!WARNING Do not touch the Power Supply Unit while power is being supplied or immedi-
ately after power has been turned OFF. Doing so may result in electric shock.
!WARNING Provide safety measures in external circuits, i.e., not in the Programmable
Controller (CPU Unit including associated Units; referred to as “PLC”), in
order to ensure safety in the system if an abnormality occurs due to malfunction of the PLC or another external factor affecting the PLC operation. Not
doing so may result in serious accidents.
xii
Operating Environment Precautions 4
• Emergency stop circuits, interlock circuits, limit circuits, and similar safety
measures must be provided in external control circuits.
• The PLC will turn OFF all outputs when its self-diagnosis function detects
any error or when a severe failure alarm (FALS) instruction is executed.
As a countermeasure for such errors, external safety measures must be
provided to ensure safety in the system.
• The PLC outputs may remain ON or OFF due to deposition or burning of
the output relays or destruction of the output transistors. As a countermeasure for such problems, external safety measures must be provided
to ensure safety in the system.
• When the 24-VDC output (service power supply to the PLC) is overloaded
or short-circuited, the voltage may drop and result in the outputs being
turned OFF. As a countermeasure for such problems, external safety
measures must be provided to ensure safety in the system.
!Caution Execute online edit only after confirming that no adverse effects will be
caused by extending the cycle time. Otherwise, the input signals may not be
readable.
!Caution Confirm safety at the destination node before transferring a program to
another node or changing contents of the I/O memory area. Doing either of
these without confirming safety may result in injury.
!Caution Tighten the screws on the terminal block of the AC power supply to the torque
specified in the operation manual. The loose screws may result in burning or
malfunction.
4 Operating Environment Precautions
!Caution Do not operate the control system in the following locations:
• Locations subject to direct sunlight.
• Locations subject to temperatures or humidity outside the range specified
in the specifications.
• Locations subject to condensation as the result of severe changes in temperature.
• Locations subject to corrosive or flammable gases.
• Locations subject to dust (especially iron dust) or salts.
• Locations subject to exposure to water, oil, or chemicals.
• Locations subject to shock or vibration.
!Caution Take appropriate and sufficient countermeasures when installing systems in
the following locations:

longevity and reliability of the system. Improper operating environments can
lead to malfunction, failure, and other unforeseeable problems with the PLC
System. Be sure that the operating environment is within the specified conditions at installation and remains within the specified conditions during the life
of the system.
5 Application Precautions
!WARNING Always heed these precautions. Failure to abide by the following precautions
could lead to serious or possibly fatal injury.
• Always connect to a ground of 100
connecting to a ground of 100
• A ground of 100
terminals on the Power Supply Unit.
• Always turn OFF the power supply to the PLC before attempting any of
the following. Not turning OFF the power supply may result in malfunction
or electric shock.
• Mounting or dismounting Power Supply Units, I/O Units, CPU Units, Inner Boards, or any other Units.

