3.0 INSTRUMENT IDENTIFICATION

3.1 For administrative purposes all instrument components and functions shall be identified by means of a

unique tag number. A tag number is a combination of letters and numbers used to uniquely identify

instrument components and instrument functions. A combination of electrically interconnected

instrument components and functions performing a basic operation is called an instrument loop and

shall be identified by means of a unique loop number. A loop number is the unique identification of a

combination of instrument components and/or instrument functions performing a dedicated instrument

safeguarding, control and/or monitoring function.

3.2 Traditionally, all components/functions shall be shown in individual balloons:

TE-0101 Temperature element (e.g. RTD)

TT-0101 Temperature transmitter

TIC-0101 Temperature controller

TV-0101 Control Valve

Components in the instrument index are similar to those above with format mentioned in paragraph 3.3.

3.6 SEQUENCE NUMBER

For each measured or initiating variable the loop number sequence will restart. Example: Loop 110P-0103

and loop 110L-0103 may coexist.

3.7 LOOP NUMBER AND TAG NUMBER UNIQUENESS

To maintain identification uniqueness all noncalibrated / Local instruments (*) the numbers shall not

be repeated for the instruments having same measured variable. The nos for transmitters (PT) and local

instruments like Relief valve (PSV), Pressure Gauge (PI) shall not be repeated.

Note: -.* Typical examples of noncalibrated / Local Instruments:

Relief valves/bursting discs.

Self-regulating valves (temperature and pressure).

Level gauges, Temperature Gauges, Pressure gauges, Restriction Orifices, Test

Thermowells, Test Points etc.

3.8 All Field Gauges shall use the function letter “I”, e.g. Pressure Gauge 110PI-0102, see example

S-04 and 110LI-0102, see example S-02, until unless it is specified.

3.9 PRESSURE POINTS

Process pressure points shall not be provided with an instrument loop or tag number.

3.10 TRANSMITTER INTEGRAL INDICATORS

Integral indicators are generally not shown; the use of indicators shall be as described in Instrumentation

design basis. Loop Powered indicators wherever required shall be shown in P&IDs.

3.11 MASS-FLOW LOOP

Where a mass-flow computation is done by the measurement of flow with pressure and temperature

compensation, each individual part of the overall loop (flow, pressure and temperature) shall have a unique

Number e.g. 110F-0232, 110P-0232 and 110T-0232, with the control valve being tagged as part of the flow

Loop (110FV-0232). See example L-15. Loop Number shall be same for all such components if possible.

3.12 RELIEF VALVES

Where there are two (2) or more relief valves installed (e.g. vessel pressure relief) for the same service, then

the tag numbers shall have an alphanumeric suffix, e.g. 110PSV-0107A and 110PSV-0107B. Installed spare

valves shall have "S" suffix.

3.13 SELF-REGULATING VALVES

Self-regulating valves shall have a tag number format using e.g.110PCV-0112. See example S-08.

3.14 CONTROL VALVES

3.14.1 Where a valve is used in a "control only" loop, the valve will have the same identifier and loop sequence

number as the main function component. See examples L-03, L-04, L-06.

3.14.2 Electropneumatic positioners are fitted to control valves, these will not be assigned a tag number but

will be considered to be part of the valve.

3.14.3 When a control valve is part of a cascade loop, the valve tag number shall have the same tag number type

as the secondary control loop. See example L-05.

3.15 ON-OFF VALVE STATUS INDICATION

In general Limit switches on ON-OFF valves shall have a unique loop and tag number which shall be

derived from the valve tag number. See examples L-09.

3.16 SOLENOID VALVES

3.16.1 The tag number for a solenoid valve connected to an on/off valve shall have the same type letter and loop

sequence number as the valve, e.g. valve 110XV-0103, solenoid valve 110XY-0103. See examples L-10.

3.16.2 The tag number for solenoid valve connected to a control valve (in normal operation, but which is also

included in a safeguarding loop), shall have the number that of the valve e.g. valve 110LV-0140, solenoid

valve110LY-0140. See examples L-06.

3.17 ID/IS BLOCKS

3.17.1 Where a ID/IS block is associated with solenoid valve connected to a control valve, the ID/IS block shall

have a unique tag number and not that of the valve and solenoid valve, e.g. valve 110LV-0140, ID/IS block

110I-0210, solenoid valve 110LY-0140. See example L-06.

3.17.2 Trip signals to motors / MOV’s are outputs from the ESD (i.e. ID/IS -blocks) and shall be tagged as per

ANNEXURE - 1: MOTOR CONTROL SCHEMES &

ANNEXURE - 2: MOV CONTROL SCHEMES. Please refer the same for all signals of Motor and MOV.

3.18 TAGGING OF SIGNALS BETWEEN DCS AND ESD

The instrument index listing shown below each example in this document is based on the requirement for

each instrument component and/or function to have a unique tag number.

For signals which run between two (2) systems (e.g. ESD and DCS), two (2) line items has been introduced

in the instrument index listings; one(1) line item for the signal leaving the system 1(e.g. ESD) and one (1)

line item for the signal received by the system 2(e.g. DCS).

A similar approach may be used for symbols running between other systems (i.e. use of a suffix for signals

in one of the systems). All ESD inputs from Field shall have indication in DCS via Serial Link. Example L-09.

ESD = Safeguarding System (ESD). DCS = Distributed Control System.

3.19 KB BLOCKS

The KB blocks should be used for time sequence control only (see examples L-11). Input and output

signals shall be tagged in analogy with input and output signals from ID/IS blocks.
