DDL General
2DDL General
The Drive & Diagnostic Link (DDL) from AVENTICS is a system to
use solenoids, pressure control valves and digital and analog
I/O modules with different field bus systems. Independent from
the used field bus, the systems can be projected and with the
corresponding bus coupler connected to common field busses
like PROFIBUS DP, Interbus S, ControlNet and DeviceNet. DDL
provides, independent from fieldbus, 128 inputs and 128
outputs per bus coupler. For the reason of the transfer mode
system, there is a high data security which is even increased by
the diagnostic functionality. In this way the DDL participants and
the supply voltages are controlled and reported to the
diagnostics. Furthermore the coils of valve units are observed
according to open load and short circuit. Therefore errors can
be quickly recorded up to the affected valve and measures
initiated. In addition some DDL participants offer the possibility
to determine via parameter the reaction upon failure of fieldbus
and DDL. On the basis of the employment of M12 connectors the
connection is very simple and safe. A total length of the cable of
40 m is permitted and offers a high flexibility with the DDL. Here
the gap between the modules is regardless. Because of the high
modularity most of the AVENTICS valve families can be
employed with DDL.
English
2.1DDL System Overview
Basically the DDL consists of two types of participants:
W The bus coupler makes it possible to transfer data between
the fieldbus system (PROFIBUS DP, Interbus S, DeviceNet, ...)
and the DDL. The bus coupler is therefore the DDL master
and has to be existent once.
W The DDL participant is therefore the slave within the DDL
system. Up to 14 participants can be connected to the DDL.
12AVENTICS | DDL | R499050031–BAL–001–AH
DDL General
The bus coupler with drivers contains, in addition to the Master
module, which is the real bus coupler, also a Slave module
which represents the DDL participant. This Slave module is
therefore a DDL participant and up to 13 other DDL participants
can be connected.
2.2DDL Addressing
In the DDL system a definite address has to be assigned to each
participant (except for the Master module of the bus coupler).
This is effected via a hex rotary switch at the devices.

The addressing can be effected in two different ways:
1. Manual addressing
2. Automatic addressing
AVENTICS | DDL | R499050031–BAL–001–AH13
Manual and automatic addressing cannot be effected at the
same time.
Please take into consideration that upon effecting the address
adjustments, changes will only be taken over after a reset of
voltage.
2.2.1Manual Addressing
A definite address, between 1 and 14, is allocated to each
participant. No participant must have the address 0.
Furthermore the lowest address must be 1 and there must not
be any gaps between the addresses. The addressing is,
however, independent from the physical position of the
participant in the DDL and its type.
Example: 5 DDL participants are connected to a bus coupler
Stand alone (needs no DDL address).

2.2.2Automatic Addressing
If there is only one participant per type in the DDL system, the
DDL can automatically address itself. For this the address 0 has
to be allocated to all DDL participants. In this case the DDL
system allocates the address automatically to the participants.
The following table shows, what kinds of module types are
available and where to find them in the data and the diagnosis
range.

2.2.3Error Upon Addressing
In order that the DDL is able to recognize and control all
participants, the above mentioned regulations have to be
observed. If the DDL has not been addressed correctly, this will
be indicated by the participant’s red DDL LED. If two participants
have the same address, this cannot be recognized that safely
that the DDL gets not into Run mode. This type of wrong
addressing can be recognized by checking the number of
livebits. In case of a DDL communication diagnosis, the
addressing of all participants shall be checked. Furthermore
the same baud rate has to be adjusted with all participants, also
with the Master module. In addition it has to be checked that all
cables have been correctly connected. Upon problems with very
long cables we recommend to run the DDL with 125 kBaud. For
further information on the baud rate adjustments, please refer
to the description of the device.
AVENTICS | DDL | R499050031–BAL–001–AH15
DDL General
2.3DDL Diagnosis
The DDL participants/bus couplers have two kinds of diagnosis.
On the one hand, each DDL device has LEDs to indicate the
diagnosis visually. On the other hand the DDL participants send
diagnosis data via the DDL to the bus coupler, which transmits
its own data and the diagnosis data of the DDL participants to
the control. The meaning of the diagnosis data and further
information can be taken from the corresponding chapters. The
DDL communication respectively the availability of the DDL
participants is constantly controlled by the bus coupler. As soon
as all configured DDL participants exist and communicate, the
red DDL LED turns off. If a participant does not communicate
any more, the red DDL LED will light at the corresponding
participant and the bus coupler reports the interference. In
addition the corresponding livebit and the DDL LED at the bus
coupler (Master module) lights (if existing). The communication
to the other DDL participants will however be maintained. If the
bus coupler recognizes the recurring participant (DDL LED at
the participant will go off), that way the configuration will be all
right, the DDL LED at the bus coupler will also go off.
In order to initialize the system correctly, the valves must not be
controlled. All supply voltages must exist correspondingly.
2.4DDL Data
2.4.1DDL Connection
The connection of the DDL is effected via 5 pin M12x1 plugs.
5-wire, shielded lines have to be used as connecting cables. The
shield has to be connected to the thread of the plug. The
diameter of the wires is 0.34 mm
connection is performed by a mounting male plug and the DDL
OUT connection as mounting female plug at the DDL
participants. As DDL participants can be damaged if 24 V are
applied to the signal line DDL H and DDL L or the supply lines
have been exchanged, we recommend to use pre fabricated and

