13.4 FNC 53 – HSCS / High Speed Counter Set
Outline
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.

2. Set data
3. Applicable devices
S1: "D.b" is available only in FX3U and FX3UC PLCs. However, index modifiers (V and Z) are not available.
S2: This function is supported only in FX
3U/FX3UC PLCs.
S3: When using the counter interrupt function in FX
3U/FX3UC PLCs, specify an interrupt pointer.
→ For counter interrupt using HSCS instruction, refer to Section 36.6.
Explanation of function and operation
1. 32-bit operation (DHSCS)
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.
Operand Type Description Data Type
Data to be compared with the current data value of a high-speed counter or word device
number.
32-bit binary
Device number of a high speed counter [C235 to C255] 32-bit binary
Bit device number to be set to ON when the compared two values are equivalent to each
other
