DL-DN1 Overview
1
Overview
Before Using
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
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.
How many and what types of sensor amplifiers can be connected depends on the
sensor amplifiers or units to be connected. For details, refer to the user's manual of
your sensor amplifiers and "Connecting with Sensor Amplifiers" (page 5-2) in this
manual.

Setting range: 00 to 63
Default value: 63
When setting the node address of the DL-DN1 from
the DeviceNet master unit, set it in the range of 64 to
99. The DL-DN1 is switched to PGM mode.
Point
When the DL-DN1 is set in the PGM mode
- DeviceNet Compatible Network Unit DL-DN1 User's Manual -
and the power is turned on, the address
of the DL-DN1 is the same as used when
the DL-DN1was started last time.
When the DL-DN1 in the factory default
setting is set to the PGM mode, the node
address of the DL-DN1 is 63. Do not start
multiple DL-DN1 units in factory default
setting in the PGM mode, as that will
result in a network error because of the
duplicate node addresses.

This section provides the procedures for installing the DL-DN1 and connecting to
sensor amplifiers.
The DL-DN1 can be connected with the expansion units of sensor amplifiers which
support D-bus. ("D-bus" is the name of KEYENCE's wiring-saving system for sensor
amplifiers.) How many sensor amplifiers can be connected depends on the sensor
amplifiers or units to be connected. For specific numbers of connections, refer to the
manual of each sensor amplifier.
Installation and Connection to Sensor Amplifiers
ID Number Assignments to Sensor Amplifiers
When connecting the DL-DN1 to a sensor amplifier which can be configured with
expansion units, the main unit will be assigned ID number 01, with the expansion units
assigned ID numbers of 02 to 04.
Point
• The ID number assignments to sensor amplifiers cannot be
changed by the user.
• In this manual, ID number 01 to ID number 04 are denoted as ID 01
to ID 04, respectively.

ID number
• Since ID numbers are assigned automatically, changing the number of sensor amplifiers or their connection sequence may require
modification of the control program. In addition, some units are
restricted in their connection sequence (e.g., a unit that must be
the last connection). These considerations should be taken when
configuring the control program.
• Changing the number of connected sensors may change the memory area reserved in the DL-DN1.
• An error results if more sensor amplifiers are connected than the
maximum number of connectable amplifiers.

Use the following procedure to connect the DL-DN1 to the DeviceNet system.
Configuring the Data Link
This manual covers only the functions and settings of a DeviceNet master
unit which are required for communication with the DL-DN1. For the functions
and settings related to the communication between the DeviceNet master unit
and CPU unit, refer to the manuals shipped with your master unit or CPU unit.
Configuring the Master Unit
The following configurations are required to connect the DL-DN1 to the DeviceNet
master unit.
Slave attribute settings
Configure the master unit with the communication form, I/O size, and other
information about the slave units. For this purpose, the EDS file for the DL-DN1 can
be imported into the configuration software of the master unit.
The EDS file can be downloaded from the KEYENCE web site:
http://www.keyence.com
Memory allocation settings
Configure the memory areas required for exchanging data through I/O
communication. Do this using the configuration software of the master unit.
Point
• The memory allocations must be reconfigured if the number of
connected sensors is changed, because the memory area
reserved in the DL-DN1 may change.
• Cautions for connecting the Keyence master unit KV-DN20
Assign the memory allocation start address either to odd-numbered addresses or to even-numbered addresses according to
operating modes of the DL-DN1 (refer to page 2-11). The current
value may not be read out correctly if the assignment is not proper.
Assign to odd-numbered addresses:
3-output + current value (no extended) mode
5-output + current value (no extended) mode
Assign to even-numbered addresses:
Operating modes other than the above
Where multiple slave units are connected, the memory allocation for each
slave unit is done automatically, based on the specified starting address.
The allocation information for each slave unit can be checked using DeviceNet configuration software.
