DescriptionAttribute
ence tag name of a related symbol shown on a different drawing type
(for example, instrument drawing or pneumatic drawing vs. electrical
schematic). 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". You can annotate the The WDTAGALT attrib-
ute carried on the schematic valve symbol with the "FY201" instrument
tag name. A WDTAGALT attribute on the symbol of the instrument
diagram carries the "SV456" tag name pointing back at the schematic
representation. AutoCAD Electrical can cross-reference between them,
do auto-update, and enable surfing from one drawing type to the
other.
Attribute used for a combined list of normally open and normally
closed contacts (if XFREFNO and XREFNC are present). Or, used for
XREF
non-NO/NC contacts (if XREFNO and XREFNC are not present).
AutoCAD Electrical underlines the closed contacts.
Optional terminal pin number attribute (ten 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 origin point of the attribute. The 'n' character is an incremented
X?TERMn
digit starting at "01" used to keep multiple wire connection point at-
tribute names unique. The "?" character position is used to identify
the preferred 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.
