Centrifugal pumps are used to drain material from both the tanks at the same time.
Height of storage tank is 5meters that is 500cm and the level which is to be maintained is 470cm.
Calculate necessary conversions and use registers to store data and to do arithmetic operations.
PLC Program
Here is PLC program to Drain Two Different Products from 2 Tanks, along with program explanation and
run time test cases.
