118 -The setting value of the 16-bit up counter is 1 to 32767. As shown in the working process of the up counter in Figure C, after the normally open contact of X1 in the figure is turned on, C0 is reset, its corresponding bit storage unit is set to 0, the normally open contact of C0 is disconnected, and the normally closed contact point is turned on, and its current counter value is set to 0 at the same time.

120 120  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. When counting pulses again, the current value does not change until the reset input signal is turned on, and the current value of the counter is set to 0.
