I. PURPOSE 


This Job Specification provides criteria for the uniform and consistent 

presentation of Instrument and Control Symbology and Identification on P&ID’s for 

the ECOPETROL Barrancabermeja Refinery Modernization Project (PMRB) - 

Barracabermeja, Colombia. 

II. SCOPE 

Instrumentation Symbols and Identification shall be in accordance with the 

Standard ANSI/ISA-5.1-2009 and the additional definitions, statements, 

requirements and exceptions described in the following sections of this Job 

Specification. These additional definitions, statements and requirements detail 

and describe the selected numbering scheme, graphic symbol, and other choices 

required by ANSI/ISA-5.1-2009. 

This Specification covers the generation of new P&IDs. It also applies to P&ID’s 

provided by packaged equipment suppliers and to tagging conventions used in the 

instrument database. 

This document provides design guidelines for the P&ID symbol and identification 

conventions associated with Instrumented Control Systems including the tagging 

used for identifying hard & soft tags. 

This document also provides several typical P&ID representations of the symbols 

as linked to field sensing devices, motor and valve controls. The intention of 

this document is to clarify how to represent Instrumentation symbols on P&IDs, 

not to provide all details how to implement the control systems.

IV. DEFINITIONS 


ANSI/ISA-5.1-2009 Instrumentation Symbols and Identification. 

“must” or “shall” A mandatory requirement for which exceptions will 

not normally be granted. 

“should” A preferred course of action for which exceptions 

will be granted for a superior course of action. 

“may” An acceptable course of action for which exceptions 

will be granted for equal or better course of 

action. 

Instrumentation Process measurement, monitoring, controlling, and 

interlocking devices and equipment. 

Instrument System A collection of instrumentation that is specifically 

designed and configured to perform a unique 

function, such as, distributed control, safety 

instrumented systems, process stream analysis, etc. 

Owner ECOPETROL or its designated representative (EPC 

Contractor, Contractor, in the sense of prime 

contractor) 

EPC CONTRACTOR Engineering, Procurement and Construction 

Contractor. FPJV or its designated representative. 

Fail Closed (FC) The characteristic of an automated valve that 

results in the valve closing as a result of specific 

malfunctions, including loss of signal or motive 

power (Reference ISA S5.1.). 

Fail Indeterminate (FI) The characteristic of an automated valve that 

results in the valve moving to an unknown position 

as a result of specific malfunctions, including loss 

of signal or motive power. Some automated valves 

will not stay at the last position upon failure and 

will instead move with the process differential 

pressure. Additional equipment may be needed to meet 

the definition of FC, FO or FL. (Reference ISA 

S5.1.). 

Fail Locked (FL) Last Position: The characteristic of an automated 

valve that results in the valve remaining in the






last (locked) position as a result of specific 


power. Automated valves may fail indeterminate 

without additional equipment. (Reference ISA S5.1.). 

Fail Open (FO) The characteristic of an automated valve that 

results in the valve opening as a result of specific 


power (Reference ISA S5.1.). 

Hand Switch (HS) Any operator manipulated discrete control device, 

including hardwired panel switches and software 

points. 

Interlock A system that, in response to a predetermined 

condition, initiates a predefined action. Typically 

comprised of binary (on - off) signals and logic 

used for process control, sequencing or protective 

interruption of normal process control functions. 

Protective interlocks are typically further defined 

as being either safety related or commercial (asset 

or production protection) related. 

Logic solver The control equipment that performs the logic 

function. It can be either hardwired (e.g., relays) 

or Programmable Electronic Systems (e.g., DCS or PLC 

based, including dual or triple redundant 

microprocessors). 

Loop Number A number that identifies a related collection, or 

group, of instrument devices and control functions. 

Piping & Instrumentation 

Diagram (P&ID) 

A detailed graphical representation of a process 

including the hardware and software (e.g. piping, 

equipment, instrumentation) necessary to design, 

construct and operate the facility. Common synonyms 

for P&ID's include EFD's (Engineering Flow 

Diagrams), UFD's (Utility Flow Diagrams) and MFD's 

(Mechanical Flow Diagrams). 

Tag Number Unique identification number for an individual 

instrument device or control function





V. GENERAL 


A. Instruments shall be identified (tagged) by a system of letters and numbers 

generally in accordance with the ANSI/ISA-5.1-2009 and the additional 

definitions, statements, requirements and exceptions described in the 

following paragraphs. 

