Illustrative use case

PLC / HMI / SCADA design & verification

Specifying and verifying the control system of a new filling machine before GMP use.

AutomationQuality Illustrative use case
Operators interacting with HMI panels on a cleanroom filling machine

Challenge

The vendor’s standard documentation did not cover user access, audit trail or data retention needs.

Requirement

A control system that meets process and data-integrity requirements, with documented verification.

Approach

Write a URS with data-integrity requirements, review the functional design, and plan risk-based FAT/SAT and qualification.
