PLC project utility
L5K / L5X Tag and Alias Workbench
Turn a text-based Logix project export into a searchable tag inventory without sending the file to a server. Start from the built-in motor example or unlock local file and paste intake.
L5K / L5X tag and alias workbench
Extract controller, program, routine, base-tag, alias, description, initial-value, and likely field-role metadata. The parser never executes ladder, structured text, Add-On Instructions, or controller code.
Tag inventory
Role suggestions are name-and-description heuristics for review—not proof of PLC behavior.
| Tag | Scope | Type | Suggested role | Alias / initial value | Description |
|---|---|---|---|---|---|
| Start_PB | Controller | BOOL | Start / run request | 0 | Operator start pushbutton |
| Stop_Circuit_OK | Controller | BOOL | Stop request / healthy chain | 1 | Hardwired stop circuit status |
| Safety_System_OK | Controller | BOOL | Safety / guard status | 1 | Status from the separate safety system |
| Motor_OL_OK | Controller | BOOL | Motor fault / overload | 1 | Starter overload healthy |
| Motor_Run_Cmd | Controller | BOOL | Output command | 0 | Standard PLC motor command |
| Motor_Run_FB | Controller | ALIAS | Run feedback / proof | Local:2:I.Data.0 | Starter auxiliary feedback |
Documentation review and revision comparison
1 tags have no description. 0 duplicate scoped tag identities need review.
Alias targets in this export
- Controller/Motor_Run_FB: Target not in export: Local:2:I.Data.0
Save the filtered tag rows as an I/O job, then open the Pro I/O checkout and restore the saved version. Alias targets are documentation references, not verified expected states; review each imported row.
Format reference: Rockwell Logix import and export.
Project boundary
A Logix export can contain proprietary equipment names, addresses, comments, and control structure. Review company policy before opening one. This client-side parser intentionally does not evaluate rungs, routines, AOIs, safety signatures, forces, online values, cross references, or whether a tag is actually used.
L5K PLC tag and routine explorer
Inspect a safe built-in motor-control L5K example and preview its extracted tag inventory.
Open or paste a browser-local L5K export, search and filter the complete tag inventory, and copy or download CSV metadata.
- Local .L5K file and paste intake
- Controller, program, routine, tag, and alias inventory
- Filtered CSV copy and download
Toolkit unlocks advanced tool operation. Pro Toolkit adds the troubleshooting knowledge base, field-document builders, and included library downloads.

Supported input
Use a text `.L5K` or XML `.L5X` export. Binary `.ACD` project files are intentionally unsupported. Export handling stays in the browser and is limited to 10 MB.
