All OMRON products are capitalized in this manual. The word “Unit” is also
capitalized when it refers to an OMRON product, regardless of whether or not
it appears in the proper name of the product.
The abbreviation “Ch,” which appears in some displays and on some OMRON
products, often means “word” and is abbreviated “Wd” in documentation in
this sense.
The abbreviation “PLC” means Programmable Controller. “PC” is used, how-
ever, in some CX-Programmer displays to mean Programmable Controller.
Visual Aids
The following headings appear in the left column of the manual to help you
locate different types of information.
Note Indicates information of particular interest for efficient and convenient opera-

Unit Versions of CP-series CPU Units
Unit Versions A “unit version” has been introduced to manage CPU Units in the CP Series
according to differences in functionality accompanying Unit upgrades.
Notation of Unit Versions
on Products
The unit version is given to the right of the lot number on the nameplate of the
products for which unit versions are being managed, as shown below.
Confirming Unit Versions
with Support Software
CX-Programmer version 6.1 or higher can be used to confirm the unit version
using one of the following two methods. (See note.)
•Using the PLC Information
• Using the Unit Manufacturing Information
Note CX-Programmer version 6.1 or lower cannot be used to confirm unit versions
for CP-series CPU Units.
PLC Information
• If you know the device type and CPU type, select them in the Change
PLC Dialog Box, go online, and select PLC - Edit - Information from the
menus.
• If you don't know the device type and CPU type but are connected directly
to the CPU Unit on a serial line, select PLC - Auto Online to go online,
and then select PLC - Edit - Information from the menus.
In either case, the following PLC Information Dialog Box will be displayed.

Use the above display to confirm the unit version of the CPU Unit.
Unit Manufacturing Information
In the IO Table Window, right-click and select Unit Manufacturing informa-
tion - CPU Unit.
The following Unit Manufacturing information Dialog Box will be displayed.

viii
Use the above display to confirm the unit version of the CPU Unit connected
online.
Using the Unit Version
Labels
The following unit version labels are provided with the CPU Unit.
These labels can be attached to the front of previous CPU Units to differenti-
ate between CPU Units of different unit versions.

These Labels can be used
to manage differences
in the available
functions among the Units.
Place the appropriate label
on the front of the Unit to
show what Unit
version is actually being
used.

Functions Supported by Unit Version for CP-series CPU Units
Functions Supported by
Unit Version 1.0 and 1.1
Functionality is the same as that for CS/CJ-series CPU Units with unit version
3.0. The functionality added for CS/CJ-series CPU Unit unit version 4.0 is not
supported.
CP1H CPU Units
• CX-Programmer version 6.11 or higher is required to use CP1H-X@@@@-
@/XA@@@@-@with unit version 1.1 or 1.0.
• CX-Programmer version 6.20 or higher is required to use CP1H-Y@@@@-
@with unit version 1.1.
Note 1. The unit version for the CP1H-X@@@@-@/XA@@@@-@begins at 1.0.
2. The unit version for the CP1H-Y@@@@-@begins at 1.1.
3. CX-Programmer version 7.11 or higher is required to use CP1L CPU Units
with unit version 1.0.
4. CX-Programmer version 7.3 or higher is required to use CP1L CPU Units
with 10 I/O points.

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 fol-
lowing section.
Definition of the CP Series
The CP Series is centered around the CP1H CPU Units and is designed with the same basic architec-
ture as the CS and CJ Series. The Special I/O Units and CPU Bus Units of the CJ Series can thus be
used. CJ-series Basic I/O Units, however, cannot be used. Always use CP-series Expansion Units and
CP-series Expansion I/O Units when expanding I/O capacity.
I/O words are allocated in the same way as the CPM1A/CPM2A PLCs, i.e., using fixed areas for inputs
and outputs.

Precautions provides general precautions for using the Programmable Controller and related devices.
Section 1 introduces the features of the CP1H and describes its configuration. It also describes the
Units that are available and connection methods for Programming Devices and other peripheral
devices.
Section 2 describes the names and functions of CP1H parts and provides CP1H specifications.
Section 3 describes how to install and wire the CP1H.
Section 4 describes the structure and functions of the I/O Memory Areas and Parameter Areas.
Section 5 describes the CP1H’s interrupt and high-speed counter functions.
Section 6 describes all of the advanced functions of the CP1H that can be used to achieve specific
application needs.
Section 7 describes how to use CP-series Expansion Units and Expansion I/O Units.
Section 8 gives an outline of the LCD Option Board, explains how to install and remove the LCD
Option Board, and describes the functions including how to monitor and make settings for the PLC. It
also lists the errors during operation and provides probable causes and countermeasures for trouble-
shooting.
Section 9 gives an outline of the Ethernet Option Board, explains how to install and remove the Ether-
net Option Board, and how to monitor and make settings required for operation. It also lists the errors
during operation and provides countermeasures for troubleshooting.
Section 10 describes the processes used to transfer the program to the CPU Unit and the functions
that can be used to test and debug the program.
Section 11 provides information on hardware and software errors that occur during CP1H operation.
Section 12 provides inspection and maintenance information.
Appendices provide product lists, dimensions, tables of Auxiliary Area allocations, and a memory
map.
