Auxiliary Area (AR) with
CS-series CPU Unit.
Auxiliary Area A 000 to 511 (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. The operation flags and the
condition flags are specified
with the label.
