SCADA Command Output: Energy Data Query

What is the output of the following SCADA system command that queries total energy consumption for the last hour?

SCADA systems

query_energy --start "2024-04-26T13:00:00Z" --end "2024-04-26T14:00:00Z" --metric total_consumption

A {"total_consumption_kWh": 1250}

B SyntaxError: missing argument for --metric

C {"total_consumption_kWh": 0}

D {"total_consumption_kWh": "error: invalid time range"}

💡 Hint

Check the time range and metric parameter correctness.

The command queries total energy consumption between the specified times and returns the numeric value in kWh.

❓ Configuration

Configuring Energy Reporting Interval

Which configuration snippet correctly sets the energy reporting interval to 15 minutes in a SCADA system YAML config?

A

reporting:
  interval: 900
  metric: energy_consumption

B

reporting:
  interval: "15 minutes"
  metric: energy_consumption

C

reporting:
  interval: 15m
  metric: energy_consumption

D

reporting:
  interval: 15
  metric: energy_consumption

💡 Hint

Look for the correct time format for interval in minutes.

The SCADA config expects interval in minutes with 'm' suffix for minutes.

Troubleshooting Missing Energy Data in Reports

A SCADA energy report shows zero values for all sensors despite active data collection. What is the most likely cause?

A The report file path is incorrect.

B The data collection service is stopped or crashed.

C The sensors are configured to report in a different unit.

D The report interval is set too short to collect data.

💡 Hint

Zero values usually mean no data was collected, not just a display issue.

If the data collection service is down, no data is gathered, resulting in zero values in reports.

🔀 Workflow

advanced

Energy Report Generation Workflow

Which sequence correctly describes the workflow to generate a daily energy consumption report in a SCADA system?

A 1,2,3,4

B 2,1,3,4

C 1,3,2,4

D 4,3,2,1

💡 Hint

Think about the logical order from data collection to report delivery.

Data must be collected first, then aggregated, then reported, then distributed.

Best Practice for Energy Data Backup in SCADA

What is the best practice to ensure energy consumption data is safely backed up in a SCADA system?

A Rely on cloud storage without local backups for cost savings.

B Manually copy data files weekly to a local USB drive.

C Store backups only on the same SCADA server to reduce latency.

D Schedule automated backups to a remote server daily with verification.

💡 Hint

Consider reliability, automation, and verification in backup strategies.

Automated remote backups with verification ensure data safety and availability.
