ABOUT THIS USER GUIDE

This User Guide describes operation of the Excel 50 MMI for configurable applications with Version 2.05 (or higher) firmware. It focuses on changes in operation with respect to Version 2.04.

Version 2.05 introduces a number of significant software improvements facilitating operation of the MMI. These improvements are essentially as follows:

• The number of keystrokes necessary to access important information and/or to

reconfigure applications has been considerably reduced.

• Moving from screen to screen has been simplified.

• The utilization of space in the display screen has been optimized.

Additionally, one important hardware improvement should also be mentioned:

• The display screen has been equipped with back-lighting to enhance

readability.

OPERATOR'S TERMINAL

Fig. 1. Excel 50 Man-Machine Interface

EXCEL 50 USER GUIDE

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.

1 EN2B-0222GE51 R1101

ALARM DESCRIPTION EXCEL 50 USER GUIDE

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 48) 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.

ALARM DESCRIPTION EXCEL 50 USER GUIDE

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 48), 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 36 for more information.

ALARM DESCRIPTION EXCEL 50 USER GUIDE

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.
