Study the ladder logic program in Figure 8-41, and answer the questions that follow:
a. What type of counter has been programmed?
b. What input address will cause the counter to increment?
c. What input address will cause the counter to decrement?
d. What input address will reset the counter to a count of zero?
e. When would output O:6/2 be energized?
f. Suppose the counter is first reset, and then input I:2/6 is actuated 15 times and input I:3/8 is actuated 5 times. What is the accumulated count value?
