About this Manual:

This manual describes installation and operation of the CP-series Programmable Controllers (PLCs)
and includes the sections described below. The CP Series provides advanced package-type PLCs
based on OMRON’s advanced control technologies and vast experience in automated control.

Please read this manual carefully and be sure you understand the information provided before
attempting to install or operate a CP-series PLC. Be sure to read the precautions provided in the fol­lowing section.

Definition of the CP Series

The CP Series is centered around the CP1H CPU Units and is designed with the same basic architec­ture as the CS and CJ Series. The Special I/O Units and CPU Bus Units of the CJ Series can thus be
used. CJ-series Basic I/O Units, however, cannot be used. Always use CP-series Expansion Units and
CP-series Expansion I/O Units when expanding I/O capacity.

I/O words are allocated in the same way as the CPM1A/CPM2A PLCs, i.e., using fixed areas for inputs
and outputs.

fied purpose and under the specified conditions, especially in applications that
can directly or indirectly affect human life. You must consult with your OMRON
representative before applying a PLC System to the above-mentioned appli­cations.

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 Provide safety measures in external circuits (i.e., not in the Programmable

Controller), including the following items, 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.

• Emergency stop circuits, interlock circuits, limit circuits, and similar safety
measures must be provided in external control circuits.

xxv

Safety Precautions 3

• 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 or outputs may remain ON or OFF due to deposits on 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-V DC 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.

!WARNING 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. Not doing so may result in
serious accidents.

!WARNING Do not apply the voltage/current outside the specified range to this unit. It may

cause a malfunction or fire.

!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 editing the I/O 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 this manual. The loose screws may result in burning or malfunc­tion.

!Caution Do not touch anywhere near the power supply parts or I/O terminals while the

power is ON, and immediately after turning OFF the power. The hot surface
may cause burn injury.

!Caution Pay careful attention to the polarities (+/-) when wiring the DC power supply. A

wrong connection may cause malfunction of the system.

xxvi

Operating Environment Precautions 4

!Caution When connecting the PLC to a computer or other peripheral device, either

ground the 0 V side of the external power supply or do not ground the external
power supply at all. Otherwise the external power supply may be shorted
depending on the connection methods of the peripheral device. DO NOT
ground the 24 V side of the external power supply, as shown in the following
diagram.

!Caution After programming (or reprogramming) using the IOWR instruction, confirm

that correct operation is possible with the new ladder program and data before
starting actual operation. Any irregularities may cause the product to stop
operating, resulting in unexpected operation in machinery or equipment.

!Caution The CP1H CPU Units automatically back up the user program and parameter

data to flash memory when these are written to the CPU Unit. I/O memory
(including the DM Area, counter present values and Completion Flags, and
HR Area), however, is not written to flash memory. The DM Area, counter
present values and Completion Flags, and HR Area can be held during power
interruptions with a battery. If there is a battery error, the contents of these
areas may not be accurate after a power interruption. If the contents of the
DM Area, counter present values and Completion Flags, and HR Area are
used to control external outputs, prevent inappropriate outputs from being
made whenever the Battery Error Flag (A402.04) is ON.

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:

• Locations subject to static electricity or other forms of noise.

• Locations subject to strong electromagnetic fields.

!Caution The operating environment of the PLC System can have a large effect on the

longevity and reliability of the system. Improper operating environments can
lead to malfunction, failure, and other unforeseeable problems with the PLC
System. Make 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

Observe the following precautions when using the PLC System.

!WARNING Always heed these precautions. Failure to abide by the following precautions

could lead to serious or possibly fatal injury.

• Always connect to 100 Ω or less when installing the Units. Not connecting
to a ground of 100 Ω or less may result in electric shock.

• 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 Expansion Units or any other Units

• Connecting or removing the Memory Cassette or Option Board

• Setting DIP switches or rotary switches

• Connecting or wiring the cables

• 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.

• Install external breakers and take other safety measures against short-cir­cuiting in external wiring. Insufficient safety measures against short-cir­cuiting may result in burning.

