Outline
The DL-EP1 is an EtherNet/IP compatible adaptor which can read and write the data from the
connected sensor amplifier from a PLC (programmable controller) or PC (personal computer).
• The DL-EP1 supports cyclic communication. Data can be exchanged without a ladder program.
• The DL-EP1 also supports UCMM and Class 3 (explicit message communication). The sensor amplifier settings and status can be read and written at a random timing, and motion commands can be issued to the sensor amplifier.
Types and Number of Connectable Sensor Amplifi
The DL-EP1 can connect a maximum of 15 sensor amplifiers (main units and expansion units)
which support D-bus. ("D-bus" is the name of KEYENCE's wiring-saving system for sensor
amplifiers.)
Different types of sensor amplifiers with D-bus support can be connected to a single DL-EP1
unit.
The number of connectable units, and a mixed environment of different models, depend on the
particular sensor amplifiers or units. Refer to the “DL-EP1 User’s Manual”.
Checking the Package Contents
Before using the DL-EP1, make sure that the following equipment and accessories are included
in the package.
We have thoroughly inspected the package contents before shipment. However, in the event of

How to connect to the sensor amplifier
The EtherNet/IP Compatible Network Unit DL-EP1 is used by connecting it to a sensor amplifier.
The connection method varies according to the mounting type of the sensor amplifier to connect
to.
When connecting the EtherNet/IP Compatible Network Unit DL-EP1, be
sure to check the power of sensor amplifier is OFF before performing the
operation. Performing the operation when the power of sensor amplifier
is ON may damage the equipment.
Refer to the Instruction Manual of each sensor amplifier for details
