Engineers Easily Generate Code with LabVIEW State Diagram Toolkit

8/20/2003 - National Instruments announced the LabVIEW State Diagram Toolkit, code-generating software for LabVIEW 7 Express that helps engineers interactively design well-architected, maintainable applications. With this toolkit, engineers use state diagrams to easily build applications that perform at optimal execution speeds.

State diagrams visually represent an application's high-level functionality, making even large applications easy to interpret. Using the LabVIEW State Diagram Toolkit, engineers easily build state diagrams by dragging and dropping graphical representations of their application's states and transitions in a visual editing space. Engineers can include an unlimited number of states, define how the application transitions from one state to another and set the start and end states without programming. For example, an automotive engineer can easily draw out the functionality of a manual transmission using five states to represent the gears and the appropriate number of transitions to represent possible shifts between those gears. As an engineer creates a state diagram, the toolkit automatically generates corresponding LabVIEW code that serves as the application framework, significantly reducing development time.

To modify an application, engineers make code changes in a single area, unlike applications created from traditional state diagram frameworks that require code changes in many areas for each modification. The intuitive visual depiction of the application structure makes the application easy to follow, so even engineers who did not originally create the application can easily maintain it over time.
