Wire connection/terminal pin number pairs
DescriptionAttribute
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. It also provides a link to an associated terminal
number (TERMn) and a terminal description (TERMDESCn) attribute.
The "?" character position is used to identify the preferred wire con-
nection 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 that radiate from a circle.
NOTE When a component is inserted with, nearby wires
try to connect to this type of attribute only if it has a de-
fault prompt value of “X0STRETCH”
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.
NOTE X?TERMn attributes can be stand-alone, meaning there is not
an associated TERMn attribute.
Optional wire connection description attributes that match up with
X?TERMn wire connection attributes (128 characters maximum). The
X?TERMDESCn
value assigned to each termination description attribute can be ex-
tracted into various wire connection reports or merged onto panel
wiring diagram representations of schematic symbols.
Use these attributes to define a terminal as an internal or external
connection.
Optional terminal pin number attribute where "n" is a two-digit
number (starting at 01) that is used to match up with the correspond-
ing X?TERMn wire connection attribute (ten characters maximum).
TERMn
A single TERMn attribute can have two, three, or four wire connection
attributes associated with it. For example, a round, stand-alone ter-
minal symbol having a single terminal in number attribute TERM01
