Safety Audit — Allen-Bradley PLCs
Find Safety Logic
in Your Program
Upload your Allen-Bradley file and PLC Safety Analysis scans for safety-related logic: E-stops, light curtains, interlocks, faults, and alarms. Each finding links to the exact rung, with severity categories to help prioritize your audit.
- PLC Safety Analysis scans your Allen-Bradley program for safety-related logic like E-stops, guards, light curtains, interlocks, and alarms, then categorizes each finding by severity.
- Click any safety finding to jump straight to the rung it came from, so you can review the actual logic and verify the implementation.
- It surfaces and organizes existing safety logic for audit, review, and compliance documentation. It is not a functional-safety certification or SIL tool.
- Works on ACD, L5X, and RSS files without needing Studio 5000, RSLogix, or any Rockwell license.
What Safety Analysis
Can Find
Scan for Safety Logic
Finds E-stops, guards, light curtains, interlocks, faults, and alarms across your entire program automatically without manual review.
Severity Categories
Each finding is labeled by risk level so you know which safety features to prioritize in your audit or compliance review.
Clickable Citations
Click any finding to jump to the exact rung and routine, so you can verify the logic and document the implementation.
Works Without Licenses
No Studio 5000, RSLogix, or Rockwell software required, analyze your safety logic in a browser from any device.
Recover Documentation
Sees recovered comments, descriptions, and fault messages from the file so you understand the engineer original intent.
Organize for Compliance
Export findings by category and severity for your safety audit, OSHA review, or functional-safety documentation.
What is PLC Safety Analysis?
PLC Safety Analysis is a scanning tool built on top of your parsed Allen-Bradley program. When you upload a file, the tool reads every program, routine, rung, tag, and I/O module, plus any recovered comments and fault messages. It then identifies safety-related patterns and organizes them by type and severity level.
- Where are E-stop circuits implemented, and are they all properly wired?
- Which interlocks protect access doors, guards, or safety zones?
- What light curtains or photoeye logic exists in the program?
- How are alarms and faults latched and cleared?
- Which outputs or tags control safety-critical functions?
In our testing, the most useful part is finding safety logic that is buried in large programs and organizing it by severity level so you know what to focus on first in your compliance review. You can jump straight to each rung, verify the implementation, and export the findings to share with your team or include in your audit documentation.
How to Scan for Safety Logic
Upload your PLC file
Upload your Allen-Bradley ACD, L5X, or RSS file to plc.company. The safety analysis scans the entire program automatically.
Review the findings
Browse the safety findings organized by type (E-stop, interlock, light curtain, etc.) and severity level. Each finding links back to the source rung.
Jump to the rung
Click any finding to navigate straight to the ladder logic it came from, so you can verify the implementation and understand the safety flow.
Document your audit
Export or screenshot the categorized findings to include in your safety audit, compliance documentation, or team safety review.

Frequently Asked Questions
What is PLC Safety Analysis?
PLC Safety Analysis is a tool that reads your Allen-Bradley program and identifies safety-related logic like E-stops, guards, light curtains, interlocks, faults, and alarms. It categorizes each finding by severity and links it back to the exact rung, so you can quickly audit your safety logic without manually scrolling through hundreds of rungs.
Is this a functional-safety certification tool?
No. PLC Safety Analysis surfaces and organizes existing safety logic in your program for audit and review. It is not a functional-safety analysis tool, not a SIL calculator, and does not provide IEC 61508 certification. Use it to inventory and understand your safety features, not as a substitute for formal safety analysis.
Which Allen-Bradley files does PLC Safety Analysis support?
The tool works with ACD and L5X files from Studio 5000 (ControlLogix, CompactLogix, GuardLogix) and RSS files from RSLogix 500 (SLC 500, MicroLogix). It reads your entire program, tags, and any recovered comments to identify safety patterns.
Can I review safety logic without Studio 5000?
Yes. Upload your ACD, L5X, or RSS file to plc.company and PLC Safety Analysis reads and analyzes the code in your browser. No Rockwell software license, no network requirements, no installation needed.
How does the tool identify safety logic?
PLC Safety Analysis recognizes common safety patterns in ladder logic: E-stop circuits, interlock chains, guard inputs, light curtain logic, fault latch routines, and alarm sequences. It categorizes findings by type and severity so you can prioritize your audit and compliance review.
