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.
DescriptionAttribute
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
WDTYPE
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.
Omitted from one-line cable markers symbols since a one-line cable
marker can represent multiple conductors, multiple wires, or core
color assignments.
RATING1
Omitted from one-line terminal symbols since a one-line terminal can
represent multiple independent terminals.
TERM01
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.
One-line symbols follow the same naming convention as schematic parent
and child symbols. For convenience, the one-line symbols provided have a
“1-” suffix. However, the symbol name does not define the symbol as a one-line
symbol. This is defined by the
WDTYPE attribute on page 325 value of “1-” on
the symbol, or a “1-1” on a one-line symbol.
■ Motor control one-line symbols are accessible from the icon menu.
■ Circuit Builder supports building motor control one-line circuits
dynamically. It allows the design of one-line circuits, with component
values and wire sizes, to conform to a given electrical code.
■ One-line component symbols can be related to parent/child counterparts
on the schematic and panel layout drawings within a project. It means
that they can be Surfed together and update each other when one is
modified.
