A system and method for creating and using type generic graphical programs. The method may include storing a first graphical program on a memory medium. The first graphical program may have been created based on user input. The first graphical program may include a plurality of nodes and interconnections between the nodes, and the plurality of nodes and interconnections between the nodes may be type generic. User input may be received specifying one or more data types of at least one input and/or at least one output of the first graphical program. The data types may be associated with the first graphical program in response to said user input specifying the one or more data types.

Type generic graphical programming

System and method for analyzing a graphical program. A graphical program is provided that includes a plurality of interconnected nodes that visually indicate functionality of the program. The graphical program includes a plurality of block diagrams arranged in a hierarchical manner, including a top-level block diagram and one or more sub-block diagrams, where each block diagram includes a respective subset of the plurality of interconnected nodes. At least one of the block diagrams includes a node that includes at least one of the sub-block diagrams. When a block diagram executes, all the respective nodes of the block diagram execute. Each node in the plurality of interconnected nodes is configured to provide graphical code coverage information when executed. The graphical program is executed, thereby generating graphical code coverage information for the graphical program indicating which nodes executed, which is then stored.

Graphical program code coverage

System and method for implicit downcasting at compile time in a data flow program. A first data flow function in an object-oriented dataflow program is identified, where the first function includes an input of a parent data type and an output of the parent data type. The first function is analyzed to determine if the output preserves the run-time data type of the input. A second dataflow function in the object-oriented data flow program is identified, where the second function includes a program element that calls the first function, passing an input parameter of a child data type of the parent data type as input. If the analysis determines that an output parameter returned by the output of the first function will always be of the child data type, the program element is automatically configured at compile time to always downcast the output parameter from the parent data type to the child data type at run-time.

Creating and using configuration diagrams for configuring distributed systems. The methods described herein may be used for various types of operations in configuring distributed systems, including creating programs, managing programs in the distributed system, deploying programs to various distributed devices, configuring remote execution or inter-operation of distributed programs, and executing distributed applications. Embodiments of the invention utilize graphical iconic-based techniques for performing the above operations. The configuration diagram may include device icons which represent devices and program icons which represent programs. Device icons and program icons may be associated with each other to accomplish various program creation and deployment operations. Device icons and program icons may also interact with graphical program nodes or icons. Context sensitive device connections and/or program connections are displayed. An asynchronous data flow node may be used to facilitate asynchronous data flow between two graphical programs. The distributed system may also support distributed graphical debugging.

System and method for including an in-place structure in a graphical program. Input including the structure in the graphical program may be received, where the structure is displayed in the graphical program. At least one graphical program node may be associated with the structure. The at least one graphical program node may be executable to manipulate at least one of a first element or a second element. The structure may specify that data memory of the first element is useable as the data memory of the second element in the graphical program. The structure may be usable by a development environment to reduce memory usage of the graphical program during execution.

In-place structure in a graphical program

System and method for deterministic modification of global variables in a graphical program. Input including the structure in the graphical program may be received, where the structure is displayed in the graphical program. At least one graphical program node is associated with the structure. The at least one graphical program node may be executable to modify the value of a global variable. During execution of the graphical program the structure ensures deterministic modification of values of the global variable.

System and method for creating a graphical program that uses multiple models of computation (MoC). A first plurality of graphical program elements is assembled in a graphical program in response to first input, where the assembled first plurality of graphical program elements have a first MoC. A structure is displayed in the graphical program indicating use of a second MoC for graphical program elements comprised within the interior of the structure. A second plurality of graphical program elements is assembled within the structure in response to second input, where the assembled second plurality of graphical program elements have the second MoC. The graphical program is executable to perform a function, for example, by executing the assembled first plurality of graphical program elements in accordance with the first model of computation, and executing the assembled second plurality of graphical program elements in accordance with the second model of computation.

System and method for creating, configuring, representing, and using variables in programs. A graphical user interface (GUI) may be displayed in response to user input requesting creation and/or configuration of a variable for use in or comprised in one or more programs, e.g., on various devices. User input is received to the GUI configuring attributes of the variable, including: name, data type, and/or scope (e.g., local, global, or network). The configured attributes are stored and optionally displayed, e.g., in a resource tree, and the variable in each of the programs updated in accordance with the configured attributes. When at least one of the programs is incompatible with the configured variable, an error condition may be indicated, e.g., by providing information relating to portions of the program that are incompatible with the configured variable. The program may be modified in response to user input for compatibility with the configured variable.