2.4.2DDL Cable Length
The total cable length of DDL system is limited to 40 m. Thereby
it is irrelevant, whether the length between the two participants
will be used or distributed equally.
With great cable length and great consumption of electricity, the
voltage drop over the cables can provoke, that the supply
voltages at the DDL participants fall below the respective
tolerance limits. In such cases the DDL valve drivers can be
used with an external power supply (337 500 015 0 or
1 827 030 190 0), which, because of the additional supply,
indicate the voltage supply level.
2.4.3DDL Cycle Times
DDL is constructed for a fast and secure data transfer. The DDL
cycle times depend on several parameters. In that way the baud
rate, number of participants and configured in and output data
length (max. 128 bit) have influence on the cycle time.
In table 4 some applications and the corresponding DDL cycle
times are shown.
The process times in the bus coupler (approx. 0.8 ms) and the
cycle time of the field bus are not included in this overview. The
cycle time can be seen as an average value. With an ideal data
transmission the signal can be transmitted considerably earlier.
With critical applications it should be taken into consideration
that with an unfavorable data transmission it could take a cycle
time twice as long, until the signals are output or transmitted to
the field bus.

The DDL system fulfills the standards for EMC, listed below:
W EN 61000-6-4
W EN 61000-6-2
3Bus Coupler
AVENTICS bus couplers allow to connect pressure control
valves, valve units and digital and analog in and output modules
to a programmable logic control (PLC) by using a field bus
system like PROFIBUS DP, Interbus S, ControlNet, DeviceNet,
CANopen,... . One advantage of a serial control is the saving of
the parallel output cards in the PLC as well as the necessary
wiring. Another one is the possibility to transfer further
information like Diagnosis and parameters.
Bus couplers are available in two different designs. On the one
hand there is the Stand alone module. It consists only of the
Master module. The Master module communicates with the
field bus system and controls the DDL. On the other hand bus
couplers with drivers to control the valve via a 25 pin D-Sub
plug, are available. They have, in addition to the Master module,
also a Slave module which operates like a single DDL
participant, but is situated within the same housing.

