Daily and shift reports in SCADA systems - Mini Project: Build & Apply

Daily and Shift Reports

📖 Scenario: You work in a factory that uses a SCADA system to monitor machines. Every day, you need to create reports showing how many units each machine produced during different shifts.This helps the factory manager see which machines are working well and when.

🎯 Goal: Create a simple program that stores machine production data, sets a shift time, calculates total units produced during that shift, and then prints the report.

📋 What You'll Learn

Create a dictionary called machine_production with exact machine names and units produced

Create a variable called shift with the exact value 'morning'

Calculate total units produced during the shift using a loop

Print the total units produced in the shift with a clear message

💡 Why This Matters

🌍 Real World

Factories use SCADA systems to monitor machine output and generate reports for daily and shift production. This helps managers make decisions about maintenance and staffing.

💼 Career

Understanding how to collect, process, and report production data is key for roles in industrial automation, operations, and DevOps for manufacturing systems.

1

Create machine production data

Create a dictionary called machine_production with these exact entries: 'MachineA': 120, 'MachineB': 150, 'MachineC': 100

SCADA systems

# Create the machine_production dictionary with exact values
# Your code here

Hint

Use curly braces {} to create the dictionary and separate each machine and units with commas.

2

Set the shift variable

Create a variable called shift and set it to the string 'morning'

SCADA systems

machine_production = {'MachineA': 120, 'MachineB': 150, 'MachineC': 100}
# Create the shift variable and set it to 'morning'
# Your code here

Hint

Use simple assignment with the exact variable name shift and value 'morning'.

3

Calculate total units produced

Create a variable called total_units set to 0. Then use a for loop with variables machine and units to iterate over machine_production.items(). Inside the loop, add units to total_units

SCADA systems

machine_production = {'MachineA': 120, 'MachineB': 150, 'MachineC': 100}
shift = 'morning'
# Calculate total_units produced during the shift
# Your code here

Hint

Start with total_units = 0. Use a for loop with machine, units to get each machine's units. Add units to total_units inside the loop.

4

Print the total units report

Write a print statement that outputs exactly: "Total units produced during morning shift: 370"

SCADA systems

machine_production = {'MachineA': 120, 'MachineB': 150, 'MachineC': 100}
shift = 'morning'
total_units = 0
for machine, units in machine_production.items():
    total_units += units
# Print the total units produced during the shift
# Your code here

Hint

Use an f-string to include the shift and total_units variables in the printed message.

Practice

1. What is the main purpose of daily and shift reports in SCADA systems?

easy

A. To summarize system data for specific time periods

B. To control hardware devices directly

C. To update software automatically

D. To backup the entire system data

Solution

1. Step 1: Understand report function

   Daily and shift reports collect and summarize data over set time periods.

2. Step 2: Identify main goal

   The goal is to provide a clear summary of system performance and events during those periods.

3. Final Answer:

   To summarize system data for specific time periods -> Option A

4. Quick Check:

   Reports summarize data = D [OK]

Hint: Reports summarize data by time period, not control or backup [OK]

Common Mistakes:

• Confusing reports with control commands
• Thinking reports update software
• Assuming reports backup data

2. Which of the following is the correct way to specify a shift report for the night shift (10 PM to 6 AM) in a SCADA report configuration?

easy

A. shift_start = '22:00'; shift_end = '06:00'

B. shift_start = '06:00'; shift_end = '22:00'

C. shift_start = '10:00'; shift_end = '18:00'

D. shift_start = '00:00'; shift_end = '08:00'

Solution

1. Step 1: Identify night shift hours

   The night shift runs from 10 PM (22:00) to 6 AM (06:00).

2. Step 2: Match correct time format

   shift_start = '22:00'; shift_end = '06:00' correctly sets shift_start to '22:00' and shift_end to '06:00'.

3. Final Answer:

   shift_start = '22:00'; shift_end = '06:00' -> Option A

4. Quick Check:

   Night shift = 22:00 to 06:00 [OK]

Hint: Night shift starts at 22:00, ends at 06:00 [OK]

Common Mistakes:

• Mixing AM and PM times
• Using 12-hour format without AM/PM
• Swapping start and end times

3. Given this SCADA report script snippet:

data = [10, 20, 30, 40]
report_sum = sum(data)
report_avg = report_sum / len(data)
print(report_avg)

What will be the output?

medium

A. 20

B. 30

C. 25.0

D. SyntaxError

Solution

1. Step 1: Calculate sum of data

   Sum = 10 + 20 + 30 + 40 = 100.

2. Step 2: Calculate average

   Average = 100 / 4 = 25.0.

3. Final Answer:

   25.0 -> Option C

4. Quick Check:

   Average of [10,20,30,40] = 25.0 [OK]

Hint: Sum then divide by count to get average [OK]

Common Mistakes:

• Dividing by wrong length
• Adding incorrectly
• Confusing sum with average

4. You have this report configuration snippet:

shift_start = '22:00'
shift_end = '06:00'
if shift_start > shift_end:
    print('Invalid shift times')

Why does this code print 'Invalid shift times' even if the shift crosses midnight?

medium

A. Because shift_start and shift_end are not defined

B. Because string comparison does not handle time crossing midnight correctly

C. Because the if condition is always true

D. Because print statement is inside a comment

Solution

1. Step 1: Understand string comparison of times

   Comparing times as strings ('22:00' > '06:00') compares lexicographically, not by clock time.

2. Step 2: Recognize midnight crossing issue

   Times crossing midnight (e.g., '22:00' to '06:00') fail because '22:00' > '06:00' is true, but string comparison doesn't reflect time logic.

3. Final Answer:

   Because string comparison does not handle time crossing midnight correctly -> Option B

4. Quick Check:

   String compare ≠ time logic [OK]

Hint: String compare fails for times crossing midnight [OK]

Common Mistakes:

• Assuming string compare works for times
• Thinking condition is always true
• Ignoring midnight crossing logic

5. You want to generate a daily report that includes total production and average temperature for each shift. Which approach best combines these requirements in a SCADA report script?

hard

A. Calculate averages first, then total production for the whole day

B. Calculate total production only and ignore temperature

C. Generate separate reports for production and temperature without combining

D. Calculate totals and averages separately for each shift, then combine results in one report

Solution

1. Step 1: Identify report requirements

   Report must include total production and average temperature per shift.

2. Step 2: Choose method to combine data

   Calculating totals and averages separately per shift then combining into one report meets all requirements clearly.

3. Final Answer:

   Calculate totals and averages separately for each shift, then combine results in one report -> Option D

4. Quick Check:

   Combine metrics per shift in one report [OK]

Hint: Calculate each metric per shift, then combine [OK]

Common Mistakes:

• Ignoring temperature data
• Splitting reports unnecessarily
• Mixing daily and shift calculations incorrectly
