The columns in Figure 43 on page 86 are explained below:
Name
= The Name column shows the ROA object name. By
double-clicking the name (of objects having
Access
type
Application
), you can open a data item window for this
object and view data items belonging to it.
Existence = In the
Existence
column, the system shows the status of
the ROA object in question. In single-CDU systems, the
normal status is
Obligatory
.
In error situations, the status can be either
Missing
or
Unknown
. A
Missing
status is also shown by the red
object status icon.
When the existence of a ROA object is
Missing
, the
system sends an Internal message
Object information
conflict
to Event Monitor. A
Missing
object status
means that the object is not running properly in the
system or, in rare situations, that the object is missing
from the system altogether.
If the existence of a ROA object is
Unknown
(yellow), it
usually means that there is an application running for
which you do not have a proper license. See also Table
32 below.
Access
= Objects are divided into two groups by their access type:
Application
and
System
. If an object has the access type
Application
, you can open a data item window for that
object by double-clicking its name. Objects with the
access type
System
are internal system objects, and you
cannot open a data item window for them; they are only
intended for system internal use.
Types
= The
Types
column contains programming information
intended for Vaisala internal use.
