Trend analysis and reporting in SCADA systems - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to start logging sensor data every minute.

SCADA systems

scheduler.schedule_task(sensor.read_data, interval=[1])

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

A60

B10

C120

D30

💡 Hint

Common Mistakes

Using 30 or 10 seconds instead of 60 seconds.

The interval is set in seconds. To log data every minute, use 60 seconds.

2fill in blank

medium

Complete the code to filter data points where temperature is above the threshold.

SCADA systems

filtered_data = [d for d in data if d.temperature [1] threshold]

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

A<

B>

C==

D<=

💡 Hint

Common Mistakes

Using '<' or '<=' which select lower temperatures.

We want data points where temperature is greater than the threshold.

3fill in blank

hard

Fix the error in the code to calculate the average value of sensor readings.

SCADA systems

average = sum(readings) [1] len(readings)

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

A-

B+

C*

D/

Attempts:

💡 Hint

Common Mistakes

Using '*' or '+' which do not compute average.

To find the average, divide the sum by the number of readings.

4fill in blank

hard

Fill both blanks to create a dictionary of sensor IDs and their latest values.

SCADA systems

latest_values = {sensor.[1]: sensor.[2] for sensor in sensors}

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

Aid

Bvalue

Ctimestamp

Dstatus

💡 Hint

Common Mistakes

Using timestamp or status instead of id or value.

The dictionary keys are sensor IDs and values are the latest sensor readings.

5fill in blank

hard

Fill all three blanks to filter and report sensors with values above threshold.

SCADA systems

report = {sensor.[1]: sensor.[2] for sensor in sensors if sensor.[3] > threshold}

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

Aid

Bvalue

Dstatus

Attempts:

3 left

💡 Hint

Common Mistakes

Using status or timestamp instead of value for filtering or reporting.

The report maps sensor IDs to their values, filtering those with values above the threshold.
