Master Alarm Database auto-built from a DeltaV FHX export

The wedge

Native FHX import. Zero data prep.

Every competitor and every Excel workflow makes you manually extract, clean, and column-map an alarm list first. Bravura reads the DeltaV export you already have and auto-fills tag, module class, area, current priority, setpoint, engineering-unit scale, and deadband, on your own machine, with no DCS connection.

Built for real plant exports: a cancellable import with a live progress overlay stays responsive on multi-gigabyte FHX files of tens of thousands of alarms, with data-quality warnings surfaced instead of swallowed.

From FHX to first rationalized alarm in 5 minutes.

Design-time, complements your runtime monitor. Your runtime tool (DeltaV Analyze, PAS, ProcessVue) tells you which alarms are bad. This is where you decide what each alarm should be, and prove it.

Four reasons engineers pick Bravura

Built for the people who actually have to defend the alarm list, not the people who only have to monitor it.

Native FHX import

The only tool that reads the DeltaV export directly, recovering the EU scale, setpoints, and deadband that the standard DeltaV view drops.

Single-user, published price

Self-serve desktop, no quote-only sales gate, no consulting bundle to start. Buy the license, install, work.

Truly offline, air-gapped

Node-locked license file, no cloud, no phone-home. Fits locked-down OT networks and PSM-audited workstations.

Round-trip back to DeltaV

An import-faithful write-back FHX, proven on a live DeltaV 14.3.1 round-trip, with a full ISA-18.2 / IEC-62682 workflow and an audit-defensible trail.

What's in it

Six capabilities that turn a DeltaV export into a defensible alarm rationalization deliverable.

Auto-built MADB grid

Every alarm with dedicated Setpoint, EU scale, and Deadband columns, current vs recommended priority. Column sorting (priority by severity rank), find-as-you-type, and multi-select bulk edit with a safe copy-to-class: dry-run preview, fill-blanks vs overwrite, and skipping Approved targets so you cannot accidentally clobber signed-off work. Import a runtime alarm-frequency CSV to sort and tackle the worst bad actors first, and a flag highlights alarms whose annunciation is partially suppressed (non-default mask).

Guided rationalization

The mandatory ISA-18.2 9.2.1 fields and recommended 9.2.2 fields grouped Required / Recommended / Additional, a consequence x time-to-respond priority matrix that persists and reloads, alarm classification, and per-plant-state variants (Normal, Startup, Shutdown, Maintenance). Mandatory fields are highlighted until complete; rejecting an alarm requires a written basis. Prev/next plus next same priority and next unrationalized let you work through the whole list without leaving the form.

Functional safety (HAZOP / LOPA)

A Layer-of-Protection-Analysis worksheet per IEC 61511 / CCPS. Compute the mitigated event frequency, risk gap, and recommended SIL. Credit an alarm's operator response as an Independent Protection Layer only when it meets the ISA-18.2 criteria: independent of the cause, Highly Managed Alarm, and adequate time to respond.

Audit-defensible by design

Approve is blocked until the six mandatory 9.2.1 fields are complete; the button shows exactly what is missing. Approvals capture the approver name and timestamp (a per-machine reviewer name, not a generic "engineer"). One-click whole-project audit-trail export carries a document-control header (project, revision, source FHX path and SHA-256) so MoC and PSM reviewers can confirm exactly which build the artefact came from.

Alarm philosophy and audit settings

Benchmark dashboard

Priority distribution mapped to the ISA-18.2 Table-6 target (as-configured vs rationalized) with a within-budget verdict, plus chatter / deadband and completeness proxies.

Versioning and multi-project

Multi-project manager, baselines, and revision diffs covering priority, setpoint, deadband, delay, EU scale, MASK, and INV (not just priority). Re-import an updated FHX any time and carry rationalization forward without losing approvals; the re-review queue flags any rationalization whose as-built values drifted, and import surfaces data-quality warnings instead of silently swallowing them.

DeltaV-aware write-back

The write-back sends only what DeltaV will actually accept, as a minimal, merge-safe override (only the changed priority, or a disable), not a full alarm replace. It flags on each alarm, in the grid and the rationalization form, exactly what cannot be re-imported and why, before you export: an alarm whose module class does not expose it for instance editing, a device alarm, or a rationalized priority that is not configured on the source system. No surprise import rejections.

Exports that close the loop

MADB to CSV and a real Excel workbook (Document-Control sheet, typed numerics, AutoFilter, column widths, priority colouring; not a glorified CSV). A branded Alarm Response Manual plus priority-distribution and gap/drift reports, with document-control headers and optional per-project branding (company name and accent colour). In-app PDF export of the Alarm Response Manual and the reports, ready to attach to MoC paperwork. An import-faithful DeltaV write-back FHX that re-imports your priority changes and disables the alarms you rejected (validated on a live DeltaV 14.3.1 round-trip). And a whole-project audit trail with a per-revision change log.

First-run onboarding and a built-in user guide

A short first-run walkthrough takes a new user from FHX to their first rationalized alarm without reading documentation. A built-in user guide is one click away inside the app.

Built to the standards your auditors cite

Bravura speaks the language of ANSI/ISA-18.2, IEC 62682, and EEMUA-191: alarm philosophy, master alarm database, priority matrix, rationalization fields, performance metrics, and management of change.

Runs fully offline on air-gapped OT networks. Your alarm data never leaves your machine.

Frequently asked questions

Does it really run fully offline?

Yes. Bravura is a single-user Windows desktop app. Install once on your workstation, copy the license file, work. There is no cloud account, no telemetry, and no phone-home check.

What happens to my alarm data?

It stays on your machine. Bravura reads the FHX you point it at, stores the project locally, and never uploads alarm data anywhere.

Which DeltaV versions / FHX exports are supported?

Modern DeltaV exports (v13 and later). The importer reads engineering-unit scale, setpoints, deadband, and module-class structure, so the recovered MADB matches what is actually configured on the system.

How is this different from a runtime alarm monitor?

A runtime monitor (DeltaV Analyze, PAS, ProcessVue) tells you which alarms are misbehaving right now. Bravura is design-time: it is where you decide what each alarm should be, document it to ISA-18.2, get it approved, and write it back to DeltaV. The two are complementary.

How large an FHX export can it handle?

Real plants. Bravura has been validated on multi-gigabyte FHX exports of tens of thousands of alarms (1.25 GB, ~32,000 alarms tested), with a cancellable import and a live progress overlay so the UI stays responsive while it loads. If something is wrong with the source file, you get a data-quality warning instead of a silent skip.

Can I refund?

Yes. If Bravura does not work for your DeltaV export, contact support@bravura-ai.com within 30 days for a refund.

Do I need internet to install or use it?

No. The installer is a standalone Windows setup, and the license file activates on the workstation. The only time you need internet is to receive your license file by email (which you can transfer offline to the air-gapped machine).
