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.
To associate schematic terminals, first add block properties. The number of
terminals you can associate is limited to the number of levels defined in the
block properties. Once block properties are established you can associate
schematic terminals to build a multi-level terminal block by:
■ Click Schematic tab ➤ Edit Components panel ➤
➤ Associate
Terminals.
You select a master terminal and then select each terminal symbol to
associate to the master.
■ Clicking Pick on the Insert/Edit Terminal Symbol dialog box. It adds the
edited symbol into an association with the picked terminal.
■ Clicking Add/Modify on the Insert/Edit Terminal Symbol dialog box. It
adds the edited symbol into an association with any schematic terminal
in the project.
Prebuilt circuits can contain associated terminals. These relationships are
maintained when the circuit is inserted. Copying a circuit also maintains these
relationships within the copied circuit.
When the Bill of Materials report is run, these separate terminal symbols that
make up one multi-level terminal, are counted as one in the quantity.
Schematic-to-Panel
The schematic-to-panel relationship is used mainly for updating. If the
schematic or panel is modified, the other updates to reflect the changes. This
