Impact for the plant director
F.A.T. STATION

A single digital flow for testing, alarms, reports and machine archive.

The demo closes the loop: the operator works in a single session, the supervisor sees the whole shop floor, QA signs a certificate consistent with the acquired data, and the history stays available for audits, post-sale and disputes.

Fewer disconnected tools
1
trend, P&ID, HMI, alarms and certificate live in the same platform instead of scattering across HMI, Excel and shared folders.
More line control
live
each machine occupies a dedicated line with current phase, status, recording criteria and alarms already readable from the dashboard.
Complete audit trail
100%
ACK, signatures, safety blocks, samples and phase transitions stay correlated to the acceptance session and the final certificate.
Low-risk rollout
step
start from a pilot line, then extend to the shop floor and further sites without changing the operating model.
STEP 01
Pilot line
One machine, one line, templates and reports already standardized.
STEP 02
Full shop floor
Multi-line dashboard, operator/QA roles and a single plant archive.
STEP 03
Industrial group
Multiple shop floors on the same platform with shared governance and history.
STEP 04
After-sales
Trends, reports and audit trail available even after the machine acceptance test.
