Prepare an I/O connection diagram and ladder logic program for the hardwired automatic mixing process circuit shown in Figure 7-33. Enter the program into the PLC, and prove its operation. The operation of the process can be summarized as follows: Process is initiated by pressing the start pushbutton PB2. Solenoid A is energized to allow fluid to flow into the tank. Fluid flows in until the float switch is activated at the full position. Agitator motor is started and operates for 5 minutes and then stops. Solenoid B is energized to empty the tank. When the float switch is activated at the empty position, the process stops and is placed in the ready position for the next manual start.