• Connecting cables or wiring the system.
• Connecting or disconnecting the connectors.
!Caution Failure to abide by the following precautions could lead to faulty operation of
the PLC or the system, or could damage the PLC or PLC Units. Always heed
these precautions.
• Always turn ON power to the PLC before turning ON power to the control
system. If the PLC power supply is turned ON after the control power supply, temporary errors may result in control system signals because the
output terminals on DC Output Units and other Units will momentarily turn
ON when power is turned ON to the PLC.
• Fail-safe measures must be taken by the customer to ensure safety in the
event that outputs from Output Units remain ON as a result of internal circuit failures, which can occur in relays, transistors, and other elements.
• Fail-safe measures must be taken by the customer to ensure safety in the
event of incorrect, missing, or abnormal signals caused by broken signal
lines, momentary power interruptions, or other causes.
• Interlock circuits, limit circuits, and similar safety measures in external circuits (i.e., not in the Programmable Controller) must be provided by the
customer.
• Always use the power supply voltages specified in the operation manuals.
An incorrect voltage may result in malfunction or burning.
• Take appropriate measures to ensure that the specified power with the
rated voltage and frequency is supplied in places where the power supply
is unstable. An incorrect power supply may result in malfunction.
W or less must be installed when shorting the GR and LG
W or less when installing the Units. Not
W or less may result in electric shock.
xiv
Application Precautions 5
• Install external breakers and take other safety measures against short-circuiting in external wiring. Insufficient safety measures against short-circuiting may result in burning.
• Do not apply voltages to the Input Units in excess of the rated input voltage. Excess voltages may result in burning.
• Do not apply voltages or connect loads to the Output Units in excess of
the maximum switching capacity. Excess voltage or loads may result in
burning.
• Disconnect the functional ground terminal when performing withstand
voltage tests. Not disconnecting the functional ground terminal may result
in burning.
• Install the Units properly as specified in the operation manuals. Improper
installation of the Units may result in malfunction.
• Be sure that all the mounting screws, terminal screws, and cable connector screws are tightened to the torque specified in the relevant manuals.
Incorrect tightening torque may result in malfunction.
• Leave the label attached to the Unit when wiring. Removing the label may
result in malfunction if foreign matter enters the Unit.
• Remove the label after the completion of wiring to ensure proper heat dissipation. Leaving the label attached may result in malfunction.
• Use crimp terminals for wiring. Do not connect bare stranded wires
directly to terminals. Connection of bare stranded wires may result in
burning.
• Wire all connections correctly.
• Double-check all wiring and switch settings before turning ON the power
supply. Incorrect wiring may result in burning.
• Mount Units only after checking terminal blocks and connectors completely.
• Be sure that the terminal blocks, Memory Units, expansion cables, and
other items with locking devices are properly locked into place. Improper
locking may result in malfunction.
• Check switch settings, the contents of the DM Area, and other preparations before starting operation. Starting operation without the proper settings or data may result in an unexpected operation.
• Check the user program for proper execution before actually running it on
the Unit. Not checking the program may result in an unexpected operation.
• Confirm that no adverse effect will occur in the system before attempting
any of the following. Not doing so may result in an unexpected operation.
• Changing the operating mode of the PLC.
• Force-setting/force-resetting any bit in memory.
• Changing the present value of any word or any set value in memory.
• Resume operation only after transferring to the new CPU Unit the contents of the DM Area, HR Area, and other data required for resuming
operation. Not doing so may result in an unexpected operation.
• Do not pull on the cables or bend the cables beyond their natural limit.
Doing either of these may break the cables.
• Do not place objects on top of the cables or other wiring lines. Doing so
may break the cables.
xv
Data Backup 6
• When replacing parts, be sure to confirm that the rating of a new part is
correct. Not doing so may result in malfunction or burning.
• Before touching a Unit, be sure to first touch a grounded metallic object in
order to discharge any static build-up. Not doing so may result in malfunction or damage.
• When transporting or storing circuit boards, cover them in antistatic material to protect them from static electricity and maintain the proper storage
temperature.
• Do not touch circuit boards or the components mounted to them with your
bare hands. There are sharp leads and other parts on the boards that
may cause injury if handled improperly.
• Data in the DM Area, error log, EM Area, or Timer/Counter Area may
become corrupted if power is not supplied for an extended period of time.
Program the PLC to check SR 24914 before starting operation. If SR
24914 is ON, the memory areas that are normally held during power interruptions will not have been held properly (i.e., the data will be corrupted).
(The data in the DM Area can be backed up to flash memory by turning
ON SR 25200.)

The Customizable Counter Units are CS-series Special I/O Units that can be
programmed using a ladder program and provide both standard contact I/O
and special I/O (including pulse inputs, pulse outputs, and analog outputs).
(I/O support depends on the model of the Unit.)
The I/O of a Customizable Counter Unit can be controlled by the ladder program in it without intervention from the program in the CPU Unit to achieve
high-speed I/O processing. By customizing a Customizable Counter Unit
using its I/O, programming, and interrupt functions, a wide range of applications requiring high-speed response can be implemented in a distributed processing system where the Customizable Counter Unit functions as a
coprocessor for the CPU Unit.
Customizable Counter Unit capabilities also facilitate machine modularization
and standardization, and make machine and device maintenance much easier.

CS-series CPU Unit
• High-speed I/O processing is enabled by the small-capacity ladder program in the Customizable Counter Unit that achieves a high-speed cycle.
The Customizable Counter Unit also supports various types of interrupt
programming, enabling it to handle special high-speed applications previously handled by sensor controllers and microcomputer boards. The Customizable Counter Unit can also perform part of the functions previously
performed by High-speed Counter Units, Position Control Units, and Analog Output Units.
• Other features include normal interrupts, interval timer interrupts, and
high-speed counter interrupts, in addition to a high-precision timer that
uses a pulse counter (CS1W-HCP22-V1 only), target value interrupts for
a pulse output value (CS1W-HCP22-V1 only), analog output instructions
for analog slope control (CS1W-HCA22-V1 only), and range comparisons
for the present value of a high-precision pulse output counter timer.
• The CS1W-HCA12-V1 is a special I/O unit of CS-series, having all of 1
high-speed analog input, 1 pulse input (compatible with servo drivers with
absolute encoders), 2 high-speed analog outputs, and operations by builtin ladder program (simplified positioning, discriminant and counting processes) within 1 unit. The unit by itself can process both the "linear sensor

control" and "simplified position/speed control", which have been processed separately by the dedicated unit or system in existing models.
1) High-speed input of analog signals from displacement sensors etc,
which have been processed in the linear sensor controller in the existing system, enables the ladder program processing.
2) This unit can perform the simplified position controls that have been
operated with motion control and position control units in the existing
system. Taking in the encoder signals enables the unit to drive the servo driver with analog output. In addition, using the other analog output
makes it possible to limit the torque and control inverters.

