Objective: To write a program that uses one time with varying times for different functions, using the LD and OUT function.

Program a single timer (TMR) such that :

a. When SW1 is on, there is a 1 sec delay, then LED6 turns ON.

b. When SW2 is on, there is a 3 sec delay, then LED6 turns ON.

c. When SW3 is on, there is a 5 sec delay, then LED6 turns ON.

Program two Shift Registers (SR) and one timer (TMR) enabled by Switch 4.

a. The 1st Shift Register will turn the lights ON with the following timing (you cna only use one timer)

LED1, immediately.

LED2, after 2 seconds.

LED3, after 4 seconds.

LED4, after 3 seconds.

b. Pause for 4 seconds then turn the lights off using the second SR in reverse order (4,3,2,1), pause one second and go forward again. (You can only use one timer for both Shift Registers).

c. The process should work indefinietely.

PLEASE SHOW STEPS AND LADDER LOGIC FOR THE PROGRAM ABOVE PLEASE
