Overview

Before Using

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 transfe r, enabli

cation without the need of a ladder program. In addition, remote input/output sig-

muni
nals can be used as handshake signals to read/write settings of sensor amplifiers and
to execute motion commands on the sensor amplifiers.

Configuring the Master Station

To connect the DL-CL1 to the CC-Link master unit, it is necessary to configure the
slave attribute and memory allocation settings.

 Slave attribute settings

Register the DL-CL1 to the CC-Link master unit as a remote device station.
Yo u can also configure the settings by importing a CSP file into the software for the
master unit (ladder programming software or CC-Link configuration software).

Configuring the Data Link

This manual covers only the functions and settings of a CC-Link mas-
ter station which are required for communication with the DL-CL1. For

CC-Link Communication and Operating Modes

The DL-CL1 operates as a remote device station of a CC-Link system.
This section describes the data that the DL-CL1 can exchange through the CC-Link,
and available operating modes.

Data Exchanged by Cyclic Transfer

The DL-CL1's data is linked with the CC-Link maser station as shown below.

Read/write parameters

Through the link, the CC-Link master station is enabled to:

• Communicate the output signal, current value, an

d error status of sensor amplifiers

without the need of a ladder program.

• Use the remote input RX and remote output RY areas as handshake signals to
execute external inputs to, or change the setting values of, sensor amplifiers.

• Execute motion commands on sensor amplifiers.

• Directly read and write the parameters of sensor amplifiers. This capability gives
the ability to use functions that can be executed on sensor amplifiers.

3-1 CC-Link Communication and Operating Modes

Selecting an Operating Mode of the DL-CL1

Select an operating mode of the DL-CL1 to suit the functions of the sensor amplifiers
to be used.
The specific CC-Link device configuration and the data that can be communicated
using cyclic transfer vary with each operating mode of the DL-CL1. An appropriate
operating mode should be determined by considering the number of link points the
data that can be communicated.

amplifiers to be used, before accessing each device.

Device Maps for Small-Memory Mode 1, Small-Memory Mode 2, and Monitor Mode 1

The following device maps are used for when the operating mode is small-memory
mode 1, small-memory mode 2, or monitor mode 1.

This example illustrates how to enter a flow rate hold reset input into the sensor amplifier of ID01.
(1) The value of the remote output device which is assigned an external input request is linked by cyclic

transfer, so that the external input of the sensor amplifier is turned on or off.

(2) The input status of the sensor amplifier can be checked with the external input response (except for

small-

Reading Current Values (Instantaneous Flow Rate) from Sensor Amplifiers

Current values can b e read in the monitor modes and full modes. They cannot be
read in small-memory modes. Instantaneous flow rate is read as the current value
regardless of the detection mode setting.

 Monitor mode 1

When reading current values in monitor mode 1, specify the ID numbers (in terms of
current value page numbers) of the sensor amplifiers to be read to current value
boxes 1 to 3. For details of the current value box numbers and current value page

Communicating with the FD-S series

numbers used for specifying ID numbers, see "Device Maps" (page 3-4).

When reading current values in monitor mode 2 or full mode, see "Monitor mode
2/full mode" (page 3-19).

3-18

This example illustrates how to read the current values from the sensor amplifiers of ID 01/02/03 and ID
07/08/09.
(1) Specify the page numbers in "select current value box page number" and execute "request to change

current value page".

(2) After the current values of the specified current value pages are read, the "current value page

(3) The "current value page change error" signal flips from 0 to 1 if an error occurs during the current

value change process. Check the values specified in the "select current value box page number"
parameter.

3-3 Communication Methods

(5) The current values of the sensor amplifiers of the specified ID numbers are entered into current value

boxes 1 to 3.
If the current value is over range, under range, or invalid, the previous value is retained without
updating the current value. Use the value with the judgment value property.

(6) When the "request to change current value page" command is

set to 0, the "current value page
change complete" parameter flips to 0. If a current value page change error occurred, it is cleared
(0).

(7) Once the current values of the sensor amplifiers are updated, the current value boxes are updated by

cyclic transfer.

 Monitor mode 2/full mode

When reading current values in monitor mode 2 or full mode, read the remote
registers assigned to the ID numbers of the sensor amplifiers. For details of remote

registers, see "Device Maps" (page 3-4).

This example illustrates how to read the current values from the sensor amplifiers of ID 01, 02, and 03.
(1) When the current value of a sensor amplifier is updated, the new comparator value is entered into

remote register RWr.
If the current value is over range, under range, or invalid, the previous value is retained without
updating the current value. Use the value w

Issuing a Motion Command to a Sensor Amplifier

Available motion commands: See "Motion command parameters" (page 3-25).

Commands can be used to reset preset values, clear errors, or for other purposes.
To i ssue a motion command to a sensor amplifier, create a program that controls
commands by handshaking between a remote input/output and remote register

Communicating with the FD-S series

This example executes integration reset on ID 01.
(1) To see that the sensor amplifier is ready to send/receive commands, check that the "sensor ready"

parameter is set to 1.

*1 The error content of the sensor amplifier can be checked by noting the ON/OFF

state of each bit.
OFF (0): No error; ON (1): Error
More than one error may occur simultaneously. For details of each error, refer to

the FD-S Series Instruction Manual.
*2 Details of output status can be checked by noting the ON/OFF state of each bit.
*3 If the instantaneous flow rate is above the upper limit of display range ("FFFF" is

displayed), the data will be "32767". If it is below the lower limit of display range

("- FFF" is displayed), the data will be "- 32768". If another error is displayed, the

data just b efore the error occurred or the error response (0EH) is displayed.

The data is for "rESo" irrespective of the display mode set on the sensor ampli-

fier.
*4 If the integration flow value is above the upper limit, the upper limit value is

retained. If it is above the lower limit, the lower limit value is retained. If a sensor

amplifier error occurs, the data just before the error occurred or the error

response (0EH) is displayed.

Data is read in minimum display units irrespective of the integrated flow quantity

unit set on the sensor amplifier.
