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.
