ModKB
ModKB: Module for PIN code access control
ModKB module has been specially developed for the con-
nection to third-party numerical keypads using WIEGA D
standard protocol.
ModKB module interfaces, through MCP XT controller, to
the well tested Contatto world, thus integrating it with an
easy to use PI code based access control system. The
main features are the following:
•2 generic Contatto inputs
•1 relay output for electrical door lock control
•2 LED outputs for OK and OK codes
•WIEGA D 32 or 26 protocol (SITE code and PI )
•programmable pulse duration on door lock relay
•“SITE code” management for keypad identification
•PI code management
•up to 30 different PI codes can be defined and stored
•for each PI it is possible to define the days of the
week during which the access is granted
•for each PI it is possible to define up to 2 time slots
during which the access is granted (provided that the
access occurs during one of the allowed days)
•the module takes 1 input address reporting on the bus
the entered PI code, the status of the generic inputs
and other information for diagnostic
•the module takes 1 optional output address allowing to
separately lock each one of the 30 PI codes and to
drive the relay
ModKB module features a 12-way removable terminal
block for the connection to the keypad (not provided), to the
generic inputs and to the LEDs reporting the granted or
denied access information. The normally opened contact of
the internal relay of ModKB is available on a separated 2-
way removable terminal block, allowing the connection to
the electrical door lock or similar devices.
An additional 5-way removable terminal block allows the
connection to the Contatto bus.
ModKB module housing is a reduced-height 3 modules box
for DI rail mounting.
Operation
ModKB module allows the access control through the en-
tering by the user, on a keypad, of one of the 30 codes pre-
viously stored in the module.
ModKB is compatible with keypads having serial WIE-
GA D protocol; the data transmitted by the keypad is
made by the SITE code (identifying the keypad) and the
PI code. The SITE code is a 16-bit number for WIEGA D
32 and it is a 8-bit number for WIEGA D 26; in both cases
the PI code is a 16-bit number.
The SITE code must be set in the keypad during the setting
up of the plant using the procedure defined by the manu-
facturer of the keypad.
Since the PI code is a 16-bit number, then it will be in the
range 00001 e 65535.
The module can be set to recognize up to 30 different PI
codes, for instance each one related to different categories
of personnel; if the entered code corresponds to one of the
stored 30 ones, ModKB will check if the access has been
required in a allowed day and in an allowed time slot. The
time slots that can be set for each PI code are two and,
once set, they are valid for each allowed day of the week.
All evaluations for deciding if the entered PI code is valid
will be fully executed by ModKB module; the control of the
electrical door lock (or similar devices) will be also automat-
ically performed by the module itself.
In this way, the Contatto MCP XT controller does not need
any specific programming, thus drastically reducing the
times needed for the development and the setting up of the
access control system. In this way, therefore, the operation
of the access control system is guaranteed also in case of
temporary failure of the bus.
It is however possible to set ModKB module in order to it
does not take autonomous decisions, thus leaving the
management of the access to MCP XT controller or to the
supervisor of the system; in this case ModKB module will
be limited to transmit on the bus the entered OI code.
Address programming
ModKB module takes one 4-channel / 16-bit input address ;
as option, one 1-channel / 16-bit output address can be ac-
tivated in order to executed some commands as will be de-
scribed in the following.
The input and output addresses are equal each one to the
other, so only a base address is needed; this one must be
assigned by FXPRO programmer.
Digital inputs
ModKB module features 2 Contatto generic digital inputs,
which can be therefore used for the connection to potential-
free contacts supplied by the module itself.
These two inputs can be separately configured both for O
and C logic during the setting up.

