IEC 60870-5 protocol in SCADA systems - Mini Project: Build & Apply

Basic IEC 60870-5 Protocol Data Setup and Processing

📖 Scenario: You are working with a SCADA system that uses the IEC 60870-5 protocol to monitor electrical substations. Your task is to create a simple data structure representing some protocol data points, configure a threshold for alarm detection, process the data to find points exceeding the threshold, and finally display the alarms.

🎯 Goal: Build a small program that sets up IEC 60870-5 data points, configures an alarm threshold, filters data points exceeding this threshold, and prints the alarms detected.

📋 What You'll Learn

Create a dictionary called iec_data_points with exact keys and values representing point names and their measured values.

Add a variable called alarm_threshold with the exact value 75.

Use a list comprehension called alarms to select point names from iec_data_points where the value is greater than alarm_threshold.

Print the alarms list exactly as shown.

💡 Why This Matters

🌍 Real World

In real SCADA systems, IEC 60870-5 protocol data points represent measurements from electrical substations. Monitoring these points helps detect abnormal conditions like high current or temperature.

💼 Career

Understanding how to handle IEC 60870-5 data is important for roles in industrial automation, electrical grid monitoring, and SCADA system maintenance.

1

Create IEC 60870-5 Data Points

Create a dictionary called iec_data_points with these exact entries: 'Voltage': 70, 'Current': 80, 'Frequency': 60, 'Temperature': 85.

SCADA systems

# Create the dictionary iec_data_points with the specified entries
# Your code here

Need a hint?

Use curly braces to create a dictionary with the exact keys and values.

2

Set Alarm Threshold

Add a variable called alarm_threshold and set it to the integer value 75.

SCADA systems

iec_data_points = {'Voltage': 70, 'Current': 80, 'Frequency': 60, 'Temperature': 85}
# Set the alarm_threshold variable to 75
# Your code here

Need a hint?

Use a simple assignment to create the alarm_threshold variable.

3

Filter Alarms Using List Comprehension

Create a list called alarms using a list comprehension that includes the keys from iec_data_points where the value is greater than alarm_threshold. Use for point, value in iec_data_points.items() in the comprehension.

SCADA systems

iec_data_points = {'Voltage': 70, 'Current': 80, 'Frequency': 60, 'Temperature': 85}
alarm_threshold = 75
# Create the alarms list with points exceeding alarm_threshold
# Your code here

Need a hint?

Use a list comprehension with an if condition to filter points.

4

Print the Alarms List

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

SCADA systems

iec_data_points = {'Voltage': 70, 'Current': 80, 'Frequency': 60, 'Temperature': 85}
alarm_threshold = 75
alarms = [point for point, value in iec_data_points.items() if value > alarm_threshold]
# Print the alarms list
# Your code here

Need a hint?

Use print(alarms) to show the list of alarms.
