First use a VI Server Reference and a property node to obtain a reference to the front panel, and then use an additional property node to get an array of references to the front panel controls. Index this array of references through a For Loop. For each control, extract its name and ...
Therefore, the references need to be closed properly.Additional Information This message is most common if LabVIEW cannot allocate a block of memory large enough for an array. For example, a 2D array of double-precision floating-point numbers of size 2,000 by 2,000 elements uses approximately ...
Numeric, Boolean, string, or a 1D array of numeric, Boolean, or string values NoteValid numeric data types are Enum8, Enum16, Enum32, Enum64, I8, I16, I32, I64, U8, U16, U32, U64, DBL, SGL, or EXT. NI ROI indicators
Variable ReferencesAfter you add a shared variable to a LabVIEW project, you can drag the shared variable to the block diagram of a VI to read or write the shared variable, as shown in Figure 3. The read and write nodes on the diagram are called Shared Variable nodes....
较大的默认数据可能导致内存使用量增加和加载时间变慢。使用VI Analyzer工具包中的Array Default Values测试来识别默认数据不必要地增加内存使用的情况。避免为顶级VI创建一个单一的、单片的前面板。结合一些特性,如子面板控件和动态加载的VIs,如果使用得当,可以减少应用程序的内存使用量。
There are several components of this feature:1. The control Start Drag method (see Figure 13.130). This method starts a drag and drop operation using the control as the source. You get to specify Data, which is an array of clusters containing data name (a string) and drag data (a ...
LabVIEW has effective 2D (Charts and Graphs) and 3D visualization tools for data presentation. Graphs accept only array data. It plots all the received points at once. Charts attach received data to already existing points. When an array of points is wired to a chart or graph, LabVIEW assume...

3)相关的VI选用同样的连接块。这样便于相关的VI间进行连接,References,taskIDs,error clusters或者其他的通用终端能正确的连接在一起。 4)选择连接块样式不要超过16个终端。太多的终端可能看上去很有用,但他们在连接上会非常困难。如果有太多的数据需要传递的话,请使用簇。
