(1) AR Area and Bit:
Change the word address and bit
address used in the program.
(2) Condition Flag and clock pulse:
Change the operation flags in the
program to the condition flags and
the clock pulse respectively. Use
global variables such as P_0_1ms,
and P_1ms instead of clock pulse.
Remark
Refer to CS-series CPU
Unit Operation Manual (Cat.
No. W339) for details of the
I/O allocation.
* This is the allocation when
a C200H SYSMAC BUS
Unit is used with a
CS-series CPU Unit.
CS series CPU do not
support SYSMAC BUS/2.
Consider replacing it with
other remote I/O system.
Areas unused can be used
as Work Area with
CS-series. However, some
area will be used for future
expansion. Therefore, do
not use the area.
CPU status and the clock
have been allocated to
Auxiliary Area (AR) with
CS-series CPU Unit.
The operation flags and the
condition flags are specified
with the label.
