Gantt Chart Export to File

This feature automatically converts modules, subprograms, and hierarchical processes in the DIATwin Gantt chart into a standardized hierarchical JSON data structure based on the timeline and operation records, ensuring complete consistency with the original visual presentation. This automation mechanism not only significantly replaces the tediousness and error risks of manually organizing flowcharts but also transforms simulated processes into traceable and analyzable digital assets, supporting cross-platform integration (such as MES, data analysis systems), allowing engineers to accurately decompose modules, compare performance, identify bottlenecks, and thus promote process optimization, truly achieving process transparency, intelligent management, and maximization of data value.

Operation Instructions:

1. Open DIATwin, import (_Example_ScrewMachine-1.dtl)
2. Switch to the Analysis tab, click on the Gantt chart function, click ADD
3. Add the process you want to observe, open the simulation function
4. After completing the simulation, click the "Export" function in the upper left corner.
5. The system reads the Gantt chart data of the current project (including modules, subprograms, hierarchical relationships).
6. The system converts the data into hierarchical JSON:
   • Includes Component information
   • Includes Process information (corresponding to Program Editor)
   • The JSON structure includes detailed information on Statements and Moves
7. Select the file storage location and press confirm to complete the file output.

Explanation Table for Gantt Chart Output Structure (GanttChart JSON Explanation)

Field Name	Data Type	Description
Fps	Float	The frame rate of the Gantt chart, determining the update frequency of the time coordinates and animations.
TimeUnit	String	The time unit used, defaulting to milliseconds ("ms").
PageName	String	The name of the Gantt chart page, for example, "Untitled".
GanttChartPage	Object	The main data object, containing the controller and its scheduling information.
ComponentList	Array	A list of controllers selected for recording, each corresponding to a row on the Gantt chart.

Explanation of ComponentList Fields

Field Name	Data Type	Description
ComponentUniqueName	String	The unique identifier name (UUID) of the controller.
DisplayName	String	The display name of the controller in the UI.
SubprogramList	Array	Describes the subprogram objects to be recorded under this controller.

Explanation of SubprogramList Fields

Field Name	Data Type	Description
Text	String	Describes the display name of the subprogram to be recorded in the UI, such as "Main", "Subprogram-XX".
Args	String	The parameter string passed, this field stores status descriptions or command details.
CommandList	Array	Describes the list of recorded Statements, which can recursively include sub-Statements (nested Statements structure). The top level records the first-level content of Statements (e.g., "Initial Pose", "while").

Explanation of CommandList Fields

Field Name	Data Type	Description
Text	String	Describes the command type under the specified Subprogram. For example, "Call", "PTP", "While", etc.
Args	String	The parameters passed to the command, formatted according to the command type definition. For example, the name of PTP, the name of the State, etc.
TimeList	Array	A list of time intervals indicating the start and end times of this command. Supports multiple executions (e.g., the time of procedures recorded repeatedly under while).
CommandList	Array	Nested commands; if the specified Text has subprograms, the program content is recorded.

Explanation of TimeList Fields

Field Name	Data Type	Description
BeginTime	Integer	The start execution time of the command (in units of TimeUnit, unit in milliseconds).
EndTime	Integer	The end execution time of the command (in units of TimeUnit, unit in milliseconds).
