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, and CJ1M CPU Units, as well as
the CS1D CPU Units for Single CPU Systems, begins at version 2.0.
• The unit version of the CS1D CPU Units for Duplex CPU Systems, begins
at version 1.1.
• 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.
System Configuration Support by Unit Version
Note 1. OK: Supported, ---: Not supported
2. Only CS1D-CPU@@H/P CPU Units with unit version 1.3 support the Du-
plex CPU, Dual I/O Expansion System. If a Dual I/O Expansion System is
connected to a CPU Unit with an earlier unit version, an I/O bus error will
occur and the PLC will not operate.
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.
