3 Safety Precautions

!WARNING Do not attempt to take any Unit apart while the power is being supplied. Doing

so may result in electric shock.

!WARNING Do not touch any of the terminals or terminal blocks while the power is being

supplied. Doing so may result in electric shock.

!WARNING Do not attempt to disassemble, repair, or modify any Units. Any attempt to do

so may result in malfunction, fire, or electric shock.

!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:

!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.

• Assembling the Units.

• Setting DIP switches or rotary switches.

• 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.)

6Data Backup

OMRON devices that comply with EC Directives also conform to the related
EMC standards so that they can be more easily built into other devices or
machines. The actual products have been checked for conformity to EMC
standards (see the following note). Whether the products conform to the stan­dards in the system used by the customer, however, must be checked by the
customer.

EMC-related performance of the OMRON devices that comply with EC Direc­tives will vary depending on the configuration, wiring, and other conditions of
the equipment or control panel in which the OMRON devices are installed.
The customer must, therefore, perform final checks to confirm that devices
and the overall machine conform to EMC standards.

1-1-1 Outline

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.

• 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

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
achieved by not holding the EM Area status when power is turned OFF.

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

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.

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.

• Linear sensor control (High-speed trace of in-line quality data) (CS1W­HCA12-V1 only)

• Example) Quality check of high-speed assembling process (injection

With the use of a displacement sensor, the sensor inputs the charac­teristic data of objects flowing at high speed, and the unit' data mem­ory stores the input data at constant intervals.

a) The data can be transferred to the memory card by batch process-

ing, and can be read using the PC for analyses.

b) The data can be transferred to the CPU unit's data memory by

batch processing, and the line plot of the data can be displayed on
the screen of the programmable terminal (NS series by OMRON).

• Operation Process

1) High-speed analog input by scheduled interrupts with the ladder
program (immediate refresh)
The PRV instruction is executed at each of constant executions of
subroutine programs with the scheduled interrupts (interval timer).
4 to 20 mA signals from the displacement sensor are input, re­freshed, and stored (trace data) in the I/O memory area (Ex. DM)
of the main unit.

2) Transferring the traced data to the CPU unit
The data traced in the unit is transferred to the CPU unit. (Ex.
Through the cyclic transfer to DM allocated in the CPU unit)

3) Transferring the data to the memory card inserted in the slot of the
CPU unit
The data in the DM area is stored in the memory card as a data
file (.CSV etc) through the FWRIT instruction of the CPU unit.

4) Analysis performed on the spreadsheet software
Through the memory card adaptor connected to the PC, the data
file (.CSV etc) can be analyzed on the spreadsheet software.

5) Line plot displayed on PT (NS series)
The trace data in the CPU unit can be displayed as the line plot on
PT (NS series).

Note 1. If the switch is turned OFF, Programming Device servicing is not performed

and so the scan time is shorter.

2. This switch can also be used as a restart switch for connection with the
Programming Device.

Peripheral Port The peripheral port is used for connecting to a Programming Device (i.e., a

Support Software installed on a computer or a Programming Console).

Note The Unit automatically recognizes the serial communications mode (i.e., Pro-

gramming Console bus, peripheral bus).

I/O Connector
(All Units)

The I/O connector is for contact I/O. Make a cable for this connector with the
24-pin connector provided with the Unit. (For details, refer to 3-3 Wiring.)

Special I/O Connector
(CS1W-HCP22-V1/HCA22­V1/HCA12-V1 Only)

The special I/O connector is for special I/O: Pulse inputs and pulse outputs for
the CS1W-HCP22-V1, pulse inputs and analog outputs for the CS1W-HCA22­V1, and pulse inputs, analog input and analog outputs for the CS1W-HCA12­V1. Either make a cable for this connector with the 40-pin connector provided
with the Unit, or using a special OMRON cable, connect to an OMRON Con­nector Terminal Conversion Unit. (For details, refer to 3-3 Wiring.)

3-2 Installation

3-2-1 Applicable Racks

The Customizable Counter Unit is a CS-series Special I/O Unit.

• It can be mounted to a CS-series CPU Rack or a CS-series Expansion

• It cannot be mounted to a C200H Expansion Rack or a SYSMAC BUS

The number of Units that can be mounted on one Rack (CPU Rack or Expan­sion Rack) depends on the maximum supply current of the Power Supply Unit
and the current consumption of the other Units.

Note The CIO Area words that are allocated to Special I/O Units depends on the

setting of the unit number switch on the front of the Unit, not on the slot in
which the Unit is mounted.

3-5 Fail-safe Circuits

You must set up safety circuits outside of the Customizable Counter Unit to
prevent dangerous conditions in the event of errors in the Unit or external
power supply. Take particular care of the following points.

!WARNING Take any safety measures necessary outside of the Unit to ensure the safety

of the system in the event of an error due to Unit malfunction or external fac­tors. Failure to do so could lead to a serious accident.

• Provide interlock circuits, limit circuits, emergency stop circuits, and simi­lar safety measures in the PLC’s external control circuits.

