Pattern introduction
– P-1: trigger received
– A1: Triggering again during the delay is invalid
– A2: Re-timing is triggered again during the delay
– A3: During the delay period, the relay is triggered again to reset and terminate the timing appliance, the Y time starts, and the relay is disconnected when the timing ends
– P-2: Receive a trigger signal, start X time, and continue when time ends
– P-3: Cycling switch mode
– A1: The relay is turned on after the power is turned on, and it is turned off when the timing is over, infinite loop
– A2: The relay is disconnected after the power is turned on, and it is connected after the timing is over, infinite loop
– P-4: After receiving the trigger signal, the relay will continue to be connected until the signal disappears and start timing. After the timing ends, the relay will be disconnected. If the trigger signal is received again during the delay period, the delay will be canceled until the signal disappears, and the timing will be restarted.
