Comparison to CS-series PLCs Section 1-10
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.
I/O allocation Automatic allocation from right to left starting at Unit
closest to CPU Unit and then right to left on Expansion
Racks.
Automatic allocation from
right to left starting at Unit
closest to CPU Unit and
then right to left on Expan-
sion Racks.
Registered
I/O tables
Support Supported (but operation is possible without creating
I/O tables from a Programming Device).
Supported (must be cre-
ated from Programming
Device).
Modes 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.
Only user-specified I/O
tables (I/O tables can be
verified against actual I/O).
Allocating unused
words
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).
Always possible. (Set by
editing I/O tables on the
CX-Programmer and
transferring them to the
CPU Unit.)
Discrepancies between registered
I/O tables and actual I/O
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.)
I/O verify error occurs
(non-fatal error).
Setting first word on each Rack Supported.
Startup Mode when a Programming
Console is not mounted and the
PLC Setup is set to use operating
mode specified on the Program-
ming Console
RUN mode
Serial communications ports Same: One peripheral port and one RS-232C port.
Serial commu-
nications
modes
Peripheral port Same: Peripheral bus, Programming Console, Host Link, 1:N NT Link
RS-232C port Same: Peripheral bus, Host Link, 1:N NT Link, no protocol
Communications commands FINS commands, Host Link commands
Index registers Same
Diagnostic functions Same
Error log function Same
Debugging functions Same (Force-set/reset, differential monitor, data traces, instruction error traces)
I/O response time setting functions Same
