For Rockwell / Allen-Bradley controls engineers

Complete project documentation from any Studio 5000 export. In 30 seconds. 100% offline.

Point PLCDocGen at an .L5X file and get a formatted Word report: full tag database, cross-references, AOI definitions, alarm summary, and rung-comment narrative. No cloud. No subscription. Your code never leaves your machine.

Get PLCDocGen — $79 One-time purchase · Windows .exe · Free updates for v1.x
PLCDocGen Windows app: a batch of five .L5X exports loaded, three report styles to choose from, and five Word reports generated with zero failures

The whole workflow: add (or drag in) your .L5X exports, pick a style, click Generate.

You know this job. You just hate doing it.

Every commissioning handover, every audit, every "can you send us the as-built docs?" email means hours of copy-pasting tag lists into Word and manually tracing where things are used. It's the least valuable use of a controls engineer's time — and it's always due yesterday.

Full tag database

Controller and program scope, data types, descriptions — formatted tables, not screenshots.

Tag cross-reference

Every tag mapped to program / routine / rung. Unreferenced tags flagged automatically.

AOI documentation

Parameters, dependency chains, and revisions for every Add-On Instruction in the project.

Alarm & fault summary

ALM / FAULT / TRIP / ESD pattern tags collected into one table for rationalization reviews.

Logic narrative

Your rung comments compiled into a readable sequence description — the doc reviewers actually read.

Quality checks

Description coverage %, undocumented tags, dead tags — know what to fix before the client asks.

Sample report page: controller summary, program structure and tag tables

One export, three reports

Pick the style that fits the reader: Full Reference for the as-built package, Commissioning Handover for the startup tech on the floor, or Audit Summary for the manager who wants metrics and findings on four pages.

Use the Windows app — add files, pick a style, click Generate — or drive it from the command line for batch jobs. See full sample pages →

Why offline matters: cloud AI copilots want you to upload plant code. Your IT department, your NDA, and your OT security policy all say no. PLCDocGen is a single .exe that runs on an air-gapped machine. Nothing is transmitted, ever.

Three steps

  1. In Studio 5000: File → Save As → .L5X
  2. Drag the file onto PLCDocGen.exe (or run it from the command line)
  3. Open the generated .docx — send it, brand it, or attach it to the handover package

Works with exports from RSLogix / Studio 5000 v20 through v38+.

Built by an automation engineer with 20+ years in safety-critical industrial systems and OT cybersecurity (IEC 62443) — which is why it's offline-only by design, not as a feature.

Built by a controls engineer, not a SaaS company

I'm an industrial automation systems engineer. I built PLCDocGen because documentation handover was the most tedious part of every project I commissioned. It does one job, does it offline, and costs less than one billable hour.
