ISA-18.2 alarm management standard in SCADA systems - Mini Project: Build & Apply

Implementing ISA-18.2 Alarm Management Standard in SCADA Systems

📖 Scenario: You work as a SCADA system operator in a manufacturing plant. Your task is to organize and manage alarms following the ISA-18.2 standard to improve safety and efficiency.

🎯 Goal: Build a simple alarm management setup that categorizes alarms, sets priority levels, and displays active alarms clearly, following ISA-18.2 principles.

📋 What You'll Learn

Create a dictionary called alarms with alarm names as keys and their status as values ('active' or 'inactive')

Add a configuration dictionary called alarm_priorities mapping alarm names to priority levels ('High', 'Medium', 'Low')

Write a loop to filter only active alarms and create a new dictionary active_alarms with their priorities

Print the active_alarms dictionary to display current active alarms with priorities

💡 Why This Matters

🌍 Real World

In industrial plants, managing alarms properly helps operators respond quickly to important issues, reducing downtime and improving safety.

💼 Career

Understanding ISA-18.2 alarm management is essential for SCADA operators, control engineers, and DevOps professionals working with industrial automation systems.

1

Create the initial alarm status dictionary

Create a dictionary called alarms with these exact entries: 'Pump Failure': 'active', 'High Temperature': 'inactive', 'Low Pressure': 'active', 'Power Loss': 'inactive'

SCADA systems

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

Need a hint?

Use curly braces to create a dictionary with the exact alarm names and their statuses.

2

Add alarm priority configuration

Create a dictionary called alarm_priorities with these exact entries: 'Pump Failure': 'High', 'High Temperature': 'Medium', 'Low Pressure': 'Low', 'Power Loss': 'High'

SCADA systems

alarms = {'Pump Failure': 'active', 'High Temperature': 'inactive', 'Low Pressure': 'active', 'Power Loss': 'inactive'}
# Create the alarm_priorities dictionary with exact entries
# Your code here

Need a hint?

Use a dictionary to map each alarm to its priority level exactly as shown.

3

Filter active alarms and map their priorities

Use a for loop with variables alarm and status to iterate over alarms.items(). Inside the loop, if status is 'active', add the alarm and its priority from alarm_priorities to a new dictionary called active_alarms

SCADA systems

alarms = {'Pump Failure': 'active', 'High Temperature': 'inactive', 'Low Pressure': 'active', 'Power Loss': 'inactive'}
alarm_priorities = {'Pump Failure': 'High', 'High Temperature': 'Medium', 'Low Pressure': 'Low', 'Power Loss': 'High'}
# Create active_alarms dictionary with active alarms and their priorities
# Your code here

Need a hint?

Use a for loop to check each alarm's status and add only active alarms to the new dictionary with their priority.

4

Display the active alarms with priorities

Write print(active_alarms) to display the dictionary of active alarms with their priority levels

SCADA systems

alarms = {'Pump Failure': 'active', 'High Temperature': 'inactive', 'Low Pressure': 'active', 'Power Loss': 'inactive'}
alarm_priorities = {'Pump Failure': 'High', 'High Temperature': 'Medium', 'Low Pressure': 'Low', 'Power Loss': 'High'}
active_alarms = {}
for alarm, status in alarms.items():
    if status == 'active':
        active_alarms[alarm] = alarm_priorities[alarm]
# Print the active_alarms dictionary
# Your code here

Need a hint?

Use print() to show the active alarms dictionary exactly.
