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.
