Study the ladder logic program in Figure 8-37 , and answer the questions that follow:

a. What type of counter has been programmed?

b. When would output O:2/0 be energized?

c. When would output O:2/1 be energized?

d. Suppose your accumulated value is 24 and you lose ac line power to the controller. When power is restored to your controller, what will your ac-cumulated value be?

e. Rung 4 goes true and while it is true, rung 1 goes through ?ve false-to-true transitions of rung conditions. What is the accumulated value of the counter after this sequence of events?

f. When will the count be incremented?

g. When will the count be reset
