Device a PLC ladder Diagram that perform automatically mixing of
two different chemicals in a tank:
a) When start button ‘s’ is pressed, chemical ‘A1’ enters the
tank via A1 inlet. When it fills up to 1m length of tank, inlet A1
closes.
b) When A1 inlet is closed, the chemical ‘A2’ starts pouring in
the tank through A2 inlet. A2 inlet is closed when the chemical
reaches 2m of tank’s length.
c) After the closing of A2 inlet, stirrer ‘S’ will be on for 50
seconds. To mix both chemicals.
d) After stopping stirrer, it allows the mixture to drain out
from ‘A3’ outlet. A3 outlet should be stopped after 100s.
Note: There should be an emergency stop button, when it is
pressed the whole system should be stopped.
