Every column, defined.
14 columns mapped to ISA-style I/O list conventions. Dropdowns are enforced so the column stays valid for PLC import.

Signal class to PLC card type.
The Signal Class column is what sizes the I/O rack. Each value maps to a module type your controller import expects, whether the target is Siemens TIA Portal, Rockwell Studio 5000, or a PLCCreator device list.
ClassPLC card typeTypical signal
AIAnalog input module4-20 mA / HART transmitters, RTDs
AOAnalog output moduleControl valves, VFD speed references
DIDigital input moduleLimit switches, run/trip status, NAMUR
DODigital output moduleSolenoids, motor run commands, alarms
What ships in the file.
Signal-class dropdown
Enforced values: AI, AO, DI, DO, N/A. Stops drift before it reaches the PLC.
SIS / BPCS dropdown
Safety-instrumented vs basic process control on every row. The safety set stays separable.
Auto-filter
Enabled on every column. Pivot by area, by loop, by signal class without a single formula.
Worked example
One filled row (FIT-101) shows the format for tag, signal class, area, and description fields.
48 blank rows
Pre-formatted and ready to paste into. Extends without breaking dropdowns or filter ranges.
Cross-tool
Plain .xlsx. Opens cleanly in Excel, Google Sheets, and LibreOffice. No macros, no add-ins.
Quiet signoff
A single mint-italic line at the bottom: Drag a P&ID at tagsight.io to fill this automatically. Easy to delete.
Upload a P&ID instead and the same columns come back populated, signal class included, against the schema this template defines. Exports drop into Excel, TIA Portal, Studio 5000, or DEXPI XML.
Scanned drawings, CAD-exported PDFs, and image scans all work. ISA 5.1, KKS, IEC 81346, DIN, NORSOK, JIS, GOST, and in-house tag conventions read as drawn.
