the PC to the device during which time the entry menu is dis-
played. No menus can be selected while text is being down-
loaded from the PC to the RE.316*4.
For measuring values the display is refreshed approximately
every second.
5.13.5.4. Configuration
The menu structure described below is largely fixed and nothing
needs to be configured. It is neither possible to add a menu item
nor change a menu text. Certain menu items and texts vary with
system configuration and are therefore indirectly variable. For
example, if an additional protection function is configured, the
menu items needed to view its measurements are automatically
inserted. The signal texts are copied from the HMI on the PC.
5.13.6. Menu structure
The information displayed on the LDU is accessed via a menu
structure with five levels. An overview of the menu structure is
given in the diagram below. The user can only move from one
menu item to another in a vertical direction, i.e. it is impossible to
go directly from one menu item to another on the same level, but
in a different branch.
Every menu item consists of two parts:
· Header (first line on the LCD): The header shows the name of
the active menu. A menu name starts and finishes with a hy-
phen to distinguish it from the menu items available for selec-
tion. The header with the menu name is always displayed
even if there are more than three items in the menu and it is
necessary to scroll through them.
· Menu lines: The menu items available for selection are dis-
played on lines two, three and four. Note: An arrow pointing
downwards at the end of line 4 means that the menu contains
more menu items below the one displayed. These can be
viewed by pressing the arrow key “v”. An arrow pointing up-
wards at the end of line 2 means that the menu contains more
menu items above the one displayed. These can be viewed
by pressing the arrow key “
