17: HIGH-SPEED COUNTER INSTRUCTIONS
17-4 USER’S MANUAL
Soft Reset Special Internal Relay M315
In addition to the hard reset using input I1, the high-speed counter current
value can be reset by turning special internal relay M315 on using another
input, output, or internal relay. M315, if used, must be programmed imme-
diately after the HSC1 instruction as shown on the right.
Multi-stage Data Setting
The data of comparison stages, preset values, and
comparison outputs are stored in consecutive data
registers starting with the data register designated by
source operand S1.
Store the quantity of preset stages in the first data
register.
In the next two data registers, store the upper and
lower digits of the preset value for the first stage.
In the fourth data register, store the destination of the
first-stage comparison output, using a numeric allo-
cation number of output or internal relay. See below.
Store data in these data registers before executing the
HSC1 instruction.
Preset Value
The preset value can be 1 through 4,294,967,295 (FFFF FFFFh), which is stored in two consecutive data registers. The
first data register stores the upper digits, and the next data register stores the lower digits. To enter a double-word value to
two consecutive data registers using the program loader, from the editor mode press the MON, D, data register number,
ADV, followed by the LOD/10 (decimal) or OUT/16 (hexadecimal), data register value, and keys. See page 3-16. If the
preset value is changed during high-speed counter operation, the high-speed counter remains unchanged for that cycle.
The change will be reflected in the next count cycle after resetting.
Allocation Numbers: Numeric and Symbolic
Use the numeric allocation numbers to specify the destination of the HSC1 comparison outputs.
Input Filter and Input Frequency
MICRO
3
has hard and soft filter functions. Only the hard filter works on high-speed counter instructions. The hard filter set-
tings affect the input response. See page 4-3. The maximum input frequency for the HSC1 instruction is 5 kHz.
