HMI
Now that you have configured your communications options, and created data tags for the
various items that you wish to display, you can create display pages to allow the user to view
or edit these data items. These pages are manipulated by selecting the User Interface icon
from the main screen.

ONTROLLING THE

IEW
By default, the User Interface window attempts to show the entire front panel of the Fieldbus
Gateway’s virtual HMI, including the display and all the available fixed keys. In many cases,
this will not allocate enough screen space for the display to be edited, so you will probably
want to use one of the other zoom levels as shown below…
As you can see, at each level, fewer keys are shown, and more of the window is allocated to
the display itself. The view level can be controlled from the View > Panel menu, or by using
the panel icon
, or by pressing the Alt key together with the digits 1 through 4 .

In addition to the panel views, a zoom is available to help graphic designs. Zooming in and
out can be achieved from the View > Zoom menu, or by using the magnifying glass icon
,
or by rolling your mouse wheel up or down.
The Zoom will center on the mouse cursor so you can control which area of the screen you
are zooming to. There are four levels of zoom. The highest level would give the following
screen for the above database.
Due to screen resolution and virtual HMI size, it might not be possible to visualize the entire
screen design even when zoomed out. It is possible however to get this view using the View >
Panel > Show All Screen menu. This menu is only available when the view is NOT in display
