Digital twin for process simulation in SCADA systems - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to initialize the digital twin model in the SCADA system.

SCADA systems

digital_twin = SCADA.create_model([1])

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

Asensor_data

Bprocess_parameters

Cuser_interface

💡 Hint

Common Mistakes

Using static parameters instead of live sensor data.

The digital twin model starts by using real-time sensor_data from the SCADA system to simulate the process accurately.

2fill in blank

medium

Complete the code to update the digital twin with new data.

SCADA systems

digital_twin.[1](new_sensor_values)

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

Breset

Cshutdown

Dinitialize

💡 Hint

Common Mistakes

Using 'initialize' which is for starting, not updating.

The method update_state refreshes the digital twin with the latest sensor values to keep the simulation current.

3fill in blank

hard

Fix the error in the code to simulate the process step.

SCADA systems

digital_twin.[1]()

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

Csimulate_step

Dsimulate

💡 Hint

Common Mistakes

Using 'simulate' which may run full simulation, not a step.

The correct method to advance the digital twin by one simulation step is simulate_step().

4fill in blank

hard

Fill both blanks to create a dictionary of sensor readings filtered by threshold.

SCADA systems

filtered_readings = {sensor: value for sensor, value in digital_twin.readings().items() if value [1] [2]

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

A>

B10

C<

D5

💡 Hint

Common Mistakes

Using '<' instead of '>' causing wrong filtering.

This code filters sensor readings to include only those with values greater than 10.

5fill in blank

hard

Fill all three blanks to create a dictionary of sensors with values above threshold and keys in uppercase.

SCADA systems

high_values = { [1]: value for [2], value in digital_twin.readings().items() if value [3] 15 }

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

Asensor.upper()

Bsensor

C>

D<

💡 Hint

Common Mistakes

Using '<' instead of '>' for filtering.

This dictionary comprehension creates keys as uppercase sensor names for readings greater than 15.
