manual close at hand for reference during operation.

WARNING

It is extremely important that a PLC and all PLC Units be used for the
specified 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.

Safety Precautions

WARNING

Confirm safety sufficiently before transferring I/O memory area status from
the CX-Programmer to the PLC. The devices connected to Output Units
may malfunction, regardless of the operating mode of the CPU Unit.
Caution is required in respect to the following functions.

• Transferring from the CX-Programmer to real I/O (CIO Area) in the CPU

Unit using the PLC Memory window.

• Transferring from file memory to real I/O (CIO Area) in the CPU Unit

using the Memory Card window.

OMRON CX-Programmer – Operation Manual

CX-Programmer_Page (viii)

WARNING

Observe the following precautions when using the PLC Backup Tool.

• Sufficiently check the data that is selected for restoring before performing

the next step. If the correct data is not restored, unexpected operation
may occur in the controlled system after the data is restored.

• Some Special I/O Units and CPU Bus Units operate with parameters that

are stored in the CPU Unit. If one of these Units is selected for backup,
restrictions will be displayed in the Comments Area of the Backup from
PLC Dialog Box. Confirm the restrictions, and always select the Special
I/O Unit or CPU Bus Unit together with the CPU Unit when backing up or
restoring data. If the data from both Units is not backed up or restored
together, unexpected operation may occur in the controlled system.

• If there are any backup restrictions for the Units to which data is being

restored, the restrictions will be displayed in the Comments Area of the
Backup from PLC Dialog Box. Confirm the restrictions, and always take
the required measures. If required measures are not taken, unexpected
operation may occur in the controlled system after the data is restored.

• Forced status can be backed up, but it cannot be restored. If you

restored data that contained forced status, use the CX-Programmer after
restoring the data to force-set or force-reset bits as required. If required
bits are not force-set or force-reset, differences in the forced status in
memory may cause unexpected operation of the controlled system.

• Confirm that stopping PLC operation will not create any problems before

restoring data during PLC operation. If the PLC stops at an unanticipated
time, unexpected operation may occur in the controlled system.

• Always turn the power supply to the PLC OFF and then ON after

restoring data. If the power supply is not turned OFF and then ON,
memory in the PLC may not be updated to the restored data, which may
cause unexpected operation of the controlled system.

Caution

Observe the following precaution when specifying a symbol or word
address for an array variable index in a ladder program or when specifying
a symbol for an array variable index in an ST program.

When using a symbol or address to indirectly specify the element number
of an array variable, be sure that the resulting address is not outside the
memory area that contains the first word in the array. For example, use a
symbol comparison instruction or an IF statement to ensure that processing
is performed only when the memory area is not exceeded. If an element
number that exceeds the memory area is specified, data in another
memory area will be read or written, possibly resulting in unexpected
operation.

Caution

Observe the following precaution when specifying a symbol or word
address for an offset in a ladder program.

When using a symbol or address to indirectly specify an offset for a
memory address, be sure that the resulting address is not outside the
memory area that contains original address. For example, use a symbol
comparison instruction to ensure that processing is performed only when
the memory area is not exceeded. If the final address (i.e., the original
address plus the specified offset) exceeds the memory area, data in
another memory area will be read or written, possibly resulting in
unexpected operation.

OMRON CX-Programmer – Operation Manual

CX-Programmer_Page (ix)

Caution

Confirm safety at the destination node before transferring a program to
another node or changing contents of the I/O memory area. Doing either of
these without confirming safety may result in injury.

Caution

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

If synchronous unit operation is being used, perform online editing only
after confirming that an increased synchronous processing time will not
affect the operation of the main and slave axes.

Caution

Confirm safety sufficiently before monitoring power flow and present value
status in the Ladder Section window or when monitoring present values in
the Watch window. If force-set/reset or set/reset operations are
inadvertently performed by pressing short-cut keys, the devices connected
to Output Units may malfunction, regardless of the operating mode of the
CPU Unit.

Caution

Caution is required when connecting peripheral devices, such as a
personal computer, to the PLC when Units with non-isolated power
supplies, such as the CS1W-CLK12/CLK52(-V1), that are connected to an
external power supply are mounted to the PLC. If the 24-V side is grounded
on the external power supply, a short will be created if the 0-V side of the
peripheral device is grounded. When connecting peripheral devices, either
ground the 0-V side of the external power supply or do not ground the
external power supply at all.

Application Precaution

Observe the following precautions when using the CX-Programmer.

• Observe the following precautions before starting the CX-Programmer.

• Exit all applications not directly related to the CX-Programmer.

Particularly exit any software such as screen savers, virus checkers,
email or other communications software, and schedulers or other
applications that start up periodically or automatically.

• Disable sharing hard disks, printers, or other devices with other

computers on any network.

• With some notebook computers, the RS-232C port is allocated to a

modem or an infrared port by default. Follow the instructions in
documentation for your computer and enable using the RS-232C port
as a normal serial port.

• With some notebook computers, the default settings for saving

energy do not supply the rated power to the RS-232C port. There
may be both Windows settings for saving energy, as well as setting
for specific computer utilities and BIOS. Following the instructions in
documentation for your computer, disable all energy saving settings.

• Do not turn OFF the power supply to the PLC or disconnect the

connecting cable while the CX-Programmer is online with the PLC. The
computer may malfunction.

• With the CS/CJ-series PLCs, when creating an AUTOEXEC.IOM file

from the CX-Programmer to automatically transfer data at startup, set the
first write address to D20000 and be sure that the size of data written
does not exceed the size of the DM Area. When the data file is read from
the Memory Card at startup, data will be written in the CPU Unit starting
at D20000 even if another address was set when the AUTOEXEC.IOM
file was created. Also, if the DM Area is exceeded (which is possible
when the CX-Programmer is used), the remaining data will be written to
the EM Area. Refer to information on file operations in the CS/CJ-series
Programming Manual for details.

• Confirm that no adverse effect will occur in the system before attempting

any of the following. Not doing so may result in an unexpected operation.

Changing the operating mode of the PLC.

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

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

• Check the user program for proper execution before actually running it

on the Unit. Not checking the program may result in an unexpected
operation.

• Precaution on Using Indirect DM and EM Addresses in Comparison

Instructions:
When indirect DM or EM addresses are used as operands in comparison
instructions, the top portion of the comparison instruction will be displayed
in yellow when it is being monitored. At that time the power flow will not be
monitored to the right of such comparison instructions. The contact and
coil status, and present values of operands in special instructions will be
displayed normally.

