动态调用中为什么子vi无法打开

[sanchuaner]

我用open vi referrence动态调用子程序，在type specifier  vi refrum变成严格类型后，接入call by reference node 再接入close reference及simple error handler。运行没有出错，但是子vi就是不弹出来。 还有一个现象，call by reference node的连接器模块就变成一个空白的框，也没有输入输出，就是说并没有生成适当的连接器模式。

有人遇到过这种情况吗？ 请求帮助。

If you want the dynamic VI (sub-VI) to show up during execution, set TRUE to property FP.Open before calling by reference node.

As for why you do not see the I/O connector (in the Call By Refrence Node), it is most likely that you did not assign the I/O to the connector pane.

Attached example fyr 😉