Installation
The wiring diagram in Figure 1 shows the connection to be
executed between ModKB module and the bus, the
keypad, the electrical door lock, the input contacts and the
optional LEDs. For details about the connection of the third
party keypad refer to the manufacturer technical sheet.
ModKB module features a green LED near to the bus ter-
minal lock, lighted when the module is properly supplied.
The contacts connected to the inputs in Figure 1 are O
type only to give an example, being possible to configure
each input according to the desired O/ C logic (see in the
following pages of this manual).
The following table gives some hints about the section of
the wires to be used for the connections and the suggested
maximum length.
Connection Suggested wire
Bus 4 x 2.5 mmq not shielded
Inputs 0.5 mmq, MAX 25mt
LEDs 0.22 mmq, MAX 25mt
Door lock 0.5 mmq
Keypad 5 x 0.5mmq, MAX 15mt
Method for the access control
The access control is based on the entering of a PI code
through the keypad.
The check of the entered PI code, executed by ModKB
module, is performed according to the rules described in
the following.
The PI codes to be enabled (up to 30) can be freely
defined during the setting up and transferred to the memory
of ModKB through the Contatto bus.
The first 8 or 16 bits (depending WIEGA D 26 or 32 re-
spectively has been chosen) transmitted by the keypad cor-
responds to the SITE code set on the keypad itself; this
code uniquely identifies the keypad connected to a given
ModKB module. The next transmitted 16 bits corresponds
to the entered PI code, thus making a number in the
range 00001 to 65535.
ModKB module features a non-volatile memory containing
30 blocks of information, each one related to a different
PI code that must be granted; the same SITE code set in
the keypad must be stored in the ModKB memory too.

ModKB
When the ModKB receives a message from the keyboard,
it verifies that the SITE code is correct, then verifies that
the entered PI code is one of those stored; if everything
matches, before allowing access, ModKB module also
evaluates the following parameters related to that PI :
•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 PI 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 C/ O configuration
which has been chosen, during the setting up, for each one
of them. If the input has been configured as C, then the
status on the bus will be 1 when the contact is opened; if
the input has been instead configured as O, 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 PI 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 PI 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.

Output section
On the output address, if it has been enabled during the
ModKB setting up, four 16-bit channels are available; the
following tables shows the arrangement:

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.

The channel 2 is not used. Channel 3 and 4 report 30 digit-
al points which, when activated, deny the access to the re-
lated PI code. The point 15 of CH4, when activated,
denies the access to any PI codes.
Configuration of ModKB module
This paragraph describes the configuration of ModKB mod-
ule, allowing to adapt its operation according to the re-
quests of the specific application, and to enter the PI
codes s that must allow the access.
For the configuration of ModKB module, MCP IDE program
for MCP XT has to be used. The configuration of the mod-
ule is performed through the Contatto bus.
Note: ModKB module can work only if the MCP XT controller has
been installed the configuration and the programming of MCP XT
requires the software package MCP IDE.
All ModKB modules installed in the plant must be declared
in the MCP XT configuration, specifying the addresses as
in the following example (where the output address has
been supposed enabled):
MODKB = ( I100, O100 )
MODKB = ( I101, O101 )
MODKB = ( I102, O102 )
… … … …
After having transferred a program to MCP XT containing
at least the addresses of installed ModKB modules, the
second step is the setting of the operating parameters.
From the menu of MCP IDE select Programming, Modules
Configuration and then ModKB.
The window shown in Figure 2 will appear, where:
Module Address: this is the address of ModKB module to
be configured.
Enable Output Address: this option enables the output
address, thus allowing the execution of commands to the
ModKB as described in the paragraph “Output section”.
Pulse Length (msec): it is the duration of the pulse gener-
ated on the internal relay of ModKB for driving the electrical
door lock or similar devices. This duration can be defined at
100msec steps; the maximum allowed value is 25500, that
means 25.5 seconds.
Code Permanence: it is the time, in seconds, during which
the information remain in the input section; the maximum
allowed value is 255 seconds.
SITE code: it is the code set in the keypad and it is a num-
ber in the range 0 to 255 for WIEGA D 26 keypad, or 0 to
65535 for WIEGA D 32 keypad (for the procedure to set
this code refer to the documentation of the keypad).
N.C. Inputs: allows to choose the logic for each on e of the
two available inputs. If an input has been configured as C,
then the status on the bus will be 1 when the contact is
opened; if the input has been instead configured as O,
the the status will be 1 when the contact is closed.
The table in the bottom side of the configuration window
shown in Figure 2 allows to define the PI codes and other
related parameters.
