OPERATOR'S TERMINAL
Fig. 1. Excel 50 Man-Machine Interface
The Excel 50 controller's MMI (Man-Machine Interface, see Fig. 1) consists of a
keyboard and a display described below.
Keyboard
The keyboard has 8 basic function keys and 4 fast-access keys described below.

EXCEL 50 MMI - USER GUIDE
EN2B-0222GE51 R0216 2
Basic Function Keys
The effects of pressing the basic function keys are summarized below.
CANCEL: Enables you to escape to the root screen, to cancel an
incorrect entry, or to confirm an alarm message.
UP ARROW: Moves the cursor to the previous field of a screen or, when
already at the top of a screen, to the bottom field.
DOWN ARROW: Moves the cursor to the subsequent field of a screen
or, when already at the bottom of a screen, to the top field.
RIGHT ARROW: Moves the cursor to the next digit to the right of a field,
to the subsequent field, or to the first field of a subsequent screen
(equivalent to "page down").
LEFT ARROW: Moves the cursor to the next digit to the left of a field, to
the previous field, or to the last field of a previous screen (equivalent to
"page up").
PLUS: Increases the displayed numerical value by 1. In the case of a
digital state, it changes the state to the opposite state. Increments scroll
bar values (i.e. destination screens). Creates new "Daily" or "Annual"
schedules.
MINUS: Decreases the displayed numerical value by 1. In the case of a
digital state, it changes the state to the opposite state. Decrements scroll
bar values (i.e. destination screens). Deletes existent "Daily" or "Annual"
schedules.
ENTER: Confirms any changes made or shifts to the subsequent screen.
See also section "Resetting" on page 3.
The effects of pressing the basic function keys differs depending upon whether
the current screen contains only display fields, edit fields in the edit mode, edit
fields in the display mode, a scrollbar, etc. It also depends upon the procedure
you are currently carrying out (e.g. time schedules). See also Table 1 on page 3.

Resetting
NOTE: A reset has a more-severe impact than simply switching off the device:
All RAM data and all configuration codes are lost, and the controller will
therefore have to be re-initialized (see "Powering Up / Resetting the
Controller" on page 47) in order to work with it. You should reset your
Excel 50 MMI only as a preliminary to downloading a new
application.
& Simultaneously pressing the DOWN ARROW key and the MINUS key
causes a reset.
A reset can also be achieved by pressing the hardware RESET button at the rear
of the controller housing under Terminal Block B.

Fast-Access Keys
The use of the fast-access keys is summarized below.
PLANTS: Displays a list of the selected plant components and their
current states.
TIME PROGRAMS: Displays a list of configured time programs and
provides all time schedule customization options.
SYSTEM TOPICS: Available only in access level 3. Provides system
settings and application parameters.
ALARMS: Displays alarm information on alarm history, points currently in
an alarm condition, critical alarms, and non-critical alarms.
LCD Display
The LCD display can present four lines of alphanumeric text, with 16 characters
per line, and has been provided with back-lighting to improve legibility.
Screen usually contain one or more edit fields and display fields interspersed
among its four lines. The current edit field is indicated by the presence of a
cursor (arrowhead) to the left of it. In the case of edit fields consisting of several
digits, the current digit will be flashing. See Fig. 2.
Fig. 2. Typical screen with cursor and edit fields
NOTE: The screens shown in this User Guide are examples (taken from
application HE01) and may differ slightly from the screens visible on your
Excel 50 MMI.

INITIALIZATION AND ENTRY
Fig. 3. Initialization and entry sequences
Initialization Sequence
Upon downloading an application into your Excel 50 MMI (see also "Powering Up
/ Resetting the Controller" on page 47), the initialization sequence will begin. This
initialization sequence consists of a series of four screens (see Fig. 3). If the
configuration codes are correct, the initialization sequence should be immediately
followed by the entry sequence (see section "Entry Sequence" on page 5).
Entry Sequence
After the application has been downloaded, the entry sequence will begin. The
first screen is the start screen (see Fig. 4).
Fig. 4. The start screen
The start screen includes the name of the application (in this case, HE01) as well
as the current date and time.
If "BW-MMI" appears, this means that the controller offers C-bus access (which
you would need to communicate with modules located on a C-bus). See section
"C-Bus Configuration" on page 35 for more information.

EXCEL 50 MMI - USER GUIDE
EN2B-0222GE51 R0216 6
NOTE: The two-digit CPU field (in the upper right-hand corner), the date, and
the time will be editable only if you are already in access level 3 (see
section "Access Levels" on page 6).
NOTE: The "Logout" edit field will appear only if you are already in access level
2 or 3 (see section "Access Levels" on page 6).
Selecting the "Password" field will take you to the password procedure (see
section "Password Procedure" on page 6).
Access Levels
The use of three access levels ensures that only authorized personnel can
read/edit sensitive system data. In order to enter access level 1, no password is
necessary, and only those screens accessible at that level will be displayed (see
also Table 2). In order to enter access levels 2 and 3, a corresponding password
must be entered.

scroll downwards through several screens in order to display all of the items.

EXCEL 50 MMI - USER GUIDE
EN2B-0222GE51 R0216 10
NOTE: In the case of listboxes spread out over three or more screens, use of
the scrollbar (the value of which is incremented or decremented with the
PLUS and MINUS keys; see also Table 1 on page 3) can greatly simplify
navigation by allowing the user to skip ahead to the screen of interest.
Data-Point Attributes
Selecting an individual data-point (e.g. OATmp) will cause a series of screens
(viewable in its entirety by scrolling sideways) with a corresponding heading to
appear (see Fig. 10).
Fig. 10. Data-point attributes (first screen of a series)
Depending upon the type and sub-type of the given data-point (see section
"Types of Data-Points" on page 25) this series will consist of a varying number of
screens containing edit fields in which you can specify the data-point's various
different attributes. You will thus have to scroll sideways through several screens
in order to display/configure all of the fields.
NOTE: See "Appendix 1: Data-Point Attributes" on page 56 for an explanation of
the meaning of the expression "data-point attributes", an exhaustive list
of all the possible attributes, their meanings, and how to edit them.
