number 2 relates to the exiting from the service menu.
Successively, the machine has vend with success product number
11. After this vend, the partial vends counter of the specifi c product
is raised by 1 whilst the product availability counter descends
from the full load of 14 to 13. The absolute counter of takings
has totalized 10 base coins, whilst the absolute vends counter has
totalized 1. Also, during that particular vend the temperature of
the refrigerator was 12.5°C.
It results obvious also the description of the following sale effected
on product number 12.
The vend of a product is defi nitely the most recurrent event in the
machine. However, many other events are registered, such as the
turning on of the machine and all possible verifi able anomalies.
Registration of events is autonomous and automatic and the board
is capable of memorizing more than 1700 events (lines) in its
permanent memory. The mechanism of registration is equivalent
to that of a continuous tape so that, reaching the registration of
the maximum number of events, new records will successively
take the place of the older ones.
To keep track of all events for the entire life of the machine it is necessary to download periodically with a PC the contents of
the memory of the data-logger. The software on the PC will save
the current contents of the register on a text fi le, automatically
assigning a name composed of an arbitrary text added to the
machine number and the time/date of acquisition. In this way,
every acquisition fi le will be unique, as will be the identity number
of each event of the machine. In this way, it is possible to archive
on a PC the data-logger fi les and keep track of each single sale of
each machine installed for the duration of said machine.
PROGRAMMING BY PERSONAL COMPUTER
The CN1 programming connector constitutes a serial portal
RS232 of access to the board (and thus to the machine) with
enormous potential.
This communication portal consents principally to read and
write about 900 working parameters of the machine. In this
way, it is possible to set-up the functioning of the machine
contemporaneously or alternatively to the use of the keypad and
display. Having read the parameters of the machine it is possible
to modify them and re-transfer to same. Also, the parameters
taken can be saved to fi le and vice versa it is possible to recall
from a fi le a certain batch of values of the parameters to then
transfer to the machine. In this way the optimum parameters can
be archived to a PC by fi le (for example using a different name for
each machine) to be re-used to confi gure other machines.
By PC it is also possible to set-up the watch of the machine or
read, save to fi le and visualize the contents of the data-logger. An innovative characteristic of the board is the possibility to
modify and personalize all the graphic images which appear
on the display. In particular, amongst these images, there are 8
Spots which can be used for publicity, warnings and information
of all types. The Spots are full screen graphic images which
require the creation of such fi les as BITMAP monochrome with
resolution 128x64. Programs of image elaboration can be used