3.1PROFIBUS DP 337 500 025 0/337 500 026 0
The bus coupler for PROFIBUS DP is available in two different
designs. The bus coupler with drivers (337 500 026 0) can be
directly mounted onto a valve unit. Apart from controlling this
unit, the DDL is also available for other DDL participants.
The bus coupler Stand alone (337 500 025 0) is mounted
separately and offers only the DDL. The parts of description of
the Slave module, do not apply to the bus coupler Stand alone.
Both modules are connected to the PROFIBUS DP via a shielded
2 wire cable.
3.1.1Overview
PROFIBUS DP
The field bus system PROFIBUS DP which is used for the
communication with the control, is a fast working bus system
for the cyclic exchange of user data. PROFIBUS DP is a master
slave bus system, where 2 master and 122 passive participants
maximum can be connected to. Two designs as transmission
medium are available:
W 2 wire line (shielded)
W optical fibre
For installation information of the networks and for the
configuration of the lines, please refer to the documentation
of the PROFIBUS association. http://www.profibus.com
The Master module is the interface between the PROFIBUS DP
and the DDL. It controls the DDL and monitors the supply
voltages.
PROFIBUS DP Addresses
Before a connection to the PROFIBUS DP System, an address
will have to be assigned to the bus coupler. After opening the
sealing cap, the address is assigned by two rotary switches.
Addresses from 0 ... 99 can be assigned. With switch S1 the ten
digit is set, with S2 the one digit is set. In the factory the devices
are already adjusted to address 3.
English
20AVENTICS | DDL | R499050031–BAL–001–AH
Bus Coupler
The switches must not be changed during operation.
Changed switch positions will only become valid, after the
device has been turned off and restarted.
PROFIBUS DP – Baud Rates
The PROFIBUS transfer rates are adjusted with the PROFIBUS
master (PLC) and are then automatically recognized by the slave
(bus coupler). The following values can be adjusted as rates of
transmission:
For the PLC configuration software, e. g. COM PROFIBUS the
device master file RXP_05EF.gsd will be needed. This file is
included in the delivery or can be ordered separately under the
following no.: 546 046 941 2. The file has to be copied into the
directory which was defined by the PLC configuration software.
On this disk are also two Icon files for this bus coupler
(RX_D05EF.dip/RX_R05EF.dib).
For the configuration of the bus coupler, the type of station bus
coupler has to be selected (above folder Valves/AVENTICS).
After selection of the field "configuration" and modules, the
corresponding DDL modules have to be inserted. Each
participant of the DDL has to be singly configured as a module.
The DDL participant with address 1 has to be configured as
module 0, participant 2 as module 1 etc.
Combi modules need 2 modules, but only one DDL address.
Thereby the number of the module moves one digit per
module towards the DDL address.
Also the length of the data of the valve unit and the input module
must be correctly adjusted. Arbitrary addresses in the address
area of the control can be assigned to each module (if the
control permits this).
If the configuration differs from the real DDL system, the bus
coupler will not be recognized correctly by the PROFIBUS
master!
AVENTICS | DDL | R499050031–BAL–001–AH21
Parameter
These functions are deposited in the GSD file and can be
displayed as plain text via a configuration tool (e.g. COM
PROFIBUS or S7 Hardware configuration). Per each DDL
participant one byte is transferred and also one byte for the bus
coupler. Each single parameter byte for the participants can be
individually adjusted. If no parameters are adjusted, the DDL
participants use their default parameter.
Changed parameters only become valid if the device has been
turned off and on again.

Software DiagnosisIn case of error, an „EXT_DIAG“ message is send via the
PROFIBUS DP, to the control. The length of the ext. diagnosis
message depends on the number of participants. For the bus
coupler Stand alone 337 500 025 0 the length is 4 byte diagnosis
+ 1 byte header (PROFIBUS Norm). After the bus coupler the
diagnosis for the participants is sorted upwards, according to
the DDL addresses. For each further DDL participant the
commensurate diagnosis bytes are added. The diagnosis length
of a valve driver consists of 1 Byte + the configurated data
length. The Diagnosis data length for other DDL nodes can be
read up on the corresponding chapters.
The bus coupler with drivers (337 500 026 0) behaves like the
Stand alone module and an additional DDL participant for valve
control (see Slave Module).
To use the diagnosis function, the corresponding parameter has
to be adjusted (see table 5, parameter for the bus coupler).

Output Data Range of the Control
The DDL address determines the position of the output data in
the data range of bus coupler and therefore the position in the
address range of the control. The valve driver occupies,
depending on the length set, 1 ... 4 byte in the output range of the
control. Whereby the 4th byte does not represent real outputs
and serves only for the 16 bit conformity.
At Pin 25 of 25 pol. D-Sub plug 0 V is connected.
If address 0 (automatic addressing) is set, the bus coupler with
driver behaves like a valve driver. Further information can be
taken from chapter 2.2 “DDL Addressing“.
The valve driver does not occupy any data in the input range,
only within the diagnosis range of the DDL.
Byte X is the start address of the output data range of the DDL
participant in the control (see PROFIBUS DP Configuration).

Parameter
The Slave module provides the DDL master module for
PROFIBUS DP with these functions. For each DDL participant
one byte for parameter is available. The parameters are
transferred only with the DDL initialization. Each parameter
byte for the participants can be adjusted individually. In
connection with the PLC the PROFIBUS provides comfortable
possibilities for adjustment. If the control does not provide these
functions, default parameters will be used.

