5.3. Operation
5.3.1. General
The HMI can be in one of four modes:
· Menu: waiting for the user to select a menu item.
· Operation: waiting for the user to enter data, e.g. parame-
ter settings, confirmation of prompts, password
etc.
· Output: display of measured variables, event lists etc.
These windows are closed by pressing <En-
ter>.
· Wait: while the program executes a command (key-
board disabled). This can occur in any of the
above modes.
A menu presents the user with a list of functions to choose from.
A menu item is selected by moving the selection bar up or down
using the up and down arrow keys and then pressing <Enter>.
As the user moves down the menu structure, the menus overlap
each other on the screen. The whole screen is used to display
data. Auxiliary menus and messages are displayed in pop-up
windows and editing functions uses a combination of windows
and full screen.
5.3.2. Standard key functions applicable to all menus
Except while setting parameters, responding to prompts and
executing special functions, the user is always confronted by a
menu, from which a menu item or line normally has to be se-
lected. The following keys perform the same functions for all
menus:
<> Previous line
<¯> Next line
<PgUp> Scroll up
<PgDn> Scroll down
<Home> Go to the beginning of the menu
<End> Go to the end of the menu
<Enter> Execute the operation described by the line
<Esc> Back to the previous window.
