    The PLC im using only allows 6 inputs and 8 outputs,
    So I bought a few stuff to make make my security system.
    i never wrote it down so i got lost to a part to how i create a code.
    I got a buzzer (I1), LED(I2), a really small Detect switch (I3), Timer IC(I4), and 2 Momentary off -(on) push buttons (I5,6).

    I was figuring the detect switch gets activated (say someone walked in the house) the LED light switches on activating the timer for the buzzer if a certain order of the push button were not pressed correctly it will go off (siren) and you can try again if you get it right to shut off both LED and the buzzer and restart again.

    problem is the way the push button works to make a "code"
