Equipment and instrument tag naming convention

Overview

Instruments and equipment are identified according to their tag. The tags identify their function, location, and service. The tag naming convention differs between the generic DeltaV implementation and the GSK Wavre implementation. Each approach is explained below.

Generic DeltaV Tag Convention

A generic DeltaV tag is composed of letters and numbers and MAY take a form such as LLL-B-SSS-nn, where

B is the building number, for example 1

SSS is the system number, or vessel, for example 300

LLL is the instrument class, written as two or three letters, for example TI or XCV, and

nn is the instrument sequence number, for example 02 The separators between the instrument class and the building number, the building number and the system number, and the system number and the instrument sequence number are always hyphens. An example of a full equipment tag that uses this convention is TI-1-300-10

GSK Wavre Control Module and DST convention

The GSK naming convention differentiates between control modules and device signals by providing a unique naming convention for each. A control module tag is composed of letters and numbers and takes the form AAAAAAA_BB-CC, where

AAAAAAA is the unit name, for example FE52201

BB is the descriptive type of instrument, for example ST, and

CC is the unique identifier of element for the process function, for example E1 The separator between the unit name and the descriptive type of instrument is always a hyphen, while the separator between the descriptive type of instrument and the unique identifier of element for the process function is always an underscore. An example of a full control module tag that uses this convention is FE52201_ST-E1 A device signal tag is composed of letters and numbers and takes the form AAAAAAA-BB-CC, where

AAAAAAA is the unit name, for example FE52201

BB is the descriptive type of instrument, for example XV, and

CC is the unique identifier of element for the process function, for example C26 The separators between the unit name and the descriptive type of instrument, and the descriptive type of element and the unique identifier of element for the process function are always both hyphens. An example of a full device signal tag that uses this convention is FE52201-XV-C26
