Signal conditioning and scaling in SCADA systems - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to convert the raw sensor voltage to a temperature value.

SCADA systems

temperature = raw_voltage [1] 100

💡 Hint

Common Mistakes

Using division instead of multiplication

Adding instead of multiplying

Multiplying the raw voltage by 100 scales it to the temperature range.

2fill in blank

medium

Complete the code to offset the sensor reading by the zero calibration value.

SCADA systems

corrected_value = raw_reading [1] zero_offset

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

💡 Hint

Common Mistakes

Adding the offset instead of subtracting

Multiplying by the offset

Subtracting the zero offset removes the baseline error from the raw reading.

3fill in blank

hard

Fix the error in the scaling formula to convert ADC counts to voltage.

SCADA systems

voltage = adc_counts [1] (reference_voltage / max_adc_value)

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

💡 Hint

Common Mistakes

Using division instead of multiplication

Adding or subtracting instead of multiplying

Multiplying ADC counts by the ratio of reference voltage to max ADC value converts counts to voltage.

4fill in blank

hard

Fill both blanks to create a dictionary that maps sensor names to scaled values greater than 2.5.

SCADA systems

scaled_sensors = {name: value[1]2 for name, value in sensors.items() if value [2] 2.5}

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

💡 Hint

Common Mistakes

Using addition instead of power

Using '<' instead of '>' in condition

Using '**2' squares the value, and '> 2.5' filters values greater than 2.5.

5fill in blank

hard

Fill all three blanks to create a dictionary of sensor names in uppercase, their values, filtered by values greater than zero.

SCADA systems

result = { [1]: [2] for [3], v in sensor_data.items() if v > 0 }

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

💡 Hint

Common Mistakes

Using 'value' instead of 'v' for values

Not converting names to uppercase

The keys are sensor names in uppercase, values are sensor readings, and the loop variable is 'name'.
