P&ID to instrument index.
Your P&ID set becomes the facility-wide instrument index. Every instrument tag deduplicated across every sheet in the project, paired with its loop, signal class, linked equipment, datasheet reference, and source drawing.
Three drawings included on a new account.
One source for the instrument index, I/O list, and equipment list.
The instrument index ships as a spreadsheet alongside the I/O list and equipment list, so all three documents stay in sync from a single source.
From sheets to a master list.

Every tag, in the convention it was drawn in.
A multi-site project with mixed conventions merges into one instrument index, every tag in the form its own sheet prints it.

Common questions
How is the instrument index different from the I/O list?
The I/O list is the controls document: one row per signal, with the columns the PLC and DCS team need to assign and wire. The instrument index is the facility-wide master list: one row per instrument tag, with the columns process and maintenance engineers reference across the asset lifetime. They share the same source extraction, presented for different audiences.
What happens when the same tag appears on multiple drawings?
The two rows are deduplicated into a single index entry. The P&ID sheet column lists every drawing the tag was found on, and any conflicting service descriptions or loop assignments are presented for your review.
Can I upload an existing instrument register?
Yes. Upload it as an Excel reference file. Tagsight cross-references the extracted index against the register and flags tags that appear on the drawings but are absent from the register, and vice versa.
Are non-ISA dialects supported?
Yes. The tag convention is read from each drawing. ISA 5.1, KKS, IEC 81346, DIN 19227, NORSOK Z-DP-002, Shell DEP, Aramco SAES, and in-house operator formats are all carried through.
Where do range and set-point values come from?
From any value annotated directly on the drawing and from attached datasheets. When neither carries the value, the cell stays blank.
