Monolithic SCADA architecture in SCADA systems - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a monolithic SCADA system main process.

SCADA systems

def main_process():
    system_status = '[1]'
    print(f"System status: {system_status}")

💡 Hint

Common Mistakes

Choosing 'stopped' or 'idle' which means the system is not active.

The main process status should be set to 'running' to indicate the SCADA system is active.

medium

Complete the code to initialize the SCADA data collection loop.

SCADA systems

while system_status == 'running':
    data = collect_data()
    process_data(data)
    if [1]:
        break

💡 Hint

Common Mistakes

Using data conditions instead of system status to break the loop.

The loop should stop when the system status changes to 'stopped'.

hard

Fix the error in the SCADA system shutdown function.

SCADA systems

def shutdown_system():
    global system_status
    system_status = [1]
    print("System shutdown complete.")

A'stopped'

Bstopped

C"running"

D'running'

💡 Hint

Common Mistakes

Forgetting quotes around string literals.

The system status must be set to the string 'stopped' with quotes to update correctly.

4fill in blank

hard

Fill both blanks to create a dictionary mapping sensor names to their status in the SCADA system.

SCADA systems

sensor_status = { '[1]': 'active', '[2]': 'inactive' }

Drag options to blanks, or click blank then click option'

Atemperature_sensor

Bpressure_sensor

Chumidity_sensor

Dflow_sensor

💡 Hint

Common Mistakes

Using variable names without quotes or repeating the same sensor.

The dictionary keys should be sensor names as strings. 'temperature_sensor' and 'humidity_sensor' are common sensors.

5fill in blank

hard

Fill all three blanks to create a function that logs SCADA events with timestamp and message.

SCADA systems

def log_event([1], [2]):
    timestamp = get_current_time()
    log_entry = { '[3]': timestamp, 'message': [2] }
    save_log(log_entry)

Drag options to blanks, or click blank then click option'

Aevent_type

Bmessage

Ctime

Devent

💡 Hint

Common Mistakes

Mixing up parameter names or dictionary keys.

The function takes 'event_type' and 'message' as parameters. The log entry uses 'event' as the key for timestamp.
