Instrument index.
The facility-wide master list. One row per instrument tag, read as drawn in any tag convention (ISA 5.1, KKS, IEC 81346, NORSOK, or an in-house standard) and deduplicated across every P&ID and datasheet in the project. Each row carries the source sheet, the loop, the linked equipment, and any range or set point the drawing or datasheet supplied.
Three drawings included on a new account.
One row per tag, deduplicated.
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.
The instrument index is built from every P&ID in the facility scope, deduplicated, then enriched with range and set-point data from any datasheets you upload.

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. A multi-vendor facility with mixed conventions produces a single merged index.
