What an equipment tag number is
An equipment tag is a stable reference used to identify a specific physical asset or equipment record. It should be compact enough for drawings and labels while remaining structured enough to support document cross-referencing.
How the generator builds tags
The default pattern combines the project prefix, equipment category, location and zero-padded sequence. The full description remains in the equipment register rather than being forced into the tag itself.
Example
An air-handling unit in the north plant with sequence 4 could produce an identifier such as EQ-AHU-NORTH-004.
Why category and location are useful
They provide context without requiring someone to know the sequence number beforehand. This is especially useful in projects with many similar motors, panels, pumps or HVAC units.
Tag governance
Once an equipment tag is issued, changing the underlying description should not normally require inventing a replacement identifier. Stable references make maintenance records and drawings easier to reconcile.
Common mistakes
Avoid two tags for the same asset. Avoid using a tag to encode too many changing properties. Keep the convention documented so different people generate compatible identifiers.
Safety and limitations
This is a documentation tool. It does not identify actual equipment automatically and does not verify field assets. Generated tags should be reconciled with the approved project register.
Frequently asked questions
Can categories be custom?
Yes. Category names are user-defined and can match the project's existing convention.
Does the generator guarantee global uniqueness?
It checks uniqueness within the current entered dataset. Existing project registers must still be checked separately.
Can this tag a panel?
Yes. A panel can be treated as an equipment category, provided that matches your documentation convention.
