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 compati-
2
bility 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 con-
nected 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 output(s) coded for
B5 will also be activated.
Consequently, a Dupline®-output can either be activated through the output-data received
on PROFIBUS-DP or by an
active Dupline® input coded for
the same Dupline®-address.
In “Split I/O” mode, the
Dupline-inputs and Dupline®outputs are treated independently by the channel generator. 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.
in “Bit-wise” mode, since the
AnaLink values are not transmitted as bit-combinations.
available, since it takes two
bytes to represent one of the
up to 112 multiplex values.
1 x DIP-switch for selection of
Dupline® Data Transfer Mode.
If “Sequence-wise” is selected, the transfer of data between Dupline® and PROFIBUS-DP only takes place
inbetween Dupline® I/O scansequences. This means that
the Dupline® I/O-data transmitted on PROFIBUS-DP will
always originate from the
same I/O scan-sequence.
This mode must be selected if
bit-combinations representing
e.g. analog values are transmitted on Dupline®. If “Bitwise” is selected, then the
transfer of data between Dupline® and PROFIBUS-DP takes
place continuously on-line with
the Dupline® I/O scan-sequences. In this way, the data-transfer speed between Dupline®
and PROFIBUS-DP is optimized. The “Bit-wise” mode should be selected if no bit-combinations representing analog
values are transmitted on
Dupline®.
Note: It is allowed to use
AnaLink sensors/transmitters
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.
All digital and analog inputs
can be transmitted on PROFIBUS-DP. Since the user knows
which channels are used as
digital and which channels are
used as analog, he also knows
where to find the meaningful
data on PROFIBUS-DP. If e.g.
an AnaLink temperature sensor is coded for channel B5,
the temperature value must
be read in the AnaLink dataarea. The status of channel
B5 can also be read in the
digital data-area, but the data
will not be meaningful.
Dupline® Input Data
A part of the Gateway inputprocessor reads all the 128
Dupline®-channels as digital
inputs (16 bytes) and another
part reads all the 128 Dupline®-channels as analog inputs. If the AnaLink analog
protocol is selected, 128 analog input-bytes will be
available, since it takes one
byte to represent one AnaLink value. If the multiplex
analog protocol is selected,
224 analog input-bytes will be
A part of the PROFIBUS-DP
Master configuration is to
define how many input-bytes
the Master shall receive from
each slave-module in the system. If e.g. no analog transmitters are connected to a
Gateway, it can be defined
that only the 16 bytes containing digital data shall be transmitted. In this way, the transmission of the analog inputbytes without meaningfull
information is avoided.
In the first table below, it is
defined how to read the digital
status of the individual Dupline®-channels on PROFIBUSDP. The digital input-data are
always transmitted as the first
16 bytes (byte-adresses 0..F).
The number of analog inputbytes depends on the selected
protocol (AnaLink: 128 bytes,
multiplex: 224 bytes), but they
are always located from byteaddress 10h and upwards. The
AnaLink values are represented as simple 8-bit values with
0 corresponding to the lowest
value and FFh corresponding
to the highest value. The multiplex values are represented
as 16-bit “sign and magnitude”-values. The most significant bit defines the sign (0:+,
1:-) while the remaining 15 bits
defines
the
magnitude
(0..32768).
The second and third table
below define how to read the
analog Dupline® values on
PROFIBUS-DP when respectively AnaLink or multiplex
protocol is selected.
