Alarm priority levels in SCADA systems - Mini Project: Build & Apply

Alarm priority levels

📖 Scenario: You are working with a SCADA system that monitors various sensors in a factory. Each alarm has a priority level that helps operators decide which alarms to address first.

🎯 Goal: Build a simple program that stores alarms with their priority levels, sets a threshold priority, filters alarms above that threshold, and displays them.

📋 What You'll Learn

Create a dictionary called alarms with exact alarm names and their priority levels

Create a variable called priority_threshold with an integer value

Use a dictionary comprehension to create a new dictionary high_priority_alarms with alarms having priority greater than priority_threshold

Print the high_priority_alarms dictionary

💡 Why This Matters

🌍 Real World

In SCADA systems, alarms with different priority levels help operators focus on the most critical issues first.

💼 Career

Understanding how to filter and manage alarm priorities is important for roles in industrial automation and system monitoring.

1

Create the alarms dictionary

Create a dictionary called alarms with these exact entries: 'Pump Failure': 5, 'Overheat': 8, 'Power Loss': 9, 'Low Pressure': 3, 'Sensor Fault': 4

SCADA systems

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

Need a hint?

Use curly braces {} to create a dictionary with keys and values separated by colons.

2

Set the priority threshold

Create a variable called priority_threshold and set it to the integer 5

SCADA systems

alarms = {'Pump Failure': 5, 'Overheat': 8, 'Power Loss': 9, 'Low Pressure': 3, 'Sensor Fault': 4}
# Set the priority threshold to 5
# Your code here

Need a hint?

Use a simple assignment to create the variable priority_threshold.

3

Filter high priority alarms

Use a dictionary comprehension to create a new dictionary called high_priority_alarms that includes only alarms from alarms with priority greater than priority_threshold

SCADA systems

alarms = {'Pump Failure': 5, 'Overheat': 8, 'Power Loss': 9, 'Low Pressure': 3, 'Sensor Fault': 4}
priority_threshold = 5
# Create high_priority_alarms dictionary using comprehension
# Your code here

Need a hint?

Use {key: value for key, value in dict.items() if condition} to filter the dictionary.

4

Display the high priority alarms

Write a print statement to display the high_priority_alarms dictionary

SCADA systems

alarms = {'Pump Failure': 5, 'Overheat': 8, 'Power Loss': 9, 'Low Pressure': 3, 'Sensor Fault': 4}
priority_threshold = 5
high_priority_alarms = {alarm: level for alarm, level in alarms.items() if level > priority_threshold}
# Print the high_priority_alarms dictionary
# Your code here

Need a hint?

Use print(high_priority_alarms) to show the filtered alarms.
