Detail Engineering, EPC Execution.
Detail engineering is where transcription error costs the most. A miscounted analog input on the PLC card schedule means a returned panel. A wrong spec on the line list means a metallurgy mismatch caught at hydrotest.

P&ID extraction for detail engineering.
Detail-engineering documents from IFC P&IDs. ISA 5.1 I/O list, line list with metallurgy, loop tag clustering, exports to TIA Portal and Rockwell L5X.
What Detail Engineering produces.
- Issued-for-construction I/O list with full signal classification
- Instrument index with datasheet pointer per tag
- Line list with pipe spec, metallurgy, and service per line
- Marshalling and I/O-card count estimated from the I/O list
- Loop folders with one folder per loop tag
- PLC and DCS configuration tag tables exported to TIA Portal, Rockwell L5X, or PLCCreator
- SIS instrument index scoped for IEC 61511 functional safety review
Where Tagsight fits.
- Holds the instrument index, I/O list, and tag register reconciled to the P&ID master so every downstream document draws from the same controlled record
- Exports directly to the configuration tools detail engineering uses. TIA Portal XML, Rockwell L5X, PLCCreator CSV, JSON for custom toolchains
- Per-revision comparison surfaces tag changes between issued-for-review and issued-for-construction so MOC entries are pre-populated
- Equipment and line lists extract alongside the I/O list so the same workspace carries every controls document
- Loop tag clustering surfaces all tags that share a loop number so loop folder structuring is automatic
Common challenges.
- Line list and I/O list drift apart when maintained in separate spreadsheets. The same pipe carries different specs in different documents
- ISA 5.1 signal class assignment is mechanical but error-prone at scale. Misclassified tags ripple into wrong PLC card types and wrong loop folder templates
- MOC packages between revisions are hand-built from drawing markups. Structured comparison eliminates that hand work
- Loop folder construction by hand misses tags that share a loop number across pages
- Cable schedules built from the I/O list inherit any I/O list error and surface it during marshalling cabinet layout review
- Vendor datasheet matching to the instrument index is a separate workflow that depends on the index being clean before vendors are issued an inquiry list
Common questions
Can the extracted I/O list export directly into TIA Portal or Studio 5000.
Yes. Tagsight exports TIA Portal XML and Rockwell L5X tag tables. Both formats import into Siemens TIA Portal and Rockwell Studio 5000 respectively without manual reformatting.
How does the revision comparison work for MOC packages.
Each issued revision is its own extraction run within the workspace. The comparison report lists added, removed, and modified tags with the field-level changes called out. Output is a Change Report Excel file suitable for MOC documentation.
Does Tagsight produce loop folders or just the tag list.
The structured output groups tags by loop number, which is the spine of a loop folder. The actual folder PDFs, with datasheets, calibration sheets, loop diagrams attached are still assembled in a document control system, but the tag-to-loop mapping is automatic.
What if a tag appears on multiple drawings with different attributes.
When the same tag number appears on multiple pages, you see both occurrences in the canvas and decide whether they are one instrument or two, rather than having them silently merged.
Use it through Detail Engineering.
Every IFC revision requires the I/O list, line list, and equipment list to track with it. A structured extraction off the current drawing set, exporting to TIA Portal, Studio 5000, or PLCCreator with a revision comparison report, keeps the MOC package current without repeating the transcription step.