• Operation will stop and all contact and pulse outputs will turn OFF when
the PLC detects an error or when a FALS(07) (fatal error) instruction is
executed. You must take any safety measures necessary outside of the
Unit to ensure the safety of the system in the event that all contact and
pulse outputs turn OFF.

• It is possible for an output to remain ON or OFF due to a factors, such as
damage to a transistor in the internal circuit of a contact output. Provide
any circuits necessary outside of the PLC to ensure the safety of the sys­tem in the event that a contact output fails to turn OFF or ON.

• If there is an overload or a short-circuit in the Power Supply Unit’s 24-VDC
output (service power supply), the voltage may drop and the outputs may

56

Fail-safe Circuits Section 3-5

turn OFF. Take any safety measures necessary outside of the Unit to
ensure the safety of the system in the event that outputs turn OFF.

Supply Power to the PLC
before Outputs

If the PLC’s power supply is turned ON after the controlled system’s power
supply, contact outputs may malfunction momentarily and, as a result, the
controlled system’s outputs may operate incorrectly for a short time. To pre­vent any malfunction, add an external circuit that prevents the power supply to
the controlled system from going ON before the power supply to the PLC
itself.

Unit Errors When any of the following fatal errors occur at the Customizable Counter Unit,

the Unit will stop operation (and processing) and all contact outputs and pulse
outputs will be turned OFF:

• A Unit WDT error, a Unit RAM error, a memory error, a no END instruction
error, a FALS instruction execution, or a CYCLE TIME OVER error

Note For analog outputs, either the value set (maximum value, present value, clear)

with the output hold function in the Unit Setup Area (DM 6614) or 0 V will be
output. (For details, refer to 7-7 Analog Outputs.)

Set up safety circuits outside of the Customizable Counter Unit to prevent
dangerous conditions in the event of the above errors.

Contact Output Failures It is possible for an output to remain ON due to a malfunction in the internal

circuitry of a contact output, such as a transistor failure. Provide any circuits
necessary outside of the PLC to ensure the safety of the system in the event
that a contact output fails to turn OFF.

Interlock Circuits When the PLC output controls opposite operations, such as forward and

reverse operation of a motor, or in cases where incorrect PLC operation may
cause an accident or damage to equipment, set up interlock circuits outside
the PLC. An example is given below.

Interlock circuit

Forward rotation of motor

PLC

Reverse rotation of motor

In the above example, if outputs IR 00100 and 00102 both turn ON together
(incorrect operation), the interlock circuit will stop MC1 and MC2 turning ON
together.

If the RUN/STOP Command Bit is enabled (i.e., if word m bits 00 to 07 are
00 Hex), the RUN/Stop Command Bit (word n bit 00) will turn OFF and the
operation of the Customizable Counter Unit will stop.

If the RUN/STOP Command Bit is disabled (i.e., if word m bits 00 to 07 are
01 Hex), the following type of programming is required to turn OFF Cus­tomizable Counter Unit outputs: Turn ON one of the general-purpose bits
in the allocated words in the CIO Area and when the bit turns OFF (as a
result of A50015 turning ON), use it in the Customizable Counter Unit to
turn OFF the outputs.

4-5 Difference between I/O Refreshing in Customizable

Counter Units and That in Other Special I/O Units

The following describes the difference between I/O refreshing in Customiz­able Counter Units and that in other Special I/O Units. Please note that the
time it takes to update data on both sides when a CPU Unit shares data with a
Customizable Counter Unit will significantly affect system operation.

72

Difference between I/O Refreshing in Customizable Section 4-5

Exchanging Data between a Customizable Counter Unit and the CPU Unit

A CS1W-H@@@@ Customizable Counter Unit exchanges data with the CS­series CPU Unit in an asynchronous system using I/O refreshing timing on
both sides. (See Figure 1.)

Figure 1

• The Customizable Counter Unit refreshes its own I/O by reading the
shared memory inside it.

• The CPU Unit, on the other hand, refreshes its own I/O by reading the
shared memory in the Customizable Counter Unit.

This allows the Customizable Counter Unit and the CPU Unit to exchange
data (I/O refreshing). The CPU Unit, however, always has priority in accessing
the shared memory in the Customizable Counter Unit.

If the I/O refresh timing in the Customizable Counter Unit and the CPU Unit
synchronizes by chance, then the Customizable Counter Unit will not refresh
its data because the CPU Unit has priority in accessing the shared memory.
This means that the Customizable Counter Unit may not be refreshed for sev­eral cycles.

Problem The following problem may occur.

■ When the Same Constant Cycle Time Is Set for Both the CPU Unit and the

Customizable Counter Unit

When the constant cycle time function is used to set the same cycle time
interval for the CPU Unit and the Customizable Counter Unit, the I/O refresh
rate for both will overlap in consecutive cycles if the cycles ever become syn­chronized. This means that the Customizable Counter Unit may not refresh
the I/O for several cycles. (See Figure 2.)

Counter Unit

Figure 2

73

Difference between I/O Refreshing in Customizable Section 4-5

Note Even if the same interval is set using the constant cycle time function, syn-

chronization actually will not last long even when it does occur because the
intervals are not that precise. This means that a period of overlap will be fol­lowed by a period of non-overlap.

