Number
Identifies this device connection point’s
position in the group (i.e. 1 st , 2 nd )
Set if describing a device in a bay or if
device connection point is a bay.
Set if the device is ejectable. Indicates
ejectability in the absence of _EJx objects.
OSPM Ejection required: Set if OSPM
needs to be involved with ejection
process. User-operated physical
hardware ejection is not possible.
For single cabinet system, this field is
always 0.

Order
if Set, this _PLD defines a “reference”
shape that is used to help orient the user
with respect to the other shapes when
rendering _PLDs.
Rotates the Shape clockwise in 45 degree
steps around its origin where:
0 – 0°
1 – 45°
2 – 90°
3 – 135°
4 – 180°
5 – 225°
6 – 270°
7 – 315°
Identifies the drawing order of the
connection point described by a _PLD.
Order = 0 connection points are drawn
before Order = 1 connection points. Order
= 1 before Order = 2, and so on. Order =
31 connection points are drawn last.
Order should always start at 0 and be
consecutively assigned.
