Visualization Documentation – TOTALIZER Block

Usage of TOTALIZER Block through SCADA Template

The TOTALIZER block is used for real-time accumulation of any continuous process signal such as flow rate, energy consumption, or pulse count over time.
It is essential in batch tracking, consumption analytics, and process metering in TPW HMI systems.

When users click on the Totalizer icon on the HMI, a dedicated faceplate opens, allowing live monitoring, parameter tuning, and reset actions.

Integrating the Totalizer Block into Visualization steps are given below:

1. Open the Visualization Page

  • Open Your Codesys Project.
  • In CODESYS, navigate to your desired visualization (e.g., Totalizer_HMI).

2. Insert the Totalizer Block Icon from Scada_test visu page

  • Open the Visualization Toolbox Go to Current Project.
  • Drag or drop the Totalizer block icon to your Visualization page.
  • Or Just Copy the Totalizer Block Icon from the Scada_test visu page and Paste into your Visualization page.

    ✅ This ensures consistent design, layout, and logic handling across all visuals.

3. Bind Logic Block Reference

  • Select the inserted Totalizer block icon.
  • click on the block icon Properties tab open automatically → Properties.
  • Go to the References and Expand the references.
  • you will see bl_totalizer Expand that also.
  • set the path in front of the tagtotalizer_fp by Double clicking on empty space and select the required tag.
  • Build and run the project.
  • During runtime, confirm the value changing in totalizer block icon.

Totalizer Block Icon – Visualization Behavior

Totalizer

  • Blue Header → Displays the Tag/Name.
  • TOTAL → Live display of the accumulated value.

On Clicking the icon brings up the full faceplate interface Opens.

Totalizer Faceplate Overview

Totalizer

This faceplate allows viewing of real-time signal data, scaling factors, and reset capability.

Faceplate Parameters Details

Field Description
PV Real-time incoming process value (e.g., flow).
TOTAL Accumulated value (based on PV and time).
Correction Factor (C_Fac) Multiplier to scale the PV for proper engineering units.
ByTime (Optional) Time-based integration logic.
RESET Button Resets accumulated TOTAL to zero.

Operator Actions

Action How to Perform
Monitor Accumulation Watch TOTAL for live updates.
Reset Totalizer Press RESET on faceplate.
Check Live Input Ensure PV shows valid input flow/signal.

Usage Guidelines

  • Scaling: Use C_Fac to match real-world units (e.g., L/s to m³).
  • Timebase: Set ByTime if totalization is to occur at specific intervals.
  • Resetting: Use reset only after batch or operation completion.

Summary

The Totalizer block is a key visualization tool for tracking cumulative process values in real-time.
It supports accurate measurements, easy scaling, and secure resets through a clean, user-friendly interface.

✔️ Ideal for batch tracking, flow metering, and energy audits across industrial operations.
