Control loop monitoring in SCADA systems - Mini Project: Build & Apply

Control Loop Monitoring

📖 Scenario: You work in a factory that uses a SCADA system to monitor control loops. Each control loop has a unique ID and a current value. You want to track which loops are operating within safe limits.

🎯 Goal: Build a simple program that stores control loop data, sets a safe operating threshold, identifies loops exceeding this threshold, and displays them.

📋 What You'll Learn

Create a dictionary called control_loops with these exact entries: 'Loop1': 45.2, 'Loop2': 78.5, 'Loop3': 62.0, 'Loop4': 88.1

Create a variable called threshold and set it to 70.0

Use a dictionary comprehension called alerts to select loops from control_loops where the value is greater than threshold

Print the alerts dictionary to display loops exceeding the threshold

💡 Why This Matters

🌍 Real World

Factories use control loop monitoring to keep machines running safely by tracking sensor values and alerting operators when values go beyond safe limits.

💼 Career

Understanding how to filter and monitor control data is key for SCADA operators and DevOps engineers working with industrial automation systems.

1

Create control loop data

Create a dictionary called control_loops with these exact entries: 'Loop1': 45.2, 'Loop2': 78.5, 'Loop3': 62.0, 'Loop4': 88.1

SCADA systems

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

Need a hint?

Use curly braces to create a dictionary with keys as loop names and values as their readings.

2

Set threshold value

Create a variable called threshold and set it to 70.0

SCADA systems

control_loops = {'Loop1': 45.2, 'Loop2': 78.5, 'Loop3': 62.0, 'Loop4': 88.1}
# Create the threshold variable and set it to 70.0
# Your code here

Need a hint?

Just assign the number 70.0 to a variable named threshold.

3

Identify loops exceeding threshold

Use a dictionary comprehension called alerts to select loops from control_loops where the value is greater than threshold

SCADA systems

control_loops = {'Loop1': 45.2, 'Loop2': 78.5, 'Loop3': 62.0, 'Loop4': 88.1}
threshold = 70.0
# Create alerts dictionary with loops having values > threshold
# Your code here

Need a hint?

Use a dictionary comprehension with for loop, value in control_loops.items() and an if condition.

4

Display alert loops

Print the alerts dictionary to display loops exceeding the threshold

SCADA systems

control_loops = {'Loop1': 45.2, 'Loop2': 78.5, 'Loop3': 62.0, 'Loop4': 88.1}
threshold = 70.0
alerts = {loop: value for loop, value in control_loops.items() if value > threshold}
# Print the alerts dictionary
# Your code here

Need a hint?

Use print(alerts) to show the dictionary.
