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 7.3 or higher can be used to confirm the unit version
of the CP1L-L CPU Unit with 10 I/O points.
CX-Programmer version 7.22 or higher can be used to confirm the unit ver-
sion of the CP1L-J CPU Unit.
CX-Programmer version 7.1 or higher can be used to confirm the unit version
of the CP1L-L and CP1L-M CPU Unit with 14, 20, 30, 40 or 60 I/O points.
Note CX-Programmer version 7.2 or lower cannot be used to confirm unit versions
for CP1L-L CPU Units with 10 I/O points.
CX-Programmer version 7.21 or lower can be used to confirm the unit version
of the CP1L-J CPU Unit.
CX-Programmer version 7.0 or lower cannot be used to confirm unit versions
for CP1L-L and CP1L-M CPU Units with 14, 20, 30, 40 or 60 I/O points.

■Confirmation Procedure
Procedure When the Device Type and CPU Type Are Known
1,2,3... 1. Set the Device Type Field in the Change PLC Dialog Box to CP1L .
2. Click the Settings Button by the
Device Type Field and, when the Device
Type Settings Dialog Box is displayed, set the
CPU Type Field to J, L, L10
or M .

ix
Procedure When the Device Type and CPU Type Are Not Known
This procedure is possible only when connected directly to the CPU Unit with
a serial connection.
If you don't know the device type and CPU type that 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.
The PLC Information Dialog Box will be displayed and can be used to confirm
the unit version of the CPU Unit.

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.
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.

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.

Precautions provides general precautions for using the Programmable Controller and related devices.
Section 1 introduces the features of the CP1L 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 CP1L parts and provides CP1L specifications.
Section 3 describes how to install and wire the CP1L.
Section 4 describes the structure and functions of the I/O Memory Areas and Parameter Areas.
Section 5 describes the CP1L’s interrupt and high-speed counter functions.
Section 6 describes all of the advanced functions of the CP1L 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 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 9 provides information on hardware and software errors that occur during CP1L operation
Section 10 provides inspection and maintenance information.
The
Appendices provide product lists, dimensions, tables of Auxiliary Area allocations, and a memory
map.