Bit 1 = 0Output based diagnosis messages are only sent, if the output is
controlled. Upon starting the system it is not checked, which
coils do exist. If an output is controlled, where no coil exists, a
diagnosis message is generated.
Bit 1 = 1Upon starting the system it is first determined what coils do
exist. This information is then transferred via a diagnosis
message to the control. In the control this message can be
compared with a deposited configuration of the system. (This
function is only supported by PROFIBUS DP; with other field bus
systems the diagnosis data are transferred cyclic). Missing coils
can be determined upon the start of the system. During the
cyclic operation only diagnosis messages are sent, if there have
been changes according to this configuration. Thereby the
complete diagnosis range is transferred. Open load is
immediately reported, the valve needs not to be controlled.

The electronics of the bus coupler and the electronics of all

without ext. power supply) are supplied via X1S, pin 1.
If modules without an external power supply are used, the
switching voltage for connected valves must be supplied via
X1S, pin 2.Because of the separate supply of this power supply
it is possible, in an emergency stop situation, only to turn off the
valves, whereas the PLC, the serial interfaces and the initiators
remain in operation. Turning off the power supply for the serial
interface can lead to the state STOP of the PLC.
The 24 V supplies must be effected out of a common power
supply unit respectively with a common O V connection. A
power supply unit with a secure separation according to
EN 60742, classification VDE 0551 should be used.

resistor is designed for a PROFIBUS DP cable of type A (wave
resistance 135 ... 165 Ω) and integrated into the end plug.
Data Line DDL
The output of the DDL is short circuit protected at all lines.
Nevertheless DDL participants can be damaged if 24 V are
applied to signal lines DDL H and DDL L. For this reason it is
recommend to use pre fabricated cables (see chapter 5 “DDL
Accessories“). The allocation of the DDL connections are
described in chapter 2.4 “DDL Data“.
The DDL end plug (see chapter 5 “DDL Accessories“) is
necessary to guarantee a definite termination of the line and the
protection degree IP 65, if the module is the last or the only
participant of a DDL line.

3.1.7ATEX-Relevant Information
If the bus coupler PROFIBUS DP 337 500 025 0 is used in zone 2,
attention has to be paid to the following ATEX-relevant
information.
See chapter 3.6.1 “Ex-Relevant Excerpt from the Operating
Instructions for S-Design Bus Couplers“.
3.2DeviceNet R412006999/R412006998
The bus coupler DDL for DeviceNet is available in two different
designs. The bus coupler with drivers (R412006998) can be
directly mounted onto a valve unit. In addition to the control of
this unit the DDL is also available for other DDL participants.
The bus coupler Stand alone (R412006999) is separately
mounted and provides only the DDL.
Parts of the description concerning the Slave module are not
valid for the bus coupler Stand alone.
3.2.1Overview
DeviceNet
DeviceNet is a CAN protocol that is based on a definite master/
slave connection. Several masters can share a physical CAN
data line and control several slaves. A slave though is always
dedicated to one master and can only exchange data with this
one. A master must first release a slave before another master
is able to ask for the slave and activate him.
The electronic data sheet (EDS) can be downloaded from the
Internet at www.aventics.com/mediadirectory:
0064000000040205.eds
Type: EDS Configuration File
For information concerning the installation of the network and
regarding the preparation of the line, please refer to the
documentation of the company Rockwell Automation/AllenBradley.
The Master module is the interface between the DeviceNet and
the DDL. It controls the DDL and monitors the supply voltages.

DeviceNet Addresses
A definite address is allocated to each participant in the
network. Via two rotary switches addresses from 0 ... 63 can be
set. With switch S1 the ten digit and with S2 the one digit is
adjusted. If the ID has been adjusted higher, it is reduced by 64.
In the factory the devices are adjusted to address 2.

