Historian architecture overview in SCADA systems - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define the main component that collects data in a historian system.

SCADA systems

data_collector = [1]()

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

ADataLogger

BDataViewer

CDataCollector

DDataAnalyzer

💡 Hint

Common Mistakes

Choosing components that analyze or display data instead of collecting it.

The DataCollector is the main component responsible for gathering data from sensors or devices in a historian architecture.

2fill in blank

medium

Complete the code to specify the storage type used for long-term data in a historian.

SCADA systems

storage = [1]Storage()

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

BArchive

CRealTime

DCache

💡 Hint

Common Mistakes

Confusing temporary or cache storage with long-term archive storage.

ArchiveStorage is used for long-term storage of historical data in a historian system.

3fill in blank

hard

Fix the error in the code to correctly initialize the historian's data query interface.

SCADA systems

query_interface = Historian.[1]()

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

AQueryEngine

BDataCollector

CDataStorage

DDataViewer

💡 Hint

Common Mistakes

Using components meant for data collection or storage instead of querying.

The QueryEngine is the correct interface to query and retrieve data from the historian.

4fill in blank

hard

Fill both blanks to create a dictionary mapping components to their roles in historian architecture.

SCADA systems

components = {"collector": [1], "storage": [2]

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

A"DataCollector"

B"DataAnalyzer"

C"ArchiveStorage"

D"RealTimeProcessor"

💡 Hint

Common Mistakes

Mixing analysis or processing components with collection or storage roles.

The DataCollector collects data, and ArchiveStorage stores it long-term in historian systems.

5fill in blank

hard

Fill all three blanks to define a function that queries data, processes it, and returns results in historian architecture.

SCADA systems

def process_data():
    data = [1].query()
    processed = [2](data)
    return [3]

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

Aquery_interface

Banalyze_data

Cprocessed

Ddata_collector

💡 Hint

Common Mistakes

Using the wrong variable for querying or returning data.

The function queries data using query_interface, processes it with analyze_data, and returns the processed result.
