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 7.22 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.
Note CX-Programmer version 7.0 or lower cannot be used to confirm unit versions
for CP1L-L and CP1L-M CPU Units.
CX-Programmer version 7.21 or lower cannot be used to confirm unit versions
for CP1L-J CPU Units.
■Confirmation Procedure
Procedure When the Device Type and CPU Type Are Known

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 M , L or J .
3. Go online and select
PLC - Edit - Information
The PLC Information Dialog Box will be displayed.

viii
Use the above display to confirm the unit version of the CPU Unit.
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-X@@@@-@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 7.22 or higher is required to use CP1L-J CPU Units.
