Explanation
This register stores any of the values from 0 to B, indicating
which program is currently running.
If a scan time value is smaller than the value in SD1017, the
SD1017 value is updated in the END processing. Therefore
the minimum value of scan time is stored in SD1017.
This register stores a scan time in every END processing.
If a scan time value is greater than the value in SD1019, the
SD1019 value is updated in END processing. Therefore the
maximum value of scan time is stored in SD1019.
This register stores an interval value in units of 10ms to run
a program at regular intervals.
• 0: No constant scan function
• 1 to 200: Constant scan function available (executing at
an interval of setting value  10ms)
This register stores scan time in every END processing.
• The value is incremented by one every second after
RUN.
• The counter starts the routine: counts up from 0 to 32767,
then counts down to -32768 and then again counts up to
0.
This register stores the year (last two digits) and month in
BCD as shown below.
