DescriptionAttribute
atic). For example, an instrument drawing might be included in an
AutoCAD Electrical project drawing set with a valve marked "FY201".
On the electrical schematics, the solenoid for this instrument valve is
tagged "SV456". The WDTAGALT attribute carried on the schematic
valve symbol can be annotated with the "FY201" instrument tag name
and a WDTAGALT attribute on the instrument diagram's symbol carries
the "SV456" tag name pointing back at the schematic representation.
With this in place, AutoCAD Electrical can cross-reference between
them, do auto-update, and enable surfing from one drawing type to
the other.
Attribute that be used for a combined list of normally open and nor-
mally closed contacts (if XFREFNO and XREFNC are present) or used
XREF
for non-NO/NC contacts (if XREFNO and XREFNC are not present).
AutoCAD Electrical underlines the closed contacts.
Optional terminal pin number attribute (10 characters maximum).
Make sure to keep terminal pin number text paired with its wire
connection attributes.
TERM
Invisible wire connection attributes where an external wire connects
to the attribute's origin point. The 'n' character is an incremented digit
X?TERMn
starting at "01" used to keep multiple wire connection point attribute
names unique. The "?" character position is used to identify the pre-
ferred wire connection direction:
■ 1: wire connects to the attribute from the right
■ 2: wire connects to the attribute from above
■ 4: wire connects to the attribute from the left
■ 8: wire connects to the attribute from below
■ 0: special for motor connections
If more than 99 terminals are present on a single symbol, the 'n' value
can continue with double alpha letters/numbers such as "A0," "A1,"
"AZ," "B0" and so on.
