Tagsight vs spreadsheet-only I/O workflow.
Tab-per-document Excel workbooks are fine on a single skid project. The trouble starts at the second revision. Tabs drift apart, cross-document consistency cracks, and the file becomes a weekly reconciliation exercise nobody owns.
Comparison.
| Axis | Tagsight | Alternative |
|---|---|---|
| Cross-document consistency | Single source-of-truth tag set. Instrument index, I/O list, line list, equipment list all derive from the same extracted data. | Tabs drift apart over revisions. The same tag appears with different descriptions or signal classes in different documents. |
| Revision management | Two extracted revisions compared in one click. Deltas exported as MOC-ready Excel. | Manual cell-by-cell comparison. Common to miss tag adds or moves. |
| Export targets | Native exports to TIA Portal XML, Rockwell L5X, PLCCreator, DEXPI, and JSON. | Hand-built exports per target system. High error rate at the spreadsheet-to-PLC boundary. |
When this is the right call.
- Project has more than one document that depends on the tag set
- Tag set will be re-used across drawing revisions
- Project needs to export to a control system without manual re-typing
When it is not the right call.
- One-off I/O list for a small skid where Excel will be the final document
Common questions
Can I keep my existing Excel I/O list and just import it.
Yes. Tagsight ingests an existing Excel I/O list, normalizes signal classes, and lets you cross-reference it against newly extracted P&ID drawings. Match, new, missing, and disagreement buckets surface automatically.
