Tagsight vs OpenPlant-style workflows
OpenPlant-style workflows hold P&ID content in a shared engineering data store, with intelligent diagrams above and downstream design tools below. Tagsight is drawing-first. Input is a rendered PDF, output is structured I/O data.
At a glance · Time per drawing
Minutes per drawing for extraction. Engineer time goes to review, not transcription.
Depends on how complete the data store is for that drawing. Drawings outside the store need separate handling.
Read one of your own drawings.
Drop a P&ID, instrument index, or schedule. Tagsight reads it to the tag and opens a workspace you keep when you sign in.

Comparison.
| Axis | Tagsight | Alternative |
|---|---|---|
| Time per drawing | Minutes per drawing for extraction. Engineer time goes to review, not transcription. | Depends on how complete the data store is for that drawing. Drawings outside the store need separate handling. |
| Revision handling | Two PDF revisions diffed automatically. Change Report exports as MOC-ready Excel. | Managed inside the data store for stored drawings. External drawings handled separately. |
| Signal classification consistency | Classification is consistent across every drawing in the project. You confirm the ambiguous reads in the canvas before export. | Depends on how the store was configured and the discipline of tagging during diagram authoring. |
| Audit trail | Per-tag source page, source region, and review decision. Queryable and version-controlled. | Audit trail inside the data store. Out-of-store drawings have no equivalent record. |
| Output formats | Excel, CSV, TIA Portal XML, Rockwell L5X, PLCCreator, DEXPI, JSON, annotated PDF as native exports. | Output formats depend on the modeling environment build and licensed modules. |

When this is the right call.
- Controls documents, I/O, equipment, line lists are the primary work and a full data store is unnecessary overhead
- Project includes scans or PDFs that were never stored in the engineering data store
- Audit trail is needed for MOC, HAZOP, or SIS without a centralized data store
- The team prefers a pay-per-use cadence over per-seat modeling licenses for extraction work
When it is not the right call.
- Project requires bidirectional integration with downstream 3D plant design tools that read directly from the data store
FAQ.
Does Tagsight need access to the OpenPlant-style data store.
No. The input is the rendered drawing. The system does not connect to or read from any external engineering data store.
Can the two run side by side.
Yes. Many teams keep the modeling environment for diagram authoring and use Tagsight for extraction-driven documents.
What about drawings imported from another EPC.
These usually arrive as PDFs without store metadata. They run the same way as native drawings.
Is DEXPI supported.
Yes. DEXPI 1.3 XML is one of the standard exports.
What scale of project does this fit.
From a single skid to multi-hundred-page brownfield programs. Pricing is pay-per-use, so scope can flex without procurement cycles.
