Answer the questions, in sequence, for the MCR program in Figure $9-29,$ assuming the program has just been entered and the PLC is placed in the RUN mode with all switches turned off. a$.$ Switches S$2$ and S$3$ are turned on$.$ Will outputs PL$1$ and PL$2$ come on$?$ Why? b$.$ With switches S$2$ and S$3$ still on$,$ switch S$1$ is turned on$.$ Will output PL$1$ or PL$2$ or both come on$?$ Why? c$.$ With switches S$2$ and S$3$ still on$,$ switch S$1$ is turned off. Will both outputs PL$1$ and PL$2$ deenergize? Why? d$.$ With all other switches off, switch S$6$ is turned on$.$ Will the timer time? Why? e$.$ With switch S$6$ still on$,$ switch S$5$ is turned on$.$ Will the timer time? Why? f$.$ With switch S$6$ still on$,$ switch S$5$ is turned off. What happens to the timer?
