8-36 Using the Batch Simulator screen, write a program that will implement the following tank filling and mixing sequence.

• The start button is pressed to start input pump P1.
• After 100 gallons (one flowmeter pulse per gallon) input pump P1 stops automatically and the mixer motor starts.
• The mixer motor is automatically stopped after 30 seconds, and the input pump P1 is started.
• After an additional 60 gallons are pumped into the tank, the input pump stops and the mixer motor starts.
• The mixer motor is operated for 20 seconds and stops.
• The discharge pump P3 motor is started automatically and runs until the low-level sensor is actuated.
• The process stops.

Use the following addresses in developing the program:

• Start PB _ I:1/0
• Stop PB _ I:1/1
• Input Flowmeter _ I:1/5
• Low-Level Sensor _ I:1/3
• Mixer Motor _ O:2/0
• Input Pump P1 _ O:2/1
• Discharge Pump P3 _ O:2/3
• Internal Relay _ B3:0/0
• CTU _ C5:1
• CTU _ C5:2
• RTO _ T4:1
• RTO _ T4:2
