the jack until a "click" is heard. The modular jack and connector will lock.

	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.

2-5 Configuring Communication with the Scanner

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).

Setting the scanner

Connecting the DL-EP1 to the EtherNet/IP scanner requires the following settings:

Setting the IP address

Set the IP address of the scanner.

Registering the device profile of the DL-EP1

Register the device profile of the adaptor (DL-EP1) to be connected using the scanner's setting software.

You can register the device profile manually or by reading the EDS (Electronic Data Sheet) file. You can download the EDS file of the DL-EP1 from the Keyence web site (http://www.keyence.com).

Configuring communication with the DL-EP1

The DL-EP1 uses EtherNet/IP cyclic communication or message communication to communicate with the scanner.

zCyclic communication (Implicit messaging)

This function sends and receives data at a set RPI (Requested Packet Interval). Selecting the communication method called "connection" and assigning the devices to be sent and received on the scanner side enables the DL-EP1 to communicate with the scanner without creating a ladder program.

zMessage communication (Explicit messaging)

This function is used to send and receive data which does not need to be timed. Use this function when changing the sensor amplifier settings or when performing EtherNet/IP communication with the scanner (e.g., Allen-Bradley SLC5/05 Series) that does not support cyclic communication.

This function uses a ladder program to create a message on the scanner side for communication.

For more information on setting each communication method, refer to the chapters titling "Communicating with...." of each sensor amplifier as well as the manuals enclosed with each scanner.

	Reference	This manual explains only the EtherNet/IP scanner functions and settings
		required for communication with the DL-EP1. For details on the functions
		and settings between the EtherNet/IP scanner and CPU unit, refer to the
		manuals enclosed with the scanner and CPU unit.
