Operands:

: Lower bound of the comparison zone S

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

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

Explanations:

1. S

should be equal to or smaller than S

≦ S

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.
