which you can encounter errors occurs when you perform any kind of input and output (I/O). Almost all I/O functions return error information. Include error checking in error cluster labview VIs, especially for I/O operations (file, serial, instrumentation, data acquisition, and communication), and provide a mechanism to handle errors effectively. Automatic Error Handling By default, LabVIEW automatically handles any error when a VI runs by suspending execution, highlighting the subVI or function where the error occurred, and displaying an error dialog box. Note The LabVIEW general error handler labview Run-Time Engine does not support automatic error handling. Disabling Automatic Error Handling You also can disable automatic error handling in preference of other error handling methods. For example, if an I/O VI on the block diagram times out, you may want the VI to retry for a certain period of time instead of allowing automatic error handling to stop the application and display an error dialog box. You can implement custom error handling on the block diagram of the VI. Refer to the following table for information about how to disable automatic error handling for different types of VIs. Type of VI Disabling Automatic Error Handling Current VI Select File»VI Properties. Then select Execution from the Category pull-down menu and remove the checkmark from the Enable automatic error handling checkbox. New, blank VIs Select Tools»Options. Then select Block Diagram from the Category list and remove the checkmark from the Enable automatic error handling in new VIs checkbox. SubVI or function with

N/A Secondary Software: N/A Problem: When I navigate labview error in no error to File»VI Properties»Execution, Enable Automatic Error Handling is selected by default when I create a new VI, is this expected behavior? How can I change this to be deselected when I create a https://zone.ni.com/reference/en-XX/help/371361M-01/lvconcepts/error_checking_and_error_handling/ new VI? Solution: This is the correct default behavior for a new VI after LabVIEW has just been installed. It can be disabled by opening a blank VI and navigating to Tools»Options...»Block Diagram, scrolling to Error Handling, and deselecting Enable automatic http://digital.ni.com/public.nsf/allkb/542F4881502A698B862576CC0079E74D error handling in new VIs. This will disable automatic error handling in the block diagram for all newly created VIs in LabVIEW.

I have a "Clear Errors" VI, which has an "error in" Input, an "error out" Output and a "no error out" error handling where - you guess right - no error comes out. I use this VI to clear the error wire, but "see" the error anyhow. If I don't connect the error out Output, I get one of these automaic error dialoges, which I don't want to have, because I'd like to "silently suppress errors" with this VI. I thought I could turn of automatic error handling for the VI with the VI properties. But even with disabled "Enable automatic error handling" I get the error dialog. labview error handling What can I do to get rid of the error dialoges? thank you in advance and cheers :beer: CB Download File:post-885-1161016140.zip Share this post Link to post Share on other sites crelf 274 I'm a LAVA, not a fighter.

If I'm understnading you correctly, you've disabled automatic error handling in the VI you attached - what you need to do is disable it in the VI that calls that VI - that's where the errors are handled since it realises an error is coming out of your subVI and isn't connect to anything - it's only once it gets out of the subVI and is properated up to the calling VI does it realise it's not being handled and pops up the dialog.
