The current counter is decremented by one for each pulse on the count input (CD). The output is set if the CV is greater than or equal to the counter limit (PV). The output (QD) is set if the CV is less than or equal to zero. The value of the CV is reset to zero by a pulse on the reset input (R).
The value that the counter will count to or from is known as the counter period (depend on count-up or count-down).
When a timer receives a power on signal, its output will change state after a predetermined amount of time. When a start input signal is received, the timer will turn on, and when the preset timeframe is reached, the signal state of the output will change from 1 to 0.
The purpose of a retentive ON delay timer is to delay the ON time; if the input is turned off in the middle, the accumulator value will be resumed, and when the input is turned back on, it will begin running for the resumed value. If we close and open the VLC video player again, it will play video from the resumed position.
