A-1 Differences in Available Functions
Depending on the CPU Unit (NJ or
CJ Series)
Some of the specifications when a CompoNet Master Unit is connected to a CJ-series CPU Unit are dif-
ferent from the specifications when the CompoNet Master Unit is connected to an NJ-series CPU Unit.
A list of these differences is provided below.
A-1-1 Functional Differences
There are differences in function support, function names, and specifications between when a Com-
poNet Master Unit is connected to a CJ-series CPU Unit and when the CompoNet Master Unit is
connected to an NJ-series CPU Unit.
Functions with Different Names
The names of the following functions are different between when a CompoNet Master Unit is connected
to a CJ-series CPU Unit and when the CompoNet Master Unit is connected to an NJ-series CPU Unit.
The corresponding names are listed in the following table.

Backup functions
*1 An NJ-series CPU Unit with unit version 1.03 or later and Sysmac Studio version 1.04 or higher are required.
A-1-2 Differences in Accessing Data from User Program
When the CompoNet Master Unit is used with an NJ-series CPU Unit, the device variables for the CJ-
series Unit are used as the basic means to access the CompoNet Master Unit from the user program.
The following tables give the I/O memory addresses in a CJ-series CPU Unit and the corresponding
device variables for CJ-series Units in the NJ-series CPU Unit. (The I/O memory of the CJ-series CPU
Unit is the same as the memory used for CJ-series Units.)
