In Instrumentation EngineerI, Tag Numbers (including Loop Numbers) are constructed from the attributes of instruments. For example, a Tag Number may be the concatenation of the relevant plant area number and its function code, suffixed or prefixed with a sequential number. Instrumentation Engineer is supplied with multiple Tag Formats, which can be edited. New Tag Formats can also be defined.
Examples of different Tag Formats for a flow transmitter:
|
FT-600 |
Typical ISA style tag format. |
|
33-FT-600 |
Typical ISA style tag format where Tag is prefixed with its plant area number (33, separated by delimiters (dashes). |
|
33FT600 |
Typical ISA style with area number but no delimiters. |
Tag Formats are selected for each AVEVA Instrumentation instrument and loop class (refer to Class Definitions for details) to define how the tag numbers of items within these classes are formatted.
To view, edit and create Tag Formats, click Setup > Tag Formats in the Project tab to display the Tag Formats window.
The window initially lists the existing tag formats for instruments.
