*: When the CPU is in the RUN status and M9040 is OFF, the CPU remains in RUN
mode even if set to PAUSE.
!
Indicates the setting for the memory selection chip; one of the values 0 to 2 is set
in BIN code.
!
At each END instruction, if the scan time is shorter than the contents of D9017,
the new value is stored in this register. In other words, the minimum value for
scan time is stored in D9017, in BIN code.
! The scan time is stored in BIN code at each END instruction and is always
rewritten.
! At each END instruction, if the scan time is longer than the contents of D9019, the
new value is stored in this register. In other words, the maximum value for scan
time is stored in D9019, in BIN code.
! When user programs are executed at fixed intervals, used to set the execution
intervals, in 10 ms units.
0 : Constant scan function not used
1 to 200 : Constant scan function used
program executed at intervals of (set value)×10 ms.
