X2 provides a counting input signal. When the reset input circuit of the counter is disconnected and the counting input circuit changes from disconnected to connected (that is, the rising edge of the counting pulse), the current value of counter C0 is increased by 1. After 10 count pulses, the current value of C0 is equal to the set value of 10, and its corresponding bit storage unit is set to 1, and the Y0 contact is turned on at this time.
