Contatto
ModKB
When the ModKB receives a message from the keyboard,
it verifies that the SITE code is correct, then verifies that
the entered PIN code is one of those stored; if everything
matches, before allowing access, ModKB module also
evaluates the following parameters related to that PIN:
•
the day of the week when the access is allowed
•
the two time slots when the access is allowed
If all the listed conditions have satisfied, then the ModKB
module generates a pulse on the relay in order to activate
the electrical door lock or other similar device.
Moreover, whether those conditions have been satisfied or
not, ModKB will send on the bus some information related
to the recognized PIN as described below.
Information from and to ModKB module
ModKB module takes, inside the
Contatto
system, one in-
put and one (optional) output address with the same value.
The output address, if it is not needed, can be disabled dur-
ing the setting up.
Input section
The input address provides four 16-bit channels, used as
described in the following.
Input channel 1: digital inputs

The
points 1 and 2
report the status of the two generic in-
puts of ModKB module. The logic of the contacts connec-
ted to these inputs depends on the NC/NO configuration
which has been chosen, during the setting up, for each one
of them. If the input has been configured as NC, then the
status on the bus will be 1 when the contact is opened; if
the input has been instead configured as NO, the the status
will be 1 when the contact is closed.
The
points 9
÷
12
will be activated when ModKB module
denies the access for one of the reasons described above.
The information related to these points remains for the time
set in the configuration panel of ModKB (Code Perman-
ence, 5 seconds typical value).
Input channel 2: entered code
This channel shows the last PIN code typed on the keypad;
this code remains in this channel for the set time (Code
Permanence) then it returns to zero.
Input channel 3 and 4: valid PIN codes
These channels report 30 mutually exclusive points, each
one corresponding to the occurred recognition of one of the
30 PIN code set in ModKB. The point related to the last val-
id entered code remains active for the set time (Code Per-
manence), then it returns to zero.

Activating the
point 1
of CH1, ModKB module generates a
pulse on the internal relay, whose duration can be fixed
during the setting up; only one pulse will be generated even
if the output point 1 remains in active status or less.
