Operands:
S : Lower bound of the comparison zone S

speed counter D: Comparison result (3 consecutive devices)
Explanations:
1. S should be equal to or smaller than S
1
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 2.12 in this manual.
