Product Description
Ordering Key
G 3496 0004 is designed as a
cost-effective solution for
interfacing Dupline
I/O's to a
Omron PLC. It performs three
functions: Dupline
channel
generator, power supply syn-
chronization (enables 3-wire
system with supply) and
RS232/RS422/RS485 inter-
face.

Mode of Operation
The Dupline
Master Module
(DMM) controls a 3-wire bus
with signal, DC-power and
common GND. The DMM is
connected to a standard DC-
supply, which it synchronizes
with the Dupline
carrier signal
before it is output to supply.
The synchronization is neces-
sary in order to enable the
Dupline
and DC-supply to
share the GND-wire.
The Dupline
Master Module is
a Dupline
Channel Generator
with the function of a master.
This means that the 128
Dupline
I/O's will be read/writ-
ten by the DMM and then sent
to the PLC.
The DMM can run in two dif-
ferent modes Normal mode
and split I/O mode. In Normal
mode, Dupline
operates as a
peer-to-peer system, where
the channel generator auto-
matically establishes a con-
nection between Dupline
inputs and Dupline
outputs
which are coded to the same
Dupline
address. If e.g. an
input coded for B5 is activat-
ed, the output(s) coded for B5
will also be activated.
Consequently, a Dupline
-out-
put can either be activated
through the output-data
received on DMM or by an
active Dupline
input coded
for the same Dupline
-
address. In "Split I/O" mode,
the channel generator treats
the Dupline
inputs and
Dupline
outputs indepen-
dently. If e.g. an input coded
for B5 is activated, the DMM
will make the information avail-
able for the PLC (like in normal
mode), but it will not automati-
cally activate the Dupline
out-
put(s) coded to B5. The
Dupline
outputs are con-
trolled exclusively through the
output data received from the
PLC. In this mode, up to 128
Dupline
inputs and 128
Dupline
outputs are available,
since an input and an output
coded to the same Dupline
address can operate indepen-
dently.
