Practice - 5 Tasks

1fill in blank

easy

Complete the code to define the first step in ISA-18.2 alarm management lifecycle.

SCADA systems

alarm_lifecycle = ['[1]', 'Rationalization', 'Detailed Design', 'Implementation', 'Operation', 'Maintenance']

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

💡 Hint

Common Mistakes

Choosing a later step like 'Implementation' instead of the first step.

The first step in ISA-18.2 alarm management lifecycle is Identification, where alarms are identified and documented.

2fill in blank

medium

Complete the code to set the alarm priority according to ISA-18.2 standards.

SCADA systems

alarm_priority = '[1]'  # Options: Low, Medium, High, Critical

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

AMedium

BOptional

CInformational

DCritical

💡 Hint

Common Mistakes

Selecting 'Informational' which is not a priority level in ISA-18.2.

ISA-18.2 defines alarm priorities including Critical for the highest urgency alarms.

3fill in blank

hard

Fix the error in the alarm configuration code to comply with ISA-18.2.

SCADA systems

alarm_config = {'name': 'High Temp', 'priority': '[1]', 'enabled': True}

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

ACritical

BFalse

CLow

DNone

💡 Hint

Common Mistakes

Using boolean values instead of priority strings.

The priority must be a valid ISA-18.2 level like Critical, not a boolean or None.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that filters active alarms with priority above Medium.

SCADA systems

filtered_alarms = {alarm['id']: alarm for alarm in alarms if alarm['enabled'] == [1] and alarm['priority'] [2] 'Medium'}

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

ATrue

B>

C<

DFalse

💡 Hint

Common Mistakes

Using False for enabled or using < instead of > for priority comparison.

We filter alarms that are enabled (True) and have priority greater than (>) 'Medium'.

5fill in blank

hard

Fill all three blanks to create a dictionary of alarm names and their priorities for alarms that are active and critical.

SCADA systems

critical_alarms = {alarm['[1]']: alarm['[2]'] for alarm in alarms if alarm['enabled'] == [3] and alarm['priority'] == 'Critical'}

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

CTrue

💡 Hint

Common Mistakes

Using 'id' instead of 'name' for keys or using False for enabled.

The dictionary keys are alarm name, values are priority, filtered for enabled (True) and critical alarms.
