easy

Complete the code to set the IEC 60870-5 protocol port number.

SCADA systems

protocol_port = [1]

💡 Hint

Common Mistakes

Using HTTP port 8080 instead of IEC 60870-5 port.

The standard port for IEC 60870-5-104 protocol is 2404.

Complete the code to import the IEC 60870-5 protocol library in Python.

SCADA systems

💡 Hint

Common Mistakes

Using 'socket' which is generic, not protocol-specific.

The 'iec60870' library is used to handle IEC 60870-5 protocol in Python.

Fix the error in the code to create an IEC 60870-5 client connection.

SCADA systems

client = iec60870.Client('[1]', 2404)

💡 Hint

Common Mistakes

Including 'http://' in the IP address string.

The client needs a plain IP address without protocol prefix to connect properly.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension filtering IEC 60870-5 messages with priority above 3.

SCADA systems

filtered_msgs = {msg_id: msg for msg_id, msg in messages.items() if msg[1] [2] 3}

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

A.priority

B>

C<=

D.type

💡 Hint

Common Mistakes

Using '.type' instead of '.priority' or wrong comparison operator.

We access the 'priority' attribute and filter messages with priority greater than 3.

5fill in blank

hard

Fill all three blanks to build a dictionary of message IDs and their values where value is above 100.

SCADA systems

result = [1]: [2] for [3] in data.items() if value > 100

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

Amsg_id

Bvalue

Cmsg_id, value

Dmessage

💡 Hint

Common Mistakes

Using single variable 'message' instead of unpacking key and value.

The dictionary comprehension uses 'msg_id' as key, 'value' as value, and iterates over 'msg_id, value' pairs.
