## What is Loopstamp?

Loopstamp is a vendor-neutral I/O commissioning evidence desk for controls engineers, system integrators, building-automation teams, technicians, commissioning authorities, and industrial project teams.

Import or build a point list with tag, description, DI/DO/AI/AO type, panel, channel, units, acceptance band, expected state, approved stimulus description, observed result, witness, and note. Loopstamp computes expected-versus-observed status, flags duplicate assignments, keeps cause-and-effect checks beside point evidence, and assembles a live punch list.

KEY FEATURES
- Vendor-neutral DI, DO, AI, and AO point list
- CSV import with quoted-field support
- Panel and channel duplicate detection
- Analog acceptance-band evaluation
- Digital expected-versus-observed comparison
- Ready, complete, blocked, pass, and fail evidence
- Cause-and-effect witness records
- Automatically assembled punch list
- Local PDF and JSON commissioning export
- Complete hardware-free review project
- 340 original offline commissioning plates
