CJ1-H-R CPU Unit
(High-speed)
Automatic allocation from right to left starting at Unit
closest to CPU Unit and then right to left on Expansion
Racks.
Supported (but operation is possible without creating
I/O tables from a Programming Device).
Either user-set I/O tables or automatic I/O allocation at
startup (no I/O table verification).
The default setting is for Automatic I/O Allocation at
Startup. User-set I/O tables can be automatically used
by setting and transferring I/O tables (or parameter file).
If the I/O tables are deleted from a CPU Unit from the
CX-Programmer, Automatic I/O Allocation at Startup
will be used again.
Possible only by using user-set I/O tables (set by edit-
ing I/O tables on the CX-Programmer and transferring
them to the CPU Unit).
I/O setting error occurs (fatal error). (Without Back-
planes and due to the physical connection method, it is
essentially impossible for a Unit to fall off or for an
empty position to be created. Discrepancies between
the registered I/O tables and actual I/O are thus consid-
ered to be far more serious.)
Supported.

Note 1. CX-Programmer version 7.1 or higher is required to use the new function-
ality of CJ1-H-R CPU Units.
2. Use a CJ1W-BAT01 Battery for the CJ1M CPU Unit.

CS-series
CS1-H CPU Unit
Automatic allocation from
right to left starting at Unit
closest to CPU Unit and
then right to left on Expan-
sion Racks.
Supported (must be cre-
ated from Programming
Device).
Only user-specified I/O
tables (I/O tables can be
verified against actual I/O).
Always possible. (Set by
editing I/O tables on the
CX-Programmer and
transferring them to the
CPU Unit.)
I/O verify error occurs
(non-fatal error).