• Mount the Unit only after checking the connectors and terminal blocks
completely.

• Be sure that all the terminal screws and cable connector screws are tight­ened to the torque specified in the relevant manuals. Incorrect tightening
torque may result in malfunction.

• Wire all connections correctly according to instructions in this manual.

• Always use the power supply voltage 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. Be particularly careful in places
where the power supply is unstable. An incorrect power supply may result
in malfunction.

• Leave the label attached to the Unit when wiring. Removing the label may
result in malfunction.

xxviii

Application Precautions 5

• 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.

• Do not apply voltages to the input terminals in excess of the rated input
voltage. Excess voltages may result in burning.

• Do not apply voltages or connect loads to the output terminals in excess
of the maximum switching capacity. Excess voltage or loads may result in
burning.

• Be sure that the terminal blocks, connectors, Option Boards, and other
items with locking devices are properly locked into place. Improper locking
may result in malfunction.

• Disconnect the functional ground terminal when performing withstand
voltage tests. Not disconnecting the functional ground terminal may result
in burning.

• Wire correctly and double-check all the wiring or the setting switches
before turning ON the power supply. Incorrect wiring may result in burn­ing.

• Check that the DIP switches and data memory (DM) are properly set
before starting 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.

• Resume operation only after transferring to the new CPU Unit and/or Spe­cial I/O Units the contents of the DM, HR, and CNT Areas required for
resuming operation. Not doing so 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 (including the setting of the
startup operating mode).

• Force-setting/force-resetting any bit in memory.

• Changing the present value of any word or any set value in memory.

• 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. Doing so may break the cables.

• 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 the Unit, be sure to first touch a grounded metallic object
in order to discharge any static buildup. Not doing so may result in mal­function or damage.

• Do not touch the Expansion I/O Unit Connecting Cable while the power is
being supplied in order to prevent malfunction due to static electricity.

• Do not turn OFF the power supply to the Unit while data is being trans­ferred.

• When transporting or storing the product, cover the PCBs and the Units or
put there in the antistatic bag with electrically conductive materials to pre­vent LSls and ICs from being damaged by static electricity, and also keep
the product within the specified storage temperature range.

xxix

Application Precautions 5

• Do not touch the mounted parts or the rear surface of PCBs because
PCBs have sharp edges such as electrical leads.

• Double-check the pin numbers when assembling and wiring the connec­tors.

• Wire correctly according to specified procedures.

• Do not connect pin 6 (+5V) on the RS-232C Option Board on the CPU
Unit to any external device other than the NT-AL001 or CJ1W-CIF11 Con­version Adapter. The external device and the CPU Unit may be damaged.

• Use the dedicated connecting cables specified in this manual to connect
the Units. Using commercially available RS-232C computer cables may
cause failures in external devices or the CPU Unit.

• Check that data link tables and parameters are properly set before start­ing operation. Not doing so may result in unexpected operation. Even if
the tables and parameters are properly set, confirm that no adverse
effects will occur in the system before running or stopping data links.

• Transfer a routing table to the CPU Unit only after confirming that no
adverse effects will be caused by restarting CPU Bus Units, which is auto­matically done to make the new tables effective.

• The user program and parameter area data in the CPU Unit is backed up
in the built-in flash memory. The BKUP indicator will light on the front of
the CPU Unit when the backup operation is in progress. Do not turn OFF
the power supply to the CPU Unit when the BKUP indicator is lit. The data
will not be backed up if power is turned OFF.

• Do not turn OFF the power supply to the PLC while the Memory Cassette
is being accessed. Doing so may corrupt the data in the Memory Cas­sette. The 7-segment LED will light to indicate writing progress while the
Memory Cassette is being accessed. Wait for the LED display to go out
before turning OFF the power supply to the PLC.

• Before replacing the battery, supply power to the CPU Unit for at least 5
minutes and then complete battery replacement within 5 minutes of turn
OFF the power supply. Memory data may be corrupted if this precaution is
not observed.

