Although AutoCAD Electrical checks for duplicated schematic component reference designations and wire numbers during the insert or edit process, you have the option of displaying the warning in real time. Real-time error checking is enabled by default in the Project Properties
Project Settings tab.
If you enter an existing component tag/wire number during the insert/edit process, a warning dialog box displays. This alerts you of the duplication and suggests alternative tag names based on the user-defined format. You can select whether to use the duplicated tag or use a new tag that is suggested (or you can type in a new tag).
Note: The combined value of the component tag and installation code is used for error checking in IEC mode.
An error log file is created for every project if you chose to display the real-time warnings. The real-time warning is saved in the log file named "<project_name>_error.log" and is saved in the User subdirectory. If a log file exists, the new content is added to the same file. A blank line separates one error record from another.
About the .wdn file
The .wdn file is a text file used specifically for auditing terminals. Terminal numbers listed in this file are not checked for duplication. Use wildcards to exclude a range of terminals for duplication checking such as all terminals with a tag name starting with "T" and with terminal number "1." AutoCAD Electrical searches for the <project_name>.wdn file in the same folder as the project definition file (*.wdp). If <project_name>.wdn is not found, AutoCAD Electrical looks for the default.wdn file in the project folder.
The default .wdn file contains the terminal number filters GND, PE, and E. They are ignored when checking for duplication and are not listed in the Electrical Audit report.
Use the troubleshooting tools
There are many tools to use for troubleshooting your AutoCAD Electrical drawing.
Use the audit tool
Use this tool to identify and clean up some types of problems that affect an AutoCAD Electrical drawing. The Electrical Audit tool displays a report of detected problems for the active project. You can save this file for reference or surf the file to view and correct the errors.
Schematic panel
Electrical Audit.When you run the command, the progress bar describes the progress of the audit process. Once the audit is complete, a text box displays the total number of errors found.
They are the areas where problems were found in your project. If no errors are found, the Details button is not enabled.
Once you browse to an error location an 'x' appears in the audit dialog box.
After correcting the error, you can select another audit record in the dialog box for correction.
Note: Run the Drawing audit tool to perform wire-related clean-up functions automatically.
Clean the drawings
Troubleshooting panel
Clean DWG Utility.New, clean copies of the selected drawings are created and inserted into the drawing.
Use the debug tool
If you receive a message that AutoCAD Electrical is having trouble updating your scratch database file of the project, turn on the Debug Trace. It can help track down the problem. Select one of the following commands:

Check, repair, or trace wire and gap pointers
The Check/Repair Gap Pointers utility verifies that the invisible Xdata pointers on both sides of a wire gap/loop are valid. If not, appropriate pointers are established. The Check/Trace a Wire utility single steps through and highlights each connected wire of the selected wire network.
Check/repair wire gaps
Use this utility to create wire number jumps (on the current drawing) without resorting to individual signal source/destination arrow symbols.

Electrical Audit
Command entry: AEAUDIT
When you run Electrical Audit, a progress bar shows the progress of the audit process. Once the audit is complete, a text box displays the total number of errors found. The Details option lists the detected problems. You can go to the location of an error within the project and correct the error.

Project | Displays the audit information for all the drawings in the active project. |
Active Drawing | Displays the audit information for the active drawing only. If a different drawing becomes active, the display updates for that drawing. If the active drawing is not part of the project, the Active Drawing control is disabled and the Project control is selected. |
Wire - No Connection | Displays the unconnected wires for the active project. The report lists the unconnected wire number, location point, error message, and the drawing where the error occurs. If there is not a record of a wire number, the wire number column is blank. |
Wire Exception | Displays missing or duplicated wire numbers for the active project. The report lists the duplicated wire number, error message, and the drawing where the error occurs. If a wire number is missing, the wire number column is blank. |
Cable Exception | Displays the duplicated cable and wire id for the active project. The report lists the duplicated cable tags or cable tags with duplicated wire id, error message, reference of the cable tag, and the drawing where the error occurs. |
Component - No Catalog Number | Displays components with no bill of material part assignments. The report lists the component reference designation tag, component category, reference of the component tag, error message, and the drawing where the error occurs. |
Component Duplication | Displays the duplicated components. The report lists the component reference designation tag, component category, reference of the component tag error message, and the drawing where the error occurs. |
Component - No Connection | Displays component connections with no connected wires. The report lists the component reference designation tag, component category, reference of the component tag, error message, and the drawing where the error occurs. |
Mixed Component Network | Displays components in the wire network that carry a mixture of different WDTYPE attribute values. For example, a one-line symbol (WDTYPE value of "1-") connected to a schematic symbol (WDTYPE value missing or blank). |
Terminal Duplication | Displays duplicated schematic terminal numbers. The report lists the terminal tag id and duplicated terminal number, reference of the terminal number, error message, and the drawing where the error occurs. Note: Terminal numbers listed in WDN files (located in the same folder as the project definition file (*.wdp)) are not checked for duplications. You can use wildcards to exclude a range of terminals for duplication checking using this text file. |
Pin Exception | Displays duplicated component pin assignments. The report lists the schematic component reference designation tag and component wire connection pin, reference of the component tag, error message, and the drawing where the error occurs. |
Contacts | Displays any children without a parent schematic component. The report lists the component reference designation tag for the child without a parent, reference of the child component tag, error message, and the drawing where the error occurs. |
Recovery Tip | Displays the recovery tip so that you can fix the error. |
Go To | Goes to the error location within the project and correct the error. It is enabled when you select a single audit record in the dialog box. Once you browse to an error location an "x" appears in the left-hand column of the Electrical Audit dialog box. Note: You can also double-click an audit record to go to the error location. |
