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 and CP1L CPU Units and is designed with the same
basic architecture as the CS and CJ Series. 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.

!WARNING It is extremely important that a PLC and all PLC Units be used for the speci-

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.

!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.

!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.

Operating Environment Precautions 4

!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 CP1L 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.

• Locations subject to possible exposure to radioactivity.

• Locations close to power supplies.

!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.

Application Precautions 5

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.

• 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.

xxviii

Application Precautions 5

• 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 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 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 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 (CP1W-CIF01)
on the CPU Unit to any external device other than the NT-AL001 or
CP1W-CIF11 Conversion Adapter. The external device and the CPU Unit
may be damaged.

xxix

Application Precautions 5

• 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.

• 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 written. Doing so may corrupt the data in the Memory Cassette.
The BKUP indicator will light while the Memory Cassette is being written.
Wait for the BKUP indicator 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 terminals:
AWG22 to AWG18 (0.32 to 0.82 mm

2

).

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

• 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.

• 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.)

Conformance to EC Directives 6

6 Conformance to EC Directives

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 related
EMC standards so that they can be more easily built into other devices or the
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).

6-3 Conformance to EC Directives

The CP1L PLCs comply with EC Directives. To ensure that the machine or
device in which the CP1L PLC is used complies with EC Directives, the PLC
must be installed as follows:

1,2,3... 1. The CP1L 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. CP1L 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 CP1L 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.

xxxi

Conformance to EC Directives 6

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.

Countermeasure Examples

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

1-1-2 Features

This section describes the main features of the CP1L.

Basic CP1L Configuration

Positioning with an
Inverter

Positioning can be controlled using an inverter. Previous a internal pulse out­put with trapezoidal acceleration/deceleration is created using the PULSE
OUTPUT instruction. The position offset is calculated using an error counter
for the feedback pulse input from a rotary encoder connected to an inductive
motor and the internal pulse output. The error counter is then used to output a
speed command to the inverter to control positioning. This enables positioning
with high-capacity motors, as well as low-cost positioning with small-capacity
motors (in comparison to using a servo).

Features and Main Functions Section 1-1

Note If high-precision positioning is required, we recommend using an inverter with

vector control.

Full Complement of
High-speed Counter
Functions

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.

• Four 100-kHz (single phase)/50-kHz (differential phases) high-speed
counter inputs (4 counters/2 axes) 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.

A virtual pulse output is created using a pulse output instruction, the position
offset is calculated using an error counter, and a frequency (i.e., speed)
command is output according to the position offset to control positioning.

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

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 (counter 0) only, and you must select whether to use input frequency
monitoring or counter 3; you cannot use both).

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 (CPU Units
with Transistor
Outputs Only)

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.

• Pulse outputs for 2 axes at 100 kHz maximum are provided as standard
features. (See note.)

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

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.

16 built-in outputs
(Functions assigned.)

2 pulse outputs

Features and Main Functions Section 1-1

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 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 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 interrupt input points is 6 for CPU Units with
20, 30, or 40 I/O points and 4 for CPU Units with 14 I/O points.

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

By using quick-response inputs, built-in inputs up to a minimum input signal
width of 50

µs can be read regardless of the cycle time. The maximum num-

ber of quick-response input points is 6 for CPU Units with 20, 30, or 40 I/O
points and 4 for CPU Units with 14 I/O points.

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.

Features and Main Functions Section 1-1

Analog Settings

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.

Example: The production quantity could be changed by

Connectability with Various Components

USB Port for
Programming Devices

CX-One Support Software, such as the CX-Programmer, connects from the
USB port on a computer to the CP1L built-in peripheral USB port via commer­cially available USB cable.

Expansion Capability for
Serial Ports

Up to two Serial Communications Boards each with one RS-232C port or one
RS-422A/485 port can be added to a CPU Unit with 30 or 40 I/O points. One
Serial Communications Boards can be added to a CPU Unit with 20 or 14 I/O
points. With a total of up to three ports, including the USB port, this makes it
possible to simultaneously connect a computer, PT, CP1L, and/or various
components, such as an Inverter, Temperature Controller, or Smart Sensor.

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, a maximum of 10 words of data per CPU

Unit can be shared independently of the program among a maximum of
nine CPU Units (CP1L-CP1L-CP1H/CJ1M) using RS-422A/485 Option
Boards.

No-battery Operation 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.

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 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.

Function Blocks Section 1-5

1-5 Function Blocks

Function blocks can be used in programming SYSMAC CP-series PLCs.

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.

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.

Function Blocks Section 1-5

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 (1) The above values are for a cold start at room temperature for an AC pow-

er 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.

(2) Use the external power supply to power input devices. Do not use it to

drive output devices.

(3) This is the rated value for the maximum system configuration. Use the fol-

lowing formula to calculate DC power consumption for CPU Units with DC
power.

Formula:
DC-powered CP1L power consumption = 5-V current consumption

× 5 V/

70% (CP1L internal power efficiency) + 24-V current consumption

× 1.1

(current fluctuation factor)
Calculation Example

CP1L Power Consumption

= (0.39 A

× 5 V/70% + 0.139 A × 24 V) × 1.1

= 6.73 W

The above calculation results show that a power supply with a capacity of
7 W or greater is required.

Note (1) The current consumption of the CP1W-ME05M Memory Cassette and

CP1W-CIF01/11 Option Boards are included in the current consumption

of the CPU Unit.
(2) CPU Units with DC power do not provide an external power supply.
(3) The current consumptions given in the following table must be added to

the current consumption of the CPU Unit if an Expansion Unit or Expan-

sion I/O Unit is connected.

the flash memory. It is also possible to save and read data memory initial data.

