Batch Simulator Lesson 3

Similar to Lesson 1 and
Lesson 2 of Batch Simulator, but this time when the tank fills Level-Switch-hi makes Pumps 1&2 shut off

Then the heater heats up the process in the tank and when the thermostat indicated the Setpoint heat is reached heater shuts off and pump 3 turns on and empties the process from the tank.

Batch Simulator Lesson 2

Previous Lesson with the Batch simulator

Everything as before except this time while either Pump motor 1, 2, or 3 are running then the Mixer must be running.

Batch Simulator

This is the Batch simulator

• pumps 1 and 2 fill a tank and pump 3 empties the tank 
• Hi and low level switches turn pumps on and off
• when the tank gets full it automatically turns pumps 1 and 2 off and runs pump 3 to empty the tank
• When pump 1, 2, or 3 runs the Run Light turns on
• when the process is idle at any moment the Idle lite turns on 
• When the run light is engergized the idle lite turns off (that is when any of the pumps are running)
• Pump 1 and 2 pump at the same time
• The Bit is not a load, but something internal within the PLCs memory. In this case when pump 1 turns on the bit instruction is true making pump 2 true and running
• Rung 005 is for the full lite, but in this program the full light only lasts for just a moment since when the tank is full it automatically empties by running pump 3
