programmable logic controllers (PLC) test
complete the assignment below:
Please draw a ladder program to control a motor. In this system, youhave two buttons: start button and stop button.
By default, the buttons have status 0. If you press the button, the status of the button becomes 1; if you release the button, the status becomes 0 again. The ladder program should have the following functionalities: 1) press the start button, the motor is running (using 1 to represent the running status);
2) release the start button, the motor keeps running until the stop button is pressed.

- Please refer to this textbook: “A. Silberschatz, P. B. Galvin and G. Gagne, “Operating System Principles,”7th Edition, John Wiley & Sons Inc., 2006.” And answer the following questions: Question4: If event A has a Lamport timestamp of 2 and event B has a Lamport timestamp of 3, you are certain that: A happened before B if the events took place on the same process. A happened before B regardless of the processes on which A and B took place. A and B are concurrent. B happened before A, regardless of the processes on which A and B took Placearrow_forwardThere is a strict restriction due to pandemic on the total number of customers who can be in a shop at any moment. The maximum number of customers in the shop can be 20 for this case. For this reason, design a system that counts the total number of customers available in the shop at any moment by writing C/C++ code.The design specifications are as follows: I) There are two sensors attached to the entrance and exit of the shop. When a person enters or leaves the shop, the related sensor provides a port interrupt. No two customers can enter or leave the shop together. II) There is an LED that indicates the total number of customers in the shop. If there are no customers, the LED will turn off. If there are 20 customers in the shop, the LED will be in its brightest form. The brightness of the LED will be adjusted linearly with respect to the customer number when the number of customers is between 0 and 20.arrow_forwardMake a flowchart using logic formulation INPUT: Subject, grade, passing PROCESS: Evaluate if grades conforms with process OUTPUT: Display if pass or failarrow_forward
