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.
Install Pulse, connect to a supported Allen-Bradley Logix PLC, and evaluate the software on real machine data. No credit card is required to start the trial.
The same installer is used for both the free trial and the full licensed product.

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.
Pulse inspects accessible controller definitions and identifies likely faults and diagnostic signals using tag names, structures, and confidence scoring.
High-confidence BOOL diagnostics can be monitored automatically alongside the tags you explicitly choose, without creating another PLC programming dependency.
Diagnostic transitions are timestamped and correlated into incidents with first-observed events, recovery tracking, and incident duration.
Open and monitor multiple saved PLC profiles independently from one plant dashboard.
Browse controller tags, save monitored tags and favorites, and return quickly to the machines you troubleshoot regularly.
Trend selected numeric tags and export captured data for troubleshooting, process review, and documentation.
Colotti Pulse is intended for monitoring and diagnostics. It does not provide PLC write, force, edit, download, or controller mode-change functions.
Pulse is built around practical monitoring of supported Allen-Bradley Logix controllers and the tags used in real manufacturing equipment.
Keep using the same installed application after the trial. Purchase a perpetual single-seat license and activate it from inside Pulse.
Secure checkout and payment processing are provided by Stripe.
Your trial installation does not need to be removed. After purchase, use Activate Purchased License inside Pulse and enter the license key issued after checkout.
The machine-specific signed license is stored locally after activation, so Pulse does not require continuous internet access to validate a paid license.
You can evaluate the full application before purchasing. If Pulse fits your workflow, upgrade the same installation to a perpetual license.
