--- title: "AUVY for system integrators: IO lists and specs on record" description: "AUVY compares IO list and spec revisions, finds the panels and checklists they touch and gets extra signals into a change request before the work is done." url: https://www.auvy.ai/use-cases/system-integrators lang: en site: AUVY brief: https://www.auvy.ai/llms.txt --- # Revision D replaces revision C. AUVY shows what that means before commissioning. Extra signals get built because start-up can't wait, and they rarely reach an invoice. AUVY compares every IO list and specification revision the customer sends, names the panels and checklists it touches and drafts a change request while there is still time to bill it, for the project lead to sign off. [← Use cases](https://www.auvy.ai/use-cases) For: Owners, project leads, PLC and panel engineers, commissioning teams System integrators & automation ## A week in integration. The customer uploads IO list rev D with 14 new signals, three renamed and two on a panel already built. The commissioning checklist still reads rev C, and the site team finds out at the machine. Use cases ## What comes in, and what AUVY does with it. 1. When ### The customer uploads IO list rev D. AUVY Names the added and renamed signals since rev C and finds the panels and checklists that still rely on rev C. You get Tasks for PLC and panel build with owners and dates, and a change request for the extra signals. Reads IO list rev C ↔ D · Checklist v5 2. When ### The specification changes after the order. AUVY Marks the changed requirements against the version you quoted on and names the parts of the design they touch. You get A change request with its sources, for the customer to approve by link. Reads Specification versions · Offer 3. When ### The FAT produces a punch list. AUVY Links each item to the requirement it refers to and separates defects from new wishes. You get Defects as tasks and new wishes as change requests. Reads FAT notes · Specification 4. When ### On site, the commissioning engineer asks which parameter set is valid. AUVY Answers from the project's documents with the version and page it read. You get An answer with its source, on a phone at the machine. Reads Parameter lists · Mails Sources ## Every answer shows its work. Before a partner puts an answer in front of a client, they want to know where it came from. In AUVY that takes one click.

Example project, synthetic data. Meetings ## Kick-off, FAT, site commissioning meetings. Meetings Before After Kick-off and design review The specification as quoted, open questions and assumptions the customer has not confirmed. Answers logged against the requirement they settle, and changes marked against the quoted version. Factory acceptance test What changed since the design review and which tests it affects.

Give the project each revision, and AUVY names what was added, removed and renamed, with the file and row as the source. ### Does AUVY connect to PLCs or SCADA? No. It reads the documents, lists and mails you give the project, and your engineering tools stay as they are. ### Can subcontractors join a project? Yes. A panel builder or other partner is invited into one project and sees only that project. Also read - [Machine building & engineer-to-order The customer changes the order after release.
