Domino
DFCK
III
Operation
DFCK
III
module has been developed to be used in associ-
ation with a terminal (touch screen or other device) used as
graphical interface of the clock module, thus allowing to
show and set the date and time and to edit the scheduled
times.
DFCK
III
module, from the
Domino
bus point of view, is ful-
ly equivalent to a digital input module; each point of the
module corresponds to a zone and must be identified with
the usual notation
Ix.y
, where y is in the range 1 to 15.
Each point will be activated as function of the scheduled
times (see the programming paragraph) and must be used
in proper equations to execute the desired command on
the outputs. The points of DFCK
III
can be used as a usual
input points of the system.
The operation of the module is very simple: the points relat-
ed to the controlled zones will be activated according to the
programmed scheduled times.
As said above, it is possible to install more DFCK
III
mod-
ules on the same bus line. Only the MASTER module will
send on the bus the date (1 time per minute) and the hour
(6 times per minute), in order to keep synchronized the oth-
er modules and to allow the use of the CLOCK equation.
A change of the time on any DFCK
III
module (regardless
of the MASTER or SLAVE setting) will be automatically re-
ported on all other modules.
If DFCP is installed on the bus, its CLOCK will be the MAS-
TER in respect of the other DFCK
III
modules, therefore all
the DFCK
III
modules must be set as SLAVE (thus with ID
in the range 2 to 8).
Clock
The DFCK
III
module has an internal clock with back-up
battery that operates in the case of absence of supply to
maintain the setting of date and time. The change between
Greenwich mean time an the daylight saving time and vice
versa is automatically managed by the module.
Programming
DFCK
III
module behaves, in the
Domino
bus, as an input
module, thus the 15 different possible zones will corre-
spond to 15 inputs. In other words, these inputs will be
seen as real input points to which it is possible to apply all
the allowed programming functions. For example, to acti-
vate 4 outputs at the activation of 4 different zones of
DFCK
III
(in this example the first 4 zones), the equation to
be loaded in the output module will be:
O1.1
=
I1.1
O1.2
=
I1.2
O1.3
=
I1.3
O1.4
=
I1.4
In this example, a DFCK
III
module with input address 1
and an output module with address 1 have been used.
Setting up
To make operating the module, it is necessary to set the
several parameters through the configuration panel in the
program
BDTools version 8.3.0 or higher
. From the main
menu of BDTools, select “Configuration”, “Clocks” and then
“DFCK
III
”; the following window will appear.
On the top side of the window, the teo following parameters
have to be entered:
Module Address
: to unambiguous identify of selected
DFCK
III
ID
: to identify if the module will be MASTER (ID equal
to 1) or SLAVE (ID from 2 to 8). The ID is not the ad-
dress; every DFCK
III
in the same bus system will
have different ID.
The configuration panel is divided in 15 TABs; each TAB
has to be filled with the following information:
Description
: is the name assigned to the currently se-
lected zone
Read
: to read the configuration of the selected zone of
DFCK
III
selected by the address field (regardless of
the ID). With the option “All 15”, all 15 zones will be
read
Program
: to program the configuration of the selected
zone of DFCK
III
selected by the address field (regard-
less of the ID). With the option “All 15”, all 15 zones
will be programmed
