Graphical Control Models for Unsupported Signal Type Code Generation

The patent introduces an intermediary mechanism (data storage object with identifier) that bridges the gap between unsupported signal types in the graphical model and the required data types in the control program. The data storage object acts as a mediator that stores variable information and enables the code generator to handle unsupported types through indirect reference rather than direct type recognition

The patent creates a copy mechanism where the data storage object contains an identifier that references the actual variable needed in the control program. Instead of directly representing the unsupported signal type, the system creates a surrogate data storage object that copies only the essential identification information, allowing the code generator to work with a simplified representation

The patent applies partial action by storing only the essential identifier information in the data storage object rather than complete type definitions. This partial representation is sufficient for code generation purposes, achieving the necessary accuracy without the overhead of complete type information, thus reducing modeling time while maintaining program generation accuracy

The patent performs preliminary action by pre-storing variable identifiers and basic information in the data storage object before the code generation process begins. This preliminary preparation allows the code generator to quickly retrieve and use the stored information without performing complex type analysis during code generation, thereby reducing overall processing time while ensuring accuracy
