allocation.
I/O allocation
Group-2
High-density I/O
IR 030 to IR 049
IR 330 to IR 341
(2 or 4 words allocated for each I/O
word) 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.
Link Relay Area (LR) LR 00 to LR 63 None PC Link cannot be used with
CJ2.
Special Relay Area

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". In CJ2, operation flags and
condition flags are specified
by labels.
PLC Link Words SR 247 to SR 250

Error Log Area DM 6000 to DM 6030 A100 to A199 Change the program if the
Error Log Area is read in the
program.
Appendix C. Change in PLC Settings
Item C200HX/HG/HE CJ2 Description
PLC Setup Always uses the DM Area (DM 6600 to
DM 6655 Uses dedicated area for PLC settings
(there is no address for setting by
users). Refer to related manuals for
details.
Appendix D. Change of execution timing etc.
Item C200HX/HG/HE CJ2 Description
Interrupt execution
method and execution
timing Write interrupt programs in subroutines. Write interrupt programs in interrupt
tasks.
In CJ2, interrupt tasks are
executed even when an
instruction is being executed
or I/O is being refreshed.
I/O table registration
Not required
Required
I/O tables must be created with the
CX-Programmer or other programming
device.
Cycle time - The cycle time is shortened with CS1.
If the system operation is affected by
cycle time, check the operation after
conversion. To keep the same cycle time
as C200HX/HG/HE, set
Minimum Cycle Time in the
PLC Setup.
