Operands:

S1: Lower bound of the comparison zone

S2: Upper bound of the comparison zone S: No. of

high speed counter D: Comparison result (3 consecutive devices)

Explanations:

1.S1 should be equal to or smaller than S2 (S1 ≦ S2).

2.If D is specified as Y0~Y3 in this instruction, the compare result will immediately output to the external outputs Y0~Y3. However, other Y outputs will still be updated till the end of program. Also, M and S devices, not affected by the program scan cycle, will be immediately updated as well.

3.High speed counters include software high speed counters and hardware high speed counters. In addtiion, there are also two types of comparators including software comparators and hardware comparators. For detailed explanations of high speed counters please refer to section 2.9 in this manual.
