• PLC -name of PLC system (could be FGS, TGS or PLC) • I -PLC logic

• xxx -Serial number, ranging from 001 to 999

The full name of PLC logics to be shown in the PLC logics shall have the following format:

I-hh-xxx

where:

• xxx -Serial number, ranging from 001 to 999 11.3.1 Numbering Procedure

Due to the implementation of the numbering code in SPI Tools, the prescriptions of the present specification are mandatory and deviations are not allowed. The use of the letters and digit codes is strictly restricted to the ones clearly listed in ATTACHMENT 3, tables IV, V, VI and VII. Codes not listed in the mentioned tables cannot be used unless previously agreed with EMPLOYER/CONTRACTOR.

Measured or initiating variable letter code and function letter code

For measured or initiating variable letter a single capital letter only shall be used. For function letter code a maximum of five (5) letters shall be used.

For function letter code capital letter only shall be used.

The measured or initiating variable letter shall identify the process condition/property measured or initiating variable, as per column 2 of the Table I in ATTACHMENT 3. The measured or initiating variable letter shall be followed by the function letter code without hyphens (refer to ATTACHMENT 3 - Table I, columns 3, 4 and 5).

Where there are two or more succeeding letters, the priority of lettering shall be in the sequence TQIBRCSZAV e.g. PICA not PIAC, FQI not FIQ etc

For computing functions the succeeding letter Y shall be used (HY where operator access is required) with qualifiers shown outside the balloon (refer to ATTACHMENT 3 - Table II).

The relevant primary function letter shall be added to the Y, e.g. FY.

Loop where initiating variable is not a process variable may use a letter code of more than one character (e.g. UV, XV, MOV , PSV, etc.).

Refer to DOC. No. 3034-00-ED-IN-JSP-70087 “Job Specification for Smartplant Instrumentation”.

Measured or initiating variable letter available codes and function letter available codes are summarized in the ATTACHMENT 3 - Table IV.

xxx I PLC

Unit identification

Two (2) digits code only shall be used.

Process units, auxiliary units and offsite units identification numbers are summarized in the ATTACHMENT 3 - Table VII.

Serial number

For numbers three (3) digits shall be used (001 up to 999), with the possible addition of one letter to identify specific functions of components which otherwise would have the same tag, e.g.:

YHS-xx-001M and YHS-xx-001P respectively for Maintenance and Process Override Switches of the transmitter YZT-xx-001 connected to ESD.

For the not-licensed units, numbering shall be parallel, i.e. a numerical sequence will start for each instrument function code first letter 'Y' and for each process unit designation 'xx'.

All instruments part of the same loop shall have the same serial number 'zzz'. For numbering ranges reference is made to the ATTACHMENT 3 - Table VI.

The process instruments and process loops serial number relevant to the Licensed Units shall follow the numbering philosophy specified in this procedure and not the Licensor philosophy (refer to ATTACHMENT 3 - table VII for the Licensed Unit list).

Suffix

In general. for suffix letter a single capital letter and digits shall be used. The suffix must not exceed three (3) letters/digits length.

Suffix letter shall be used only for in case two or more instruments are required to satisfy the same process requirement.

Such instruments shall be suffixed as follows:

• Level Gauges: A = Top, B/C = Lower

• Transmitters (general): A = High Range, B = Low Range • Transmitters (2ooN): A, B, . . , N

• Indicators on transmitter output: NO SUFFIX= Control Room, A=Local • Valves: A = Positive (Pressure/Heat),

B = Negative (Vent/Cool)

• Chromatographs: A1÷An = First Stream Components (components from 01 to 99)

B1÷Bn = Second Stream Components

(components from 01 to 99)

Z1÷Zn = Last Stream Components (components from 01 to 99)

In general no suffix letter shall be used in the Loop numbering tag numbers. 11.3.2 Instruments in Packaged Units

Instruments supplied in packaged units shall be tagged according to the above mentioned criteria and within the serial number range shown in ATTACHMENT 3 - Table VI.

However, due to presence of more packaged supplies in the same unit, it is necessary to assign restricted number ranges for each package supply. This range assignment will be defined at a later stage by Contractor.

11.4 Symbols

It is not scope of this specification to list all symbols or combinations of them.

When required, these shall be developed using this specification as a basis, and referring to ISA standard. To clarify functionality, the information flow direction may be shown by arrows on signal line symbols; the qualification of the function (for example to indicate process condition or computation) shall be located next to the balloon (right hand side).

Where control signals split across P&ID sheets, the signal lines shall route to a flag located at the left or right margin of the drawing; the flag shall identify the continuation P&ID sheet with the tag number/service description detailed local to the flag.

11.4.1 Typical of instrument representation

Unit identification may be omitted on P&IDs related to the same unit; in such case a note on P&ID shall clearly specify that: “All instruments shown on this P&ID are part of the unit ‘xx’ ”.
