G 3891 0120
Mode of Operation
The Dupline PROFIBUS-DP
Gateway operates as
a PROFIBUS-DP slave
according to EN 50 170.
This means that the 128
Dupline
I/O's (incl. multi-
plexed analog signals) can
be read/controlled by
PROFIBUS-DP masters like
PLC's and PC interface-
cards from many different
suppliers. Since the
G38910120 is a passive
gateway without channel
generator function, it is pos-
sible to connect several
units to the same Dupline
network. The Dupline
PROFIBUS-DP Gateway is
approved by the PNO
(Profibus Nutzer Organisa-
tion) that ensures compati-
bility with other PNO-certi-
fied products.
Configuration switches
The unit is equipped with
the following switches:
1 x 16-position rotary
switch- not used in the
G38910120.
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.
4 x DIPswitches - not used
in the G38910120.
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_120.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_120.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 etc. Through
this, the individual con-
figuration of the Gateway is
quite simplified, 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 G38910120 passive
gateway supports one
Digital input module, and
one Digital output module,
corresponding to the 128
channels of input and out-
put data. Furthermore, the
G38910120 automatically
detects if Multiplexed
analog data are present on
the Dupline. Thus up to 112
Analog values may be read,
and this is done through
additional 14 Input modules,
named "AIn (Mux:CD,0-7)",
"AIn (Mux:CD,8-F)" ... "AIn
(Mux:OP,8-F)".
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
missing or faulty, the gate-
way will set the input status
of all channels to OFF.

The most significant bit defines the sign (0:+, 1:-) while the
remaining 15 bits define the magnitude (0..32768).
