Confirming Unit Versions with System-defined Variable

You can access the _UnitVersion (Unit Version) system-defined variable from the user program to check
the unit version of the CPU Unit.
_UnitVersion is an USINT array variable with two elements. _UnitVersion[0] and _UnitVersion[1] corre-
spond to the integer part and the fractional part of the unit version, respectively.
Version Information
A CPU Unit with unit version 1.08 or later and the Sysmac Studio version 1.09 or higher are
required to confirm the unit version using the system-defined variable.
Additional Information
Refer to the manual for the specific Unit for the unit versions of the CPU Units, Communications
Coupler Units, NX Units, and Safety Control Units to which the database connection service and
other functions were added.

Unit Versions and Sysmac Studio Versions

The functions that are supported depend on the unit version of the NJ-series CPU Unit. The version of
Sysmac Studio that supports the functions that were added for an upgrade is also required to use those
functions. Refer to A-8 Version Information for the relationship between the unit versions of the CPU
Units and the Sysmac Studio versions, and for the functions that are supported by each unit version.
