About schematic terminals
AutoCAD Electrical supports two types of relationships for terminals:
schematic-to-schematic and schematic-to-panel.
NOTE Since one-line terminal symbols likely represent multiple, independent
terminals, they cannot be associated to other schematic or panel terminals. A
one-line terminal must be updated manually. A one-line terminal symbol is defined
by a
WDTYPE attribute on page 325 value of 1-.
Schematic-to-Schematic
The schematic-to-schematic relationship defines separate schematic terminal
symbols as one multi-level (also referred to as multi-tier or multi-stack) terminal
block. On the schematic drawing, each schematic terminal symbol represents
one level of the multi-level terminal block.
NOTE Multiple terminal symbols for one level are not currently supported.
The number of levels for the block is defined as a block property. Each level
carries certain characteristics, such as a label, wires per connection, left pin,
and right pin. Each schematic terminal symbol carries all the block properties
for each level so that removing one terminal symbol does not remove the
block properties. If a block property is modified, all the terminal symbols
update.
An ID value held on the LINKTERM attribute or Xdata, associates the terminal
symbols. When a terminal symbol is inserted, by default it is seen as a
standalone terminal (it has no associations) and receives a new LINKTERM
value. When the terminal is associated to another, the LINKTERM value
updates so that each terminal carries the same LINKTERM value. Changing
or removing the LINKTERM value breaks any associations that terminal has.
