6. Using a TON, TOF, or both construct a ladder diagram for the following scenario: a. A light OUT_1 should turn "ON" when normally close pushbutton IN_1 is momentarily pressed. The light should remain "ON" for 5 seconds and then turn "OFF". b. A second light OUT_2 will turn "ON" for 8 seconds right after the first light OUT_1 turns "OFF". It should remain "ON" indefinitely. Normally open pushbutton IN_3 resets the timers. (hint: Use DN to control timer) Design the ladder diagram to simulate this process. (student's work maybe handwritten)