The data is automatically transferred to RAM when the power supply is turned ON.

(Data memory initial data, however, may or may not be transferred, depending on

the selection in the PLC Setup.

Battery backup The HR Area, DM Area, and counter values (flags, PV) are backed up by a battery.

Battery model: CJ1W-BAT01 (Built into the CP1L CPU Unit.)

Maximum battery service life: 5 years

Guaranteed (ambient temperature: 55°C): 13,000 hours (approx. 1.5 years)

Effective value (ambient temperature: 25°C): 43,000 hours (approx. 5 years)
Memory Cassette function A CP1W-ME05M Memory Cassette (512K words, optional) can be mounted. It can

be used to back up the following data on the CPU Unit's RAM and to transfer the

data at startup.

• Data saved on Memory Cassette: User programs, parameters (such as the PLC
Setup), DM Area, data memory initial data, comment memory (CX-Programmer
conversion tables, comments, program indices), and FB program memory.

• Writing to Memory Cassette: By operations from the CX-Programmer.

• Reading from Memory Cassette: At startup, or by operations from the CX-Program­mer.

CP1L CPU Unit Operation Section 2-3

2-3 CP1L CPU Unit Operation

2-3-1 Overview of CPU Unit Configuration

The CP1L CPU Unit memory consists of the following blocks.

(1) • Data is backed up from RAM to the built-in flash memory when

changes are made, e.g., from the CX-Programmer.

• When the power supply is turned ON, data is transferred from the built­in flash memory to RAM.

(2) • A CX-Programmer operation can be used to transfer DM Area initial

values from RAM to the built-in flash memory.

• The PLC Setup can be set so that DM Area initial values are trans­ferred from the built-in flash memory to RAM when the power supply
is turned ON.

(3) • CX-Programmer operations can be used to transfer data from RAM to

the Memory Cassette or from the built-in flash memory to the Memory
Cassette.

CP1L CPU Unit Operation Section 2-3

• When the power supply is turned ON, data is transferred from the
Memory Cassette to the built-in flash memory and RAM. Data can also
be transferred from the Memory Cassette to the built-in flash memory
and RAM using the CX-Programmer.

User Program The user program consists of up to 288 tasks, including interrupt tasks. Each

task is programmed from the CX-Programmer and then transferred to the
CPU Unit.

There are two types of tasks: cyclic tasks and interrupt tasks. Cyclic tasks are
executed once each cycle and interrupt tasks are executed only when the
interrupt conditions are met. There can be up to 32 cyclic tasks and up to 256
interrupt tasks. Cyclic tasks are executed in the order of the task numbers.

Instructions programmed in the tasks are executed in order from the first
instruction and then I/O memory is refreshed. When all cyclic tasks have been
executed, I/O refreshing with PLC Units is performed and then the cyclic tasks
are executed again starting from the one with the lowest task number. This is
called the cyclic scan method.

I/O Memory The I/O memory area is a RAM area read and written by the user. Some parts

of the I/O memory are cleared when the power is interrupted. Other parts are
maintained. There are parts that used for data exchange with PLC Units and
parts that are used internally.

There are two ways to refresh the parts of I/O memory used for data
exchange with PLC Units: Once each program execution cycle and immedi­ately when needed when executing specific instructions.

Parameter Area In addition to the I/O memory used as instructions operands by the user, there

is also a separate memory area that can be manipulated only from the CX­Programmer. This area, called the parameter area, contains the following.

• PLC Setup

• Routing tables

PLC Setup The PLC Setup contains configuration parameters that can be set by the user

to define the basic specifications of the CPU Unit. Included are serial port set­tings, a minimum cycle time setting, and other parameters. For details, refer to
the CX-Programmer Operation Manual.

65

CP1L CPU Unit Operation Section 2-3

Routing Tables Tables specifying the communications paths from the Communications Units

on the local PLC to remote PLCs connected on other networks must be regis­tered in all the CPU Units in network PLCs to send and receive data between
networks. These tables are called the routing tables. The routing tables con­sist of the relay network table and local network table.

Routing tables are created from the CX-Programmer or Support Software for
Communications Units (e.g., CX-Integrator) and then transferred to each CPU
Unit.

Remote Network Table

The remote network tables lists the node number and network address of the
first relay node that must be passed through to reach any remote network to
which the PLC is not directly connected. Once the routing tables have been
registered, any remote network can be reached by passing through relay
nodes.

Local Network Table

The local network table contains the unit number and network address of all
Communications Units that are part of the local PLC.

Built-in Flash Memory Flash memory is built into the CP1L CPU Units. Data in the following areas is

automatically backed up to the flash memory whenever it is written in any way
other than by instructions in the user program, e.g., when the CX-Programmer
or PT is used to transfer or edit data, edit the program online, or transfer data
from a Memory Cassette.

• User program area

• Parameter area (PLC Setup and routing tables)

The next time the power supply is turned ON, the data in the built-in flash
memory is automatically transferred to user memory (i.e., the user program
area and parameter area).

It is also possible to save data from data areas in I/O memory in the built-in
flash memory using operations from the CX-Programmer.

The symbol table, comment file, and program index file can be stored in the
comment memory in flash memory. When the program is transferred from the
CX-Programmer to the CPU Unit, function block program information is also
stored automatically in flash memory.

Note The BKUP indicator on the front of the CPU Unit will light whenever the built-in

flash memory is being written or the Memory Cassette is being accessed.