Outline Section 1-1
1-1-2 Features
Programmable I/O Control • The program capacity for the ladder program in the Customizable Counter
Unit is 4 Kwords.
• Standard features include 12 contact inputs and 8 contact outputs.
• For special I/O, the CS1W-HCP22-V1 provides 2 pulse inputs and 2 pulse
outputs, while the CS1W-HCA22-V1 provides 2 pulse inputs and 2 analog
outputs.
• Pulse inputs on the CS1W-HCP22-V1 and CS1W-HCA22-V1 can be used
for a high-speed counter (50 or 200 kHz, signal phase), and the present
value of the counter can be used to create target value interrupts or range
comparison bit pattern outputs. Trapezoid pulse (speed) outputs or conditional ON/OFF outputs can thus be created for the present value pulse
input. Furthermore, an Electronic Cam Mode can be used to change the
pulse output value for absolute positioning or the pulse output frequency
for speed control in response to the present value of the pulse input (e.g.,
for a rotational angle). You can also monitor changes in the present value
of the high-speed counter or measure the frequency from the present
value of the high-speed counter.
• Pulse outputs on the CS1W-HCP22-V1 can be used for specified frequency outputs with or without acceleration/deceleration, as well as for
one-shot outputs (turned ON for a specified time between 0.01 and
9,999 ms). The one-shot pulse output function can also be used to
achieve a high-precision pulse counter timer with a minimum time of
0.01 ms, and the present value can be used to create target value interrupts or range comparison bit pattern outputs. Trapezoid pulse (speed)
outputs or conditional ON/OFF outputs can thus be created for the
present value of the pulse output.
• Analog outputs on the CS1W-HCA22-V1 can be used with the SPED or
ACC instruction to step analog outputs or for rising or falling sloped outputs.
• Combinations with timer instructions enable time-stepped or trapezoid
analog outputs.
• Analog outputs can be set to be held at the peak, current, or cleared
value by turning OFF an Output Conversion Enable Bit when required
or for errors.
• The SPED and ACC instructions can be used to control the analog output value independent of the END refresh.
• The I/O refresh time can be reduced by disabling the analog outputs
when they are not required.
• Rate-of-change measurements are possible at a sampling time for the
high-speed counter input.
• High-speed counter input frequency measurements can be taken.
• The present value of the high-speed counters can be cleared or held
when power is turned ON.
• The high-speed counters can be started and started by controlling the
status of a control bit.
• Any of four pulse output ranges can be specified: 6 Hz to 20 kHz, 25 Hz to
50 kHz, 100 Hz to 100 kHz, or 400 Hz to 200 kHz.
• The present value of the pulse output can be reset.

Advanced Processing • Either high-speed or normal-speed execution can be selected for basic
instructions. The execution time for basic instructions in High-speed Execution Mode is approximately twice as fast as the time in Normal Execution Mode. (The program must be approximately 1 Kword or less to use
High-speed Execution Mode.) (Example for LD instruction: Normal Execution: 0.4
• Faster execution of CTBL and other instructions using table data can be

Coordinating Operation
with the CPU Unit
Special I/Os that Can
Support Various
Applications
• Data can be exchanged in three different areas of memory shared with
the CPU Unit to perform handshaking and other operations without programming a special interface.
• Ten words of the CIO Area in the CPU Unit are shared with SR Area
Words in the Customizable Counter Unit.
• Up to 90 words of the DM Area in the CPU Unit can be shared with
user-set words in the Customizable Counter Unit.
• Up to 32 user-set words in the CPU Unit can be shared with LR Area
words in the Customizable Counter Unit.
• External interrupt tasks in the CPU Unit can be executed by programming
the MCRO instruction in the Customizable Counter Unit. The Customizable Counter Unit can thus activate programming in the CPU Unit
depending on the control status of the Customizable Counter Unit to synchronize processing with other Units.
• 1 high-speed analog input (CS1W-HCA12-V1)
High-speed analog input (A/D conversion time = 50
ports 0 to 10 V, 1 to 5 V,
enables the control supporting the analog input from the displacement
and pressure sensors through the linear sensor.
• 2 high-speed analog outputs (CS1W-HCA12-V1)
High-speed analog output (D/A conversion time = 50
supports 0 to 10 V, 1 to 5 V,
and the use of servo drivers of an analog input type enables the speed
control, torque commands, etc. in addition, it can be used for the inverter
control (frequency commands).
• 1 input for taking in the absolute encoder output data (CS1W-HCP22-V1/
HCA22-V1/HCA12-V1)
With this input, it is possible to take in the absolute encoder output data
directly from the servo drivers manufactured by OMRON, etc. Since it
enables the feedback input of the absolute value information, the analog
output mentioned above can be used for position control.

