Product Description
Ordering Key
G 3496 0000 is designed as
a cost-effective solution for
interfacing Dupline
I/O's to
control systems. It performs
three functions: Dupline
channel generator, power
supply synchronization (en-
ables 3-wire system with
supply) and RS232/RS422/

Mode of Operation
The Dupline
Master Module
is a Dupline
Channel
Generator with the function of
a slave. This means that the
128 Dupline
I/O's can be
read/controlled by a PC/PLC
or a Control board master from
many different suppliers. Up to
16 Dupline
Master Modules
can be connected to the same
network and operate together
with other modules using the
same protocol like operator
panels, MMI's frequency
inverters, I/O-modules etc.
When the Dupline
Master
Module has received a
telegram with output data for
Dupline
Receivers, it will
automatically respond with a
telegram with input data from
Dupline
Transmitters.

All telegrams are built up as
shown in schedule - no matter
if they are sent from the
PC/PLC/ Controlboard to the
DMM or they are returned by
the DMM.
The communication is execut-
ed by using telegrams that
start with the ASCII-character
"s" and end with the ASCII-
character "e". All information
transmitted between these
two characters is compressed
to achieve short telegrams
with a high data throughput.
By using this compression, the
signal status of the 8 channels
within a Dupline
address
group are transmitted as only
two ASCII-characters. This is
done by converting the lower
4-Bit and the upper 4-Bit of a
Data byte into hexadecimal
numbers and the subsequent
transformation of these num-
bers into ASCII-characters.
