:信号操作Express VI,对信号进行操作和对数据作类型转换,如Merge Signal(合并信号)、Split Signal(拆分信号)、Select Signal(选择信号)、Convert from Dynamic Data Type(从动态数据转换)、Convert to Dynamic Data Type(转换成动态数据)等。 :所有函数,包括函数模板中所有函数。 :结构子模板,用来设计程序的顺序、分...
error(return value)、cardNumber和channel都是值传递的参数,“Type”选择Numeric,“Data type”选择Unsigned 16-bit Interger,“Pass”选择Value;voltage是指向F64类型数据的指针,“Type”选择Numeric,“Data type”选择8-byte Double,“Pass”选择Pointer to Value。 设置好之后的Call Library Function Node类似下图,...
Application Builder LabVIEW 中的一个组件，允许（专业版或单独购买的）用户创建可执行的 应用程序。参见 Build Specification。Array 由同类型数据构成，且元素按顺序排列的集合。Array Shell 前面版上的对象，可生成数组。它包括索引显示、数据对象窗口和一个可 选的标签，它可以接受各种数据类型。 Artificial Data Dep...
Workaround—Use the Convert to Dynamic Data Express VI to convert the scalar array to a dynamic data type before you wire the input to the function. — If your OS does not support time resolution at the fractional level, the fractional part of a timestamp is always zero, which means a...
until run time. LabVIEW,however, requires .NET objects to have a defined type in order to display theavailable methods in the .NET Invoke Node. Therefore, although LabVIEW allowsyou to call .NET methods that return a dynamic data type, you cannot use thereturned data to call other methods....
