14 HIGH-SPEED COUNTER INSTRUCTION
14.1 High-speed Processing Instruction
Comparison of 32-bit data band
DHSZ
This instruction compares the current value of a high-speed counter with two values (one zone), and outputs the comparison
result (refresh). The high-speed pulse input/output module is not supported.

Applicable devices
*1 Enable the FX3 compatible function, and specify a device between LC35 and 55 that is designated as an FX3 compatible high-speed
counter. For FX3 compatible function, refer to
MELSEC iQ-F FX5 User's Manual (Application).
Processing details
• The current value of a high-speed counter specified in (s3) is compared with two comparison points (comparison value 1
and comparison value 2). Based on the zone comparison result, "smaller than the lower comparison value", "inside the
comparison zone" or "larger than the upper comparison value", one among (d), (d)+1 and (d)+2 is set to ON regardless of
the scan time. For details, refer to
MELSEC iQ-F FX5 User's Manual (Application).