OMRON CX-Programmer – Operation Manual

CX-Programmer_Page (xi)

• The user program and parameter area data in CS1-H CPU Units 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.
To display the status of writing to flash memory on the CX-Programmer,
place a checkmark by Display dialog to show PLC Memory Backup

Status on the PLC properties and then select Windows | PLC Memory
Backup Status from the Windows menu.

• Precaution in Changing the PLC Type

On the CX-Programmer, you can change the PLC (device) type or CPU
type. When these are changed, however, only the data for the ladder
program and the symbol tables are changed. The following data will be
initialized and must be reset.

• PLC Setup

• Expansion instructions

• I/O tables

• PLC memory

Particularly the PLC Setup has a large impact on PLC system operation.
Be careful to reset all require settings after changing the PLC type.
If expansion instruction allocations are not reset, program errors could
occur, preventing the PLC from running. Always restore the expansion
instruction allocates to the previous settings after changing the PLC
type.

OMRON CX-Programmer – Operation Manual

CX-Programmer_Page (xii)

Observe the following precautions when using the CX-Net.

• Do not change the operating mode of the CPU Unit without first

confirming that operation of the controlled system will not be affect.

• Do not run the user program on the PLC until its operation has been

checked sufficiently.

• The data link mode (manual setting or automatic setting) and data link

method are determined according to the data link setting in the startup
node. In the startup node, set a data link table in the case of manual
setting and data link automatic setting parameters in the case of
automatic setting. If the settings are incorrect, the data link will not start.

• Check the following items before starting data links. If incorrect data link

tables or parameters are set, injury may result due to unexpected
operation of the system. Even if the correct data link tables and
parameters have been set, do not start or stop data links before verifying
that there will be no adverse influence on the system.

(1) Manually Set Data Links

Check the data link tables in each node participating in the data link to
see that they are correct.

Be sure that data link tables are deleted from nodes that are not
participating in the data links.

(2) Automatically Set Data Links

Be sure that the correct DM parameters have been set in the data link
startup node.

• CPU Bus Units will be automatically restarted when routing tables are

transferred from a Programming Device to the CPU Unit. Resetting is
required to use the new tables. Confirm that restarting the CPU Bus
Units will not adversely affect system operation before transferring
routing tables.

• When Special I/O Unit or CPU Unit settings are performed in the I/O

Table Window and then transferred from the PLC Memory Window, the
following warning will be displayed if the allocated DM Area/CIO Area
addresses set for Special I/O Units or CPU Bus Units in the I/O Table
Window on the computer overlap with the PLC data table addresses.

Unless the CPU Bus Unit or Special I/O Unit settings have been

previously transferred to the CPU Unit and the allocated DM Area/CIO
Area data in the PLC data table for Special I/O Units or CPU Bus Units is
to be overwritten, always click the No Button, shift the address, and
repeat the transfer procedure.

• CPU Bus Unit and Special I/O Unit settings are not checked for logical

consistency. Be very careful of the logical consisting of the overall
settings when making any setting that affects other settings, e.g., settings
that enable or disable other settings. Transfer the Special I/O Unit or
CPU Bus Unit settings to the PLC and then start operation, being aware
that any logical inconsistencies may produce unexpected operation.

• For example, if one setting selects either user settings or default settings

and is set to use the default settings, it will not automatically change to
enable user settings even if the related user settings are made. To use
the user settings, they will have to be enabled manually and specifically
in the setting that selects either user settings or default settings.

• Support for Array Variables in Ladder, ST, and SFC Programs

Previous version (version 7.0) New version (version 7.2)

Array variables could be used for internal
variables and input-output variables in a
function block’s algorithm, but array variables
could not be used in programs (tasks).

Array variables can be specified even in programs (tasks) written in
ladder, ST, or SFC language.
This feature allows multiple variables with the same data
characteristics to be managed as a group.

• Comparing Function Block Definitions

Previous version (version 7.0) New version (version 7.2)

Function block definitions could not be
compared.

Function block definitions can be compared in detail.
This feature makes it easy to check for differences between the
programs in function block definitions.

• Comparison of Function Block Definitions, ST Programs, and Action Programs/Transition

Programs/Subcharts in SFC Programs

Previous version (version 7.0) New version (version 7.2)

ST programs and SFC programs could not be
compared.

ST programs and SFC programs can be compared.
ST programs in an SFC program can also be compared in detail.

 PLC-PT Integrated Simulation

The following improvements have been made to the simultaneous interactive
debugging function (integrated simulation), which debugs operation between the
CX-Programmer’s ladder program and NS-series PT touch panel test screens in
the CX-Designer

.

• Starting Integrated Simulator from the CX-Programmer

Previous version (version 7.0) New version (version 7.2)

The integrated simulator could be started from
the CX-Designer only; it could not be started
from the CX-Programmer.

The integrated simulator can be started from the CX-Programmer
(specifying a saved CX-Designer screen file).
With this feature, it is possible to easily confirm the interaction
between a ladder program being edited in the CX-Programmer and
NS-series PT touch panel test screens.

• Simulating the Occurrence of PLC Errors

Previous version (version 7.0) New version (version 7.2)

During simulation, it was not possible to
generate PLC system errors by manipulating
the corresponding Auxiliary Area flags. (The
system error flags were write-protected.)
It was necessary to create ladder programming
that generated errors using the FAL and FALS
instructions, and check operation in the
simulation.

PLC system errors can be generated during CX-Programmer ladder
program simulation by selecting Simulation - PLC Error Simulator
and writing the corresponding system error flags in the Auxiliary
Area.
With this feature, it is not necessary to create ladder programming
to generate errors. Also, it is easy to check the operation of the
ladder program and NS-series touch panel when PLC errors occur.

 Improvements to Symbol Tables

• Improved Interaction of the CX-Designer with Symbol Table Data

Previous version (version 7.0) New version (version 7.2)

Symbol tables could be copied and pasted from
the CX-Programmer to the CX-Designer, but
not the opposite direction.
Consequently, when NS-series touch panel test
screens were being edited in the CX-Designer
and I/O comments were edited in the CX­Designer symbol table, it was necessary to
write the data in Excel and transfer it to the CX­Programmer’s symbol table.

Symbol tables can be copied in pasted in both directions between
the CX-Designer and CX-Programmer.
This feature makes it easy to reflect changes to the CX-Designer’s
symbol table, such as edited I/O comments, in the CX­Programmer’s symbol table.

OMRON PART 1: CX-Programmer

CX-Programmer_Page (xii)

• Support for the STRING Data Type in Ladder Programs and ST Programs

Previous version (version 7.0) New version (version 7.2)

The STRING data type could be used only in
ST-language function blocks.

