Colotti Pulse 1.2.1 · Read-only industrial PLC diagnostics

See What Your Allen-Bradley PLCs Are Doing — Without Opening a Programming Project

Colotti Pulse is a lightweight Windows monitoring and diagnostics application built for controls engineers, maintenance teams, and integrators who need fast PLC visibility without adding another programming station.

Pulse can automatically discover likely diagnostic signals, monitor high-confidence fault BOOLs, build a live diagnostic timeline, correlate transitions into incidents, and track recovery and duration — all while keeping PLC access read-only.

Built for Real Troubleshooting Work

Pulse combines live PLC visibility with automatic diagnostic discovery so you can spend less time deciding what to watch and more time understanding what happened.

Automatic Diagnostic Discovery

Pulse inspects accessible controller definitions and identifies likely faults and diagnostic signals using tag names, structures, and confidence scoring.

Automatic Diagnostic Monitoring

High-confidence BOOL diagnostics can be monitored automatically alongside the tags you explicitly choose, without creating another PLC programming dependency.

Diagnostic Incident Timeline

Diagnostic transitions are timestamped and correlated into incidents with first-observed events, recovery tracking, and incident duration.

Multi-Machine Dashboard

Open and monitor multiple saved PLC profiles independently from one plant dashboard.

Live PLC Tags & Profiles

Browse controller tags, save monitored tags and favorites, and return quickly to the machines you troubleshoot regularly.

Trend & Export

Trend selected numeric tags and export captured data for troubleshooting, process review, and documentation.

Read-Only by Design

Colotti Pulse is intended for monitoring and diagnostics. It does not provide PLC write, force, edit, download, or controller mode-change functions.

Designed for Allen-Bradley Environments

Pulse is built around practical monitoring of supported Allen-Bradley Logix controllers and the tags used in real manufacturing equipment.
