Notice:

OMRON products are manufactured for use according to proper procedures by a qualified operator

and only for the purposes described in this manual.

The following conventions are used to indicate and classify precautions in this manual. Always heed

the information provided with them. Failure to heed precautions can result in injury to people or dam-

age to property.

!DANGER Indicates an imminently hazardous situation which, if not avoided, will result in death or

serious injury. Additionally, there may be severe property damage.

!WARNING Indicates a potentially hazardous situation which, if not avoided, could result in death or

serious injury. Additionally, there may be severe property damage.

!Caution Indicates a potentially hazardous situation which, if not avoided, may result in minor or

moderate injury, or property damage.

OMRON Product References

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, however, in some Program-

ming Device 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.

Unit Versions of CS/CJ-series CPU Units

Unit Versions A “unit version” has been introduced to manage CPU Units in the CS/CJ

Series according to differences in functionality accompanying Unit upgrades.

This applies to the CS1-H, CJ1-H, CJ1M, and CS1D CPU Units.

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.

• CS1-H, CJ1-H, and CJ1M CPU Units (except for low-end models) manu-

factured on or before November 4, 2003 do not have a unit version given

on the CPU Unit (i.e., the location for the unit version shown above is

blank).

• The unit version of the CS1-H, CJ1-H, CJ1M and CS1D-CPU@@S CPU

Units begins at version 2.0.

• The unit version of the CS1D-CPU@@H begins at version 1.1.

• The unit version of the CS1D-CPU@@HA/SA begins at version 4.0.

• CPU Units for which a unit version is not given are called Pre-Ver. @.@

CPU Units, such as Pre-Ver. 2.0 CPU Units and Pre-Ver. 1.1 CPU Units.

Confirming Unit Versions

with Support Software

CX-Programmer version 4.0 or later can be used to confirm the unit version

using one of the following two methods.

• Using the PLC Information

• Using the Unit Manufacturing Information (This method can be used for

Special I/O Units and CPU Bus Units as well.)

Note CX-Programmer version 3.3 or lower cannot be used to confirm unit versions.

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.

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.

Unit Version Notation In this manual, the unit version of a CPU Unit is given as shown in the follow-

ing table.

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.

2. Only CS1D-CPU@@H/P CPU Units with unit version 1.3 or later support

the Duplex CPU, Dual I/O Expansion System. If a Dual I/O Expansion Sys-

tem is connected to a CPU Unit with an earlier unit version, an I/O bus error

will occur and the PLC will not operate.

Troubleshooting Problems with Unit Versions on the CX-Programmer

Problem Cause Solution

After the above message is displayed, a compiling

error will be displayed on the Compile Tab Page in the

Output Window.

An attempt was made using CX-

Programmer version 4.0 or higher

to download a program contain-

ing instructions supported only by

CPU Units Ver. 2.0 or later to a

Pre-Ver. 2.0 CPU Units.

Check the program or change

the CPU Unit being down-

loaded to a CPU Unit Ver. 2.0

or later.

An attempt was made using CX-

Programmer version 4.0 or higher

to download a PLC Setup con-

taining settings supported only by

CPU Units Ver. 2.0 or later (i.e.,

not set to their default values) to a

Pre-Ver. 2.0 CPU Units.

Check the settings in the PLC

Setup or change the CPU Unit

being downloaded to a CPU

Unit Ver. 2.0 or later.

“????” is displayed in a program transferred from the

PLC to the CX-Programmer.

CX-Programmer version 3.3 or

lower was used to upload a pro-

gram containing instructions sup-

ported only by CPU Units Ver. 2.0

or later from a CPU Unit Ver. 2.0

or later.

The new instructions cannot

be uploaded using CX-Pro-

grammer version 3.3 or lower.

Use CX-Programmer version

4.0 or higher.

The above error is displayed when a project file is

read.

An attempt was made to read a

project file for an unsupported

unit version.

Click the Yes Button to initial-

ize unsupported settings and

read the file. Click the No But-

ton to cancel reading the

project file.

The above warning is displayed when going online.

An attempt was made to go

online with an earlier version of a

CPU Unit for a project file that

contains an extended read pro-

tection setting that is supported

only by a newer version of the

CPU Unit.

Change the protection setting

in the PLC Properties Dialog

Box. Or, replace the CPU Unit

with which you need to go

online with a higher version of

CPU Unit.

About this Manual:

This manual describes the installation and operation of the CS1D Duplex Programmable Controllers

(PLCs) and includes the sections described below. The CS Series and CJ Series are subdivided as

shown in the following table.

Please read this manual and all related manuals listed in the table on the next page and be sure you

understand information provided before attempting to install or use CS1D-CPU@@HA/SA/H/S CPU

Units in a PLC System.

Process-control CPU Units refer to CPU Units with the models CS1D-CPU@@P. Each Process-control

CPU Unit consists of a CS1D-CPU@@H CS1D CPU Unit and a CS1D-LCB05D Loop Control Board as

a set.

Precautions provides general precautions for using the CS1D Programmable Controllers (PLCs) and

related devices, including the CS1D-CPU@@H CPU Units for Duplex CPU Systems, CS1D-CPU@@S

CPU Units for Single CPU Systems, CS1D-DPL01 Duplex Unit, and CS1D-PA/PD@@@ Power Supply

Unit.

Section 1 introduces the special features and functions of the CS1D Duplex PLCs and describes the

differences between these PLCs and other PLCs.

Section 2 provides the specifications, defines the nomenclature, and describes the functions of CS1D

PLCs.

Section 3 describes the basic operation of a Duplex System.

Section 4 outlines the steps required to assemble and operate a CS1D Duplex PLC system.

Section 5 describes how to install a PLC System, including mounting the various Units and wiring the

System. Be sure to follow the instructions carefully. Improper installation can cause the PLC to mal-

function, resulting in very dangerous situations.

Section 6 describes the settings in the PLC Setup and how they are used to control CPU Unit opera-

tion.

Section 7 describes I/O allocations to Basic I/O Units, Special I/O Units, and CPU Bus Units, and data

exchange with Units.

Section 8 describes the structure and functions of the I/O Memory Areas and Parameter Areas.

Section 9 describes the internal operation of the CPU Unit and the cycle used to perform internal pro-

cessing.

Section 10 provides information on hardware and software errors that occur during PLC operation.

Section 11 provides inspection and maintenance information.

The Appendices provide Unit specifications, Auxiliary Area words and bits, a memory map of internal

addresses, and PLC Setup coding sheets, RS-232C port connection information, and precautions

when upgrading a system to duplex operation with CS1D PLCs
