In a chemical factory, a chemical is stored in three different tanks. A level sensor in each tank produces a positive input voltage (+24V) when the level of chemical in the tank drops below a specified point. Ladder logic will monitor the chemical level in each tank and indicate an alarm condition when the level in any two of the tanks drops below a specified point. Develop a Truth Table, the resulting Boolean Expression and ladder logic in its simplest form. Explain your method of Boolean simplification. Inputs Required: Tank 1 sensor Tank 2 sensor Tank 3 sensor (X0) (X1) (X2) Outputs Required: (YO) Alarm

Question
In a chemical factory, a chemical is stored in three different tanks. A level
sensor in each tank produces a positive input voltage (+24V) when the level of
chemical in the tank drops below a specified point. Ladder logic will monitor
the chemical level in each tank and indicate an alarm condition when the level
in any two of the tanks drops below a specified point.
Develop a Truth Table, the resulting Boolean Expression and ladder logic in
its simplest form. Explain your method of Boolean simplification.
Inputs Required:
Tank 1 sensor
Tank 2 sensor
(X0)
(X1)
(X2)
Tank 3 sensor
Outputs Required:
(YO)
Alarm
