Description
This SCL function block, FB_EnergyConsumption, records energy consumption in kWh based on continuous power measurement in kW. Running in the Siemens TIA Portal, it calculates consumption per minute in 60-second cycles, totals daily, monthly, and total consumption, and triggers an alarm if a daily limit is exceeded. Manual resetting of daily and monthly consumption is integrated.

Note: All modules are designed exclusively as a learning and optimization basis and are not approved for live operation. System modules, in particular, must be finally tested and commissioned by qualified personnel before productive use.

How it works

  1. Cycle start every 60 s via IEC timer → Calculation Energy_Cycle = Power_kW × (1/60 h)
  2. Add Energy_Cycle to Consumption_Day, Consumption_Month and Consumption_Total
  3. Reset timer
  4. Reset_Day active → Consumption_Day = 0
  5. Reset_Month active → Consumption_Month = 0
  6. Consumption_Day > LimitAlarm → Alarm = TRUE; otherwise Alarm = FALSE

Technical details
• Inputs: LoggingStart, Power_kW, Reset_Day, Reset_Month, LimitAlarm
• Outputs: Alarm, Consumption_Day, Consumption_Month, Consumption_Total (kWh)
• IEC timer PT=T#60s for minute cycle
• Internal variables: Energy_Cycle, Consumption_Day, Consumption_Month, Consumption_Total
• Simple multiplication and summation; alarm via comparison with limit value alarm

Possible applications
• Consumption monitoring of machines and systems in production
• Energy dashboards in building management systems
• After-sales monitoring for retrofit projects
• Training scenarios for PLC-based energy management

compatibility
• Siemens S7-1200 & S7-1500
• TIA Portal V13 or higher; recommended V16+ for HMI display and PLCSIM
