Color coding standards (ISA-101) in SCADA systems - Mini Project: Build & Apply

Implementing Color Coding Standards (ISA-101) in SCADA Systems

📖 Scenario: You are working as a SCADA system operator. To improve safety and clarity, you need to apply the ISA-101 color coding standards to your system's alarm display panel. This helps operators quickly understand alarm statuses by color.

🎯 Goal: Build a simple color coding setup for alarms using ISA-101 standards. You will create a data structure for alarms, define color codes for alarm states, apply the color coding logic, and display the final color-coded alarm list.

📋 What You'll Learn

Create a dictionary named alarms with specific alarm names and their states

Define a dictionary named color_codes mapping alarm states to ISA-101 colors

Use a dictionary comprehension to create a new dictionary colored_alarms that maps alarm names to their color codes

Print the colored_alarms dictionary to show the final color-coded alarms

💡 Why This Matters

🌍 Real World

In SCADA systems, color coding alarms by ISA-101 standards helps operators quickly understand the urgency and status of alarms, improving safety and response times.

💼 Career

Understanding and implementing ISA-101 color coding is essential for SCADA operators, engineers, and DevOps professionals working in industrial automation and control systems.

1

Create the initial alarm states dictionary

Create a dictionary called alarms with these exact entries: 'Pump Failure': 'Active', 'High Temperature': 'Acknowledged', 'Low Pressure': 'Inactive'

SCADA systems

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

Need a hint?

Use curly braces to create a dictionary with keys as alarm names and values as their states.

2

Define the ISA-101 color codes dictionary

Create a dictionary called color_codes with these exact entries: 'Active': 'Red', 'Acknowledged': 'Yellow', 'Inactive': 'Green'

SCADA systems

alarms = {'Pump Failure': 'Active', 'High Temperature': 'Acknowledged', 'Low Pressure': 'Inactive'}
# Create the color_codes dictionary with exact entries
# Your code here

Need a hint?

Map each alarm state to its ISA-101 color using a dictionary.

3

Apply color coding to alarms using dictionary comprehension

Use a dictionary comprehension to create a new dictionary called colored_alarms that maps each alarm name in alarms to its corresponding color from color_codes

SCADA systems

alarms = {'Pump Failure': 'Active', 'High Temperature': 'Acknowledged', 'Low Pressure': 'Inactive'}
color_codes = {'Active': 'Red', 'Acknowledged': 'Yellow', 'Inactive': 'Green'}
# Create colored_alarms dictionary using comprehension
# Your code here

Need a hint?

Use {alarm: color_codes[state] for alarm, state in alarms.items()} to map alarms to colors.

4

Display the color-coded alarms

Write a print statement to display the colored_alarms dictionary

SCADA systems

alarms = {'Pump Failure': 'Active', 'High Temperature': 'Acknowledged', 'Low Pressure': 'Inactive'}
color_codes = {'Active': 'Red', 'Acknowledged': 'Yellow', 'Inactive': 'Green'}
colored_alarms = {alarm: color_codes[state] for alarm, state in alarms.items()}
# Print the colored_alarms dictionary
# Your code here

Need a hint?

Use print(colored_alarms) to show the final color-coded alarms.
