请教invoke node 调用子函数遇到的问题

[navy5258]

本人在使用invoke node 调用子函数时总是提示有问题，请高手帮我解答一下，下面附上错误提示和程序框图：

From the graph attached, i think you are using a method of calling SubPanel rather than SubVI. For subpanel, you may find examples in LabVIEW that you will need a frame of Subpanel. For dynamic calling subvi, you may refer to "dynamic load example.vi" in LabVIEW.

按下call & run按钮之后，你的subVI已经运行了，然后执行下次循环的时候还会在调用VI SERVER，就会产生这样的错误了，因为此时该VI正在处于运行状态。

写了小逻辑判断一下VI是否在运行，如果运行的话，就不用再执行调用VI的panel了。
