FNC 54 – HSCR / High Speed Counter Reset
Outline
This instruction compares the value counted by a high speed counter with a specified value at each count, and
immediately resets an external output (Y) when both values become equivalent to each other.

Explanation of function and operation
1. 32-bit operation (DHSCR)
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 reset (set to OFF) regardless of the operation cycle. In this
instruction, the comparison processing is executed after the counting processing in the high speed counter.
Operation
When the present value of the high speed counter C255 changes (counts) from "99" to "100" or from "101" to "100",
Y010 is reset (output refresh).
When the present value of the high speed counter C255 changes (counts) from "99" to "100" or from "101" to "100",
Y010 is reset (output refresh).
