Operands:

S1: Comparative value S2: No. of high speed counter

D: Comparison result

Explanations:

1.DHSCR compares the current value of the counter S2 against a compare value S1. When the counters current value changes to a value equal to S1, then device D is reset to OFF. Once reset, even if the compare result is no longer unequal, D will still be OFF.

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

3.Operand D can be specified with high speed counters C232~C254 (SS2/SA2/SE does not support C232) the same as S2. .

4.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.

5.For explanations on software counters and hardware counters, please refer to API53 DHSCS.

6.For program examples, please refer to Program Example1 and 2 in API53 DHSCS.
