Visualization Documentation – SHIFT_TOTALIZER Block

Usage of SHIFT_TOTALIZER Block through SCADA Template

The SHIFT_TOTALIZER block is used to measure and accumulate flow totals across operator shifts (A, B, C) and daily summaries.
It is vital in systems requiring shift-wise monitoring of consumption or production like utilities, batching, or continuous processes.

This block is implemented as a standard faceplate component, built using CODESYS visualization templates.
The icon is available inside the Visu_page for reuse across different visualization pages.

Integrating the SHIFT_TOTALIZER Block into Visualization

1. Open Your Target Visualization Page

  • Open your CODESYS project.
  • Navigate to the HMI screen for flow monitoring or shift reporting (e.g., Shift_Monitoring, Flow_Analysis).

2. Insert the Shift_Totalizer Block Icon from Scada_test Visu Page

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

✅ Enables consistent and pre-designed monitoring UI for shift-based totalization.

  • Select the inserted Shift 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_shift_totalizer Expand that also.
  • set the path in front of the tagshift_totalizer_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.

SHIFT_TOTALIZER Icon – Visualization Behavior

No. Visual Element Description
1 Tag Number Field Visible in blue—identifies the process stream
2 TOTAL Value Real-time cumulative totalizer value shown clearly

🔄 Clicking the icon opens the detailed faceplate interface.

SHIFT_TOTALIZER Faceplate Overview

Clicking the icon opens a dedicated faceplate allowing live value viewing, shift tracking, and reset control.

Faceplate Fields and Functionality

Field Description
Tag Number Shown in blue for easy operator recognition
Flow Current flow/process value in engineering units
C_Fac Correction factor (scales Flow for accurate totalization)
ByTime Time base (SEC, MIN, or HOUR) for converting flow into totals
TOTAL Cumulative total for the current measurement cycle
A_Shift Total value accumulated during Shift A
B_Shift Total value accumulated during Shift B
C_Shift Total value accumulated during Shift C
T_Total Sum of all shifts for Today
Y_A_Shift Yesterday’s Shift A total
Y_B_Shift Yesterday’s Shift B total
Y_C_Shift Yesterday’s Shift C total
Y_Total Sum of all shifts for Yesterday
RESET Button Clears all totals (TOTAL, shift, today/yesterday) – use with proper permission

Operating Behavior by Role

User Role Permissions
Operator View current flow and all totalizer values (read-only)
Engineer Modify C_Fac, set ByTime, validate shift logic
Supervisor Authorized to press RESET and reinitialize all totals

⚠️ Only supervisors or engineers should reset total values during shift changes or planned maintenance.

How Shift Logic Works

  • Shift windows (e.g., A: 06:00–14:00, B: 14:00–22:00, C: 22:00–06:00) are defined in logic.
  • When system time crosses shift boundary:
  • Current shift total is moved to yesterday.
  • A new counter begins for the new shift.
  • Resetting all totals does not alter the shift timing logic.

Best Practices for SHIFT_TOTALIZER

  • Verify that C_Fac is configured per flow transmitter calibration.
  • Choose ByTime to match your flow signal unit (e.g., per sec/min/hr).
  • Use totals comparison (Today vs Yesterday) for production validation.
  • Always backup totals before performing a RESET.

Visual Summary

Visual Field Real-Time Behavior
TOTAL Shows live totalization update
A/B/C_Shift Accumulates totals for each operator shift
T_Total / Y_Total Daily and yesterday totals to aid in historical comparison

Security and Access Control

Role Access Type
Operator Monitor only
Engineer Configure correction/time base
Supervisor Reset capability and full faceplate access

Summary

The SHIFT_TOTALIZER block enhances process monitoring by enabling shift-wise accountability, total tracking, and historical comparison.
It integrates seamlessly into SCADA for operators, engineers, and supervisors to visualize and control flow totals.

✅ Real-time totals for A, B, and C shifts
✅ Separate Today and Yesterday values
✅ Faceplate with RESET, correction, and scaling
✅ Easy to link and reuse with Visu_page icon template
✅ Ideal for flow measurement, batching, and production lines

A must-have for processes where shift-wise performance tracking and historical audit is essential.
