Using the General Error Handler to Create User-Defined Error Codes using LabVIEW

[John_P1]

Overview
This example VI demonstrates how to create custom error messages in LabVIEW.

Description
In LabVIEW you are able to create custom error codes using native APIs such as the General Error Handler.vi. In this example five custom error codes and relative messages are used to warn the user about possible failures that can happen in different sections of the program.

Requirements

• LabVIEW 2012 (or compatible)

Steps to Implement or Execute Code

1. Download the attached files to your computer
2. Open the VI "User-Defined Error Codes LV2012 NI Verified.vi"
3. Run the VI
4. Select the error code from the enum control and press Display Error Code

Good example, thanks, I'll probably implement something using this information.  The loop though, has no delays, thus it will very quickly do nothing if "Display Error Code" is set to false.
