5.2 Behavior of the Operating Device During Start-Up
5.2.1 With Valid Project
When you apply the supply voltage, all LEDs on the operating device
are activated. A system test is then carried out, to check and initialize
the modules in the operating device.
The system test may issue different system and error messages. If the
device contains a valid project, the start-up mask or the mask entered
as the start-up mask in the language parameter is displayed. This
mask is displayed five seconds. This time is set as a fixed value. You
can use this time to check whether the LEDs and the display are func-
tioning correctly.
Once this time has expired, the main mask, or the mask set as the
main mask in the language parameters, is displayed. This mask is also
the first mask of user interface.
If the main mask contains a controller variable, and communication
with the controller fails, an error message is displayed (instead of the
main mask), which provides details about the communication error that
occurred.
If you press the Enter key or similar button while the start-up mask is
being displayed, the setup mask or the mask set in the language
parameters is displayed. In this mask, for example, parameters are
assigned to the interfaces. If you press any key before the start-up
mask appears, an error message is generated when the keyboard is
being checked. The error message includes the data for clock fre-
quency, memory size, firmware level, protocol driver, programming
software version, and the project name.
The display of the setup mask may be delayed if the message memory
contains several messages of the serial message system. This is
because time may be required to set up message management struc-
tures. However, this initialization time considerably reduces the time
subsequently required to sort messages. A corresponding message is
displayed during this time period.
5.2.2 Without a Valid Project
If no valid project exists, the Flash memory is erased, and the operat-
ing device automatically switches to the download operating mode.
The message 'DOWNLOAD 1' remains on the screen. This message
indicates that the operating device is now ready to receive a valid
project via the download interface. If no valid project is available in the
memory, there is no communication with a connected controller, and
the keyboard will not execute any functions.