The STRING data type can be used in both ladder and ST
languages, in both task programs and function blocks.
The STRING data type supports ASCII characters between 1 and

255.

 Improved Automatic Online Connection

• Added Automatic Detection of the Computer’s Serial Port

Previous version (version 7.0) New version (version 7.2)

When automatic online connection was
performed from the computer’s serial port, it
was not necessary for the user to set the PLC
model because it was recognized automatically,
but the serial port had to be set in advance.

It is not necessary for the user to select the computer’s serial port in
advance.
When automatic online connection is performed, the software
automatically searches for computer serial ports that can be used. If
the software finds a serial port that can be used for the online
connection, the software automatically connects online from the
detected port, and the serial port setting is also changed
automatically.

 Improved Conversion of C500/C120/C**P Programs

Previous version (version 7.0) New version (version 7.2)

Programs stored in C500, C120, or C**P-series
PLCs could be uploaded and converted for use
in CS/CJ/CP-series PLCs or CVM1/CV-series
PLCs, but the DM and HR Area data could not
be converted to PLC memory.

DM and HR Area data can also be converted to PLC memory.
After conversion, it is now possible to select the CP1L as the PLC
model.

A backup program and I/O memory (DM and
HR Area data) file (extension .c5b) could be
used to restore the program to a
C500/C120/C**P-series PLC, but it could not be
converted to a CX-Programmer project.

A backup program and I/O memory (DM and HR Area data) file
(extension .c5b) can be converted to a CX-Programmer project for
a CS/CJ/CP-series PLC or CVM1/CV-series PLC.

A program uploaded from a C500, C120, or
C**P-series PLC could not be saved to a file in
mnemonic-text format.

A program uploaded from a C500, C120, or C**P-series PLC can
be saved to a file in mnemonic-text format. The saved file can be
pasted as text in the CX-Programmer’s Statement List (mnemonic
window), and displayed or printed in ladder format.
This feature allows the program to be checked in the CX­Programmer before converting it to a CS/CJ/CP-series PLC or
CVM1/CV-series PLC program.

 Other Improvements

Previous version (version 7.0) New version (version 7.2)

The CPU Unit’s production information could be
displayed from the I/O table only.

The CPU Unit’s production information can be displayed from the

Main Menu’s PLC Information Dialog Box.
When a CS1D Duplex System CPU Unit was
being used, the CPU Unit’s Active/Standby
status could not be displayed in the project
directory tree.

When a CS1D Duplex System CPU Unit (CS1D-H) is being used,

the CPU Unit’s Active/Standby status is displayed in the project

directory tree.

Version 7.0 Upgrade Information

Functionality Improved from Version 6.1 to Version 7.0

 Compatible PLC Models

The following PLC models have been added as compatible PLCs as part of the
version 6.1 to version 7.0 upgrade.

 CS/CJ Series CPU Units with unit version Ver. 4.0 and higher

Ver. 4.0 and higher CS/CJ Series CPU Units are supported.

 CP Series CPU Units

The CP Series CPU Units (CP1H-Y) are supported.

 Support for NSJ-M3D Controllers

The NSJ@-@@@@(B)-M3D Controllers are supported.

 Ladder Program to Function Block Conversion Function

Previous version (Ver. 6.1) New version (Ver. 7.0)

To convert existing ladder programming to a
function block, the ladder programming was
copied and pasted into a function block
definition. At that point, it was necessary to
check the variables and addresses used in
the program and manually register those
variables and addresses while organizing the
input variables, internal variables, and output
variables.

Existing ladder program sections can be easily converted to function
blocks by selecting the program circuits to be converted and selecting
Function Block (ladder) generation. The function block definition is
created automatically and the variables are allocated automatically
based on the usage of the variables and addresses in the program.

 Online Editing of Function Blocks

Previous version (Ver. 6.1) New version (Ver. 7.0)

A function block definition (algorithm and
variable table) could not be edited while the
PLC program was being executed. (The
instance I/O parameters could be changed.)

A function block definition (algorithm and variable table) can be edited
while the PLC program is being executed. (Instances cannot be added.)
With this capability, it is possible to debug and edit the function block
definitions themselves even if the PLC must operate 24 hours/day
because there are devices that cannot be stopped. To edit a function
block, select the function block definition in the Workspace and select
FB Online Edit – Begin from the popup menu.

Note: Function block instances cannot be added.
Note: This function cannot be used for simulations on the CX-

Simulator.

 STRING Data and Text-processing Functions Supported in ST-language Function Blocks

Previous version (Ver. 6.1) New version (Ver. 7.0)

The STRING data type could not be used in
the ST language. (See note.)

The STRING data type can be used as a data type in the ST language.
With this capability, it is easy to set a variable containing text (ASCII) in
another variable with a substitution operation (such as: a := ‘@READ’;).
In this case, it is not necessary to know the length of the ASCII text
string.

OMRON PART 1: CX-Programmer

CX-Programmer_Page (xiv)

Previous version (Ver. 6.1) New version (Ver. 7.0)

There were no text-processing functions for
the ST language.
To process text for message displays and
no-protocol communications in the ladder
language, the user had to know the length of
the ASCII string and execute instructions
such as text-processing instructions, data
conversion instructions, and serial
communications instructions.
Note: The user can input text strings can in

I/O memory using the CX­Programmer’s PLC memory function,
but it is necessary to know the data
size in I/O memory.

Text-processing functions (extracting text, merging, searching, etc.) are
supported for the ST language. With these functions, it is easy to create
text strings and process displayed messages using ST language in a
function block without knowing the actual ASCII codes.

 Support for Input-Output Variables

Previous version (Ver. 6.1) New version (Ver. 7.0)

Input-output variables were not supported in
function blocks. (Only input variables, internal
variables, and output variables could be used.)

Input-output variables can be used in function blocks.

Input variables could not be specified as arrays. Input-output variables can be specified as arrays.
Values are passed from input parameters to
input variables.

Addresses (not values) are passed from input parameters to input

variables. Consequently, array input-output variables can be used in

the function blocks and large amounts of data can be passed easily

to the function blocks through input parameters.

 Support for C500/C120/C**P Backup Function

Previous version (Ver. 6.1) New version (Ver. 7.0)

The programs in C500/C120/C**P PLCs could
not be managed online from the CX­Programmer.

A program stored in a C500/C120/C**P PLC can be uploaded and

converted to a CS/CJ/CP Series program or CVM1/CV Series PLC

program. If an instruction’s specifications are different, a comment is

displayed to alert the user of the differences when the program is

converted. To convert a program, select Tools – C500/C120/CxxP

Support – Online PLC Program Conversion.

