Built for unfamiliar programs

Get from a tag to the logic that matters.

Studio Savior turns a full-project L5X export into a navigable view of references, AOI mappings and logic relationships so you spend less time manually chasing context.

AOI-aware cross-reference

Follow external operands through AOI parameter bindings and into the internal logic that actually uses them.

Upstream & downstream tracing

Explore potential writers, readers and dependencies while preserving AOI context and the reference chain.

Interactive reference chain

Keep your path visible as you move through tags, rungs and AOIs instead of losing your place during cross-reference dives.

Unused-tag analysis

Find tags with no detected internal references, flag external-access uncertainty and surface potential memory bloat without claiming unsafe deletions.

Visual rung context

See references in whole-rung context with highlighted operands and navigable action targets.

Large-project analysis

Analyze full Studio 5000 L5X exports locally with cached parsing and multicore scanning designed for production-scale projects.

Local-first by design

Your PLC logic stays on your machine.

Normal Studio Savior analysis runs on your Windows computer. Your L5X project is not uploaded to Elwell Automation Consulting LLC for analysis.

The online service is used for account, subscription, license entitlement and release/update information—not to process your PLC project.
