Overview of parent and stand-alone component
attributes (TAG1)
AutoCAD Electrical puts the component's tag name on this attribute, names
like "PB101" or "CR-55" (24 characters maximum). The default value you assign
to this attribute definition at the library symbol level (i.e. symbol's ".dwg" file
opened and displayed in AutoCAD) becomes the family code character string
AutoCAD Electrical uses to build the component's tag name when the block
is inserted into your wiring diagram. This default value character string is used
as the Family Code (%F) portion of the drawing's tag format code you set up
in the Drawing Properties
➤
Components dialog box (example %F%N).
For example, use "PB" for a default value of the attribute definition TAG1 if
the family name you want AutoCAD Electrical to use is "PB" (examples:
"PB100", "100-PB", "PB4-100"). Note that this family name can be overridden
at component insertion time, a later edit, or automatically by use of the
"wd_fam.dat " mapping file.
NOTE
If the TAG1 attribute carries no default value then AutoCAD Electrical will
use that symbol's FAMILY attribute value.
Overview of child component attributes (TAG2)
AutoCAD Electrical puts a copy of the parent component's tag name on the
child component attribute (TAG2). During the AutoCAD Electrical tagging
operation, AutoCAD Electrical takes the parent coil's tag name (carried on its
TAG1 attribute) and copies it to this contact's TAG2 attribute. If no parent tag
is found then AutoCAD Electrical displays the attribute definition's default
value.
Copy attributes
COPYTAG is the optional TAG copy attribute. When AutoCAD Electrical
updates a TAG1 of TAG2 attribute, it also looks for and updates any COPYTAG
attributes present on the symbol with a copy of the TAG text. A special
replaceable parameter, "%T", can be encoded onto the COPYTAG attribute
definition's prompt value. This allows for adding a suffix and/or prefix to the
TAG text. If you need more than one extra TAG copy on a symbol, name the
attributes COPYTAG01, COPYTAG02, etc. If there is no prompt value encoded