Program and I/O memory data (DM and HR) stored in a

C500/C120/C**P PLC can be backed up. Later, the backed up

program and I/O memory data can be restored to a C500/C120/C**P

PLC. To backup or restore the data, select Tools – C500/C120/CxxP

Support – Backup from PLC or Tools – C500/C120/CxxP Support

– Restore to PLC.

Program and I/O memory data (DM and HR) stored in a specified file

can be compared to the program and I/O memory data (DM and HR)

in a C500/C120/C**P PLC. To compare the data, select Tools –

C500/C120/CxxP Support – Compare PLC and file.

 Improvements in Data Trace/Time Chart Monitoring

Previous version (Ver. 6.1) New version (Ver. 7.0)

When inputting timer/counter
instructions, I/O comments
could not be input for
timer/counter numbers (first
operand) in the timer/counter
instruction.
I/O comments could be input
for timer/counter Completion
Flags, after which, these I/O
comments were
automatically displayed for
the timer/counter numbers
(first operand) of the
timer/counter instructions.

When inputting timer/counter instructions using simple dialog mode selected in the
Instruction Dialog Box, I/O comments can be input for the timer/counter number (first
operand) in the timer/counter instruction. (The Completion Flag of the timer/counter
instruction that corresponds to this number is automatically registered in the global
symbol table.)
Also, the … (three dots) button can be clicked in detailed dialog mode to display the
Find Symbol Dialog and then input a new symbol name using the NUMBER data type
for the timer/counter number (first operand) of the timer/counter instruction and the
symbol comment. The NUMBER type symbol will be registered in the local symbol table
and at the same time, the number of the timer/counter Completion Flag is registered in
the global symbol table.

 Online Connection to PLCs Connected Via Serial Gateway to Host Link FINS

Previous version (Ver. 4.0) New version (Ver. 5.0)

Online connection to PLCs
connected using a Serial
Gateway to Host Link FINS
was not supported.

Online connection is possible through the serial port of a Serial Communications
Board/Unit (Ver. 1.2 or later) to PLCs connected using Host Link FINS via a Serial
Gateway.
In the Change PLC Dialog Box, specify serial port 1 or 2 of the Serial Communications
Board/Unit (Ver. 1.2 or later) and the Host Link number of the destination PLC.

 Increased Data Link Capacity for Controller Link Networks and Areas 1 and 2 Can Use the

Same Area for Data Links (CS/CJ-series Controller Link Units Unit Ver. 1.2 (Available

Soon) or Later)

Previous version (Ver. 4.0) New version (Ver. 5.0)

A maximum of 12,000
send/receive words (total of
Area 1 and Area 2) per node
could be set when using
Controller Link data links
(manually set) with a CS/CJ­series Controller Link Unit.

Using a CS/CJ-series Controller Link Unit with Ver. 1.2 (available soon) or later, a
maximum of 20,000 send/receive words per node (total of Area 1 and Area 2) can be
set for nodes in Controller Link data links (manually set).

Area 1 and Area 2 had to be
in different areas when using
Controller Link data links
(manually set) with a CS/CJ­series Controller Link Unit.

A CS/CJ-series Controller Link Unit Ver. 1.2 (available soon) or later and Controller Link
data links (manually set) enables setting the same memory area for both Area 1 and
Area 2, provided that the addresses are not the same.
Example: The entire Data Link (i.e., Area 1 and Area 2) can be set in EM bank 0.

 Setting Local Network Tables (Using CX-Net Routing Tables) for the Serial Ports of Serial

Communications Boards/Units (Ver. 1.2 or Later)

Previous version (Ver. 4.0) New version (Ver. 5.0)

The following items could be

Version 4.0 Upgrade Information

The following tables outline the changes that have been made from version 3.3 to version 4.0 of the CX­Programmer.

 Functionality Improved from Version 3.3 to Version 4.0

Compatible PLCs

CX-Programmer Version 4.0 supports the following PLCs:

 CS/CJ-series CPU Unit Ver. 2.0 (including CJ1G-H Ver. 2.0, CJ1H-H Ver. 2.0, CJ1M

Ver. 2.0 (see note 1), CS1G-H Ver. 2.0, and CS1D-S Ver. 2.0)
 CS1D-H CPU Unit Ver. 1.1
Note: 1. Includes CJ1M-CPU11/21.

2. Although previously “CS1H-H” was selected as the device type for CS1D

CPU Units for Duplex-CPU Systems,

CX-Programmer Version 4.0 allows

selection of “CS1D-H.”

Network Compatibility

• Ethernet Connection Using TCP/IP

TCP/IP can be used instead of the earlier UDP/IP for Ethernet connections with a
PLC to which a CS1W-ETN21 or CJ1W-ETN21 100Base-TX Ethernet Unit is
mounted. Select Ethernet (FINS/TCP) as the network type.

• Settings for CS1D (Duplex) Ethernet Unit

Unit setting and PLC Setup settings are supported for the CS1D-ETN21D Duplex
Ethernet Unit, enabling duplex operation for Ethernet. Refer to the CS1D-ETN21D
Duplex Ethernet Unit Operation Manual (Cat. No. W430) for details on settings.

Improvements to Program Reusability

• Creating Files of Multiple Rungs or a Single Program Section as a File (Reusable File) for

Saving/Reading

Previous version (Ver. 3.3) New version (Ver. 4.0)

Reusing a part of the
program (multiple rungs or a
single section) enabled by
moving or copying between
two sections using the
Section/Rung Manager
Dialog Box. Parts of the
program, however, could not
be saved or read as files.

Parts of the program (single or multiple rungs, or a single program section) can be
saved as a file (.cxr: text file) by selecting File − Reusable File − Save As. The file can
then be read and inserted in a user-set location in the program of another project by
selecting File − Reusable File − Add to Project.
In the same way, specified variables in a symbol table can be saved as files, and then
read and inserted in a symbol table of another project.

Multiple reusable files can also be inserted all together in a specified order. The
order used to insert multiple reusable files can also be saved in the list of reusable
files added to the project. This allows the group of reusable files to be managed as
a single unit of data.

OMRON PART 1: CX-Programmer

CX-Programmer_Page (xxiv)

Improvements to Program Editing Efficiency

• Read Only Mode

Previous version (Ver. 3.3) New version (Ver. 4.0)

When editing a program offline,
editing could not be prohibited.

Allowing ladder screen display only, and prohibiting
program editing by mistake while offline is possible.
Set the Offline Edit Mode to Read Only Mode in the
Option Dialog Box to enable this function.

