Default Identifications Based on ISA-S-5.1-2009/2022
Default Identifications Based on ISA-S-5.1-2009/2022
ANSI/ISA-5.1-2009/2022 Instrumentation Symbols and Identification Standard attempts to strengthen this standard published as
ANSI/ISA-5.1-1984, and then reaffirmed in 1992. This revision extensively changes the format of ANSI/ISA-5.1-1984 (R 1992). Clauses 1, 2, and 3 are essentially the same as previously written with some additions and modifications. Clauses 4, 5 and 6 and informative Annexes A and B are new or extensively revised.
The letters in Table 4.1 - Identification letters shall have the mandatory meanings assigned except the user shall assign:
- Variables to the User's Choice letters when such letters are used
- Meaning to the blanks (undesignated letters) when additional functions or modifiers are assigned
Loop Identification letters and numbers should (informative and not mandatory) be assigned in accordance with one of the 9 Loop Numbering Schemes.
Therefore, this ISA-5.1 revision supports significant flexibility to allow users to be in full compliance with this National Consensus Standard.
However, many organizations must accommodate legacy requirements for their existing data. This application has therefore been designed to accommodate extensive administrative configurations beyond the default ISA standard configurations, as well as unvalidated user inputs that comply with the Project's maximum length requirement. Such flexibility should accommodate most project's need for consistent identification Number generation!

UserForm Group Title | UserForm Data Description |
|---|---|
Document Data | 6-Fields identifying Document Number. P&ID/Reference Drawing, Component Symbol (Instrument Index Only), Related Equipment/Drawing Number, Service Description and Upstream Line/Nozzle Number. ISA P&ID/Reference Drawings Component Symbols descriptions can be compared with detailed device descriptions from Instrument Specification forms |
Generated Identification Numbers | 3-Fields identifying Formatted Identification/Tag Number, Identification/Tag Number (unformatted) and Formatted Loop Identification Number. Formatted Loop and Tag numbers facilitate simple Index sort A to Z and compatibility with conventional database software applications |
Method and Scheme | 2-Fields identifying Loop Number Numeral Sequence Method value and Loop Numbering Scheme value |
Loop Prefix | 3-Fields identifying maximum Loop prefix length, Loop Prefix value and Loop Number Prefix Punctuation |
Functional Identification | 12-Fields identifying maximum data length and value for Measured/Initiating Variable Letter, First Letter Variable Modifier Letter, Readout/Passive Function, Output/Active Function, Function Modifier and Functional Identification Letters |
Loop Number and Suffix | 5-Fields identifying Optional Loop Number Prefix Punctuation and maximum data length and value for Loop Identification Number Numerals and Loop Number suffix |
Tag Number Suffixes | 5-Fields identifying Recommended Tag Number Punctuation and maximum data length for First Tag Number Suffix and Additional Tag Number Suffixes |
Command Buttons | 3-Command Buttons initiating Save UserForm data, Close UserForm and Reset (clear) UserForm values |
Activation of UserForms
The Instrument Specification UserForm automatically displays when a new Specification Form document is created.
The Instrument Index Data spreadsheet has a worksheet tab to open and click the command button to Open the Add Components UserForm.
An alternate method to activate the UserForm, is to open the Instrument Index Data tab and click within an empty “Keywords” (Formatted Identification/Tag Number) Column “C”, which will activate the User forms for entering and saving its data fields.
Note: This technique can be used to revise Identification Number data of an existing record, after first deleting the preexisting data, in this field.
Administration of UserForms
Administration of UserForms
An Administration UserForm worksheet is designed to enable implementation of tagging identifications of ANSI/ISA-S5.1-2009 Instrumentation, Identifications, but can also be configured to support similar identifications that use 7 or less number segments.
Such Administrative configuration activity must be performed before Project data is entered and then generally this worksheet tab is hidden to minimize unauthorized changes.
