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 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.

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.

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

• Communicate the output signal, judgment value, and 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.

• If either the external input via communication or the input signal line
of the sensor amplifier is ON, the amplifier unit recognizes that the
external input is ON and thus executes input operation (ORing).
Example: Suppose that the external input n is set to "reset input." The
reset input is executed if the external input via communication or the
input signal line of the sensor amplifier is ON.

• In cases of using the BANK change function, set the "BANK change
method" parameter of the amplifier unit to "external input change."

Reading Judgment Values (P.V. Values) from Sensor Amplifiers

Judgment values (P.V. values) can be read in the monitor modes and full modes.
They cannot be read in small-memory modes.

Monitor mode 1

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

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

When reading judgment values in monitor mode 2 or full mode, see "Monitor
mode 2/full mode" (page 3-20).

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

judgment value change process. Check the values specified in the "select judgment value box page

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

value boxes 1 to 3.
If the judgment value is correct, the parameter range is

・ from - 99.999 to 99.999 (SK-050).

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 judgment value page" command is set to 0, the "judgment value page

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

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

updated by cyclic transfer.

Monitor mode 2/full mode

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

Communicating with the SK-1000 Series

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

When reading judgment values (P.V. values) in monitor mode 1, see "Monitor
mode 1" (page 3-19).

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

remote register RWr.
If the judgment value is correct, the parameter range is

・ from - 99.999 to 99.999 (SK-050).

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.

(2) If the judgment value of a sensor amplifier is "invalid," the bit corresponding to the ID number of that

sensor amplifier flips to 1.

(3) If the judgmen

sensor amplifier flips to 1.

(4) If the judgment value of a sensor amplifier is "under," the bit corresponding to the ID number of that

sensor amplifier flips to 1.

Changing the BANK Number of Sensor Amplifiers

This example changes the BANK number associated with ID01 and ID02.
(1) Specify a new BANK number in "select BANK number" and execute "request to change BANK" (0 ->

1). In this example, the BANK is changed for both ID01 and ID02 simultaneously.

(2) The "BANK change complete" signal flips from 0 to 1 when the change to the specified BANK

number is completed.

(3) When the "request to change BANK" command is set to 0, the "BANK change complete" parameter

flips to 0.

(4) If an error occurs while changing the BANK for a sensor amplifier of any ID number, the "BANK

change error" signal flips from 0 to 1 (the output is the logical disjunction (OR) for IDs 01 to 04).
Check the value specified in the "select BANK numb er" parameter.

(5) To clear the BANK change error, set the "clear BANK change error" parameter to 1.

Executes zero shift. Turning off the
power to the sensor amplifier after
executing zero shift restores the state
that existed before the zero shift
function was used. If to retain the
shifted state after turning off the
power, turn on the zero shift value
memory function.

Initializes all settings, except for
sensor amplifier calibration, reference
light intensity registration, and system
parameters. Once an initial reset
request is executed, all parameters
are stored into the nonvolatile
memory (EEPROM) in approximately
three seconds. After finished, the
setting/status command parameter
"EEPROM writing result" flips to
"successfully completed (1)".

Changes the system parameters (the
settings of "judgment ou tput/alarm
output" polarity and analog output) to
the settings contained in the setting/
status command parameter "system
parameter."
When executing a system parameter
set, ensure that the settings are
changed correctly to suit the
connected equipment and wiring. A
wrong change may damage the
sensor amplifier or the connected
equipment.

3-4 Command Parameter List

Setting/status command parameters

For the communication methods using setting/status parameters, see "Reading/
Writing Settings or Status of a Sensor Amplifier" (page 3-23).
To reduce the number of writes to the EEPROM, a write command is executed two
seconds after it is received. If another command is received within 2 seconds, the DL­CL1 waits for another 2 seconds before executing the two commands in batch.
After the writing completes successfully, the "EEPROM writing result" parameter
becomes "successfully completed (1)." For example, if commands are received

continually every second, they do not get executed because the DL-CL1 remains
"currently writing (0)." 2 seconds after the last command is received, the commands
received until then get executed in batch.
If data with a decimal point is used for a parameter range, ignore the decimal point
and read or write the data as an integer. For example, to wri

*3 Use this parameter in combination with the judgment value property or with the

judgment value "invalid," "over," or "under."
If the judgment value is correct, the parameter range is from - 99.997 to 99.998

・ from - 99.999 to 99.999 (SK-050).

• When the current value is over range, "99.999" is stored.
When the current value is under range, "- 99.999" is stored.
When the current value is invalid, "- 99.998" is stored.
When an error occurs, "100.000" is stored.

*9 The result of the "initial reset request" motion command is included in this item.

Regarding Data No. nn35 (EEPROM writing result), a "0: writing in progress"
status is maintained for 2 seconds after completion of the final write command
transmission to the nonvolatile memory (EEPROM). Writing begins 2 seconds
later, and if completed normally, the result is "1: successfully completed".
[Example] After every-second write command transmissions, a "0: writing in

progress" status is established for 2 seconds. A "0: writing in prog­ress" status is maintained for 2 seconds after completion of the final
write command transmission, and writ

ter, with a result of "1: successfully completed".

However, writing begins immediately following a initial reset executed in
response to a Data No. nn05 "initial reset request". A "1: successfully com­pleted" result then occurs if all parameters have been saved to the nonvolatile
memory (EEPROM) approximately 3 seconds later.

- When "zero shift status save" is ON, writing begins immediately for Data No.

3-4 Command Parameter List

*11 By reading the "system parameter current state," the system parameters of the

sensor amplifier can be checked. The system parameters are comprised of the
settings of "judgment output/alarm output" polarity and analog output.
The "system parameter" attribute specifies the system parameters which are set
when the "system parameter set request" is executed by a motion command.
The values to be read or written are specified by translating them to binaries and
using ON or OFF in each bit of the binaries.

Communicating with the SK-1000 Series

*12 This parameter works if "Bank switching method" is set to "button."
*13 These parameters are OFF only if data "0" is written and the wiring is configured

to turn off external input.

*15 To have the sensor amplifier reflect the settings written in data numbers nn92 to

nn95, it is necessary to set data number nn91 to "1" (user setting), or to set the
external input to "user setting" via button operation on the sensor amplifier.

*16 The read value of the two-digit value can be translated to a binary number, so

that the ON/OFF state of each bit can be noted to know the status of judgment
output and alarm output.

Assume the read data is "006":
Translating "6" to a binary number gives "0110".