• Always use the following size wire when connecting I/O Units, Special I/O
Units, and CPU Bus Units: AWG22 to AWG18 (0.32 to 0.82 mm

2

).

• UL standards required that batteries be replaced only by experienced
technicians. Do not allow unqualified persons to replace batteries. Also,
always follow the replacement procedure provided in the manual.

• Never short-circuit the positive and negative terminals of a battery or
charge, disassemble, heat, or incinerate the battery. Do not subject the
battery to strong shocks or deform the barry by applying pressure. Doing
any of these may result in leakage, rupture, heat generation, or ignition of
the battery. Dispose of any battery that has been dropped on the floor or
otherwise subjected to excessive shock. Batteries that have been sub­jected to shock may leak if they are used.

• Always construct external circuits so that the power to the PLC it turned
ON before the power to the control system is turned ON. 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.

xxx

Conformance to EC Directives 6

• 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.

• If the I/O Hold Bit is turned ON, the outputs from the PLC will not be
turned OFF and will maintain their previous status when the PLC is
switched from RUN or MONITOR mode to PROGRAM mode. Make sure
that the external loads will not produce dangerous conditions when this
occurs. (When operation stops for a fatal error, including those produced
with the FALS(007) instruction, all outputs from Output Unit will be turned
OFF and only the internal output status will be maintained.)

• Dispose of the product and batteries according to local ordinances as
they apply.
Have qualified specialists properly dispose of used batteries as industrial
waste.

overall machine. 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 on which the OMRON devices are installed.
The customer must, therefore, perform the final check to confirm that devices
and the overall machine conform to EMC standards.

Note The applicable EMC (Electromagnetic Compatibility) standard is EN61131-2.

Low Voltage Directive

Always ensure that devices operating at voltages of 50 to 1,000 V AC and 75
to 1,500 V DC meet the required safety standards for the PLC (EN61131-2).

Conformance to EC Directives 6

6-3 Conformance to EC Directives

The CP1H PLCs comply with EC Directives. To ensure that the machine or
device in which the CP1H PLC is used complies with EC Directives, the PLC
must be installed as follows:

1,2,3... 1. The CP1H PLC must be installed within a control panel.

2. You must use reinforced insulation or double insulation for the DC power
supplies used for I/O Units and CPU Units requiring DC power. The output
holding time must be 10 ms minimum for the DC power supply connected
to the power supply terminals on Units requiring DC power.

3. CP1H PLCs complying with EC Directives also conform to EN61131-2.
Radiated emission characteristics (10-m regulations) may vary depending
on the configuration of the control panel used, other devices connected to
the control panel, wiring, and other conditions. You must therefore confirm
that the overall machine or equipment complies with EC Directives.

6-4 Relay Output Noise Reduction Methods

The CP1H PLCs conforms to the Common Emission Standards (EN61131-2)
of the EMC Directives. However, noise generated by relay output switching
may not satisfy these Standards. In such a case, a noise filter must be con­nected to the load side or other appropriate countermeasures must be pro­vided external to the PLC.

Countermeasures taken to satisfy the standards vary depending on the
devices on the load side, wiring, configuration of machines, etc. Following are
examples of countermeasures for reducing the generated noise.

Countermeasures

Countermeasures are not required if the frequency of load switching for the
whole system with the PLC included is less than 5 times per minute.

Countermeasures are required if the frequency of load switching for the whole
system with the PLC included is more than 5 times per minute.

Note Refer to EN61131-2 for more details.

Conformance to EC Directives 6

Countermeasure Examples

When switching an inductive load, connect an surge protector, diodes, etc., in
parallel with the load or contact as shown below.

When switching a load with a high inrush current such as an incandescent
lamp, suppress the inrush current as shown below.

Circuit Current Characteristic Required element

AC DC

Yes Yes If the load is a relay or solenoid, there is

a time lag between the moment the cir­cuit is opened and the moment the load
is reset.

If the supply voltage is 24 or 48 V, insert
the surge protector in parallel with the
load. If the supply voltage is 100 to
200 V, insert the surge protector
between the contacts.

