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.
