G 3495 0011 is designed as a
cost-effective solution for
interfacing Dupline I/O's to a
Toshiba PLC. It performs
three functions: Dupline
channel generator, power
supply synchronization
(enables 3-wire system with
supply) and RS232/RS422/
RS485 interface.

Pin Assignment
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 outputted to sup-
ply. The synchronization is
necessary 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/0'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
independently. If e.g. an input
coded for B5 is activated, the
DMM will make the informa-
tion available for the PLC (like
in normal mode), but it will not
automatically activate the
Dupline output(s) coded to
B5. The Dupline outputs are
controlled 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.