These units has the built-in ladder programs. It is possible to encapsulate the
programs as the ladder library. The ladder library is saved to the Flash memory in the unit. The encapsulation of the programs to the library enables the
"protection of the ladder software assets from the third party" and "execution
of the ladder software functions quasi-without programming".
Through the bit manipulation from the CPU unit, it is possible to back up
(write) or restore (read) the data of the unit to or from the memory card. With
the use of CS1-H CPU units, the data can be backed up or restored through
the simplified back-up operation on the front panel of the CPU unit.
Outline Section 1-1
1-1-3 Application Examples
The following are a few examples of the types of applications that are possible
by combining various features.
• Contact Input
High-speed interrupt I/O processing or IORF instruction execution can be
used to refresh outputs whenever required.
• Pulse Input
• An Electronic Cam Mode can be used to perform a specific absolute
positioning operation and speed change for the rotational angle or current position of a workpiece. For example, the encoder output from a
main control axis can be input to the high-speed counter, and a specified movement for a target position (number of output pulses) for the
followup axis can be defined using linear approximation with the APR
instruction. The PULS instruction can also be used to change the number of output pulses (target position) based on the defined value to
change the pulse output during operation.
• Speed control via a pulse output can be achieved in response to the
position of a workpiece. The present value of either a high-speed
counter or pulse output can be used with a target value interrupt for an
interrupt program that contains an instruction to change the frequency,
i.e., SPED or ACC.
• High-speed processing, such as for coating or valve control, can be
achieved for a fast-moving object by outputting a one-shot output pulse
with a minimum unit of 0.01 ms from a specified position. This is
achieved by combining an interrupt for the present value of a pulse input, and then programming a one-shot pulse output using the STIM instruction in the interrupt program.
• Pulse Input
• Simple positioning with an analog output can be achieved with an inverter and motor. This is achieved by combining an interrupt for the
present value of a pulse input, and then programming a stepped analog output using the SPED instruction or a slopped analog output using
the ACC instruction in the interrupt program.
• Trapezoid torque control with an analog output for the position of a
workpiece. This is achieved by combining an interrupt for the present
value of a pulse input, and then programming a slopped analog output
using the ACC instruction in the interrupt program.
• Trapezoid analog output for a specified time can be achieved by combining a timer instruction with a slopped analog output using the ACC
instruction.
• Torque control (Clamping in molding applications, transfer control in injection-molding applications) (CS1W-HCA12-V1 only)
pressure control (speed control and torque limit)
• Using this unit with a servo driver of an analog input type and a pressure sensor enables the control as described below. Note that the servo driver (W series manufactured by OMRON in the example) is to be
in the "speed control" mode.

• Operation Process
1) Position control by the unit (CS1W-HCA12-V1):
A speed command is issued to the servo driver with the analog
output. The servo driver feeds back the absolute position information with the absolute encoder input. Using the feedback, position control is executed (through the speed command output)
following SPED or ACC instructions on the ladder program of the
unit.
2) Pressure control by the unit (speed control and torque limit):
Reaching a certain position (position for pressure control) causes the unit to output a speed and a torque limit command for the
speed control and torque limit. The pressure control (clamping
etc) is executed after the unit converts the analog inputs (load
cell, strain gauge, etc) from the pressure sensor to the analog
outputs (torque limit by the speed command and torque limit output) for the servo driver.
3) Position control by the unit
Once the operation (molding, etc) is completed, a speed command output from the unit returns the mechanical system to its
origin.

• Linear sensor control (control based on monitoring the ups and downs/
distortion/thickness/height/diameter of objects) (CS1W-HCA12-V1 only)
• Example) Counting ups and downs (piles)
With the use of a displacement sensor, the unit can count the number
of ups and downs (piles) by monitoring the change in the displacement
amount as the sensor measures them on the surface of objects moving at high speed.

Moving at high speed
1) High-speed analog input (immediate refresh)
4 to 20 mA signals from the displacement sensor are input to and
refreshed in the unit at every PRV instruction execution. The displacement data is stored in the areas (Ex: DM) that have the I/O
memory.
2) Counting process with the ladder program
A ladder program has to be arranged (Ex: The unit compares the
ranges with BCMP instruction, and the unit counts rises of the results with INC instruction) so that the counter will count the number
of times of when the stored displacement data exceed a certain
threshold value. The execution of the program will make the unit
count.
