1-1 DL-DN1 Overview
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 current values as communication data to a
PLC or other equipment.
The DL-DN1 supports DeviceNet I/O communication (polling) and explicit messaging.
I/O polling enables data communication without the need of a ladder program. Explicit
messaging allows for reading/writing sensor amplifier parameters and issuing motion
commands to the sensor amplifiers.
 System configuration example
 Number of Connectable Sensor Amplifiers
The DL-DN1 can connect to multiple sensor amplifiers (a single main unit and multiple
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 supp
or
t can be connected to a single
DL-DN1 unit.
How many and what types of sensor amplifiers can be connected depends on the
sensor amplifiers or units to be connected. Please inquire for details.
