Figure.03 shows a simple diagram of automated door control. The door operate as follows: XO(Infrared Sensor. ) X2(Opening Limit Switch) X1(Closing Limit Switch) X2(Opening Limit Switch) YO(Open the door) Y1(Close the door) Figure 3 When someone enters the infrared sensing field, opening motor starts working to open the door automatically till the door touches the opening limit switch . If the door touches the opening limit switch for 10 sec and nobody enters the sensing field, the closing motor starts working to close the door automatically till the closing limit switch touched together. Stop the closing action immediately if someone enters the sensing field during the door closing process. Evaluate the above scenario and answer the following solutions: a. Identify the inputs and outputs and draw a high level block diagram of the complete system, use PLC as your main controller. b. Draw the PLC ladder logic for the given scenario. [7 + 18 Marks]
