About this Manual:

This manual descr ibes installation and operat ion of the CP-series Program mable Controllers (PLCs)
and includes the sections described below. The CP Series p rovid es 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 opera te a CP-series P LC. 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 Uni ts and CPU Bus Unit s of the CJ Ser ies ca n thus be
used. CJ-series Basic I/O Units, however, cannot be used. Always use CPM1A Expansion Un its and
CPM1A 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.

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 te r minals o r ter minal blocks while the power is bein g

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), includin g the following items, to ensure safety in the system if an
abnormality occurs due to malfunc tion of the PLC or anoth er external factor
affecting the PLC operation. Not doing so may result in serious accidents.

xxii

• Emergency stop cir cuits, inter lock circui ts, limit cir cuits, and sim ilar safety
measures must be provided in external control circuits.

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 counterme asure 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 destruc tio n of th e ou tpu t transis to rs. As a c ou nter­measure for such problems, extern al safety measures must be provide d
to ensure safety in the system.

• When the 24-V DC output (service power supply to the PLC) is over­loaded or shor t-circuited, the voltage may drop and result in the out puts
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 in terruptions, or other causes. Not doing so may result in
serious accidents.

!Caution Execute online edit only after confirming that no adverse effects will be

caused by extending the cycle time. Other wise, 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 thes e withou t confir m ing
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 s crews may result in burning o r malfunc­tion.

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

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

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

wrong connection may cause malfunction of the system.

!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 sid e of the exter nal power suppl y, as shown in t he following

Operating Environment Precautions 4

!Caution After programming (or repr ogrammi ng) using the IOWR instruction, confir m

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 memor y when these are written to the CPU Unit. I/O memory
(including the DM Area , counter present values and Completion Flags, an d
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 ba ttery. If there is a batter y error, the contents of these
areas may not be accurate af ter a power interruption. If the con tents 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 su fficient counterm easures when installing sys tems in

the following locations:

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

• Locations subject to strong electromagnetic fields.

• Locations subject to possible exposure to radioactivity.

• Locations close to power supplies.

!Caution The operating environment of th e PLC S ystem c an have a large effect on th e

longevity and reliability of the sy stem. Improper operating environme nts 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 installati on and remains within the specifi ed conditions during the
life of the system.

Application Precautions 5

• Be sure that the ter minal 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 suppl y. Incorrect wir ing 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 o n
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 A reas required for
resuming operation. Not doing so may result in an unexpected operation.

• Confirm that no ad verse effect will occur in the system before attemptin g
any of the following. Not doing so may result in an unexpected operation.

• Changing the operating mode of the PLC ( includi ng the se tting of th e
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 p arts, be sure to confi rm that the rating of a new par t is
correct. Not doing so may result in malfunction or burning.

• Before touching the Unit, be su re to firs t to uc h a grounde d m etal li c obj ec t
in order to discharge a ny static buildup. Not doing so may result in mal­function or damage.

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

• Do not turn O FF the power supply to the Uni t while data is being tran s­ferred.

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

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

• Double-check the pin numbers when assembling an d wiring t he connec­tors.

• Wire correctly according to specified procedures.

• Do not connect pin 6 (+5V) on the RS-232C Opti on 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 conne cting cables specified in this manual to connect
the Units. Using commerc ially avai lable RS-232C computer cables may
cause failures in external devices or the CPU Unit.

xxvi

Application Precautions 5

• Check that data link tables an d parameters are p roperly set before star t­ing operation. Not doing so may result in un expe cted 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 param eter a r ea data i n th e C PU Uni t i s backed up
in the built-in flash memory. The BKUP indicator will light on the fr ont of
the CPU Unit when the backup operation i s in progress. Do not tur n 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. Doin g so may cor rupt 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 batter y, supply power to the CPU Unit for at least 5
minutes and then complete battery repla cement within 5 minutes of tu rn
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, Spec ia l I/O
Units, and CPU Bus Units: AWG22 to AWG18 (0.32 to 0.82 mm

• UL standards required that batteries be replaced only by experienced
technicians. Do not allow unqualified pe rsons 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 s ubject the
battery to str ong shocks or defor m the barr y by apply ing pressu re. Doing
any of these may result in leakage, ruptur e, heat gene ration, or ig nit ion of
the battery. Dispose of any battery that has been dropped on the f loor 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 turne d
ON before the power to the control system is turned ON. If the PLC power
supply is turned ON afte r the c ontrol power su pply, temporary errors may
result in control system signals bec ause the outpu t ter minals on DC Out­put Units and other U nits will mo mentar ily tur n ON when power is tur ned
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.