The capacitance of the capacitor must
be 1 to 0.5 µF per contact current of
1 A and resistance of the resistor must
be 0.5 to 1 Ω per contact voltage of 1 V.
These values, however, vary with the
load and the characteristics of the
relay. Decide these values from experi­ments, and take into consideration that
the capacitance suppresses spark dis­charge when the contacts are sepa­rated and the resistance limits the
current that flows into the load when
the circuit is closed again.

The dielectric strength of the capacitor
must be 200 to 300 V. If the circuit is an
AC circuit, use a capacitor with no
polarity.

No Yes The diode connected in parallel with

the load changes energy accumulated
by the coil into a current, which then
flows into the coil so that the current will
be converted into Joule heat by the
resistance of the inductive load.

This time lag, between the moment the
circuit is opened and the moment the
load is reset, caused by this method is
longer than that caused by the CR
method.

The reversed dielectric strength value
of the diode must be at least 10 times
as large as the circuit voltage value.
The forward current of the diode must
be the same as or larger than the load
current.

The reversed dielectric strength value
of the diode may be two to three times
larger than the supply voltage if the
surge protector is applied to electronic
circuits with low circuit voltages.

Yes Yes The varistor method prevents the impo-

sition of high voltage between the con­tacts by using the constant voltage
characteristic of the varistor. There is
time lag between the moment the cir­cuit is opened and the moment the load
is reset.

If the supply voltage is 24 or 48 V, insert
the varistor in parallel with the load. If
the supply voltage is 100 to 200 V,
insert the varistor between the con­tacts.

1-1 Features and Main Functions

1-1-1 CP1H Overview

The SYSMAC CP1H is an advanced high-speed, package-type Programma­ble Controller. While the CP1H employs the same architecture as the CS/CJ
Series and provides the same I/O capacity of 40 I/O points as the CPM2A, the
CP1H is approximately ten times faster.

There are three types of CP1H CPU Units to select from: a basic CPU Unit
(X), a CPU Unit with built-in analog I/O terminals (XA), and a CPU Unit with
Dedicated Pulse I/O Terminals (Y).

Basic CPU Units: X The X CPU Units are the standard models in the CP1H Series.

• The CPU Unit has 24 inputs and 16 outputs built in.

• High-speed counters and pulse outputs can be used on four axes with the
CPU Unit alone.

• The CP1H can be expanded to a maximum total of 320 I/O points by
using CP-series Expansion I/O Units.

• Using CP-series Expansion Units also allows extra functions (such as
temperature sensor inputs) to be added.

• Installing an Option Board enables RS-232C and RS-422A/485 communi­cations for Programmable Terminals, Bar Code Readers, Inverters, etc.

• Using CJ-series CPU Bus Units enables communications with higher and
lower level devices.

High-speed Counter
Functions (All
Models)

High-speed counter inputs can be enabled by connecting rotary encoders to
the built-in inputs. The ample number of high-speed counter inputs makes it
possible to control a multi-axis device with a single PLC.

• X and XA CPU Units
Four 100-kHz (single phase)/50-kHz (differential phases) high-speed
counter inputs are provided as a standard feature. (See note.)

Note Settings in the PLC Setup determine whether each input point is to

be used as a normal input, interrupt input, quick-response input, or
high-speed counter.

• Y CPU Units
Along with two 100-kHz (single phase)/50-kHz (differential phases) high­speed counter inputs, two 1-MHz (single phase)/500-kHz (differential
phases) dedicated high-speed counter terminals are provided.

An interrupt task can be started when the count reaches a specified value or
falls within a specified range.

High-speed Counter Input Frequency (Speed) Monitoring

The input pulse frequency can be monitored using the PRV instruction (one
point only).

High-speed Counter PV Holding/Refreshing

It is possible to toggle between holding and refreshing the high-speed counter
PV by turning ON and OFF the High-speed Counter Gate Flag from the ladder
program.

