The chart below shows a required set of step sequences with the same time interval between steps. Provide a ladder diagram and a comprehensive explanation as a solution for this chart by using two eight-bit shift registers (SFTO controls relays 50 to 57. SFT1 controls relays 60 to 66). The sequence is to have an initial start signal and thereafter can be free running. A reset control and timer to clock the shift registers must be provided.
