TOTALIZER Block Documentation

Overview

The Totalizer block is used to calculate the accumulated value of a process signal over time—typically used for flow measurements, energy consumption, or any continuously increasing quantity.

When the Totalizer block icon is selected on the HMI, a detailed faceplate opens up, allowing users to view live process data, adjust parameters, and manage the totalizer reset.

Block Icon

Totalizer

The Totalizer block icon represents the cumulative total of a process value (e.g., flow). It provides essential information directly on the icon for at-a-glance monitoring.

  • Blue Color Area: Displays the tag number for identification.
  • TOTAL: Displays the calculated totalized value in real-time.

On Clicking the Totalizer block icon, the associated faceplate opens, providing detailed control and status parameters.

Faceplate Tab

Totalizer

  • PV (Process Value): Real-time incoming flow or signal value.
  • TOTAL: Accumulated total.
  • Correction Factor (C_Fac): A scaling factor to adjust measurements.
  • Reset Button: Resets the accumulated total to zero.
  • ByTime: Optional sampling time base for updating the totalizer.

Operator Actions

Action How to Perform Caution
Monitor Flow/Usage Watch the TOTAL field for real-time updates. None.
Reset Totalizer Press the RESET button on the faceplate. Use only when needed. Reset will erase current accumulated value.
Check Process Value Ensure PV shows realistic flow or input readings. Contact maintenance if values look wrong.

Important: Only reset the TOTAL when the batch or operation is complete.

Usage Notes

  • Ensure C_Fac is configured based on your measurement units (e.g., liters per second to cubic meters).
  • Set the ByTime parameter according to the sampling frequency or operational logic.
  • Use the RESET button with caution; it clears the current totalized data.
