Demonstate the ability to use subroutines-math functions

Reference no: EM13252228

Purpose Demonstate the ability to use subroutines, math functions, and comparisons by simulating an HVAC control system Write a ladder program to accomplish the following

1- Provide all appropriate documentation including system design, memory map, process logic all I/O and rungs must be clear through comments The are no external field devices to sense temperature therefore

2- Create a simulated heat source using the green push button (1 push of a button = 1 degree higher)

3- Create a simulated cooling source using the red push button (1 push of a button = 1 degree lower)

4- Create a heating mode (the unit will only turn on the heater when TS1 is ON)

5- Create a cooling mode (the unit will only turn on the AC when TS1 is OFF)

6- Create a register to store the current room temperature at 70 degrees

7- Create 2 registers that contain an upper and lower temperature set point of 65 and 75 When the upper set point is reached (based on the internal simulated heating and cooling)

8- Turn on the AC (O:0/0) for ten seconds (only in cooling mode)

9- After ten seconds turn off the A/C and change the room temperature to 70 degrees simulating the room has cooled by 5 degrees When the lower set point is reached (based on the internal simulated heating and cooling)

10- Turn on the heater (O:0/1) for ten seconds (only in heating mode)

11- After ten seconds turn off the heater and change the room temperature to 70 degrees simulating the room has heated by 5 degree

12- Create an HVAC on/off mode In the off mode turn on the red light and the A/C and Heater will not function regardless of the temperature In the on mode turn on the yellow light and the unit should function.
