KEP MMI-1500 Installation & Operation Manual page 42

No. of windows: This setting is used to specify the maximum number of windows allowed open at
any one time (1 - 6). The unit ignores attempts to open more windows than specified until an
existing window is closed.
When more windows are open than recommended, system resources may drop low enough to
trigger a "System severe error" message". When the error occurs, the unit must be reset or power
must be cycled to the unit before project execution can resume.
Note: The maximum number allowed is 6. It is recommended to reduce the maximum by one for each of the following
conditions:
• The project has a Common window.
• The project has a Message board window.
• The project has print screen functions.
• The project is using bitmap compression.
If all of the above conditions apply, restrict the maximum number of windows allowed to 2.
Note: The size of the minimized icon on the Task Bar is decreased as the minimum number of windows is increased. By
selecting a lower number, more room is given for a descriptive title in the minimized icon.
Startup window No.: This is the window displayed when the HMI is powered up. Valid window numbers are 10 - 1999.
Note: If the specified window does not exist, the unit displays "System severe error (error code 10101)" when started.
Cursor color: Determines the color of the cursor when displayed. The full range of colors is available for this parameter.
This is used with Data Input Extend and ASCII Input Extend parts. The cursor (a flashing block) indicates when data entry is
enabled for a selected value.
Password: Activate the password option by entering any number greater than 0. This locks the project after it is downloaded
so it cannot be uploaded without first entering the password.
Note: Password protection does not prevent the user
from Downloading. There is no protection to prevent
a project from being overwritten.
Back light saver: The HMI turns off back light power if there are no touch operations within the set
time (Range: 0 to 255, unit in minutes). A zero setting disables the back light "auto shutoff" function.
Buzzer: The buzzer sounds briefly every time the touchscreen is activated by touch. This selection
allows the programmer to turn off the buzzer. The buzzer can be annoying in some applications and
during development phases of a project.
Note: The buzzer cannot be assigned to alarms and is not associated with alarm functions.
Note: There are no provisions for the user to control the buzzer.