When editing a program, an
operation could be reversed
(Undo), but all the edited parts
could not be selected to be
either applied (store) or
cancelled.

After temporary editing of a specific rung, the user
can select to utilize (store) or delete (cancel) the
editing results.
Select Read Only Mode Edit – Start Edit from the
Edit Menu, and then perform either of the following
steps after editing.
a) To apply the editing results, select Read Only
Mode Edit – Store from the Edit Menu. The edited
contents will be reflected in the program.
b) To not apply the editing results, select Read Only
Mode Edit – Cancel from the Edit Menu. The edited
contents will be deleted.
Therefore, after editing rungs and writing and
recording temporary changes, the changes can be
selected to be either applied or deleted, enhancing
program editing efficiency

Improvements to Program Development in Task Units

• Downloading by Task (Program) (CS/CJ-series CPU Unit Ver. 2.0 or Later)

Previous version (Ver. 3.3) New version (Ver. 4.0)

When downloading a program
to the PLC, only the whole
user program could be
downloaded.
Note: Uploading in sections or
tasks (program) was possible
when using CS/CJ-, or
CVM1/CV-series PLCs.

Programs can be downloaded to CS/CJ-series PLCs
Ver. 2.0 or later, and downloading by task (program)
instead of the whole user program is possible.
Select Partial Transfer – Task Transfer to PLC from the
PLC Menu, and download a specified single task or
multiple tasks.
This function enhances the efficiency of program
development by multiple personnel.
Particularly, by downloading to the PLC by task
(program, only the parts to be changed are reflected in
the PLC, resulting in fewer working errors.

OMRON PART 1: CX-Programmer

CX-Programmer_Page (xxv)

• Confirming whether a Task (Program) Is Executing or Stopped (CS/CJ-series PLCs Only)

Previous version (Ver. 3.3) New version (Ver. 4.0)

CS/CJ-series PLCs supported
tasks, but the execution status
could be confirmed for the
whole program only and not
for each task.

The following executing/stopped status is displayed for
every task (see note) in the project space.

Note: Cyclic tasks only. Interrupt tasks not included.

• Running: Indicated as READY (execution enabled) or

RUN (executing status).

• Stopped: Indicated as INI (not executing status) or

WAIT (standby status).
This function improves debugging efficiency when
using multiple tasks.

• Checking Whether the Same Address Is Being Used by Another Task (Program): Cross

Reference Report Function (CS/CJ-series PLCs Only)

Previous version (Ver. 3.3) New version (Ver. 4.0)

CS/CJ-series PLCs supported
tasks, but they did not check
whether the same address
was being used by another
task (program).

By selecting Duplicate usage over programs in the
cross reference report function, a list can be checked
for any bits/words that have been allocated an address
already being used by another task (see note).
This function can be used to easily check whether the
same address is being used by another task
(programmer) when two or more programmers are
creating multiple tasks.
Note: Cyclic tasks only (interrupt tasks not included).

Improvements to Password Protection

• Password Protection for a Single User-set Task or Multiple Tasks (CS/CJ-series CPU Unit

Ver. 2.0 or later)

Previous version (Ver. 3.3) New version (Ver. 4.0)

Password protection
(reading/editing prohibited)
could be set.

Password protection (reading/editing prohibited) can be
set for a user-set single task or multiple tasks
(programs).
This function provides security and prevents the loss of
intellectual property for specific tasks (programs).

• Allowing/Prohibiting Creation of Program Files for File Memory (CS/CJ-series CPU Unit

Ver. 2.0 or Later)

Previous version (Ver. 3.3) New version (Ver. 4.0)

The user could use file
memory operations to transfer
program files (.OBJ) to a
Memory Card, even if UM
(user memory) read protection
was set with a password.

When a password is registered for the whole user
program or individual tasks, an optional setting can be
selected at the same time to allow/prohibit creation
(backup) of the program file (.OBJ).
This function prevents copying of user programs to
Memory Cards.

OMRON PART 1: CX-Programmer

CX-Programmer_Page (xxvi)

• Allowing/Prohibiting Program Overwriting (CS/CJ-series CPU Unit Ver. 2.0 or Later)

Previous version (Ver. 3.3) New version (Ver. 4.0)

Overwriting the user program
in the CPU Unit was
prohibited by turning ON pin 2
of the DIP switch. If pin 2 was
turned OFF, however,
overwriting was possible.

When a password is registered for the whole user
program or individual tasks, an optional setting can be
selected at the same time to allow/prohibit program
overwriting. Set the option in the PLC properties.
This function uses a password to prohibit overwriting of
the program by a third party.

Improvements to I/O Table Editing Functions

• Specifying up to 64 Sets of Slot/Rack Start Addresses

Previous version (Ver. 3.3) New version (Ver. 4.0)

For CS/CJ-series PLCs, up to
eight sets, comprising
rack/slot number and start
address, could be set.

For CS/CJ-series PLCs Ver. 2.0 or later, up to 64 sets
of rack/slot numbers and start addresses can be set.

Improvements to Unit Error Log Display

• Displaying Error Log for CPU Bus Units or Special I/O Units in the I/O Table

Previous version (Ver. 3.3) New version (Ver. 4.0)

The error log could not be
displayed for Special I/O
Units.

By selecting a CPU Bus Unit or Special I/O Unit in the
I/O table tree and clicking the right mouse button to
select the Unit Error Log Menu, the error log for the
selected Unit can be displayed.

Improvements to Ladder Screen Display Functions

• Addition of Horizontal Display Mode for Instructions

Previous version (Ver. 3.3) New version (Ver. 4.0)

Instructions could be
displayed in vertical writing
only.

Instructions on the right side of rungs, which were
previously displayed vertically only, can now also be
displayed horizontally. Enable this function by selecting

Tools – Options, and then selecting Show output
instructions horizontally in the Diagrams Tab Page (the

default setting is OFF: previously used vertical display).
By using the horizontal display mode, the number of
instruction rungs that can be printed and displayed on
one screen is increased, improving the readability of
the program. At the same time, the number of printed
pages can be reduced.

OMRON PART 1: CX-Programmer

CX-Programmer_Page (xxvii)

Improvements to Comment Functions

• Setting Multiple Comments (up to 16) for a Single Address, and Selecting a Label to Switch

All the Comments

Previous version (Ver. 3.3) New version (Ver. 4.0)

A single comment could be
set for each address (symbol)
only.

