Notes
What is a P&ID tag extraction template?
A structured Excel template for recording every tag extracted from P&IDs. Columns cover tag number, ISA 5.1 instrument type, P&ID reference with sheet and revision, loop assignment, line number, equipment reference, safety classification per IEC 61511, design conditions, material, signal type, and range / set point. Used as the baseline for building instrument indexes, tag registers, I/O lists, and equipment lists for EPC projects.
Can Pathnovo auto-populate this template?
Yes. Pathnovo extracts tag data from P&IDs and populates this template automatically with 99.5% contractual accuracy. Reference benchmark: 10,247 tags across 600 P&IDs processed for McDermott with zero QA rejections. Processing time: minutes per drawing. See /solutions/pid-extraction/tag-extraction for the full workflow.
What ISA 5.1 tag types does this template support?
Full ISA 5.1 symbol coverage: flow (FI, FT, FE, FIC, FCV, FY, FQI), temperature (TI, TT, TIC, TCV, TY), pressure (PI, PT, PIC, PCV, PY, PSV, PSE), level (LI, LT, LIC, LCV, LY, LG), analysis (AI, AT, AIC, AY), control valves, safety valves, rupture discs, flame arresters, actuators, transmitters, and all modifier symbols per ISA 5.1 Tables 2-1 through 2-12. DIN, BS, JIS, and company-specific conventions also supported via the Functional Identification Letters column.
How do I count tags on a P&ID before procurement?
Three options: (1) Manual count using this template, which takes 2-4 hours per P&ID for a typical complex drawing; (2) Use the free Pathnovo P&ID Tag Counter tool at /resources/tools/pid-tag-counter for a quick estimate; (3) Pathnovo managed service for full extraction with 99.5% accuracy at $95 / drawing. For projects with 100+ P&IDs, managed service is economically compelling over manual counting.
Is this template compatible with Hexagon SmartPlant or AVEVA?
Yes. Column structure maps to SmartPlant Instrumentation (SPI) and AVEVA Instrumentation import formats. For operators already running these platforms, Pathnovo delivers directly in the native import format. See /alternatives/smartplant-instrumentation and /alternatives/aveva-instrumentation.
What is the relationship between tag extraction and instrument index?
Tag extraction is the first step; instrument index generation is the complete deliverable. Tag extraction produces the raw tag register (tag, type, P&ID reference, location). Instrument index adds datasheet data, loop assignments, I/O configuration, SIL classification, and downstream system integration (SAP PM / Maximo). Pathnovo's full instrument index workflow at /solutions/instrument-index-automation uses tag extraction as Step 1.