B. Each instrument, device or component in the project shall have a unique alphanumeric 

tag number using the following style: 

XXXXX - UU NNN Z Z 

| | | | | 

| | | | Tag Number Suffix (1 letter) 

| | | | 

| | | Loop Number Suffix (1 letter) 

| | | 

| | Consecutive Number, 3 digits 

| | 

| Unit Identifier, 2 digits 

| 

Functional Identification (max 5 letter left justified) 

C. The Functional Identification will use a system of letters to classify the 

instrument, device or component functionality and will use up to five (5) 

letters left justified (see section VI). The Unit Identifier defines the unit 

with which the instrument/ device/ component/ loop or system is associated. 

The consecutive number will establish a loop identity for the instrument, in 

general, will be common to other instruments, devices or components of the 

loop of which is a part. The Loop and Instrument number suffixes are sometimes 

added to complete the instrument identification (Based on ANSI/ISA-5.1-2009 

Annex A). 

D. The Loop Number Suffix may be added to a Loop Number to identify identical 

loops on identical equipment in the same processing unit when the service or 

equipment is assigned the same equipment identification number with a suffix, 

such as reactors, heat exchangers, and pumps. The Loop Suffix shall be one 

letter and shall be located after the numeric component of the tag number. 

E. The Tag Number Suffix shall be one letter and shall be located after the loop 

number suffix if it is used or after the numeric component of the tag number 

if the loop number suffix is not used. The tag number suffix may be added to 

Instrument Tag Numbers in the loop to designate two or more similar devices or 

functions: 

1. Case 1 – in different services, such as control valves that direct flow to 

different places or auxiliary devices, such as those that perform different 

functions.






2. Case 2 – in the same service, such as control valves that direct flow to 

the same place or auxiliary devices, such as those that perform the same 

function. 

F. For the new Units, the Unit identifier will be a two digit number as shown in 

the table V.2 and the consecutive number will be a three-digit number between 

001 and 999. 

G. For existing Units, the unit number will be a two-digit number. For process 

areas with similar Unit Number (i.e. U-200 and U-2000), a leading zero shall 

be included as part of the unit identifier. The consecutive number will be a 

three-digit number limited by the numerical sequence of the similar unit 

number: i.e. for process areas U-200 and U-250, the consecutive number will be 

between 000 and 499 for unit U-200 and will be between 500 and 999 for unit U- 

250. In this case, the numeric component of the tag number (UU NNN) shall be 

provided by the Owner. See examples below:

Remarks 

I. Where ANSI/ISA-5.1-2009 offers alternate methods of presentation, the project 

practice is to use the method requiring the fewest symbols. Symbols will not 

be shown for the following: 

1. Valve positioners. Valve positioners will not be part of the Instrument 

Index. They shall be identified and included in the instrument database and 

P&ID’s only if they are provided as standalone instruments or if they need 

to be installed distantly from the related final element. 

2. Balloons identifying flow primary elements. Flow primary elements will be 

part of the Instrument Index. 

3. Local process variable indicators on transmitter outputs, unless it is 

intended to designate a special location for the indicator, as shown by a 

note next to the tagging balloon. 

4. Square root extraction signal conditioning. Unless noted otherwise on the 

P&IDs, square root extraction of head meter type flow instrumentation is 

assumed to be performed in the transmitter. 

J. Transmitters with integral indicators shall be identified with letters (FT, 

PT, LT, TT, AT). 

K. Control Valves shall be identified with letters (FV, PV, LV, TV, etc). New 

positioners for existing valves shall be added to the instrument database 

under the same valve tag with a comment “ Existing Valve – New Positioner” 

L. I/P Converters and Electro-pneumatic positioners shall be identified with 

letters FY, PY, LY, TY, and AY and shall be included in the instrument 

database and P&ID’s only if they are provided as standalone instruments or if 

they need to be installed distantly from the related final element. 

M. If it is required to use multiplexers or wireless transmitters, they shall be 

identified on P&ID and included in the instrument database. See examples 1 and 

2 below:

Figure V.1. Example 1 

TE 

82004 

Figure V.1. Example 2 

N. Functional identification of an instrument shall be made according to its 

function and shall not be based on its construction. Thus a differential 

pressure transmitter used for flow measurement shall be tagged as “FT” or a 

pressure transmitter on an atmospheric tank to measure its level shall be 

tagged as “LT” and so on. 

O. The numeric component of Tag Numbers may be duplicated within the same unit 

area (e.g. FT -63001 and LT -63001 have a different first letter but have 

the same numeric component, 63001). 

