General Specifications
Mode of Operation
The Dupline
PROFIBUS-DP
Gateway is a Dupline channel
generator with the function of
a PROFIBUS-DP slave
according to EN 50 170. This
means that the 128 Dupline
I/O's (incl. AnaLink) can be
read/ controlled by
PROFIBUS-DP masters like
PLC's and PC interface-cards
from many different suppliers.
Several Dupline
gateways
can be connected to the
same PROFIBUS-DP network
and operate together with
other PROFIBUS-DP
modules like operatorpanels,
MMI's, frequency inverters,
I/O-modules etc.
The Dupline
PROFIBUS-DP
Gateway is approved by the
PNO (Profibus Nutzer
Organisation) that ensures
compatibility with other PNO-
certified products.
Configuration Switches
The unit is equipped with the
following configuration
switches (see also Switch
settings):
1 x 16-position rotary-switch
for selecting the Number of
Dupline
channels in the
range 8..128 (in steps of 8).
The selected letter indicates
the last channel group
available on Dupline
. If e.g. H
is selected, the 64 channels in
groups A..H will be available.
2 x 10-position rotary switch
for selection of the
PROFIBUS-DP Slave
Address in the range 02..99.
(00..01 are reserved). Each
module connected to
PROFIBUS-DP must have a
unique slave address which
enables the PROFIBUS-DP
Master to access the modules
individually.
1 x DIP-switch for selection of
Dupline
Operation Mode. In
"Normal" mode, Dupline
operates as a peer-to-peer
system where the channel
generator automatically
establishes a connection
between Dupline
-inputs and
Dupline
-outputs which are
coded to the same Dupline
-
address. If e.g. an input coded
for B5 is activated, the out-
put(s) coded for B5 will also
be activated.
Consequently, a Dupline
-out-
put can either be activated
through the output-data receiv-
ed on PROFIBUS-DP or by an
active Dupline
input coded for
the same Dupline
-address.
In "Split I/O"
mode, the

Dupline
is a registered trademark. A product of the CARLO GAVAZZI Group
G 3891 0021
Dupline-inputs and Dupline
-
outputs are treated indepen-
dently by the channel gener-
ator. If e.g. an input coded for
B5 is activated, the Gateway
will make the information
available on PROFIBUS-DP
(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 on PROFIBUS-DP.
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
independently.
1 x DIP-switch for selection
of Analog Protocol to either
AnaLink (8-bit format) or
multiplex (16-bit format). The
Gateway will only transfer
analog values from modules
using the selected protocol. If
multiplex is selected, the
Gateway will automatically
perform the required
multiplexing on channels A1-
A4. Because of this, these 4
channels are not available as
outputs when the multiplex
protocol is selected.
1 x DIP-switch for version
selection
Normally, the version selec-
tion is supposed to be in the
OFF position, especially when
the Gateway is used in new
installations and configured
with the G38_21.GSD file.
In replacements or expansion
of existing installations, this
switch may be switched on,
in order to make set the
Gateway to operate towards
the previous GSD version.
(Mod-6590.GSD)
Dupline
Input Data
To ease up, the Profibus
Master configuration, the
G38_021.gsd file is to be
used. This file describes to
the Master which I/O data
the gateway supports.
All I/O data are selectable
through so called modules,
each described with its par-
ticular function.
Digital Input, Digital output,
Analog input and Analog
Output. Through this, the
individual configuration of
the Gateway is quite simpli-
fied, as the user only has to
select which I/O modules to
use. The supported modules
may be selected in any order
and any combination.
The G38910021 gateway
supports one Digital input
module, and One Digital out-
put module, corresponding
to the 128 channels of input
and output data. Furthermore,
56 Multiplexed analog inputs
and 56 analog outputs are
supported as well, and this
is done through additional 7
analog Input modules
named "AIn (Mux:CD,0-
7/Alink:AB)", "AIn
(Mux:CD,8-F/Alink:CD)" ...
"AIn (Mux:IJ,0-7/Alink:MN)"
and 7 analog output mod-
ules named "Aout (Mux:CD,0-
7)", "Aout (Mux:CD,8-F)" ...
"Aout (Mux:IJ,0-7)".
All modules consist of 16
bytes of data, and the tables
below describe the content
and the relations to the
Dupline data.
If the Dupline signal is
short-circuited, the gateway
will set the input status of all
channels to OFF, and issue a
Diagnostics information to
the Profibus master.
