Each system resource has settings that can be viewed or changed from
the command line. These settings are called attributes. Each attribute
can be referenced by an identifier. For example, the object DC1 has a
DC voltage attribute identified as VDC and a DC current identified as
ADC. References to attributes are always made with respect to its
object. For example, the command to view the plant current is
STA DC1,ADC
In this command, STA is the view status command header, DC1 refers
to the DC plant 1 object, and ADC refers to the DC current attribute.
Objects can be linked together to create a hierarchy of objects. For
example, because rectifiers are part of the DC plant, rectifiers G01 to
G64 are linked to DC1. In this example DC1 is the parent object of the
rectifiers and the rectifiers are the children of DC1. Objects are linked
together by a special attribute of the parent called a linkable attribute. In
our example, rectifiers are linked to DC1 via the REC attribute. The
REC attribute of DC1 happens to have the same name as the rectifier
type identifier. As another example, the rectifier fail alarm, RFA1, is
linked to DC1 via the RFA attributes. The result of this link is that a
rectifier fail alarm will be reported as a DC plant alarm.
The objects supported by this system are described in detail along with
their attributes in the appendix. Most objects are a permanent part of the
system; they cannot be added nor deleted. Some objects, such as remote
peripheral monitor objects, are added to the system automatically based
on the hardware configuration. Other objects may be added on as
needed. These objects include user-defined objects, user-defined events,
and TL1 objects.
Users can customize the system by creating their own parent to child
relationships using user-defined objects, user-defined events, and
remote peripheral monitor objects. This is done by using commands to
add an attribute to a parent object, add a child object to the system if
necessary, and then link the child to the parent at the newly created
attribute. The command descriptions below describe how this may be
done.
Commands The command set is divided into two groups, operation commands and
report commands. In this section each command is described along with
its syntax and report format.
