• Sets the interval between consecutive program starts in multiples
of 10 ms.
0 : No setting
1 to 200 : Set. Program is executed at intervals of (set
value) 10 ms.
• At every END, the scan time is stored in BIN code and always
rewritten.
• 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.
• The year (last two digits) and month are stored as BCD code as
shown below.
b15 to b12 b11 to b8 b7