Multiple comments (up to 16) can be registered for
a single address (symbol). By selecting the
comment group to be displayed from the multiple
comment groups (up to 16 groups), the comments
on the ladder diagram screen can be changed all
at once.
This function allows multilingual development of a
single program or attachment of comments
according to the development step.

• Importing and Editing Rung Comments

Previous version (Ver. 3.3) New version (Ver. 4.0)

After uploading a program
from a PLC that did not
support rung comment data,
the rung comments could not
be reallocated.
Even when programs were
uploaded from PLCs that did
support rung comment data, if
the program in the personal
computer and actual PLC
were different, the rung
comments could not be
reallocated.

By selecting Section/Rung Manager from the Program
Menu, the rung comment data can be read (imported)
from the project in the personal computer, and
operations can be performed to move the data up and
down.
This function allows rung comments to be allocated to a
program all at once after uploading the program under
the following conditions, even if there is no comment
file (COMMENTS.CMT) in the Memory Card/EM file
memory.

1) When uploading programs from a C-series PLC or
other PLC that cannot record rung comments.

2) When uploading programs from a CS/CJ-series,
CVM1/CV-series, or C200HX/HG/HE-ZE PLC.
When the uploaded programs are changed in the actual
PLC using functions such as online editing, the position
of the rung comment can be edited.

OMRON PART 1: CX-Programmer

CX-Programmer_Page (xxviii)

• Displaying the Global/Local, Name, Address/Value, and Comment Fields for the Symbol at

the Cursor Position below the Ladder Section Window (Symbol Bar)

Previous version (Ver. 3.3) New version (Ver. 4.0)

To display all comments, the
font size, cell width, and other
settings must be changed in
the Appearance Tab settings,
or detailed dialog mode must
be used to check the
comment display.

The global/local, name,
address/value, and comment fields
for the symbol at the cursor position
are displayed in the symbol bar
below the Ladder Section window.
Enable this function by selecting
Show symbol bar in the Diagrams
Tab in the Options Dialog Box of the
Tools Menu (the default setting is
ON: display).
Therefore, while increasing the
program display density, the text in
particularly long comments can be
checked, thereby improving the
readability of the program.

Improvements to Cross Reference Functions

• Displaying/Printing Cross Reference Function Usage List with Comments

Previous version (Ver. 3.3) New version (Ver. 4.0)

The cross reference function
usage list was displayed
without comments.

The cross reference function usage list can be
displayed with comments and the list can also be
printed.
Therefore, the user can check what the addresses
mean when checking the number of times the
addresses have been used. This thereby reduces the
labor required for programming/debugging.
This function can also be used to jump to the position of
the rungs being used.

• Displaying the Cross Reference Function Usage List for the Corresponding Address from

the Ladder Screen

Previous version (Ver. 3.3) New version (Ver. 4.0)

The cross reference function
only enabled the cross
reference report to be
selected from the display
menu or a cross reference
pop-up display to be selected
from the display menu for the
address at the cursor position.

By moving the cursor to an address in the ladder diagram and selecting Check usage
including unused, the usage list (with comments) can be displayed starting with the
selected address.
This function enables the cross references to be checked for the address directly from
the ladder display instead of from the cross reference report.

OMRON PART 1: CX-Programmer

CX-Programmer_Page (xxix)

• Printing Word Address Cross References

Previous version (Ver. 3.3) New version (Ver. 4.0)

Printing with cross reference
information was possible for
the cross references of output
bits only (the rung number
used by the output bit address
was printed at the right of the
coil).

Printing with cross reference information also includes
the cross reference of the word address.
Therefore, by viewing the printed program, information
that is equivalent to that from the CX-Programmer’s
cross reference function can be obtained even if a CX­Programmer is not onsite.

Improvements to Search Functions

• Omitting Symbol Table from Search

Previous version (Ver. 3.3) New version (Ver. 4.0)

The search range included the
ladder program and symbol
table.

By deselecting Include symbol table, the search range
includes the ladder program only. Therefore,
unnecessary searches of symbol tables are omitted,
thereby shortening the search time.

• Specifying All the Search Targets

Previous version (Ver. 3.3) New version (Ver. 4.0)

Search targets were split into
addresses and comments,
etc.

By selecting All (strings) as the search target, a search
can be performed for all the search targets, including
addresses, constants, numbers, mnemonics, symbol
names, comments, rung comments, and other
comments.

• Mnemonic Function Code Input Not Required

Previous version (Ver. 3.3) New version (Ver. 4.0)

Mnemonic searches required

an asterisk * or parentheses ()
with function code inputs after
the mnemonic search target.

Mnemonic searches do not require an asterisk * or parentheses () with function codes
input after the mnemonic search target.

Improvements to Watch Window

• Displaying PVs of Addresses in the Watch Window Sheet in Binary

Previous version (Ver. 3.3) New version (Ver. 4.0)

The PV for each address
could be displayed in the
specified data type only.

A new column has been added to the watch sheet that
allows the PVs of addresses to always be displayed in
binary regardless of the settings specified in Data

Type/Format.
16 BIT (Binary, Channel) has also been added to the
Data Type/Format Options, allowing values to be

displayed in binary, even if the Binary column is hidden
(except in the Timer/Counter Areas).

OMRON PART 1: CX-Programmer

CX-Programmer_Page (xxx)

• Changing the PVs for DM/EM Areas in Bit Units

Previous version (Ver. 3.3) New version (Ver. 4.0)

PVs for DM/EM Area data
could not be changed in bit
units.

While online, when the binary display is selected in the
Set New Value dialog that is displayed when the
address in the watch window is clicked, the DM/EM
Area data can be changed into PVs in bit units.

Prevention of Leaving Set Forced Set/Reset Status

• Checking the Forced Set/Reset Status when Changing from Online to Offline

Previous version (Ver. 3.3) New version (Ver. 4.0)

After forced setting/resetting of
a bit online, the forced set/reset
status remained unchanged
when online status was
changed to offline status.

After forced setting/resetting of a bit online, a dialog
box is displayed when status returns to offline to allow
the forced set/reset status of addresses to be
displayed. The forced set/reset status can also be
cancelled.
Enable this function by selecting Tools − Options and
then selecting Check forced status after online
connection in the PLCs Tab Page (the default setting
is OFF: no confirmation).
This function prevents going offline unprepared when
the CPU Unit is still in forced set/reset status.

Improvements to Printing Functions

• Printing Ladder Programs as Shown on Screen

Previous version (Ver. 3.3) New version (Ver. 4.0)

Ladder programs could not be
printed as they were shown
on the screen.

