P&ID extraction for Triconex projects
Triconex projects work under a different discipline than the BPCS scope alongside them. Every instrument in the protective layer has to be identifiable on the drawings, in the SRS, and in the safety lifecycle paperwork without divergence between them. The full documentation scope for a Triconex project, including SIF logic capture and proof-test column layout, is covered in the build a SIS specification from existing drawings reference.
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.

- SIS-only I/O list filtered on protective tag prefixes and signal class
- Instrument index with voting annotations, 1oo2, 2oo3, 1oo2D preserved as drawn
- Cause and effect matrix scaffold derived from P&ID extraction plus uploaded cause-and-effect documents
- Equipment list scoped to safety-relevant final elements. PSVs, SDVs, BDVs, ESD valves
- Revision comparison reports between SIS drawing-set releases for MOC inside the safety lifecycle
- Off-page connector matching across multi-train drawing sets so cross-unit ESD interlocks resolve
- SIS extraction runs as a separate workbook from the BPCS scope so the safety case paperwork stays clean
- Voting annotations and redundancy markers are preserved verbatim, which is non-negotiable for the SRS and SIL verification documentation
- Cause and effect matrix output supports the standard SIS document required by IEC 61511 lifecycle phase 4
- Revision comparison surfaces added, removed, modified, and re-voted protective instruments between drawing-set generations. The exact granularity needed for MOC paperwork inside the safety lifecycle
Pressure switch high-high, voted 2-out-of-3, SIS service
Pressure alarm low-low, voted 1-out-of-2, SIS service
Shutdown valve, ESD service
Level switch high-high on overfill protection
Blowdown valve on emergency depressurization service
Do you produce Triconex configuration files.
No. The output is the SIS-scoped engineering dataset that feeds the configuration step. The logic build inside the safety controller, the SRS, and the SIL verification work remain with the functional safety engineer.
Are voting and redundancy annotations preserved.
Yes. Voting strings, 1oo2, 2oo3, 1oo2D and redundancy markers are extracted exactly as they appear on the drawings. They are part of the safety case and the extraction does not normalize them away.
Can BPCS instruments be excluded from the SIS workbook.
Yes. The SIS workbook filters on SIS-relevant tag prefixes, PSHH, PSLL, PALL, PAH, SDV, BDV, ESD-prefixed. BPCS instruments stay in the main workspace.
Are you partnered with Schneider Electric or Triconex.
No. Tagsight is independent. The page describes the engineering workflow on Triconex-based safety projects.
