Connection and Configuration
- DeviceNet Compatible Network Unit DL-DN1 User's Manual -
2-3 Configuring the Data Link
Use the following procedure to connect the DL-DN1 to the DeviceNet system.
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.
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.
• 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-num-
bered 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 Devi-
ceNet configuration software.