Sections of the ladder program can be printed
separately as they are shown on the screen.
Select to print the ladder screen in the page setting.
The ladder screen can be printed as it is shown on the
ladder screen.
The program can also be printed at a smaller size
(Reduced size), or a larger size (Enlarged size), instead
of the standard size (Normal size).

Improvements to Multi-interlock Display Functions

• Displaying the Multi-interlock Status (CS/CJ-series CPU Unit Ver. 2.0 or Later)

Previous version (Ver. 3.3) New version (Ver. 4.0)

Interlock instructions allowing
nesting were not supported.

If the interlock instruction that allows nesting (multi
interlock instruction) is used with a CS/CJ-series PLC
Ver. 2.0 or later when performing online monitoring, the
display will show which instruction segment is presently
in interlock status using a tree-structure at the left of the
ladder screen (multi-interlock map). By double-clicking
the instruction in the multi-interlock map, the ladder
view will jump to the display of the applicable rung.

OMRON PART 1: CX-Programmer

There are some restrictions in using the CJ1M-CPU11/21 with the new version of CX-Programmer (version 3.3). These
restrictions will be eliminated in the next version.

OMRON PART 1: CX-Programmer

CX-Programmer_Page (xxxiii)

Function Restrictions when Using CX-Programmer Version 3.3 for the CJ1M-

CPU11/21

Restriction Description

Program capacity: 5 Ksteps max. Although the program capacity of the CJ1M-CPU12/22 is 10 Ksteps, the program

capacity of the CJ1M-CPU11/21 is 5 Ksteps. A program containing more than
5 Ksteps can be written offline, but an error will occur when it is transferred. An error
will also occur if a program transferred automatically when power is turned ON is

larger than 5 Ksteps.
Subroutine numbers for subroutine
instructions (SBS, GSBS, and
MCRO): 0 to 255 only

Although the subroutine numbers for the CJ1M-CPU12/22 are 0 to 1023, the

subroutine numbers for the CJ1M-CPU11/21 are 0 to 255. A program containing

subroutine numbers higher than 255 can be written and can be transferred, but an

error will occur when the program is executed.
Jump numbers for jump
instructions (JMP, CJP, and
CJPN): 0 to 255 only

Although the jump numbers for the CJ1M-CPU12/22 are 0 to 1023, the jump numbers

for the CJ1M-CPU11/21 are 0 to 255. A program containing jump numbers higher

than 255 can be written and can be transferred, but an error will occur when the

program is executed.
Use only 1 scheduled interrupt. Although the CJ1M-CPU12/22 support 2 scheduled interrupts, the CJ1M-CPU11/21

support only 1. Thus, only scheduled interrupt 0 can be used with the interrupt

instructions (MSKR, CLI, and MSKR). A program containing schedule interrupt 1 can

be written and can be transferred, but an error will occur when the program is

executed.
Use only 1 PWM output. Although the CJ1M-CPU12/22 support 2 PWM outputs, the CJ1M-CPU11/21 support

only 1. Thus, only PWM output 0 can be used with the PWM instruction. A program

containing PWM output 1 can be written and can be transferred, but an error will occur

when the program is executed.

Note: The Stop CPU on Instruction Error Option in the PLC Setup can be selected to stop program

execution by creating a fatal error when an instruction error is detected. Instruction errors include
instruction processing errors (the ER Flag will turn ON), DM/EM indirect addressing BCD errors, and
illegal access errors. This option can be used to check to see if instruction errors are occurring in
unexpected places in the program.

OMRON PART 1: CX-Programmer

Version 3.1 Upgrade Information

The following tables outline the changes that have been made from version 3.0 to version 3.1 of the CX­Programmer.

• Program Editing Functions

Improvements to Global Replacement Operation

Previous version (Ver. 3.0) New version (Ver. 3.1)

Changes between normally open
contacts and normally closed contacts
could be performed only with the / key.
They could not be performed globally.

If Change All is selected from the Edit menu and a checkmark is placed in the
checkbox for Invert open/close bit before performing a global replacement for the
PLC, all specified operands that are normally open contacts will be changed to
normally closed contacts and all normally closed contacts will be changed to

normally open contacts.
Global replacements for addresses
applied to both the ladder programs and
symbol data.

If the check box for symbols (including I/O comments) is cleared before an

address is replaced globally, the symbols table and I/O comments will not be

changed and only addresses in the ladder program will be changed.

If the check box for symbols (including I/O comments) is selected before an

address is replaced globally, the replacement operation will be the same as the

previous version.

Drawing or Deleting a Connecting Line by Dragging from the Start Point to the End Point

Previous version (Ver. 3.0) New version (Ver. 3.1)

Connecting lines could be input from the

mouse.)

Connecting lines can be drawn by clicking the Line Connect Mode icon and

then clicking the starting point and dragging to the end point. Connecting lines

can also be deleted by dragging after clicking the Line Delete Mode icon.

Note: A line can also be drawn by dragging on a line that is not connected on

one end.

Operand at the Cursor Position Appears as Default for Find or Replace Operations

Previous version (Ver. 3.0) New version (Ver. 3.1)

When performing a Find or Replace
operation, the previous contents of the
previous Find and Replace fields are
displayed regardless of the position of
the cursor.

When a Find or Replace operation is performed, the Bit Addresses, Addresses,

Values, Symbol Names, or Mnemonics (i.e., in the Look at field for each) at the

position of the cursor is displayed in the Find what field.

Note: If the Look at field is a Symbol comments or Program comments, the Find

what field will be blank.

History of Previous Find or Replace Settings

Previous version (Ver. 3.0) New version (Ver. 3.1)

No history of previous settings was

displayed for Find or Replace operations.

Histories of previous find and replace settings are displayed in pull-down menus

for the Find what field and Replace with field.

• Online Functions

• Monitor Functions

Display Form Setting for Operands for Special Instructions when Monitoring in Ladder

Section Windows

Previous version (Ver. 3.0) New version (Ver. 3.1)

When monitoring on the Ladder Section
window, the symbol data type was given
priority as the display format for
operands for special instructions.
For example, the data type for the MOV
instruction is CHANNEL, so the display
was always 4-digit hexadecimal.
The data type for MOVL is also
CHANNEL so the display was always 8­digit hexadecimal.
Also, for an unnamed symbol the data
type is CHANNEL so the display was
always 4-digit hexadecimal.

The display format for the present values of operands of special instructions

when monitoring on the Ladder Section Window can be selected from the

following data types. The same display format must be used globally.

To select the display format, click the desired button or select Monitoring Data

Type from the View menu.

• Decimal

• Signed Decimal

• Monitor in Hex

The default display formats will be as follows if none of the above display

formats is selected.

