GxP & Compliance
Standard PI Vision lacks version control, making it difficult to use in regulated (GxP) environments. We introduce the first plugin that enforces a true validation lifecycle for your critical displays.
The "Wild West" vs. The "Validation Cycle"
In a standard PI Vision environment, a "Save" overwrites the previous version instantly. In a regulated environment, that is a data integrity risk.
Native PI Vision
The Risk: Anyone with write access can open a "Validated" display, move a trend, delete a KPI, and hit Save.
The Consequence: There is no approval process. There is no easy way to see *what* changed. The previous approved version is lost forever.
Vision Audit+
The Solution: A forced lifecycle. Displays move from Draft → Review → Validated.
The Control: Once a display is "Validated," it is locked. To make changes, a user must "Check Out" the display, creating a new Draft version, while the Validated version remains live for operators.
Enforcing 21 CFR Part 11 Compliance
Vision Audit+ brings the rigour of a Quality Management System (QMS) directly into your PI Vision server.
1. The Approval Loop
Workflow Enforcement
- Check-In / Check-Out: Prevent concurrent editing conflicts.
- Electronic Signatures: Require a username and password re-authentication to move a display from "Draft" to "Approved."
- Attestation: Force users to select a "Reason for Change" from a pre-defined list.
2. "What Changed?"
Visual Change Detection
- Side-by-Side Compare: View the current version against the previous version.
- Highlight Changes: We detect if a data source was swapped, a limit changed, or a symbol deleted.
- XML Forensics: For IT teams, view the raw XML diff to catch subtle configuration shifts.
3. The Safety Net
Instant Rollback
- Recycle Bin: Restore displays that were accidentally (or maliciously) deleted.
- Version Rollback: Did a new deployment break the dashboard? Click "Rollback" to instantly revert to the last known good configuration.
Why Quality Assurance Loves This
Move your PI Vision system from "Information Only" to "GxP Critical".
Audit Readiness
When an auditor asks for the change history of a display, generate a PDF audit trail report in seconds, showing every edit, author, and timestamp.
Tamper Protection
Server-side enforcement ensures that locked "Validated" displays cannot be modified via URL hacks or API backdoors.
Incident Investigation
If a dashboard showed incorrect data during a batch run, use the "Time Machine" feature to see exactly how the display was configured at that moment.
