16) Answer each of the following with reference to the overfill alarm program shown in the figure below. a. Assume that the vessel is filling and has reached the 300-lb point. State the status of each of the logic rungs (true or false) at this point. b. Assume that the vessel is filling and has reached the 480-lb point. State the value of the number stored in each of the following words at this point: (1) I:012 (2) N7:1 c. Assume that the vessel is filled to a weight of 502 lb. State the status of each of the logic rungs (true or false) for this condition. d. Assume that the vessel is filled to a weight of 510 lb. State the value of the number stored in each of the following words for this condition: (1) I:012 (2) N7:1 18 e. With the vessel filled to a weight of 510 lb, state the status of each of the logic rungs (true or false).

A (S1)-0- B (S2)-0 C (S3)-0- AB B BC B+C What is the Boolean equation for the given figure? ***************** The Boolean equation for the given figure is (Click to select) Note: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.

8) Answer the questions, in sequence, for the MCR program in the figure, assuming the program has just been entered and the PLC is placed in the RUN mode with all switches turned off a. Switches S2 and S3 are turned on. Will outputs PL1 and PL2 come on? Why? b. With switches S2 and S3 still on, switch S1 is turned on. Will output PL1 or PL2 or both come on? Why? c. With switches S2 and S3 still on, switch S1 is turned off. Will both outputs PL1 and PL2 deenergize? Why? d. With all other switches off, switch S6 is turned on. Will the timer time? Why? e. With switch S6 still on, switch S5 is turned on. Will the timer time? Why? f. With switch S6 still on, switch S5 is turned off. What happens to the timer? If the timer was an RTO type instead of a TON, what would happen to the accumulated value? 10 Inputs Ladder logic program Outputs L1 L2 S1 (MCR)- oo s1 PL1 S2 PL1 oo s2 2 PL2 oo S3 S3 PL2 3 oo S4 S4 PL2 oo S5 oo S6 (MCR) 5- S5 (MCH)- 6 S6 TON EN TIMER ON DELAY Timer Time base Preset...