VI. FUNCTIONAL IDENTIFICATION 

A. The functional identification of an Instrument shall be a system of letters 

generally in accordance with the ANSI/ISA-5.1-2009, extracts from which 

follow. Minor modifications have been made. 

TI 

82004 

TT 

82004






B. The functional identification of an instrument will consist of letters from 

Table VI.1, and will include one first-letter, covering the measured or 

initiating variable ([L]=Level, [F]=Flow, [P]=Pressure, etc.) and the 

succeeding letter covering the functions of the individual instrument 

([T]=Transmitter, [C]=Controller, [I]=Indicator, etc.). Additional letters can 

be included as modifiers of the first of succeeding letter previously 

mentioned. Modifiers shall be consistently used wherever applicable. Use 

maximum five (5) letters as functional identification. 

C. The modifiers [R]=Run / [S]=Stop and [C]=Close / [O]=Open for the succeeding 

letters shall be used for the Run/Stop and Close/Open signals rather than 

suffixes (e.g. the Run/Stop push button shall be tagged as HSR -82001 and HSS 

-82001 instead of HS -82001A and HS -82001B). 

D. Control Signal to auxiliary electrical devices like motors interposing relays, 

shall use [Y] rather than [M] or [X] as first-letter (e.g. YY -82001 instead 

of XY -82001). 

E. Auxiliary devices like solenoid valves shall be tagged based upon their 

initiating loop and not upon their output loop. 

F. All Control Functions shall include the modifier [I] (e.g. FIC -82001 instead 

of FC -82001). 

G. Safety valve, pressure relief valve, safety relief valve, vacuum relief valve 

and thermal relief valve shall use the functional identification [PSV]. An 

Identification / Tag Number Suffix could be added to Identification / Tag 

Numbers of these valves in case of a multiple relief valve system scenario. 

H. The Deviation Alarm is an alarm generated when the difference between two 

analog values exceeds a limit (e.g., deviation between primary and redundant 

instruments or a deviation between process variable and setpoint). The general 

deviation alarm between redundant transmitters shall use the functional 

identification [*AD*], i.e. the high deviation alarm for the transmitters PT 

-82501A, PT -82501B and PT -82501C shall be PADH -82501. 

I. The Motor Operated Valves for the Offsite Area (U-7100) and the existing units 

could be identified [MOV] to keep consistency with the existing tag naming 

convention in the ECOPETROL Barrancabermeja Refinery. 

J. The Tank Gauging System and Motor Operated Valve host stations could use the 

functional identification [UK]. 

K. The Level Transmitter part of a Tank Gauging System shall use the functional 

identification [UT] instead of [LT]. This level transmitter usually gets 

multiple process variables (level, pressure and temperature) for the tank 

gauging system. 

L. The water level transmitter part of the existing Tank Gauging System could use 

the functional identification [NT] or [LT] in accordance with tag naming 

convection existing unit.






M. The Variable Modifier [Z] shall be used to identify components of the Safety 

Instrumented Systems. 

N. Readout/Passive Function indicate [I] applies to the analog or digital readout 

of an actual measurement or input signal to a discrete instrument or a 

distributed control system's video display unit. It should apply to field 

signal indicators (4-20 mA, 0-100%, engineering units with low accuracy) and 

remote display indicators (engineering units with high accuracy). 

O. The attachment A includes a table with the allowable first letters for single 

and multi-input components. 

P. The Measurable Variable [Y] should be used for sequence controlled logic which 

is associated with batch control (i.e. Coke Drum Valving sequence). 

Q. Refer to the Job Specification 123939-60A18, Control Systems-Electrical 

Interface for Motor Control Tagging convention. Typical tagging for motor 

control is shown in the legend sheets, Attachment C.

page. 

(Reference ANSI/ISA-5.1-2009 Section 4)






Notes for Table VI.1 -- Meanings of Identification Letters 

(Reference ANSI/ISA-5.1-2009 Section 4) 

1. A user's choice letter is intended to cover unlisted meanings that will be 

used repetitively in a particular project. If used, the letter may have one 

meaning as a first-letter and another meaning as a succeeding-letter. The 

meanings need be defined only once in a legend, or otherwise, for that 

project. 

2. The unclassified letter [X] is intended to cover unlisted meanings that will 

be used only once or to a limited extent. If used, the letter may have any 

number of meanings as a first-letter and may have any number of meanings as a 

succeeding-letter. Except for its use with distinctive symbols, it is 

expected that the meanings will be defined outside a tagging balloon on a 

P&ID. For example, XR -00002 may be a stress recorder, XR -00003 may be a 

vibration recorder, and XX -00004 may be a stress oscilloscope. 

