About Attributes for One-Line, Hydraulic, and P&ID Symbols

WDTYPE attribute

The WDTYPE attribute value specifies a component category for a non-schematic, non-panel component. It is limited to four characters and can be user-defined. For some schematic reports, you can select a component category for the report based on the WDTYPE value.

Note:

AutoCAD Electrical reserves all two-character values. User-defined values must be three or four characters long.

AutoCAD Electrical uses the following WDTYPE attribute values.

Attribute Value	Symbol category
1-	One-line
1-1	One-line bus-tap
HY	Hydraulic
PN	Pneumatic
PI	P&ID

One-line symbols

A one-line symbol can be a parent, child, or terminal. These one-line symbols use the same attributes as the schematic parent, child, and terminal symbols but with the following exceptions.

Attribute	Description
WDTYPE	The attribute must be present and carry a value of “1-” to indicate it is a one-line symbol, or “1-1” for the one-line bus-tap symbols. A bus-tap symbol is used to mark the beginning of a one-line circuit. Schematic symbols do not carry this attribute or have the attribute but with a blank value.
RATING1	Omitted from one-line cable markers symbols since a one-line cable marker can represent multiple conductors, multiple wires, or core color assignments.
TERM01	Omitted from one-line terminal symbols since a one-line terminal can represent multiple independent terminals. If a TERM01 attribute is added to a one-line symbol and carries a non-blank value, it can be edited in the Insert/Edit Terminal Symbol dialog box. However, terminal number text on one-line terminal symbols is not linked back to terminal number assignments on schematic or panel terminal representations. Note: Terminal Strip Editor does not process one-line terminals.

Hydraulic and P&ID symbols

Attribute	Description
TAG1	Attribute for required component tag name (64 characters maximum). The default value you assign becomes the family code character string AutoCAD Electrical uses to build the tag name of the component when the block is inserted into your wiring diagram. This default value character string is used as the Family Code (%F) portion of the tag format code of the drawing you set up in the Drawing Properties Components dialog box (example %F%N).
INST	Optional attribute for component installation code (for example, "MACH1"; 24 characters maximum).
LOC	Optional attribute for component location code (for example, "FIELD"; "JBOX2"; 16 characters maximum).
FAMILY	Invisible attribute that carries the components family type (for example, "FI", "INS"; eight characters maximum). Generally, the default value of the FAMILY attribute definition is the same as the default value for the TAG1 or TAG2 attribute of the component. A generic child device can be linked to any type of parent symbol when the Family attribute value of the child is left blank. AutoCAD Electrical fills it in on the fly with the FAMILY code of the parent when the link is made.
CAT	Invisible attribute for optional catalog number (60 characters maximum).
MFG	Invisible attribute for optional manufacturer name or code (24 characters maximum).
ASSYCODE	Invisible attribute for optional subassembly code that causes AutoCAD Electrical to extract subassembly items into BOM reports (60 characters maximum). AutoCAD Electrical, not the user, sets the value for this attribute.
RATING1	Optional attribute for rating/value text (60 characters maximum).
DESC1, DESC2, DESC3	DESC1: Description, first or only line of description text (60 characters maximum). DESC2: second line of description text. DESC3: third line of description text.
WDTYPE	Optional attribute used to define the component category. 1- = one-line 1-1 = one-line bus-tap HY = hydraulic PI = P&ID PN = pneumatic Note: The WDTYPE value can be a user-defined value. AutoCAD Electrical reserves all two character values. User-defined values must be three or four characters long.
WDTAGALT	Attribute carried on a parent symbol used for setting up a "peer-to-peer" relationship (64 characters maximum). It stores the cross-reference 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 attribute 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.
XREF	Attribute used for a combined list of normally open and normally closed contacts (if XFREFNO and XREFNC are present). Or, used for non-NO/NC contacts (if XREFNO and XREFNC are not present). AutoCAD Electrical underlines the closed contacts.
TERM	Optional terminal pin number attribute (ten characters maximum). Make sure to keep terminal pin number text paired with its wire connection attributes.
X?TERMn	Invisible wire connection attributes where an external wire connects to the origin point of the attribute. The 'n' character is an incremented digit starting at "01" used to keep multiple wire connection point attribute 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.
