Outline
The DL-DN1 operates as a slave unit of DeviceNet communication. Using DeviceNet
communications, the sensor amplifiers and other units connected to the DL-DN1 can transmit
their ON/OFF control signals and measured values as communication data to PLC or other
equipment.
The DL-DN1 supports I/O communication (poll) and Explicit Messaging. I/O communication
enables data communication without the need of a ladder program. Explicit Messaging allows
for reading/writing sensor amplifier parameters and to issue commands to the sensor
amplifiers.
Types and Number of Connectable Sensor Amplifiers
The DL-DN1 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-DN1
unit
The number of connectable units, and a mixed environment of different models, depend on the
particular sensor amplifiers or units. Refer to the users manual or the instruction manual of your
units.
Checking the Package Contents
Before using the DL-DN1, 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
