Usable cable
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.
Use the following procedures to connect the DL-EP1 to the communication cable
required for EtherNet/IP communication.
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
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.
2-6
• 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).

at a sharp angle may cut the wires in the cable or the cable may be
disconnected during use. Install or lay the cable to be used with
attention to the recommended bending radius R of the cable.
Turn off the power supply.
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.
2
Connection and Configuration
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).
Connect the modular jack on the other end of the STP/UTP cable to the
3
DL-EP1 connector port.
Insert the jack until a "click" is heard. The modular jack and connector will lock.

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.

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).
Configuring Communication with the Scanner
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.
Cyclic 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.
Message 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.

What is EtherNet/IP?
What is EtherNet/IP?
EtherNet/IP is an industrial communication network with open specifications. 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.
Communicating with the SK-1000 Series
Before starting EtherNet/IP communication, one of the devices must open a
communication line called a "connection" with the other device. The side which
opens the connection is called the "scanner", and the side to be opened is called the
"adaptor". (The DL-EP1 is an adaptor.)
EtherNet/IP includes cyclic communication (Implicit messaging) which sends and
receives data periodically. Message communication (Explicit messaging) which
sends and receives commands and responses at a random timing.
Cyclic communication enables you to set RPI (Requested Packet Interval) according
to the priority of the data to be exchanged, allowing the entire communication load to
be adjusted for data exchange.
Message communication enables you to exchange the required commands and
responses at the required timing. Message communication is used for applications
which do not require the punctuality of cyclic communication, such as reading and
writing adaptor settings.
