1. In an automatic mixing operation the sequence of operation is as follows: When the start button is pressed fill the tank with Liquid B till it reaches X1 and then fill the tank with Liquid A till it reaches X2. Once the level of Liquid reaches X2, turn on the motor for another 20 seconds for mixing process. After the timer stops timing, empty the tank by opening the mixture outlet. X1 and X2 are capacitive proximity sensors and there are start, stop and emergency stop push buttons. XO START X1 STOP YO (Liquid A Inlet ) EMERGENCY STOP YI(Liquid B Inlet) Y2(Mixture Outlet) For the system explained above answer the following: a) Provide the Allocation List b) Draw the Grace and extract the grafcet equation c) Draw the Ladder Diagram

Automatic lawn sprinkler systems use a digital system to control the opening and closing of water valves. A sprinkler system usually supports several different zones such as the backyard, left side yard, right side yard, front yard etc. Only one zone's value can be opened at a time in order to remain enough water pressure in the sprinklers in that zone. suppose a sprinkler system supports up to 8 zones. Typically, a sprinker system is controlled by a small, inexpensive microprocessor executing a program that opens each value only at specific times of the day and for specific durations. suppose the microprocessor only has 4 output pins available to control the valves, not 8 outputs as required for the 8 zones. We can instead program the microprocessor to use 1 pin to indicate whether a valve should be opened, and use the 3 other pins to output the active zone (0,1....7) in binary. thus we need to design a combination circuit having 4 inputs, e, and a,b,c (the binary value of the active…
