Custom Web Control

About Process Funnel

Process Funnel is a high-performance Custom Web Control designed for industrial SCADA and HMI applications. It provides a sophisticated multi-stage visualization of material flow, retention, and conversion rates across sequential production steps. By transforming raw process data into an intuitive funnel geometry, it allows operators to instantly identify throughput efficiency and material loss in complex manufacturing chains. Simply import it into your WinCC Unified (TIA Portal) or WinCC V8 project and bind its properties to PLC tags for real-time operational visibility.

Key Features

• Intelligent Bottleneck Detection: When the highlightBottleneck property is enabled, the control automatically identifies and visually flags the stage with the highest retention loss using the warningColor.
• Interactive Stage Inspection: Operators can click or touch specific funnel segments to trigger the OnStageSelect event, enabling detailed drill-downs into specific process phases.
• Dynamic Geometry: The stages array property allows for flexible definition of process steps, automatically calculating yield percentages and adjusting the funnel taper to reflect actual flow dynamics.
• Programmatic Control: Utilize the selectStage and clearSelection methods to synchronize the funnel visualization with other HMI elements or automated sequences.

Customization

The control is fully adaptable to your corporate design and process requirements. Engineers can configure the backgroundColor and accentColor to match existing dashboards, while the tagId and title properties ensure clear equipment identification in the header. The selectedStageId property allows for seamless two-way binding between the HMI and the visual state of the funnel.

Use Cases

Ideal for chemical processing, food and beverage production lines, water treatment facilities, and any discrete manufacturing environment where monitoring material conversion and identifying flow constraints is critical for OEE optimization.

Compatibility

Works with WinCC Unified (TIA Portal) and WinCC V8. Includes full documentation with installation instructions for both platforms.

💡 TIA Portal Reminder: Remember to uncheck the "Read only" option in TIA Portal when linking a tag to a property that needs to be written from the Custom Web Control. If you do not, the CWC will only be able to read the HMI tags and not write to them.
