1st scan
Store 2,700 in preset value 1 (D0004, D0005)
3rd scan
Detect the rising edge of M0000, turn on gate input (M8031)
Start high-speed counter counting in the END processing after the 3rd
scan is executed
2nd scan
Detect the falling edge of the initialize pulse, M0000 and M8032 turn on
Initialize the current value with the reset value in the END processing
after the 2nd scan is executed
Store 0 in the reset value (D8054, D8055)
Turn off gate input (M8031)

M8032 (reset input) is a special internal relay that stores the reset
value (D8054, D8055) in the current value (D8050, D8051).
When the current value becomes 2,700 pulses, comparison
output Q2 turns on
The timer starts and comparison output reset (M8030) turns on after
five seconds
Store 1 in the next preset value number (D0002)
In this example, Z-phase reset input is not used.
