13 High-Speed Processing – FNC 50 to FNC 59

13.6 FNC 55 – HSZ / High-Speed Counter Zone Compare

Timing chart

In the part [1] in the timing chart, Y010 remains OFF if the current value of a high-speed counter (C235 in the example
below) is "0" when restoring the power.
1) For initializing Y010, the current value of C235 is compared with K1000 and K1200, and Y010 is driven using the

DZCPP instruction (for general zone comparison) as pulse operation only upon startup.

2) The comparison result in Y010 is latched until an input pulse is input and the comparison output is driven by the

DHSZ instruction.

3) According to the current value of the counter, the DHSZ instruction drives the output (A), (B) or (C).
