Appendix B. Change of unit area allocation
This section describes the differences in unit area allocation between C200H and CS1. Refer to related manuals for details.
Item
C200H
CS1
Description
I/O allocation
Basic I/O
"Free location and fixed word allocation"
"Free location and free word allocation"
Change the word and bit addresses
used in the program.
For CS1, it is necessary to
register the I/O table.
I/O allocation
Special I/O
IR 100 to IR 199
(10 words allocated for each Unit No.)
DM 1000 to DM 1999
(100 words allocated for each Unit No.)
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.
Refer to the
CS1G/H-CPU□□H CS Series
Programmable Controllers
OPERATION MANUAL (Cat.
No. W339) for details on I/O
allocation.
I/O allocation
Group-2
High-density I/O
IR 030 to IR 049
(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.
Special Relay Area
(SR)
SR 236 to SR 255
(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".
In CS1, operation flags and
condition flags are specified
by labels.
Link Relay Area
(LR)
LR 00 to LR 63
CIO 1000 to CIO 1063
Change the word and bit addresses
used in the program.
SYSMAC BUS Area
IR 050 to IR 099
CIO 3000 to CIO 3049
Change the word and bit addresses
used in the program.
Error Log Area
DM 969 to DM 999
A100 to A199
Change the program if the
Error Log Area is read in the
program.
Appendix C. Change in PLC Settings
Item
C200H
CS1
Description
Startup mode
Setting switch on the memory unit
Set Startup Mode in the PLC Setup.
Constant Cycle Time
function
Constant Cycle Time (FUN18)
Set Cycle Time in the PLC Setup.
Use the DI (DISABLE
INTERRUPTS) instruction and
EI (ENABLE INTERRUPTS)
instruction to maintain
concurrency between cyclic
tasks and interrupt tasks.
Appendix D. Change of execution timing etc.
Item
C200H
CS1
Description
Interrupt execution
method and execution
timing
Write interrupt programs in
subroutines.
Write interrupt programs in interrupt
tasks.
In CS1, interrupt tasks are
executed even when an
instruction is being executed
or I/O is being refreshed.
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 C200H, set Minimum Cycle
Time in the PLC Setup.
Read Protection
function
FUN49
Use password protection function of the
CX-Programmer.
