    a tank is used to mix 2liquids.the control cct operates as follows;
    (A)-when the start button is pressed,solenoids A and B energize.this permits the two liquids to begin filling the tank.(B)-When the tank is filled,the floater switch trips.this de-energizes solenoids A and B and starts the motor used to mix the liquid together.(C)-the motor is permitted to run for one minute.after one minute has elapsed,the motor turns off and solenoid C energizes to drain the tank.(D)-when the tank is empty the float switch de-energizes solenoid C.(E)-A stop button can be used to stop the process anytime.(F)-if the motor becomes overloaded,the action of the entire cct will stop.(G)-once the cct has been energized,it will continue to operate until it ismanually stopped.

    ###pliz sirs/madams if someone can help me with the schematic diagram with the detailed sequence of operation WITH PLC programing to design a program used to control this process...//

    sounds like alot of work. A bit too much for a random person on a forum to put all together.
    People might help you get started though.

    For PLC programming, this is a bit new to me. If I have a PLC I could do it.
    Without it I am not so sure how to go about it.

    But with relays and time delays no problem
