IIoT integration with SCADA in SCADA systems - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define the protocol used for IIoT data transfer in SCADA.

SCADA systems

protocol = "[1]"

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

AHTTP

BMQTT

CFTP

DSMTP

💡 Hint

Common Mistakes

Choosing HTTP which is heavier for IIoT devices.

MQTT is a lightweight messaging protocol commonly used for IIoT data transfer in SCADA systems.

medium

Complete the code to set the SCADA system to subscribe to the IIoT sensor topic.

SCADA systems

scada_client.subscribe("[1]")

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

Asensor/data

Bdevice/control

Csystem/logs

Dalerts/warnings

💡 Hint

Common Mistakes

Subscribing to control or log topics instead of sensor data.

The SCADA system subscribes to the 'sensor/data' topic to receive IIoT sensor readings.

3fill in blank

hard

Fix the error in the code to correctly parse JSON payload from IIoT device.

SCADA systems

import json
payload = '{"temperature": 22.5}'
data = json.[1](payload)

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

Adumps

Bload

Cdump

Dloads

💡 Hint

Common Mistakes

Using json.load which expects a file object.

json.loads() parses a JSON string into a Python dictionary.

4fill in blank

hard

Fill both blanks to filter IIoT sensor data with temperature above 25 and create a dictionary.

SCADA systems

filtered_data = {device_id: data[1] for device_id, data in sensors.items() if data['temperature'] [2] 25}

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

A.copy()

B==

C>

D!=

💡 Hint

Common Mistakes

Using '==' or '!=' instead of '>' for temperature comparison.

We use .copy() to copy the data dictionary and filter where temperature is greater than 25.

5fill in blank

hard

Fill all three blanks to create a dictionary of device names in uppercase with their status if status is 'active'.

SCADA systems

active_devices = [1]: [2] for [3], info in devices.items() if info['status'] == 'active'}

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

Adevice.upper()

Binfo['status']

Cdevice

Dinfo

💡 Hint

Common Mistakes

Using info instead of info['status'] as value.

The keys are device names in uppercase, values are their status, and the loop variable is device.