Versatile Pulse
Control (All Models)

Positioning and speed control by a pulse-input servo driver is enabled by out­putting fixed duty ratio pulse output signals from the CPU Unit's built-in out­puts.

Four axes (X,Y, Z, and θ) can be controlled. A 1-MHz speed pulse rate is also
possible for Y CPU Units.

• X and XA CPU Units
Pulse outputs for 4 axes at 100 kHz maximum are provided as standard
features. (See note.) (Unit version 1.0 or earlier: Pulse outputs for 2 axes
at 100 kHz maximum and 2 axes at 30 kHz maximum.)

Note The instruction used to control each output point determines

whether it is used as a normal output, pulse output, or PWM output.

pulse output terminals for two axes at 1 MHz are provided as standard
features. (See note.)
High-speed, high-precision positioning by linear servomotor, direct drive
motor, etc., is enabled using 1-MHz pulses.

Note The instruction used to control each output point determines

whether it is used as a normal output, pulse output, or PWM output.

Full Complement of Pulse
Output Functions (All
Models)

Select CW/CCW Pulse Outputs or Pulse Plus Direction Outputs for the
Pulse Outputs

The pulse outputs can be selected to match the pulse input specifications of
the motor driver.

Easy Positioning with Absolute Coordinate System Using Automatic
Direction Setting

For operations in an absolute coordinate system (i.e., when the origin is
established or when the PV is changed by the INI instruction), the CW/CCW
direction can be automatically set when PULSE OUTPUT instructions are
executed according to whether the specified number of output pulses is more
or less than the pulse output PV.

Triangular Control

If the amount of output pulses required for acceleration and deceleration (the
target frequency times the time to reach the target frequency) exceeds the
preset target number of output pulses during positioning (when the ACC
instruction in independent mode or the PLS2 instruction is executed), the
acceleration and deceleration will be shortened and triangular control will be
executed instead of trapezoidal control. In other words, the trapezoidal pulse
output will be eliminated, with no period of constant speed.

Target Position Changes during Positioning (Multiple Start)

While positioning using a PULSE OUTPUT (PLS2) instruction is in progress,
the target position, target speed, acceleration rate, and deceleration rate can
be changed by executing another PLS2 instruction.

Positioning Changes during Speed Control (Interrupt Feeding)

While speed control in continuous mode is in effect, it is possible to change to
positioning in independent mode by executing a PULSE OUTPUT (PLS2)
instruction. By this means, interrupt feeding (moving a specified amount) can
be executed under specified conditions.

Target Speed, Acceleration Rate, and Deceleration Rate Changes during
Acceleration or Deceleration

When a PULSE OUTPUT instruction with trapezoidal acceleration and decel­eration is executed (for speed control or positioning), the target speed and
acceleration and deceleration rates can be changed during acceleration or
deceleration.

Lighting and Power Control by Outputting Variable Duty Ratio Pulses

Operations, such as lighting and power control, can be handled by outputting
variable duty ratio pulse (PWM) output signals from the CPU Unit's built-in
outputs.

Origin Searches (All
Models)

Origin Search and Origin Return Operations Using a Single Instruction

An accurate origin search combining all I/O signals (origin proximity input sig­nal, origin input signal, positioning completed signal, error counter reset out­put, etc.) can be executed with a single instruction. It is also possible to move
directly to an established origin using an origin return operation.

Input Interrupts (All
Models)

In direct mode, an interrupt task can be started when a built-in input turns ON
or OFF. In counter mode, the rising or falling edges of built-in inputs can be
counted, and an interrupt task started when the count reaches a specified
value. The maximum number of points is 8 for X and XA CPU Units and 6 for
Y CPU Units. (See note.)

Note For each input point, a selection in the PLC Setup determines whether it is to

be used as a normal input, interrupt input, quick-response input, or high­speed counter. The interrupt input response frequency in counter mode must
be 5 kHz or less total for all interrupts.

Quick-response
Inputs (All Models)

By using quick-response inputs, built-in inputs up to a minimum input signal
width of 30 µ s can be read regardless of the cycle time.

