Application: Write a ladder logic program and design appropriate HMI screen to operate the following heat treatment application.

$-$ You will be using a Switch on the HMI to simulate the presence of the part.

$-$ The temperature sensor is an analog sensor that provides output voltage between $0$ V to $10$ V to indicate temperature between $0$ to $2000$ deg. F$.$ To simulate the temperature, you will be using an I$/$O Field to enter the voltage between $0$ to $10$ V $.$

$1.$ Operator places part in a fixture then pushes the Start button.

$2.$ When the process is operating System ON light should be green otherwise the light should be red.

$3.$ An inductive Heating coil heats rapidly to $1500$ deg. Fahrenheit.

$4.$ When the temperature reaches greater than $1500$; the coil turns OFF and a Valve opens which sprays water on the part for $10$ s to complete the heat treatment.

$5.$ Once treatment is completed, Process Complete light should be ON$.$

$6.$ Then the operator removes the part and the sequence can begin again.

$7.$ Note there must be a Part present or the sequence should not start.

$8.$ Process can be stopped at any time using Stop button.
