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 PL1l 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?
