Storing diagnosis data
During normal operation, machine internal communica-
tion is permanently logged and deleted after a certain
time. Those log data can be accessed for diagnostic
purpose in error case (comparable to the black box in
an airplane).
To do so, a „snapshot“ of the diagnostic data is stored
in Flash memory, the so-called diagnose dump. Simul-
taneously, the diagnose dump is sent to the debug in-
terface (normally com1).
Storing a diagnose dump is done either
automatically ,
if the machine got in an undefined state, or manually by
pressing all four operation panel buttons simultaneous-
ly:
+ + +
Events, which trigger an automatic storing of the diag-
nose dump:
– Dispensing suddenly stops.
– Status message „unmanaged interrupt“ appears on
the display.
– The device suddenly doesn´t react on keystrokes
any more.
A diagnose dump can be accessed on the following
ways:
– Reading out via serial interface.
– Storing on CF-card as logfile.
In the Flash memory, a certain area is reserved
for diagnose dumps, which provides enough
space for 3-4 dumps. If this area is already
filled, the oldest stored dump is overwritten by
a new one.
