摘要： A system and method for transferring data over an external transmission medium. A host computer is coupled to a device through a serial bus. A transfer object is configurable to encapsulate data transfer-related functionality, providing a generic interface for transmission of data over a variety of external transmission media and protocols. A user makes one or more transfer requests. Transfer objects corresponding to each request are built and linked together to form a sequential chain. The requests of the transfer objects are executed sequentially. If the current transfer object is the first in the chain, the request is executed on a current thread at passive level or higher, otherwise the request is executed on a system (kernel) thread at dispatch level. When a response to the request returns, control is returned to the current transfer object. The process is repeated until all transfer objects are processed.

摘要： A combination structure node is provided by a graphical programming development environment for use in a graphical program, where the combination structure node is operable to perform two or more control flow functions. For example, the combination structure node may be operable to perform two or more of: iteration, looping, conditional branching, sequencing, timed execution, event-driven execution, or other control flow functions. A user may include the combination structure node in a graphical program and associate a graphical code portion with the combination structure node. During execution of the graphical program, the combination structure node is operable to cause the associated graphical code portion to execute according to the two or more control flow functions performed by the combination structure node.

摘要： A system and method for executing a plurality of graphical code portions as a timed sequence is described. The graphical code portions may be included in a graphical program and configured with information specifying a sequential order of execution and execution timing information. During execution of the graphical program, the graphical code portions are executed sequentially in the sequential order and in accordance with the execution timing information. In one embodiment a timed sequence structure node may be utilized to specify the timed sequence. For example, the user may include the timed sequence structure node in the graphical program and associate the plurality of graphical code portions with the timed sequence structure node such that the timed sequence structure node species a sequential order of execution for the graphical code portions. The user may also configure the timed sequence structure node with execution timing information for one or more of the graphical code portions.

摘要： System and method for transferring data to a device using double buffered data transfers. A host computer system couples to a data acquisition device. The device includes a first read buffer and a second read buffer for storing output data received from the host computer. The device reads first data from the computer and stores it in the first read buffer. The first data is transferred out from the first read buffer while the device reads second data from the computer and stores it in the second read buffer. The second data is transferred out from the second read buffer (after the transfer of the first data) while the device reads third data from the host computer and stores the third data in the first read buffer. Thus, the data acquisition device successively reads data into one read buffer concurrently with transferring data out from the other buffer, respectively.

摘要： A system and method for executing a graphical program which has a plurality of timed loops, wherein the timed loops utilize timing sources that are related to or derived from each other. According to one embodiment of the method, a graphical program having a plurality of timed loops may be created. In one embodiment the timing sources may be related to each other according to tree hierarchy. Each of the loops in the graphical program may be associated with one of the timing sources. Thus the plurality of loops may be viewed as a group of loops that are grouped together due to the relationships among their respective timing sources. Execution of the graphical program may then begin. Execution of the loops may be delayed until every loop in the group is ready to execute. After every loop in the group is ready to execute, the timing sources for the various loops may be started. To satisfy the defined relationships among the timing sources, the timing sources may be started in an order based on their hierarchical relationship. Once the timing sources have been started, execution of the loops may be begun such that each loop executes based on its respective timing source, i.e., iterations of each loop are timed by its respective timing source.
摘要翻译：一种用于执行具有多个定时循环的图形程序的系统和方法，其中所述定时循环利用与彼此相关或相互导出的定时源。根据该方法的一个实施例，可以创建具有多个定时循环的图形程序。在一个实施例中，定时源可以根据树层次相互关联。图形程序中的每个循环可以与定时源之一相关联。因此，由于它们各自的定时源之间的关系，多个循环可以被视为被组合在一起的一组回路。然后开始执行图形程序。循环的执行可能会延迟，直到组中的每个循环都准备好执行。在组中的每个循环都准备好执行之后，可以开始各种循环的定时源。为了满足定时源之间的定义关系，定时源可以基于它们的分层关系按顺序开始。一旦定时源已经开始，可以开始循环的执行，使得每个循环基于其相应的定时源执行，即每个循环的迭代由其相应的定时源定时。

摘要： A system and method for enabling deterministic or time-triggered data exchange between a first graphical program and a second graphical program. A first variable is assigned to a first time slot in a network cycle. A first graphical program may be configured to write data to the first variable. A second graphical program may be configured to read data from the first variable. The first graphical program may be executed on a first computer system, where executing the first graphical program comprises writing data to the first variable. Writing data to the first variable may cause the data to be delivered over a network to a second computer system when the first time slot occurs. The second graphical program may be executed on the second computer system, where executing the second graphical program comprises reading from the first variable the data sent from the first computer system.
