Custom Web Control

About Yield Funnel

The Yield Funnel is a high-performance Custom Web Control designed for industrial SCADA and HMI environments. It provides a sophisticated visualization of stage-by-stage throughput and material yield across consecutive process steps. By transforming complex production data into an intuitive funnel graphic, it allows operators to instantly identify where material loss occurs, ensuring maximum process efficiency in WinCC Unified and WinCC V8 environments.

Key Features

• Dynamic Process Visualization: Renders a multi-stage funnel based on the stages array, displaying absolute flow values and retention rates with smooth transitions.
• Intelligent Loss Detection: Automatically highlights critical material drops using the warningColor when the inter-stage reduction exceeds the defined lossWarningThreshold.
• Interactive Analytics: Features built-in tooltips for detailed phase analysis and supports the StageSelected event for deep-dive navigation.
• Comprehensive Header & Footer: Includes a dedicated header for the tagId and efficiencyLabel, plus an optional summary row for rawInflowLabel and maxLossLabel metrics.

Customization

The control offers 12 bindable properties for seamless integration. Engineers can define the visual identity using primaryColor and backgroundColor, while the showFooterSummary toggle allows for layout optimization based on screen real estate. The control also exposes methods like setStageValue and selectStage for advanced programmatic interaction via JavaScript.

Use Cases

This control is ideal for chemical processing, food and beverage production lines, water treatment facilities, and any manufacturing environment where monitoring material conversion and identifying bottleneck losses is critical for operational excellence.

Compatibility

Fully compatible with WinCC Unified (TIA Portal) and WinCC V8. The package includes all necessary manifest files for rapid deployment into your HMI engineering workflow.

💡 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.
