Problem No$.2$: $(35$ pts$.)$ please create using RSlogix

Design a PLC ladder logic program to control the operation of an automatic mixing

process using the following sequence:

A solenoid valve, VALVE$\_$IN$,$ automatically allows fluid in the mixing tank

$3$ seconds after a level switch, LEVEL$\_$EMPTY, detects when the tank is

empty.

VALVE$\_$IN is automatically de$-$energized as soon as a level switch,

LEVEL$\_$FULL, detects when the tank is full.

A mixer MOTOR is automatically energized for $10$ seconds after the tank is

full.

After the $10-$second mixing period the mixer MOTOR is automatically shut

down.

A second solenoid valve, VALVE$\_$OUT, is energized to drain the tank

immediately after the MOTOR shuts down.

VALVE$\_$OUT is automatically de$-$energized as soon as the level switch,

LEVEL$\_$EMPTY, detects when the tank is empty. The filling process must

start over at this point.

A master switch, ON$\_$OFF, is used to manually turn off the solenoid valves

and the mixer.

Hint: Latch$/$Unlatch both valves and motor with intermediate bits.

Program ON$\_$OFF on bit $0$ of the input module.

Program LEVEL$\_$EMPTY on bit $1$ of the input module.

Program LEVEL$\_$FULL on bit $2$ of the input module.

Program MOTOR on bit $0$ of the output module.

Program VALVE$\_$IN on bit $1$ of the output module.

Program VALVE$\_$OUT on bit $2$ of the output module.

Problem No$.3$: $(30$ pts$.)$

Design a PLC ladder logic program to control the operation of an alarm system using the

following sequence:

An ALARM must be energized and stay energized $($latched$)$ when a limit

SWITCH is activated once or when a motion SENSOR is activated three $(3)$

times within a space of $30$ seconds.

The ALARM can only be de$-$energized $($unlatched$)$ by pushing a hidden

normally$-$open momentary$-$contact BUTTON.

Hint: latch the timer with a sensor activation and use a count$-$up instruction to

count the number of sensor activations. Reset the count and unlatch the timer

if the timer is done.

Program SWITCH, SENSOR, and BUTTON using bits $0,1,$ and $2$ of the

input module respectively.

Program ALARM using bit $0$ of the output module.
