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.

Existence Explanation
Obligatory (green icon) A system program running in the
CDU.
Unknown (yellow icon) An unlicensed application. Close the

more licenses if necessary.
Missing (red icon) The object is missing. You may need
to reboot the system.
The object status icon is in the leftmost column. This icon shows the
status of the ROA object. The icon can be green, red, or yellow. The
green icon indicates normal status.