The maximum number of points is 8 for X and XA CPU Units and 6 for Y CPU
Units. (See note.)

Note For each input, a PLC Setup parameter determines whether it is to be used as

a normal input, interrupt input, quick-response input, or high-speed counter.

Analog I/O Function
(XA CPU Units Only)

XA CPU Units have analog I/O functionality, with 4 analog voltage/current
inputs and 2 analog voltage/current outputs built in.

• A wide range of applications is possible at a resolution of 6,000 or 12,000.

• Application is also possible for process-control sensor input or Inverter
control without using Expansion I/O Units.

Analog Settings (All Models)

Changing Settings Using
Analog Adjustment

By adjusting the analog adjuster with a Phillips screwdriver, the value in the
Auxiliary Area can be changed to any value between 0 and 255. This makes it
easy to change set values such as timers and counters without Programming
Devices.

Changing Settings Using
External Analog Setting
Inputs

External analog values of 0 to 10 V (resolution: 256) are converted to digital
values and stored in a word in the AR Area. This enables applications that
require on-site adjustment of settings that do not demand a particularly high
degree of accuracy, such as for example, a setting based on changes in out­door temperatures or potentiometer inputs.

Features and Main Functions Section 1-1

Note (1) The Modbus-RTU easy master (available for all models) makes it easy to

control Modbus Slaves (such as Inverters) with serial communications.
After the Modbus Slave address, function, and data have been preset in
a fixed memory area (DM), messages can be sent or received indepen­dently of the program by turning software switches.

(2) By using the serial PLC Links (available for all models), a maximum of 10

words of data per CPU Unit can be shared independently of the program
among a maximum of nine CPU Units (CP1H-CP1H-CJ1M) using RS­422A/485 Option Boards.

7-segment LED
Display (All Models)

A two-digit 7-segment LED display makes it easy to monitor PLC status.
This improves the human-machine interface for maintenance, making it easier

to detect troubles that may occur during machine operation.

• Displays error codes and details for errors detected by the CPU Unit.

Modbus-RTU

Communications can be executed independently of
the program by setting a Modbus-RTU command in
the DM and turning ON a software switch.

Features and Main Functions Section 1-1

• Displays the progress of transfers between the CPU Unit and Memory
Cassette.

• Displays changes in values when using the analog control.

• Displays user-defined codes from special display instructions in the lad­der program.

No-battery Operation
(All Models)

Programs, the PLC Setup, and other data can be automatically saved to the
CPU Unit's built-in flash memory. Moreover, DM Area data can be saved to
the flash memory and then used as initial data when the power is turned ON.

This allows programs and initial values (such as recipe setup data) in the DM
Area to be saved in the CPU Unit without the need to maintain a backup bat­tery.

Memory Cassettes
(All Models)

Built-in flash memory data, such as programs and DM initial-value data, can
be stored on a Memory Cassette (optional) as backup data. In addition, pro­grams and initial-value data can be easily copied to another CPU Unit using
the Memory Cassette to recreate the same system.

Security (All Models) A password registration function is provided for the CPU Unit to prevent unau-

thorized copy of ladder programs. If an attempt is made to read a ladder pro­gram from a CX-Programmer, access to the program is denied if the password
that is entered does not match the registered password. If incorrect pass­words are entered for five consecutive attempts, the CPU Unit does not
accept any more passwords for two hours.

System Configuration Section 1-2

1-2-4 Restrictions on System Configuration

The following restrictions apply to the CP-series Expansion Units, CP-series
Expansion I/O Units, and CJ-series Units that can be connected to CP1H
CPU Units.

■ Number of Expansion Units and Expansion I/O Units Connected

A maximum of seven Units can be connected. If eight or more Units are con­nected, an I/O UNIT OVER error will occur and the PLC will not operate.

■ Number of Words Allocated

The total number of either input or output words allocated to Expansion Units
and Expansion I/O Units must be no more than 15. Even if no more than
seven Units are connected, an I/O UNIT OVER error will be generated if 16 or
more input or output words are allocated.

