In LabVIEW, when a VI has Automatic Error Handling enabled, it will handle errors that occur within its execution unless the error is propagated from a SubVI that has Automatic Error Handling disabled. In this scenario, the presence of Automatic Error Handling in the main VI means it is set up to manage errors automatically; however, for any errors occurring in the SubVI, this setting does not take control.

When the SubVI has Automatic Error Handling disabled, it will not manage errors on its own. If an error occurs within that SubVI, it will simply pass the error out through the Error Out terminal. If the calling VI does not wire the Error Out terminal of the SubVI to any other node or error handling mechanism, the error generated by the SubVI will not be communicated to the main VI effectively.

Therefore, if the Error Out terminal from the SubVI is not wired in the calling VI, the calling VI will remain unaware of any error that occurred in the SubVI. This lack of wiring prevents the main VI from receiving the error information, leading to the conclusion that while the SubVI did experience an error, no visible impact or error handling occurs in the calling VI due to this disconnection.