• 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 conditi ons when this
occurs. (When operation stops for a fatal error, including those produced
with the FALS(007) instruction, all outputs from Outpu t Unit will be turned
OFF and only the internal output status will be maintained.)

6-1 Applicable Directives

•EMC Directives

• Low Voltage Directive

6-2 Concepts

EMC Directives

OMRON devices that comply with EC Directives also conform to the r elated
EMC standards so tha t they can be more e as ily built in to ot her d evices or th e
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 custo mer, however, must be che cked by
the customer.

EMC-related perfor ma nce o f th e O M RON devices that c omp ly wi th EC Di re c­tives will vary depending on the configuration, wi ring, and oth er conditions of
the equipment or control panel on which the OMRON devices are installed .
The customer must, therefore, perform the fina l check to conf ir m th at 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 voltage s of 50 to 1,00 0 V AC and 75
to 1,500 V DC meet the required safety standards for the PLC (EN61131-2).

6-3 Conformance to EC Directives

The CP1H PLCs comply with E C Directives. To ensure that the machine or
device in which the CP1H PLC is us ed complies with EC Direc tives, 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 Directive s 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.

Conformance to EC Directives 6

6-4 Relay Output Noise Reduction Methods

The CP1H PLCs conforms to the Commo n Emissi on Stand ards (EN61131- 2)
of the EMC Directives. However, noise generated by relay output switching
may not satisfy these Standards. In such a ca se, a noise filter must be con­nected to the load side o r other appropriate counter measures must be pro­vided external to the PLC.

Countermeasures taken to satisfy the standards vary depending on the
devices on the load side, wiring, co nfi guration of mac hi nes, etc . Following are
examples of countermeasures for reducing the generated noise.

Countermeasures

Countermeasur es are not required if the f requency 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.

Countermeasure Examples

When switching an inductive load, co nne ct a n su r ge pr ot ec tor, diodes, etc., in
parallel with the load or contact as shown below.

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 c apacitor 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 v oltag e of 1V.
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 30 0 V. If the circ uit i s an
AC circuit, use a capacitor with no
polarity.

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.

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.

The SYSMAC CP1H is a n 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 typ es of CP1H CPU Units to select from: a basi c 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).

High-speed Processing for High-speed Counter Present Value (PV)
Target Values or Range Comparison Interrupts

An interrupt ta sk can be star te d when the count r eaches a s pecified value or
falls within a specified range.

High-speed Counter Input Frequency (Speed) Monitoring

The input pulse fr equency can be moni tored using the PRV instruc tion (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.

Positioning and speed control by a pulse-in put servo driver is enabled by out­putting fixed duty ratio p ulse output signals fr om the CPU Unit's built-in o ut­puts.

Four axes (X,Y, Z, and

θ) can be controlled. A 1 -M Hz s pee d pu ls e rate i s als o

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

The pulse outputs ca n be selected to m atch the pulse in put specification s 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 ch anged by the INI instruc tion), the CW/CCW
direction can be automatically set when PULSE OUTPUT instructions are
executed according to whether the specifie d numbe r of output pulses i s more
or less than the pulse output PV.

Triangular Control

If the amount of output puls es required for acce leration and deceleration (th e
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 d eceleration will be s hor tened and trian gular control w ill be
executed instead of trapezoidal control. In other words, the trapezoida l pulse
output will be eliminated, with no period of constant speed.

Target Position Changes during Positioning (Multiple Start)

While positioning using a PUL SE OUTPU T (PLS2) ins tructio n is in progre ss,
the target position, targe t speed, accelerati on 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, int errupt feedin g (moving a spe cified am ount) ca n
be executed under specified conditions.

