14 HIGH-SPEED COUNTER INSTRUCTION
14.1 High-speed Processing Instruction
Reset 32-bit data comparison
DHSCR
This instruction compares the value counted by a high-speed counter with a specified value, and immediately resets a bit
device if the two values are equivalent to each other, or resets the high speed counter. 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
• When the current value of a high-speed counter of the channel specified in (s2) becomes the comparison value (s1) (for
example, when the current value changes from "199" to "200" or from "201" to "200" if the comparison value is K200), the
bit device (d) is reset to OFF regardless of the scan time. For details, refer to
MELSEC iQ-F FX5 User's Manual
(Application).
