Differences in Available Functions
Depending on the CPU Unit (NJ or
CJ Series)
Some of the specifications when a Serial Communications Unit is connected to a CJ-series CPU Unit
are different from the specifications when the Serial Communications Unit is connected to an NJ-series
CPU Unit. A list of these differences is provided below.
There are differences in function support, function names, and specifications between when a Serial
Communications Unit is connected to a CJ-series CPU Unit and when the Serial Communications Unit
is connected to an NJ-series CPU Unit.
The following function cannot be used when the Serial Communications Unit is connected to an NJ-
series CPU Unit.
