The unit can be easily identified by the Unit Name when browsing remotely. The
name can be changed by double clicking on it.
The color of the Alarm Status Bar indicates the highest actual alarm severity. The
bar is red in case of an alarm with critical severity, orange if an alarm or warning
with any severity other than critical and no alarm with critical severity is issued, and
green otherwise.
5.1.1.2 Navigation Area
The unit is controlled through five different web pages, each of them responsible for
a well-defined control task. The pages can be accessed through the top menu in the
Navigation area. Where appropriate, control tasks are further broken down into
smaller subtasks. Each subtask has its own tab.
Figure 5.3 Navigation Area
The area below the tabs serves as a taskbar with two buttons on it. The Apply All
button allows the user to commit the changes made to any of the parameters on the
displayed page or tab. With the Discard All button the changes can be revoked and
the state prior to the modifications can be recalled. Modified parameters are
highlighted in orange. If the user first modifies some parameters and then tries to
navigate away from the page or tab, a warning dialog is displayed. The buttons do
not appear on every page.
The information next to the buttons displays the number of running tasks and the
processing status of them.
5.1.1.3 Widgets
Widgets are containers that allow the user to perform specific actions or display
relevant information. Widget can be resized by dragging the splitters between them.
By double clicking on the splitters the widgets can be collapsed to provide more
room for neighboring widgets. Double clicking on a splitter again redisplays the
previously hidden element.
