SCADA system components overview in SCADA systems - Mini Project: Build & Apply

SCADA System Components Overview

📖 Scenario: You are working in a factory that uses a SCADA system to monitor and control machines. You want to organize the main parts of the SCADA system in a clear way so everyone can understand how it works.

🎯 Goal: Create a simple program that lists the main components of a SCADA system, adds a configuration setting for the number of sensors, then shows which components are active based on that setting, and finally prints the active components.

📋 What You'll Learn

Create a dictionary called scada_components with exact keys and values for main SCADA parts

Add a variable called sensor_count with the exact value 5

Use a for loop with variables component and status to find active components based on sensor_count

Print the list of active components exactly as shown

💡 Why This Matters

🌍 Real World

SCADA systems are used in factories and utilities to monitor and control equipment. Organizing components helps teams understand system parts and their roles.

💼 Career

Knowing SCADA components and how to manage their status is useful for roles in industrial automation, system monitoring, and maintenance.

1

Create SCADA components dictionary

Create a dictionary called scada_components with these exact entries: 'RTU': 'Remote Terminal Unit', 'PLC': 'Programmable Logic Controller', 'HMI': 'Human Machine Interface', 'SCADA Server': 'Central Server', 'Sensors': 'Field Sensors'.

SCADA systems

# Create the scada_components dictionary with exact entries
# Your code here

Need a hint?

Use curly braces {} to create the dictionary and separate each key-value pair with a comma.

2

Add sensor count configuration

Add a variable called sensor_count and set it to the exact value 5.

SCADA systems

scada_components = {
    'RTU': 'Remote Terminal Unit',
    'PLC': 'Programmable Logic Controller',
    'HMI': 'Human Machine Interface',
    'SCADA Server': 'Central Server',
    'Sensors': 'Field Sensors'
}
# Add sensor_count variable and set it to 5
# Your code here

Need a hint?

Just write sensor_count = 5 on a new line.

3

Find active components based on sensor count

Use a for loop with variables component and status to iterate over scada_components.items(). Create a list called active_components and add component to it only if component is not 'Sensors' or if sensor_count is greater than 0.

SCADA systems

scada_components = {
    'RTU': 'Remote Terminal Unit',
    'PLC': 'Programmable Logic Controller',
    'HMI': 'Human Machine Interface',
    'SCADA Server': 'Central Server',
    'Sensors': 'Field Sensors'
}
sensor_count = 5

# Create active_components list and add components based on sensor_count
# Your code here

Need a hint?

Start with an empty list. Use a for loop to check each component. Add it if conditions match.

4

Print active components

Write a print statement to display the active_components list exactly as shown.

SCADA systems

scada_components = {
    'RTU': 'Remote Terminal Unit',
    'PLC': 'Programmable Logic Controller',
    'HMI': 'Human Machine Interface',
    'SCADA Server': 'Central Server',
    'Sensors': 'Field Sensors'
}
sensor_count = 5

active_components = []
for component, status in scada_components.items():
    if component != 'Sensors' or sensor_count > 0:
        active_components.append(component)

# Print the active_components list
# Your code here

Need a hint?

Use print(active_components) to show the list.
