D9017 Scan time
Minimum scan time
(per 10 ms)
• If scan time is smaller than the content of D9017, the
value is newly stored at each END. Namely, the
minimum value of scan time is stored into D9017 in
BIN code.
Usable with all
types of CPUs.
D9018 Scan time Scan time (per 10 ms)
• Scan time is stored in BIN code at each END and
always rewritten.
Usable with all
types of CPUs.
D9019 Scan time
Maximum scan time
(per 10 ms)
• If scan time is larger than the content of D9019, the
value is newly stored at each END. Namely, the
maximum value of scan time is stored into D9019 in
BIN code.
Usable with all
types of CPUs.

Constant scan
Constant scan time
(Set by user in 10 ms
increments)
• Sets the interval between consecutive user program
starts in multiples of 10 ms.
0: No setting
1 to 200: Set. Program is executed at intervals of (set
value) × 10 ms.
Unusable with
An.
D9021 Scan time Scan time (1 ms unit)
• Scan time is stored and updated in BIN code after
every END.
—
Usable with
AnA, A2AS,
AnU, AnA board
and QCPU-A
(A Mode).
D9022
1 second
counter
Counts 1 every
second.
• When the PC CPU starts running, it starts counting 1
every second.
• It starts counting up from 0 to 32767, then down to -
32768 and then again up to 0. Counting repeats this
routine.
