Appendix B. Change of unit area allocation

This section describes the difference of unit area allocation in C200H and CS1-series. Refer to related manuals for details.

C200H-series
"Free location and fixed channel"
IR 100 to 199
(10words allocated for each Unit
No.)
DM1000 to 1999
(100words allocated for each Unit
No.)
IR 30 to 49
(2 or 4 words allocated for each
Unit)
SR 236 to 255
LR00 to LR63
50 to 99
DM 969 to 999
C200H-series
Setting switch on the memory unit
Constant Cycle Time (FUN18)
C200H-series
Write the interrupt program in
subroutine.
-
FUN49
CS1-series
"Free location and free channel"
Change the channel and bit address
used in the program.
CIO 2000 to 2199
(10words allocated for each Unit No.)
DM20000 to 21999
(100words allocated for each Unit
No.)
Change the channel and bit address
used in the program.
The allocation is decided in the same
way as a Basic I/O Units depending
on the installed position (rack and
slot).
Change the channel and bit address
used in the program.
(1) AR Area and Bit.
Change the channel and bit address
used in the program.
(2) Condition flags and clock pulse
Change the operation flags in the
program to the condition flags. Use
the global symbols such as P_0.1ms
and P_1ms instead of the clock
pulse.
CIO 1000 to 1063
Change the channel and bit address
used in the program.
CIO 3000 to 3049
Change the channel and bit address
used in the program.
AR 100 to A199
CS1-series
Select the "Mode" at power ON from
PLC settings.
Enter the value in the "Constant Cycle
Time" from PLC settings.
CS1-series
Write the interrupt program in interrupt
task.
The cycle time is shortened with CS1.
If the system operation is affected by
cycle time, check the operation with
the converted program.
Use password protection function of
CX-Programmer.
Description
For CS1-series, it is
necessary to register I/O
table.
Refer to CS1G/H-CPU**H
/CS1G/H-CPU**-EV1 CS
SERIES CPU UNITS
OPERATIAN MANUAL
(Cat. No. W339) for details
on I/O allocation.
Operation flags and
condition flags of CS1 can
be specified by label.
Change the program if the
Error History Area is read in
the program.
Description
Use DI (DISABLE
INTERRUPTS) instruction
and EI (ENABLE
INTERRUPTS) instruction
when simultaneity of data is
required between the Cycle
Tasks and Interrupt Tasks.
Description
For CS1, an Interrupt Task is
executed even when an
instruction is being executed
or I/O refreshing.
To obtain the same cycle
time as C200H, set the time
from the "Constant Cycle
Time" in the PLC settings
