Analog vs digital data points in SCADA systems - Interactive Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define an analog data point in a SCADA system.

SCADA systems

analog_point = {'type': '[1]', 'value': 3.3}

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

💡 Hint

Common Mistakes

Choosing 'digital' instead of 'analog' for continuous data.

An analog data point represents continuous values like voltage or temperature, so the type should be 'analog'.

2fill in blank

medium

Complete the code to define a digital data point with a boolean value.

SCADA systems

digital_point = {'type': 'digital', 'value': [1]

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

ATrue

B3.3

C5

D'ON'

💡 Hint

Common Mistakes

Using numeric values for digital data points.

Digital data points typically use boolean values like True or False to represent ON/OFF states.

3fill in blank

hard

Fix the error in the code to correctly represent a digital data point.

SCADA systems

point = {'type': 'digital', 'value': [1]

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

A3.14

B2.7

CFalse

D'OFF'

💡 Hint

Common Mistakes

Using strings or numbers instead of boolean for digital points.

Digital data points should have boolean values like False, not numeric or string values.

4fill in blank

hard

Fill both blanks to create a dictionary for an analog data point with a float value.

SCADA systems

data_point = {'type': '[1]', 'value': [2]

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

Bdigital

C3.7

DTrue

💡 Hint

Common Mistakes

Mixing digital type with float value.

The type must be 'analog' and the value a float like 3.7 for an analog data point.

5fill in blank

hard

Fill all three blanks to create a list of mixed data points with correct types and values.

SCADA systems

points = [
  {'type': '[1]', 'value': [2],
  {'type': 'digital', 'value': [3]
]

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

💡 Hint

Common Mistakes

Assigning boolean to analog or float to digital incorrectly.

The first point is analog with a float value 5.5, the second is digital with a boolean False value.
