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).

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

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.
z

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.

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.

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.
