Attribute Requirements
Overview of schematic attributes
The following are attribute requirements for various categories of schematic
symbols. Note that some attributes are used in multiple categories.
Schematic parent and child components
DescriptionAttribute
(Parent only) Attribute for required component tag name (64 charac-
ters maximum). The default value you assign to this attribute definition
TAG1
becomes the family code character string AutoCAD Electrical uses to
build the component's tag name when the block is inserted into your
schematic. 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 Properties dialog box.
Example: the TAG1 attribute definition on the symbol carries a default
value of "MCR" and the drawing's tag format is "%F%N" where %N
is the placeholder for the line reference number or next sequential
number. As each instance of this symbol is inserted, it will automatic-
ally be assigned a tag name with an "MCR" prefix tacked on to the
reference or next sequential number.
NOTE When a component is marked with a fixed tag, this attribute
name is automatically changed with a "F" suffix (i.e. TAG1 TAG1F).
(Child only) This is a copy of the parent component's tag name (64
characters maximum). If no parent tag is found then AutoCAD Elec-
TAG2
trical displays the attribute definition's default value (ex: "MCR" or
"PB" or "X").
(Parent only) Alternate to using a single TAG1 attribute (64 characters
maximum). This allows the component tag name to be split into two
TAG1_PART1
TAG1_PART2
pieces (example: two lines - "MDOT" on first line and "123" on the
