Custom Web Control

About Maintenance Spare Parts Manager

The Maintenance Spare Parts Manager is a high-performance Custom Web Control designed for industrial SCADA and HMI environments. It provides a centralized, interactive inventory interface that allows operators to monitor stock levels, track storage locations, and manage material movements directly from the HMI screen. By integrating this control into WinCC Unified or WinCC V8, maintenance teams gain immediate visibility into critical component availability, reducing downtime caused by missing spares.

Key Features

• Dynamic Inventory Tracking: Displays a comprehensive list of parts with real-time stock level bars, minimum markers, and status classifications (In stock, Low, or Out).
• Interactive Stock Movements: When the allowMovements property is enabled, operators can perform Issue or Restock actions via a validated dialog, triggering the OnStockMovement event.
• Intelligent Header Analytics: The header automatically calculates and displays the number of parts currently below their minimum threshold using the belowMinimumLabel chip.
• Robust Validation: Built-in logic prevents invalid entries using the exceedsStockMessage and invalidQuantityMessage to ensure data integrity before writing to the lastMovement output property.

Customization

The control offers 25 adjustable properties for deep integration. Engineers can localize the entire interface using properties like partNumberHeader, inStockLabel, and confirmButtonText. The visual appearance is easily adjusted via the backgroundColor property, while the selectPart and clearSelection methods allow for external programmatic control from the HMI script engine.

Use Cases

This manager is ideal for automated warehouse kiosks, localized maintenance stations on the factory floor, and centralized inventory dashboards for plant managers who need to coordinate restocking schedules based on real-time consumption.

Compatibility

Fully compatible with WinCC Unified (TIA Portal) and WinCC V8. The control is designed to work seamlessly with PLC-backed JSON arrays and HMI tags.

💡 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, such as the movement output object. If you do not, the CWC will only be able to read the HMI tags and not write to them.