■ Other Cases

The I/O refresh timing on both sides may or may not overlap consecutively
under certain conditions in items (1) to (3) below.

1. When the cycle times of both the CPU Unit and the Customizable Counter
Unit are constantly changing.

2. When the cycle times of both the CPU Unit and the Customizable Counter
Unit are stable yet different.

3. When the constant cycle time function is used to set a different cycle time
interval for the CPU Unit and the Customizable Counter Unit.

When the I/O Refresh Timing on Both Sides Overlaps Consecutively:

When the CPU Unit cycle time - the Customizable Counter Unit cycle time <
the I/O refresh time of the Customizable Counter Unit in the CPU Unit

When the I/O Refresh Timing on Both Sides Will Not Overlap
Consecutively:

When the CPU Unit cycle time - the Customizable Counter Unit cycle time >
the I/O refresh time for the Customizable Counter Unit in the CPU Unit

Even if the I/O refresh timing on both sides overlaps momentarily, it will not
overlap in the next cycle in these cases. This means that the I/O can be
refreshed (data exchanged) within the maximum output response time (2
cycles) of the PLC. (See Figure 3.)

Note The I/O refresh time for the Customizable Counter Unit under the CPU Unit is

equivalent to the time it takes the CPU Unit to access the shared memory.

Preventing the Customizable Counter Unit from Missing Consecutive I/O Refreshes

■ When the Cycle Time of the CPU Unit Can Be Changed

Use the constant cycle time function on the CPU Unit to change the cycle time
of the Unit so it is longer than the sum total of the cycle time for the Customiz­able Counter Unit and the I/O refresh time of the CPU Unit as expressed by
the formula below.

time

If the cycle time for the CPU Unit cannot be changed because of the effect the
change would have on system performance, then perform steps (1) and (2)
below.

1,2,3... 1. Use the PLC Setup in the CPU Unit to disable cyclic refresh for the Special

I/O Unit number corresponding to the Customizable Counter Unit.

2. Use a timer or some other means to execute the IORF instruction in the
ladder program in the CPU Unit at a time interval longer than the cycle time
of the Customizable Counter Unit. Be sure to refresh the I/O in shared
memory in the Customizable Counter Unit as needed.

Note For customers using -V1 lot No. 0302 or later products

Use the I/O Refresh Monitor Error Flag (CIO 23513 in the Customiz­able Counter Unit, bit 13 word n+5 in the CPU Unit) to verify whether
the Customizable Counter Unit has performed consecutive I/O re­freshes.

Customizable Counter Unit

I/O Refresh Monitor Error Flag: CIO 235 bit 13

CPU Unit

bit 13 in word n+5

This flag turns ON when the number of consecutive I/O refreshes missed in
shared memory by I/O refreshing the Customizable Counter Unit exceeds a
preset monitored count.

The monitored count can be set to any number in bits 08 to 15 in word m+6 in
the initial setting area (word m to m+9) in the DM Area words allocated to the
Counter Unit in the CPU Unit (00: 10 times (default), 01 to FF: (1 to 255)).

If a non-fatal error (FAL 99) occurs with the following ladder program for exam­ple, check the cycle times and change one or the other so the cycle time of
the CPU Unit is longer than the sum total of the cycle time of the Customiz­able Counter Unit and the I/O refresh time of the CPU Unit.

Example: Customizable Counter Unit

235.13
FAL 99

I/O Refresh Monitor Error Flag

This flag turns OFF when the Customizable Counter Unit enters RUN mode,
and turns ON as soon as the number of missed I/O refreshes exceeds the
preset monitored count.

75

Difference between I/O Refreshing in Customizable Section 4-5

Reference: The Customizable Counter Unit refreshes I/O by performing a handshake
with the CPU Unit at any time (with -V1 lot No. 0302 or later Units only)

The Customizable Counter Unit can refresh the I/O by performing a hand­shake with the CPU Unit at any time. Execute the IORF instruction (with oper­ands set to 002 and 002) in the Customizable Counter Unit to refresh the I/O
data in its shared memory. At the same time, start an interrupt task in the CPU
Unit so the IORF instruction can be executed on the shared memory in the
Customizable Counter Unit from within the interrupt task.

Example:
In a ladder program in the Customizable Counter Unit

Refresh launched

[IORF 002 002] Executes I/O refresh on its own shared memory.

In interrupt task No. 10 in the CPU Unit

This way, the Customizable Counter Unit can refresh its data in the CPU Unit
immediately at any specified time.

The Unit Setup Area enables the user to set the functions of the Customizable
Counter Unit through initial software settings. Connect a Programming Device
to the Unit’s peripheral port and make the settings in DM 6600 to DM 6655 of
the Unit’s DM Area.

Note It is not possible to make the settings for the Unit Setup Area in the Customiz-

able Counter Unit from a CX-Programmer using the PLC Setup functions.
Make the settings for in DM 6600 to DM 6655 from the PLC Memory Window
on the CX-Programmer.