Features and Main Functions Section 1-1

T ar get Speed, Acceleration Rate, and Deceleration Rat e Changes during
Acceleration or Deceleration

When a PULSE OUTPU T instr uct ion with trapezoidal acc elerat ion and de cel­eration 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 con trol, can be handl ed by outputting
variable duty ratio pulse (PWM) output signals from the CPU Unit's built-in
outputs.

An accurate origi n s ear c h co mb ini ng all I/O si gnals (origin pr oximity input sig­nal, origin input sign al, positioning compl eted signal, error counte r reset out­put, etc.) can be executed with a sin gl e ins truction. It is also pos s ible to move
directly to an established origin using an origin return operation.

In direct mode, an interrupt task can be started when a built-in input tur ns ON
or OFF. In counter m ode, 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 i s 8 for X and XA CPU Unit s and 6 for

External analo g 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

Programs, the PLC Setup, and other data can be aut omatically saved to the
CPU Unit's built-in flash memor y. 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 initi al values (such a s recip e se tup data ) in the D M
Area to be saved in the CPU Unit without the need to maintain a backup bat­tery.

The following restrictions apply to the CPM1A Expansion Units, CPM1A
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 ar e 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.

CJ-series Units

■ 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 th an 2 A for
5 V and 1 A for 24 V and the total power consumption must be no more tha n
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 CP U Bus Units can be con­nected to the CP1H v ia a CJ Unit Adapter. No CJ-serie s 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 con-

nected, there remain una ll ocated thr ee inp ut wor ds and 15 output words. The
following table provides an example of Units that can be mounted in combina­tion without exceeding these limits.

Restrictions when
Connecting by USB

In conformity with USB specifications, the following restrictions apply when
connecting a computer running Support Software.

• A USB connection is po ssible for only one CP1 H from a sin gle co mputer.
It is not possible to connect multiple CP1Hs simultaneously.

• Do not disconnect the USB cable while the Support Software is con­nected online. Before disconnecti ng the USB cable, be sure to plac e the
application in offline status. If the USB cable is disconnected while online,
the situations described below will occur as a result of OS error.

• Windows Me, 2000, or XP:
The Support Software cannot be returned to online status by simply re­connecting the USB cable. First return the Support Software to offline
status, and then reconnect th e USB cable. Then perform the online
connection procedure for the Support Software.

• Windows 98:
If the USB cable is disconnec ted while on line, an er ror mes sage may
be displayed on a blue screen. If that occurs, it will be necessary to re­boot the computer.

1-3-2 Connecting to a Serial Port

Mounting a CP1W-CIF01 RS-232C Option Board in a CP1H Option Board

Function Blocks Section 1-5

1-5 Function Blocks

In the SYSMAC CP Series, fun ction blocks can be used in p rogramming 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 d efined in advance. Once the function block has been
defined, the user j ust has to in sert the function block in the program and set
the I/O in order to use the function.

As a standard processin g function , a functio n block is not created with actual
physical addresses, but local var ia bles. The use r se ts p aram eter s (addresses
or values) in those variables to use the function block. The addresses used for
the variables themselves are automati cally assigned by the sys tem (CX-Pro­grammer) each time they are placed in the program.

In part icular, each function block is s aved 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. Onc e
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 pro grams created with function blocks have better design quality
and required less development time.

Improved Reusability
through Programming
with Variables

The I/O operands are disp layed a s 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.

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.

debugged can be reused.

outside, so the data can be pro tected. (Data cann ot be changed uni ntention­ally.)

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

Creating Libraries Process es that are inde pendent and r eusable (such as pro cesses for individ-

ual steps, machiner y, equipmen t, or control systems) c an be saved as func­tion block definitions and converted to library functions.

The function blocks are created with loca l 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 suppor ted for CX-Programmer Ver. 6.0 or higher.

For example, it is possible to express only special op erations i n ST lang uage
within a function block in a ladder diagram.

• A thermistor (w ith low-tem peratur e c urr ent s up pr essi on ch a racteristics) is
used in the inr ush current contro l 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 perfor med 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 fu ses and breakers for external cir­cuits.

• A capacitor delay circui t is used in the inr ush current co ntrol circuitr y for
the DC power supply. T he capacitor will not be char ged if a hot start is
performed when the power supply has been OFF for only a short time, so
in those cases the inr ush current values may be higher (as much as two
times higher) than those shown above.
