This instruction compares a value counted by a high speed counter with a specified value, and immediately sets an
external output (Y) if the two values are equivalent each other.

→ For the counter interrupt using HSCS instruction, refer to Section 36.6.

S1: "D….b" is available only in FX

3U

 and FX

3UC

 PLCs. However, index modifiers (V and Z) are not available.

S2: This function is supported only in FX

 PLCs.

S3: When using the counter interrupt function in FX

3U

/FX

3UC

 PLCs, specify an interrupt pointer.

→ For counter interrupt using HSCS instruction, refer to Section 36.6.

When the current value of a high speed counter (C235 to C255) specified in 

 becomes the comparison value

[

+1, 

] (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 

 is set to ON without regard to the operation cycle.  This instruction is

executed after the counting processing in the high speed counter.
