Serial vs Ethernet communication in SCADA systems - Hands-On Comparison

Serial vs Ethernet Communication Setup in SCADA Systems

📋 What You'll Learn

💡 Why This Matters

🌍 Real World

SCADA systems often need to manage devices communicating over different protocols like Serial and Ethernet. Filtering devices by communication type helps in configuring and troubleshooting the network.

💼 Career

Understanding how to handle device communication settings and filter them is essential for SCADA technicians and engineers to maintain reliable industrial control systems.

1

Create the device list

Create a list called devices with these exact dictionaries: {'name': 'Sensor1', 'comm_type': 'Serial'}, {'name': 'Actuator1', 'comm_type': 'Ethernet'}, {'name': 'Controller1', 'comm_type': 'Ethernet'}

SCADA systems

# Create the devices list with exact entries
# Your code here

Need a hint?

Use a list with dictionaries. Each dictionary must have keys 'name' and 'comm_type' with exact values.

2

Set the communication filter

Create a variable called filter_type and set it to the string "Ethernet"

SCADA systems

devices = [
    {'name': 'Sensor1', 'comm_type': 'Serial'},
    {'name': 'Actuator1', 'comm_type': 'Ethernet'},
    {'name': 'Controller1', 'comm_type': 'Ethernet'}
]
# Create filter_type variable set to "Ethernet"
# Your code here

Need a hint?

Remember to use double quotes around Ethernet.

3

Filter Ethernet devices

Use a list comprehension to create a list called ethernet_devices that includes only devices from devices where comm_type equals filter_type

SCADA systems

devices = [
    {'name': 'Sensor1', 'comm_type': 'Serial'},
    {'name': 'Actuator1', 'comm_type': 'Ethernet'},
    {'name': 'Controller1', 'comm_type': 'Ethernet'}
]
filter_type = "Ethernet"
# Create ethernet_devices list with devices filtered by comm_type == filter_type
# Your code here

Need a hint?

Use a list comprehension with device for device in devices and an if condition.

4

Display the filtered devices

Write a print statement to display the ethernet_devices list

SCADA systems

devices = [
    {'name': 'Sensor1', 'comm_type': 'Serial'},
    {'name': 'Actuator1', 'comm_type': 'Ethernet'},
    {'name': 'Controller1', 'comm_type': 'Ethernet'}
]
filter_type = "Ethernet"
ethernet_devices = [device for device in devices if device['comm_type'] == filter_type]
# Print the ethernet_devices list
# Your code here

Need a hint?

Use print(ethernet_devices) to show the filtered list.
