1-1 DL-DN1 Overview

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.

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.

Item		Description
(1) Address setting switch	Sets the DeviceNet node address of the DL-DN1.
	x10	: Ten's digit
	x1	: One's digit

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 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.

2-1 Installation and Connection to Sensor Amplifiers

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

2amplifiers.) 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.

Configuration and Connection

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.

Point • 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.

"I/O Communication" (page 3-4)

•An error results if more sensor amplifiers are connected than the maximum number of connectable amplifiers.

2-3 Configuring the Data Link

Use the following procedure to connect the DL-DN1 to the DeviceNet system.

Point 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.

	Reference	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-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

	Reference	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.