• Named symbol will be monitored in the symbol data type.

• Unnamed symbol will be monitored in the operand data type.

• Two-word operations, such as for the MOVL instruction, will be monitored in

2-word hexadecimal.

• For present values displayed in formats other than hexadecimal, “D” is

attached for 2-word data and “L” is attached for 4-word data.

Improvement in Operation to Change PVs for Special Instructions

Previous version (Ver. 3.0) New version (Ver. 3.1)

Present values were changed from the
menus.

Present values can be changed by pressing the Enter key on an operand that is

being monitored, or by double-clicking it.

Start Address Setting when Monitoring Present Values in I/O Memory

(Continuous Address Monitoring)

Previous version (Ver. 3.0) New version (Ver. 3.1)

The address to monitor in the PLC
Memory Window could not be specified
(either the screen had to be scrolled or
individual addresses had to be monitored
in Watch windows).
Also, with floating-point or double­precision floating-point binary, monitoring
was possible only from addresses
divisible by 2 or 4.

The start address to be monitored can be specified to monitor consecutive

addresses in the PLC Memory Window.

OMRON PART 1: CX-Programmer

CX-Programmer_Page (xli)

Monitoring Bit Status and Word Contents when Monitoring Present Values in I/O Memory

Previous version (Ver. 3.0) New version (Ver. 3.1)

Bit status displays in the PLC Memory
Window had to be performed in word
units.

When the binary word display format is selected for the PLC Memory Window,

bit status is displayed both for individual bits and as hexadecimal word values.

Simple Transfer of Data to the PLC when Monitoring Present Values in I/O Memory

Previous version (Ver. 3.0) New version (Ver. 3.1)

To transfer data changed in I/O memory
while monitoring, the monitor status had
to be cleared and then PLC | Transfer |
To PLC had to be selected, the range
specified, and the transfer specified in
the PLC Memory Window.

Individual cells being monitoring in the PLC Memory Window can be selected

and the Set | Value command or the Set Value button can be used to display

the Set Present Value dialog box. Data can be input into this dialog box for

individual I/O memory address and then the OK Button can be clicked to

directly change the value in the PLC.

When binary values are being displayed, the menus and buttons can be used to

Set, Reset, Force On, Force Off, or Force Cancel individual bits.

• Clear All Memory Areas Function

All Clear Operation for CPU Unit Memory (User Program, Parameter Area, and I/O Memory)

Previous version (Ver. 3.0) New version (Ver. 3.1)

Unless a memory error actually occurred in the PLC
the CPU Unit memory clear operation (see note) could
not be performed from the Error Log. Also there was no
function (all clear) to initialize the CPU Unit memory.
Note: The CX-Programmer had to be placed online,
PLC | Edit Error Log had to be selected to display the
Errors window, and then the Clear All Button had to be
clicked.

The user program, Parameter Area, and I/O Memory in the CPU
Unit can be cleared to initialize the CPU Unit by selecting Clear
All Memory Areas from the CX-Programmer's PLC menu or
selecting Clear All Memory Areas from the Options menu of the
PLC Errors dialog box.
These operations are possible even if a memory error has not
occurred in the PLC (the same as they are for a Programming
Console).

• On-line Editing

Power Flow Monitoring during Online Editing

Previous version (Ver. 3.0) New version (Ver. 3.1)

The power flow could not be monitored
during online editing.

The power flow is displayed during online editing in monitoring status.

I/O Comment Changes during Online Editing

Previous version (Ver. 3.0) New version (Ver. 3.1)

Changes to I/O comments made during
online editing could not be saved in the
CPU Unit (see note).
If changes were made, the symbol table
file had to be transferred to file memory
in a CS-, CJ-, CVM1, or CV-series PLC
or to the I/O comment area in UM (user
memory) in a C-series PLC.
Note: New I/O comments could be
added to the symbol table in CX­Programmer.

I/O comments can be changed during online editing in Ladder diagram view,

in the Symbol Table, or in I/O Comment View.

If I/O comments have been changed when online editing is ended, a

confirmation message will appear asking if the symbol table file should be

transferred to file memory in a CS-, CJ-, CVM1, or CV-series PLC or to the I/O

comment area in the allocated UM (user memory) in a C-series PLC.

Note 1: Symbol table names and addresses cannot be changed during online

editing.

Note 2: I/O comments with symbol names cannot be transferred to the I/O

comment area in UM (User Memory) in C-series PLCs.

CHAPTER 1
Technical Specifications

This chapter describes the CX-Programmer software in general terms and provides details of the operating
environment and minimum configuration necessary for the satisfactory operation of CX-Programmer.

CX-Programmer Software

CX-Programmer is a PLC programming tool for the creation, testing and maintenance of programs associated
with OMRON CS/CJ/CP-series PLCs, CV-series PLCs and C-series PLCs. It provides facilities for the support
of PLC device and address information and for communications with OMRON PLCs and their supported
network types.

CX-Programmer operates on IBM compatible personal computers with Pentium or better central processors,
including Pentium II. It runs in a Microsoft Windows environment (Microsoft Windows 95, 98, Millennium,
2000, XP, NT4.0 with Service Pack 5 or later, or Vista).

About this Manual

This User Manual acts as a reference for CX-Programmer by describing its various concepts and abilities, and
by leading the user through the basics of CX-Programmer programming. It also provides a detailed reference for
all of the CX-Programmer functions.

Separate OMRON manuals describe the PLC programming structure and instruction set in detail. A separate
OMRON manual describes the common features to PLC programming used by software other than CX­Programmer.

CX-Programmer comes with a context sensitive on-line help system which is designed to
complement this manual and to provide a quick reference at any point while using CX­Programmer when the manual is not to hand. This general help system uses a fast ‘hypertext
system’ which allows progressively more information about any topic to be obtained by
selecting keywords within the descriptive text.

Throughout this manual it is assumed that the reader has a working knowledge of Microsoft Windows, and
knows how to:

♦ Use the keyboard and mouse.
♦ Select options from Microsoft Windows menus.
♦ Operate dialog boxes.
♦ Locate, open and save data files.
♦ Edit, cut and paste text.
♦ Use the Microsoft Windows desktop environment.

If Microsoft Windows has not been used before, it is recommended that the reader spends some time working
with it using the Microsoft documentation before using CX-Programmer.

This manual also assumes that a working knowledge of OMRON PLC devices has been obtained.

CX-Programmer Features

CX-Programmer is a support tool for the programming of OMRON PLCs and for maintenance of their device
settings. It supersedes the OMRON applications SYSWIN and SYSMAC-CPT.
