1-1 DL-CL1 Overview

Overview

This unit operates as a remote device station (Ver. 1.1 and 2 switchable) of a CC-Link system. Using CC-Link communications, the sensor amplifiers and other units connected to the DL-CL1 can transmit their ON/OFF control signals and current values as communication data to PLC or other equipment.

The DL-CL1 supports cyclic transfer and extended cyclic transfer, enabling data communication without the need of a ladder program. In addition, remote input/output signals can be used as handshake signals to read/write settings of sensor amplifiers and to execute motion commands on the sensor amplifiers.

The DL-CL1 can connect multiple sensor amplifiers (a single main unit and multiple expansion units) which support D-Bus. "D-bus" is the name of KEYENCE's wiringsaving system for sensor amplifiers.

Different types of sensor amplifiers with D-bus support can be connected to the single DL-CL1 unit.

How many and what different types of sensor amplifiers can be connected depends on the sensor amplifiers or units to be connected. Please inquire for details.

2-1 Installation and Connection to Sensor Amplifiers

This section provides the procedures for installing the DL-CL1 and connecting to sensor amplifiers.

The DL-CL1 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.

ID Number Assignments to Sensor Amplifiers

When connecting the DL-CL1 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 08.

Point • The ID number assignments to sensor amplifiers cannot be changed by the user.

•In this manual, ID number 01 to ID number 08 are denoted as ID 01 to ID 08, respectively.

Procedures for connecting to sensor amplifiers

The CC-Link compatible communication unit DL-CL1 must be connected to sensor amplifiers before it can provide its function.

The connecting procedure varies with the mounting type of the sensor amplifiers to be connected.

Make sure that the power to the sensor amplifier is off before starting to NOTICE connect the CC-Link compatible communication unit DL-CL1. Perform-

ing the procedure with the power on may damage the DL-CL1.

Point For the instructions on connecting additional sensor amplifiers, refer to the instruction manual of the sensors amplifiers.

 Connecting to sensor amplifiers of DIN rail mounting type

1	Remove the expansion protective cover from the sensor amplifier to be
	connected.

This section describes how to wire the DL-CL1.

Point • Turn off the power before starting the cabling operation.

•For more information about the CC-Link system, including cable length and cabling methods, refer to the document of the CC-Link master unit.

Connecting to the CC-Link System

Use the following procedures to connect the DL-CL1 to the CC-Link system.

Usable cables

For connection between the DL-CL1 and the CC-Link system, use CC-Link cables (Ver. 1.10 or later) accredited by the CC-Link Partner Association.

CC-Link cables (for Ver. 1.10) are available as optional items.

OP-79426 (20 m) OP-79427 (100 m)

Point To ensure normal communication, only use the CC-Link cables.

Trimming the cable
