In this exercise, you enter a timer instruction with a time delay of 10 seconds.
Two different types of timer status bits activate output pilot lights #0 and #1.
The first type, called a “timer timing” status bit turns on output #0 for 10
seconds. The second type, called a “done” status bit, turns on output #1 after
10 seconds.
The program that you will enter in this exercise will look like the one in the