3. First-letter [A] for analysis covers all analyses that are not listed in Table 

2 and are not covered by a user's choice letter. It is expected that the type 

of analysis in each instance will be defined outside a tagging balloon on a 

P&ID. 

4. A pilot light that is part of an instrument loop shall be designated by a 

first-letter followed by succeeding-letter [L]. For example, a pilot light 

that indicates an expired time period may be tagged [KL]. However, if it is 

desired to tag a pilot light that is not part of a formal instrument loop, the 

pilot light may be designated in the same way. Except motor status lights 

which shall be not tagged [XL], regardless of the contact source. See note 2 

above. Status lights for valves shall be tagged [ZLO] for the open position 

and followed by [ZLC] for the closed position.





VII. LOOP IDENTIFICATION 

VIII. SYMBOLS 


A. The loop identification of an instrument shall have a unique alpha-numeric 

loop number using the following style: 

X - UU NNN Z 

| | | | 

| | | | 

| | | | 

| | | Loop Number Suffix (1 letter) 

| | | 

| | Consecutive Number, 3 digits 

| | 

| Unit Identifier, 2 digits 

| 

First Letter - Functional Identification (max 2 letter left justified) 

B. Refer to section V.General on this document for the completed description of 

each part on the Loop Identification. 

C. A Loop Number Suffix may be added to a Loop Number to identify identical loops 

on identical equipment in the same processing unit when the service or 

equipment is assigned the same equipment identification number with a suffix, 

such as reactors, heat exchangers, and pumps. The Loop Suffix shall be one 

letter and shall be located after the numeric component of the Loop 

Identification Number. 

D. Because of the critical nature of the safety relief devices, [PS] is 

considered as Measured/ Initiating Variables in the Loop Identification 

Number. 

A. It is not the intention of this standard to list all symbols or combinations. 

ANSI/ISA-5.1-2009 lists many more. Symbols not specifically depicted in the 

Job Specification 123939-60A3 shall be based on ANSI/ISA-5.1-2009. 

Instrumentation Symbology and details are also shown on the attached Legends 

and Symbols drawings in Attachment C. 

B. Control valve positioners and control valve electric-to-air converters will be 

shown. (Reference ANSI/ISA-5.1-2009 Table 5.4.3 drawings 2 and 5). These 

devices may be identified on P&ID’s just in the cases specified in the 

paragraph V.I.1 in this document. 

C. In addition, various notations may be used on individual symbols. For 

example, the letter "V" just outside the circle can indicate an item supplied 

by a package vendor, or the letters "LP" can indicate a local panel mounting.






See Legend Sheets in attachment C. These letters shall be placed at the lower 

right of an instrument balloon as follow: (V) and (LP). 

D. The actuator action (FO, FL, FC) in the event of actuating medium failure 

shall be shown on the P&ID’s, close to the control valves. (Based on 

ANSI/ISA-5.1-2009 Table 5.4.4 Method A). 

E. Most of instruments balloons used for tagging shall be solid line on P&ID's. 

These instruments may be repeated on auxiliary flow diagrams (AFD's), in 

phantom to provide a clear functional understanding. If it is required to show 

the same balloon in two different P&ID’s, just one of them shall be shown with 

solid line and the other ones shall be shown with dash lines. 

F. An arrow head shall be used when required to clarify the direction of the 

signal for all line types. It shall be shown at the end of the line where it 

enters a device. 

G. All alarm/trip values (i.e. temperature, flow, pressure, etc.) shall NOT be 

shown on P&IDs but shall be provided as part of the instrument database. 

H. The circle within a square shall represent the Primary shared-display, sharedcontrol 

system devices or functions. If the system is other than the 

primary DCS device or function, it can be identified as notation outside of 

the bubble; such as PLC-1. 

I. The rotated square within a square shall represent the Safety Instrumented 

System devices or system. If the system is other than the primary SIS device 

or function, it can be identified as notation outside of the bubble, such as 

BMS-1. 

J. The type of elements for temperature primary elements and level transmitter 

shall be identified on the EFD according to the instrument measurement 

notation table in the attachment B on this Job Specification. 

K. The Tank Gauging System and Motor Operated Valve host stations shall use the 

Computer System and Software Symbol shown in the ANSI/ISA-5.1-2009, Table 

5.1.1 Symbol No 3 Column C.
