Description Attribute
This attribute can be used in two different ways. It can be used for a
combined list of normally open and normally closed contacts. Auto- XREF
CAD Electrical underlines the closed contacts. If XREFNO and XREFNC
are present then this XREF attribute will be used to carry undefined,
non-NO/NC references.
NOTE If XREF is not present then non-NO/NC contacts are included
with the XREFNO annotation.
Invisible attribute present when the symbol is a contact. The value of
this attribute is the contact's de-energized state (ex: "NO" or "NC" or CONTACT
any text string with an embedded "NO" or "NC" such as "NO-TC".
Use "NULL" as the contact attribute's value if you want to exclude the
contact from being included in any AutoCAD Electrical cross-reference
text annotation.)
Attribute to mark switch position text where "n" is the position number
digit (POS1 through POS12; 24 characters maximum). You can leave
the default value blank and then fill it in at component insertion time. POSn
Optional contact state character string to denote relationship between
switch positions and open/closed contact state. It is for display only. STATE
You can leave the default value blank and then fill it in at component
insertion time.
Optional rating / value attribute text where "n" is a digit starting with
"1" (60 characters maximum). AutoCAD Electrical supports up to 12 RATINGn
RATINGn attributes (for example, RATING1 through RATING12) on
the component symbol. These assignments can be pulled into various
AutoCAD Electrical reports.
Optional invisible attribute that allows AutoCAD Electrical to automat-
ically tie in dashed link lines between related components (instead X?LINK
of cross-reference annotation). The "?" is a digit that indicates the
preferred link line connection direction and follows the wire connec-
tion convention (see X?TERMn below).
(Parent only) Optional invisible attribute carried on a parent symbol
for storing the allowed contact pin list for the parent's child contacts PINLIST
