digit 6

Q.No.04 It is required to design a system to control the parking system. This parking plot has total capacity of last_digit cars. Number of empty spots are displayed on the seven segment display outside the parking plot and which spots are available is to be indicated by LEDs as shown in Figure 02. A red LED should turn ON when all spots are occupied. 00 1 2 3 4 5 6 ax2 Total spots available Empty spots Figure 2 Evaluate the above scenario and answer the following solutions: a. Design a high level block diagram of the complete system and must include display system. b. Design PLC Ladder Logic Diagram for the given Scenario. Use this block to convert BCD counter output into BCD for display c. Analyze the circuit operation using timing diagram. Assume last_digit/2 cars are already present in the parking plot.
