Program an ON$-$delay timer with a retentive input switch and a momentary input switch.

Program the inputs in parallel.Place each bit on a separate rung with an output.Write down the function of each bit while the timer is timing and when it finishes.

Replace the ON$-$delay timer with an OFF$-$delay timer.

Leave the bits as you previously had them programmed; again, use a retentive input switch and a momentary.Describe the function of each bit; state any major differences.

Program a RTO timer with the associated bits to see how it differs from the previous two. $($Don$\text{'}$t forget the Reset for the RTO$).$

Program a circuit using two timers to flash a bit on for $1$ second then off for $1$ second.
