Appendix B. Change of unit area allocation

This section describes the differences in unit area allocation between C200HX/HG/HE and CJ2.
Refer to related manuals for details.
Item
I/O allocation "Free location and fixed word allocation" "Free location and free word allocation"
Basic I/O
I/O allocation IR 100 to IR 199
Special I/O IR 400 to IR 459
(10 words allocated for each Unit No.)
DM 1000 to DM 2599
(100 words allocated for each Unit No.)
I/O allocation IR 030 to IR 049
Group-2 IR 330 to IR 341
High-density I/O (2 or 4 words allocated for each I/O
word)
Link Relay Area (LR) LR 00 to LR 63
Special Relay Area SR 236 to SR 255
(SR) SR 256 to SR 299
Auxiliary Relay Area AR 00 to AR 27
(AR)

(In SR Area)
Optical I/O Unit and IR 200 to IR 231
I/Terminal Area
DeviceNet Area and IR 050 to IR 099

Holding Relay Area HR 00 to HR 99
(HR)
Error Log Area DM 6000 to DM 6030

Appendix C. Change in PLC Settings

Item
PLC Setup Always uses the DM Area (DM 6600 to
DM 6655

Appendix D. Change of execution timing etc.

Item
Interrupt execution Write interrupt programs in subroutines. Write interrupt programs in interrupt
method and execution
timing
I/O table registration Not required
Cycle time -
20
C200HX/HG/HE
C200HX/HG/HE
C200HX/HG/HE
CJ2
Change the word and bit addresses
used in the program.
CIO 2000 to CIO 2199
(10 words allocated for each Unit No.)
D20000 to D21999
(100 words allocated for each Unit No.)
Change the word and bit addresses
used in the program.
The allocation is decided in the same
way as Basic I/O Units depending on
the installed position (rack and slot).
Change the word and bit addresses
used in the program.
None
(1) Auxiliary Area and bits
Change the word and bit addresses
used in the program.
(2) Condition flags and clock pulses
Change the arithmetic flags in the
program to the condition flags. Clock
pulses are specified using global
symbols, such as "P_0.1ms" and
"P_1ms".
None
None
[DeviceNet Area]
CIO 3200 to CIO 3799
[SYSMAC BUS Area]
None
CIO 1200 to CIO 1499
CIO 3800 to CIO 6143
W000 to W511
TR 00 to TR 15
HR 000 to HR 959
A100 to A199
CJ2
Uses dedicated area for PLC settings
(there is no address for setting by
users).
CJ2
tasks.
Required
I/O tables must be created with the
CX-Programmer or other programming
device.
The cycle time is shortened with CS1.
If the system operation is affected by
cycle time, check the operation after
conversion.
Description
Refer to the

SYSMAC CJ SERIES CJ2
CPU UNIT SOFTWARE
USER'S MANUAL (Cat. No.
W473) for details on I/O
allocation.
PC Link cannot be used with
CJ2.
In CJ2, operation flags and
condition flags are specified
by labels.
PC Link cannot be used with
CJ2.
The Optical I/O Unit cannot
be used with CJ2.
SYSMAC BUS cannot be
used with CJ2.
Change the program if the
Error Log Area is read in the
program.
Description
Refer to related manuals for
details.
Description
In CJ2, interrupt tasks are
executed even when an
instruction is being executed
or I/O is being refreshed.
To keep the same cycle time
as C200HX/HG/HE, set
Minimum Cycle Time in the
PLC Setup.