■ Current Consumption

The total combined current consumption of the CP1H CPU Unit, Expansion
Units, Expansion I/O Units, and CJ-series Units must be no more than 2 A for
5 V and 1 A for 24 V and the total power consumption must be no more than
30 W. For CPU Units with AC power supply, the current consumption from
external 24-VDC power supply output must be included.

■ Number of CJ-series Units Connected

No more than two CJ-series Special I/O Units or CPU Bus Units can be con­nected to the CP1H via a CJ Unit Adapter. No CJ-series Basic I/O Units can
be connected.

Example: Calculating the Limit on the Number of Connected Units

In this example, because each CPM1A-TS002 Temperature Sensor Unit is
allocated four input words, no more than three of these Units can be con­nected. (Three Units × four words = 12 words.) After these have been con­nected, there remain unallocated three input words and 15 output words. The
following table provides an example of Units that can be mounted in combina­tion without exceeding these limits.

Combination Example

■ Restrictions on the number of simultaneously ON output points

CP1W-32ER/32ET/32ET1’s maximum number of simultaneously ON points is

■ Restrictions for the Ambient Temperature

Restrictions in the System Configuration

Configure the system within the restrictions for the output load current, simul­taneously ON inputs, and total power consumption.

Power Supply Voltage Specifications for CPU Units with DC Power and
Transistor Outputs

When connecting CP-series Expansion I/O Units with Relay Outputs to CPU
Units with DC Power and Transistor Outputs (CP1H-X40DT(1)-D, CP1H­XA40DT(1)-D, and CP1H-Y40DT(1)-D), use a power supply voltage of
24 VDC ±10% if connecting more than three Expansion I/O Units or if the
ambient temperature is greater than 45°C.

Mounting Restriction

When connecting CP-series Expansion Units or Expansion I/O Units, provide
a space of approximately 10 mm between the CPU Unit and the first Expan­sion Unit or Expansion I/O Unit.

If sufficient space cannot be provided between the CPU Unit and the first
Expansion Unit or Expansion I/O Unit, reduce the temperatures in the above
derating curves for the output load current, number of simultaneously ON
inputs, and total power consumption by 5°C.

Features CPU Unit setting method

Peripheral bus
(toolbus)

This is the faster mode, so it is
generally used for CX-Pro­grammer connections.

• Only 1: 1 connections are
possible.

• When a CP1H CPU Unit is
used, the baud rate is auto­matically detected by the Sup­port Software.

Turn ON pins SW4 (Serial Port

1) and SW5 (Serial Port 2) on
the DIP switch on the front
panel of the CPU Unit. These
settings enable connection by
peripheral bus regardless of the
serial port settings in the PLC
Setup.

Host Link
(SYSWAY)

A standard protocol for host
computers with either 1: 1 or 1:
N connections.

• Slower than the peripheral
bus mode.

• Allows modem or optical
adapter connections, or long­distance or 1: N connections
using RS-422A/485.

Turn OFF pins SW4 (Serial Port

1) and SW5 (Serial Port 2) on
the DIP switch on the front
panel of the CPU Unit.

The mode will then be deter­mined by the serial port set­tings in the PLC Setup. The
default settings are for Host
Link with a baud rate of 9,600
bits/s, 1 start bit, data length of
7 bits, even parity, and 2 stop
bits.

Function Blocks Section 1-5

1-5 Function Blocks

In the SYSMAC CP Series, function blocks can be used in programming just
as in the CS/CJ Series.

1-5-1 Overview of Function Blocks

A function block is a basic program element containing a standard processing
function that has been defined in advance. Once the function block has been
defined, the user just has to insert the function block in the program and set
the I/O in order to use the function.

As a standard processing function, a function block is not created with actual
physical addresses, but local variables. The user sets parameters (addresses
or values) in those variables to use the function block. The addresses used for
the variables themselves are automatically assigned by the system (CX-Pro­grammer) each time they are placed in the program.

