PLEXUS EXAMPLE · 01
P&ID tag extraction
One P&ID sheet in, checkable registers out: equipment, instruments, valves and lines, with every value a reviewable candidate.
Input
DOCUMENT REFERENCEACD-300-001
Effluent Cooling & Gas/Liquid Separation
- Revision
- Rev 0 (IFD)
- Sheet
- 1 of 1
The source P&ID is not shown: client drawings stay inside your project. The registers below come from a hypothetical plant (ACD), presented the way extraction results arrive.
What Plexus does
- 01Extracts every tag on the sheet: equipment, instruments, valves and lines.
- 02Builds one checkable register per class.
- 03Flags uncertain items for an engineer.
- 04Treats every entry as a suggestion until an engineer confirms it. The engineer can also edit, add or remove any entry.

This animation illustrates the Plexus workflow on a hypothetical plant (ACD). In the product, extraction runs server-side and every value keeps provenance to the source document; an engineer reviews and confirms.
