$4.$ Write Control TV Write a program to control a TV with a PLC$.$ The TV turns on when X$0$ is activated and latches on$.$ The TV is connected to Y$0.$ The program is to be written so that when the phone rights, the TV turns off. A special sensing circuit listens for the frequency of a ringing telephone. When detected, this device sends out a $24$V signal to input X$1$ to break the latch of output Y$0,$ turning off the TV$.5.$ A burglar alarm is activated by N$.$O$.$ switches placed on a door X$1,$ and window X$2.$ When the alarm is armed and a door or window is opened, the alarm will latch on$.$ The only way to turn off the alarm is to disable the power or to hit the reset button, X$0.$ To recap: X$0-$Reset X$1-$Door switch X$2-$Window switch Y$0-$Alarm power Consider the following questions: $(1)$ What happens if the window is opened? $(2)$ What happens if the door is opened? $(3)$ What happens if both the door and window are opened at the same time? $(4)$ How can the alarm be turned off? $(5)$ What could cause the alarm never to turn on$?(6)$ What could cause the alarm never to turn off? $(7)$ How could a burglar get by this system? $6.$ Microwave Oven A microwave oven has a start switch X$1,$ a cancel or stop switch X$0,$ and a door safety switch X$2.$ The oven will turn on $($Y$0$ on$)$ if the start and the safety switch are both closed and the stop switch is not activated. Consider the following questions: $(1)$ What happens to Y$0$ when X$1$ and X$2$ are activated and X$0$ is not activated? $(2)$ If the microwave is on and X$0$ is activated, what happens to Y$0?(3)$ If the microwave never turns on and the start switch is good, what could be wrong with X$0$ or X$2?(4)$ If the microwave does not turn off when the door is open, what could be wrong? $(5)$ If the microwave oven never turns on after activating X$1$ and the door is closed, what could be wrong? $7.$ Write Date or Not? Write a program to determine whether or not to date someone. The criteria are looks, money, family, job, and current to prior mental illness. Let the inputs be as follows: X$0-$Looks X$1-$Money X$2-$Family X$3-$Job X$4-$Mental illness Activating any of these inputs will mean they have good looks, money, a good family, a good job, a mental illness. The program should be written so that if the person has good looks and a good family and a good job, but not a mental illness, then the output will turn on$,$ Or if they have money, the output will turn on$.$ Let the output be Y$0.$ Connect to Y$0$ a $1$kohm resistor and a green LED. The status of this light indicates date worthiness. Have the output Y$0$ turn on if they are date worthy.
