Why Alarm Management Is Critical in SCADA Systems

📖 Scenario: You work as a technician in a factory that uses a SCADA system to monitor machines. The system shows alarms when something needs attention. You want to understand why managing these alarms well is very important.

🎯 Goal: Build a simple alarm list and learn how to identify critical alarms to manage them properly.

📋 What You'll Learn

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

Add a variable called critical_level to set the threshold for critical alarms

Use a for loop with variables alarm and level to find alarms with priority equal or above critical_level

Print the list of critical alarms exactly as shown

💡 Why This Matters

🌍 Real World

In factories and plants, SCADA systems monitor equipment and alert operators when something goes wrong. Managing alarms well helps prevent accidents and downtime.

💼 Career

Understanding alarm management is important for technicians and engineers who maintain industrial control systems to keep operations safe and efficient.

1

Create the alarm dictionary

Create a dictionary called alarms with these exact entries: 'Pump Failure': 5, 'High Temperature': 4, 'Low Pressure': 3, 'Power Loss': 5, 'Sensor Fault': 2

SCADA systems

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

Need a hint?

Use curly braces to create a dictionary with alarm names as keys and priority numbers as values.

2

Set the critical alarm level

Add a variable called critical_level and set it to 4 to mark alarms with priority 4 or higher as critical

SCADA systems

alarms = {'Pump Failure': 5, 'High Temperature': 4, 'Low Pressure': 3, 'Power Loss': 5, 'Sensor Fault': 2}
# Set the critical_level variable to 4
# Your code here

Need a hint?

Just create a variable and assign the number 4 to it.

3

Find critical alarms

Use a for loop with variables alarm and level to iterate over alarms.items(). Create a list called critical_alarms that includes alarm names with level greater than or equal to critical_level

SCADA systems

alarms = {'Pump Failure': 5, 'High Temperature': 4, 'Low Pressure': 3, 'Power Loss': 5, 'Sensor Fault': 2}
critical_level = 4
# Create the critical_alarms list using a for loop
# Your code here

Need a hint?

Start with an empty list, then add alarms that meet the priority condition inside the loop.

4

Display the critical alarms

Write a print statement to display the critical_alarms list exactly as it is

SCADA systems

alarms = {'Pump Failure': 5, 'High Temperature': 4, 'Low Pressure': 3, 'Power Loss': 5, 'Sensor Fault': 2}
critical_level = 4
critical_alarms = []
for alarm, level in alarms.items():
    if level >= critical_level:
        critical_alarms.append(alarm)
# Print the critical_alarms list
# Your code here

Need a hint?

Use print(critical_alarms) to show the list.
