Explanation of function and operation
1. 32-bit operation (DHSZ)
The current value of a high-speed counter (C235 to C255) specified in
(comparison value 1 and comparison value 2). Based on the comparison result, "smaller than the lower comparison
value", "inside the comparison zone" or "larger than the upper comparison value", one among
D +2 is set to ON regardless of the operation cycle.
In this instruction, the comparison processing is executed after the count processing in the high-speed counter.
