Chapter 9, Problem 8RQ
Program Plan Intro
a.
Programmable Logic Controller (PLC):
- PLC is a specialized computer used in industrial segments to control machines and process.
- PLC is program that consists of a set of instructions which resembles the controlling functions needed to perform specific tasks.
- The function of PLC is similar to that of a relay and hence, in an industrial segment a relay is greatly replaced by a suitable PLC.
- When compared to general Personal Computer (PC), a PLC is available in small and tiny sizes.
- The basic architecture of a PLC consists of an input-output interface module and a small Central Processing Unit (CPU) that runs by controlling
programming language.
Explanation of Solution
b.
Practical uses for forcing functions:
- The force functions available in PLCs are used to accomplish forcing.
- Force function refers to a manual control function that is capable of overriding the current status of I/O from keyboard...
Explanation of Solution
c.
Need to exercise extreme care:
- Extreme care must be taken while using forcing function because incorrect usage of forcing functions can cause damage to both equipment and people surrounding the equipment...

Question3: (30 MARKS) Passenger Rail Agency for South Africa Train Scheduling System Problem Statement Design and implement a train scheduling system for Prasa railway network. The system should handle the following functionalities: 1. Scheduling trains: Allow the addition of train schedules, ensuring that no two trains use the same platform at the same time at any station. 2. Dynamic updates: Enable adding new train schedules and canceling existing ones. 3. Real-time simulation: Use multithreading to simulate the operation of trains (e.g., arriving, departing). 4. Data management: Use ArrayList to manage train schedules and platform assignments. Requirements 1. Add Train Schedule, Cancel Scheduled Train, View Train Schedules and Platform Management 2. Concurrency Handling with Multithreading i.e Use threads to simulate train operations,…

Question3:
Passenger Rail Agency for South Africa Train Scheduling System
Problem Statement
(30 MARKS)
Design and implement a train scheduling system for Prasa railway network. The system should
handle the following functionalities:
1. Scheduling trains: Allow the addition of train schedules, ensuring that no two trains use the
same platform at the same time at any station.
2. Dynamic updates: Enable adding new train schedules and canceling existing ones.
3. Real-time simulation: Use multithreading to simulate the operation of trains (e.g., arriving,
departing).
4. Data management: Use ArrayList to manage train schedules and platform assignments.
Requirements
1. Add Train Schedule, Cancel Scheduled Train, View Train Schedules and Platform
Management
2. Concurrency Handling with Multithreading i.e Use threads to simulate train operations,
Each train runs as a separate thread, simulating its arrival, departure, and travel status.
3. Use ArrayList to manage train schedules for each…

The JS file should the completion of the task, and all necessary testing, so that just loading the file will complete the task with enough different inputs to ensure it works. Even Numbers [3 marks] Create a function that determines if a provided number is even. Define an array of numbers, then on the array use the appropriate array iterator to determine if the array contains only even numbers using the function you defined. Output the results, and test with several arrays. Long Names [3 marks] Define an array of names. Use an iterator to retrieve a new array containing only the names longer then 12 characters.
