Question

18. Which one of the following Ladder nrogram can obtain an output from Output I when just input In 1 occurs? In i (a) (b) Jn 2 JR el (d) (c) Figure 6: Ladder diagram for Problem# 18 19. For the following Ladder program, there is an output from Output I when (a) There is an input to In2 and a momentary input to In 1. (b) There is only a momentary input to In 1 (c) There is only an input to In 2. (d) None of them. our choice is Raltery backoet Irs Output 1 Figure 7: Ladder diagram for Problem# 19 20. If a production sequence runs beyond a maximum continuous runtime, for example 10 seconds, conveyor belts might cause the work-piece carriers jammed. Therefore, an emergency-stop M EMSTOP input is included to stop all sequences of the assembly line when it happens, For the routing station (IMS9) with two conveyor belts, which of the following functions is correct to set the monitoring flag M NONALARM? (Notice that the flag M NONALARM is one of the inputs to M EMSTOP.)
