Create a PLC application that performs as follows: a. When SW1 is turned OFF the Auto mode is enabled and runs as follows: i. The lights will be OFF as long as the voltage signal is less than 2.5V. ii. Form 2.5V to 7.5V the intensity of the light will increase from 25% to 75% respectively. iii. Over 7.5V the lights will turn ON at 100% b. When SW1 is Turned ON the manual mode is enabled and runs as follows: i. PB1 is used to turn the lights ON (100% intensity) ii.
