Comparison Operator
0: ≤
(Comparator bit turns ON when
8-digit counter PV ≤ Comparison data 2.)
1: ≥
(Comparator bit turns ON when
8-digit counter PV ≥ Comparison data 2.)
Comparison Data 2
1: SV (constant)
Note: Always 1.
Comparison Data 1
000 (H'0): 8-digit counter (F) PV
The bit position is specified when reading. In
this example, the bit 02 is specified when
