Cascader / Property Resolver: Update Rate 100Hz minimum

Q: What happens when conflicting properties are defined at the same hierarchy level?

The resolver uses timestamp-based conflict resolution (most recent definition wins) or applies machine-specific priority rules defined in the configuration schema. All conflicts are logged for audit purposes.

Q: Can this component handle dynamic property changes during machine operation?

Yes, it supports runtime property overrides with proper safety interlocks. Changes are validated against machine safety parameters before being applied to active systems.

Q: How does this integrate with existing PLC systems?

Through standardized industrial protocols like OPC UA and Modbus. The resolver provides a tag-based interface that maps directly to PLC memory addresses for seamless integration.

Component Specifications

Definition

The Cascader/Property Resolver is a software component within industrial styling engines that systematically processes hierarchical property data structures. It resolves conflicting or overlapping style definitions by applying precedence rules across multiple configuration layers (global, machine-type, individual machine, runtime). This component ensures consistent visual output across industrial equipment by calculating final property values through cascading inheritance logic, similar to CSS cascading but optimized for industrial control systems.

Working Principle

Operates on a hierarchical inheritance model where properties are defined at multiple levels (global defaults → machine category → specific machine → runtime overrides). The resolver processes these layers in reverse order, with higher-priority definitions overriding lower ones. It uses a directed acyclic graph (DAG) to manage dependencies between properties and ensures all constraints are satisfied before final values are passed to rendering subsystems.

Materials

Software component (no physical materials). Typically implemented in C++, Python, or Java for industrial control systems. Requires industrial-grade computing hardware with real-time operating system compatibility.
