Product Description
Ordering Key
G 2196 00.. is a combined
module on open printed circuit
board. The unit performs three
functions: Dupline
channel ge-
nerator, power supply synchro-
nization (enables 3-wire system
with supply) and RS 485 inter-
face. It has been designed as
a cost-effective solution for
multiplexing the push-button
and lamp signals in elevators.
The standard version of the
Master Module has a general-
purpose RS 485-protocol
available, but to facilitate the
interfacing easy, special pro-
tocol versions of the master
module for automatic commu-
nication with specific PLC's/
Controllers are developed con-
tinouosly. These are listed
under "Type Selection".

Mode of Operation
The G 219600.. Dupline
mas-
ter module (DMM) is part of the
Dupline
concept for multi-
plexing the push-button and
lamp signals in elevators. As
shown on the wiring diagram a
3-wire bus with signal, DC-
power and common GND
goes throughout the shaft to all
the push-button panels and
floor indicators, and to the car.
The DMM is connected to a
standard DC-supply which it
synchronizes with the Dupline
carrier signal before it is output
to supply the push-button
panels. The synchronization is
necessary in order to enable
the Dupline
and DC-supply to
share the GND-wire.
The most cost-effective way to
interface the elevator controller
to the master module is to
make use of the RS 485 port
(see wiring diagram). In this
way, the size and the number
of controller I/O-board(s) can
be reduced significantly, since
the I/O-terminals for lamps,
pushbuttons and floor-indica-
tors are no longer needed.
Based on requests from cus-
tomers, special versions of the
master module for automatic
communication with specific
PLC's/Controllers are devel-
oped continuously. This makes
the interfacing very easy, since
these devices automatically
transfer the Dupline
data to/
from the internal memory of
the PLC/ Controller. The ver-
sions available for the moment
are listed under "Type Selec-
tion". More detailed information
about interfacing to the indi-
vidual PLC-types are available.
The standard version G 2196
0000 700 utilizes a general pur-
pose protocol for implementa-
tion in any PLC/Controller soft-
ware. In this case, the commu-
nication is not automatic, since
it must be driven from the
application software.
Another way to implement the
elevator controller interface is
to make hardwired connec-
tions between the I/O's of the
controller and Dupline
-mo-
dules positioned next to it, thus
making use of the peer-to-peer
communication capability of
Dupline
. This solution is less
cost-effective, but highly flexi-
ble since existing and different
control-systems can be used.
