HI, Every time when main VI calls subvi, those values/setting in subVI which are not connected with mainVI will go back to default values. How can I let subvi remember those values (which is changed in the last time call) as the setting in the next time call? WeiLV7.1

Well, in the first one, you do not that the "y" control linked to a terminal on the connector pane. The one that does not remember, you do. So when the subVI runs in the code that has the y value linked up, it uses the default value.

Yes, I know. But I can change the values on the subVI front panel. And this is exactly what I need.

Thank you very much.