In particular, each function block is saved by the CX-Programmer as an indi­vidual file that can be reused with programs for other PLCs. This makes it pos­sible to create a library of standard processing functions.

1-5-2 Advantages of Function Blocks

Function blocks allow complex programming units to be reused easily. Once
standard program sections have been created as function blocks and saved in
files, they can be reused just by placing a function block in a program and set­ting the parameters for the function block's I/O. Reusing standardized function
blocks reduces the time required for programming/debugging, reduces coding
errors, and makes programs easier to understand.

Structured
Programming

Structured programs created with function blocks have better design quality
and required less development time.

Function Blocks Section 1-5

Easy-to-read “Block Box”
Design

The I/O operands are displayed as local variable names in the program, so
the program is like a “black box” when entering or reading the program and no
extra time is wasted trying to understand the internal algorithm.

Different Processes Easily
Created from a Single
Function Block

Many different processes can be created easily from a single function block by
using input variables for the parameters (such as timer SVs, control con­stants, speed settings, and travel distances) in the standard process.

Reduced Coding Errors Coding mistakes can be reduced, because blocks that have already been

debugged can be reused.

Data Protection The local variables in the function block cannot be accessed directly from the

outside, so the data can be protected. (Data cannot be changed unintention­ally.)

Improved Reusability
through Programming
with Variables

The function block's I/O is entered as local variables, so the data addresses in
the function block do not have to be changed as they do when copying and
reusing a program section.

Creating Libraries Processes that are independent and reusable (such as processes for individ-

ual steps, machinery, equipment, or control systems) can be saved as func­tion block definitions and converted to library functions.

The function blocks are created with local variable names that are not tied to
physical addresses, so new programs can be developed easily just by reading
the definitions from the file and placing them in a new program.

Nesting Multiple
Languages

Mathematical expressions can be entered in structured text (ST) language.
Nesting function blocks is supported for CX-Programmer Ver. 6.0 or higher.

For example, it is possible to express only special operations in ST language
within a function block in a ladder diagram.

For details on using function blocks, refer to the CX-Programmer Ver. 7.0
Operation Manual: Function Blocks (Cat. No. W447).

Specifications Section 2-2

Note The above values are for a cold start at room temperature for an AC power

supply, and for a cold start for a DC power supply.

• A thermistor (with low-temperature current suppression characteristics) is
used in the inrush current control circuitry for the AC power supply. The
thermistor will not be sufficiently cooled if the ambient temperature is high
or if a hot start is performed when the power supply has been OFF for
only a short time, so in those cases the inrush current values may be
higher (as much as two times higher) than those shown above.

• A capacitor delay circuit is used in the inrush current control circuitry for
the DC power supply. The capacitor will not be charged if a hot start is
performed when the power supply has been OFF for only a short time, so
in those cases the inrush current values may be higher (as much as two
times higher) than those shown above.

• Always allow for this when selecting fuses and breakers for external cir­cuits.

Interrupt Inputs and
Quick-response Inputs

Input bits CIO 0.00 to CIO 0.03 and CIO 1.00 to CIO 1.03 can be used not
only as normal inputs but also as interrupt or quick-response inputs depend­ing on the settings in the PLC Setup.

The ON/OFF response time is 8 ms for normal inputs, but it can be changed
in the PLC Setup to 0, 0.5, 1, 2, 4, 8, 16, or 32 ms.

Analog I/O Specifications

Note (1) The built-in analog input switch is used for toggling between voltage input

and current input. (The default setting at the time of shipping is for voltage
input.)

(2) Switching between 1/6,000 and 1/12,000 resolution is done in the PLC

Setup. The same resolution setting is used for all I/O words. It is not pos­sible to set them individually.

(3) The total conversion time is the total of the conversion times for all the

points that are used. It would be 6 ms for 4 analog inputs and 2 analog
outputs.

(4) When the analog current output is within 0 to 20 mA, the accuracy cannot

be ensured if below 0.2 mA.
