Unit Versions of CS/CJ-series Controller Link Units
Unit Versions
A “unit version” has been introduced to manage CS/CJ-series Controller Link Units according to differ-
ences in functionality accompanying upgrades.
Unit Version Notation on Products
The unit version code is provided on the nameplate of the CS/CJ-series Controller Link Units for which
unit versions are being managed. This system applies to Controller Link Units with unit version 1.2 or
later.
Confirming Unit Versions with Support Software
CX-Programmer version 5.0 or higher can be used to confirm the unit version in the Unit Manufacturing
Information.
1,2,3... 1. 1. In the I/O Table Window, right-click on the Controller Link Unit, and then
select Unit Manufacturing Information.
2. The following Unit Manufacturing Information Dialog Box will be displayed.
Example: In this Unit Manufacturing Information Dialog Box, unit version
1.2 is displayed. Use this dialog box to confirm the unit version of the Con-
troller Link Unit that is connected online.

Using the Unit Version Labels
Unit version labels are provided with the product. These labels can be attached to the front of previous
Controller Link Units to differentiate between Controller Link Units of different unit versions.
Unit Version Notation
The unit versions are indicated in this manual as follows:
Function Support by Unit Version
Note Use the CX-Net in CX-Programmer version 5.0 or later to set a data link area
in which the number of send and receive words exceeds 12,000 words, or to
set data link tables that allocate the same area for Area 1 and Area 2.