DeviceNet Data
The length of the output data range (valves, nominal value, ...) is
fixed to 16 byte (10 hex) maximum. The length of the input data
range (sensors, actual values, ...) is also adjusted to 16 byte
maximum. Due to the diagnosis data of the bus coupler and the
DDL participants the total input data range is enlarged up to
50 byte (32 hex). The diagnostic data is transmitted cyclic within
the input data range to in the PLC.
Parameters
Some field bus systems offer the possibility to transfer
parameters to the bus coupler and the DDL participants.
At present the bus coupler for DeviceNet does not offer this
opportunity.
Bus Coupler Parameters
The bus coupler does not provide parameters for a modification.
Upon a failure of the DeviceNet the bus coupler behaves that
way that all output data are set at 0. Diagnostic data are
transmitted cyclic within the input data.

DDL Participants Parameters
As with the bus coupler there is no parameter transfer for the
DeviceNet available, the default parameters are used with all
DDL participants. They are mentioned in the corresponding
device descriptions.
DDL Address
At the Master module, respectively Stand alone bus coupler, no
DDL Address has to be set.
For correct function of the DDL (Drive & Diagnostic Link)
following items must be fulfilled:
W same Baud rate at all DDL modules
W DDL Address within 1 ... 14, starting with 1, without gap, no
double used Address
W DDL Address 0: see chapter 2.2 “DDL Addressing“
DDL Mode
The transfer rate of the DDL is set with the 4 bit DIP switch S4
next to the D-Sub plug at the back side. All participants must be
adjusted to the same baud rate.
For access to switch S4 at the bus coupler Stand alone
R412006999 the bottom plate has to be removed.

Software DiagnosisAfter activating the power the configuration of the DDL is
determined. Thereby the figure and the address of the
connected DDL participant, its data length and the type is
ascertained. After approx. 5 sec this configuration is redone and
compared to the first one. A difference of the determined
configurations is reported as a configuration error (byte 0, bit 5).
In addition the configuration is also examined when the total
output data range is set at 0 for more than 5 sec (set value = 0).
The in- and output data of the participants will not be influenced
thereby.
The software diagnosis of the Master module can be found in
the first 4 bytes of the adjusted input data area of the control,
before the input data. The whole software diagnosis of the other
DDL participants is behind the input data area of all DDL
participants. The length of the diagnosis range of further DDL
participants is 1 byte + the adjusted output data length with
valve driver. With other participants the diagnosis length can be
taken from the corresponding descriptions.

3.2.3Slave Module
The Slave module behaves like a DDL participant for valve

According to this a DDL address has to be adjusted! The

Output Data Range in the Control
The DDL address determines the position of the output data in
the data range of the bus coupler and therefore the position of
the address range of the control.
The valve unit occupies, depending on the adjusted length,
1 ... 4 bytes of the output range. Whereby the 4th byte does not
represent real outputs and serves only for the 16 bit conformity.
0 V is connected to pin 25 of the 25 pole D-Sub plug.
The switches must not be changed during operation.
Changed switch positions will only become valid, after the
device has been turned off and restarted.
If address 0 (automatic addressing) is set, the bus coupler with
driver behaves like a valve driver. Further information can be
taken from chapter 2.2 “DDL Addressing“.
The valve unit does not occupy any data in the input range, only
within the diagnosis range of the DDL.
Byte X is the start address of the output data range of the DDL
participant in the control.

Software DiagnosisThe diagnosis data of the Slave module are situated behind the
data of the input range, corresponding to the DDL address. If
address 0 (automatic addressing) is set, the bus coupler with
driver behaves like a valve driver. Further information can be
taken from chapter 2.2 “DDL Addressing“.
The software diagnosis of the Slave module is 1 byte standard
diagnosis + configured data length long.
With bus coupler R412006998 the outputs from 24 ... 31 are not
really existent. For this reason there is no rational diagnosis.
With smaller valve units further outputs and their diagnosis can
not be used.

A short circuit can only be recognized if the output is driven.
An open output can only be recognized if it is not driven.
Parameter
As a parameter transmission is not available for the bus coupler
for DeviceNet, the default parameter are used for all DDL
participants.
W The default parameters are:
– Reaction upon DDL failure: values at 0
– Diagnosis message coils: at driven outputs
The connectors must not be plugged or pulled under load.
The assembly or the plugging and pulling of the bus coupler
onto the valve unit is only allowed when the device is off
circuit!
Power Supply
The power supply is connected via a circular plug X1S. Only
4 pin M12 connecting bushes should be used, whereas pin 5 is
closed in order to avoid a mix up with other connections. The
diameter of the wires should be chosen as big as possible, but
at least 0.5 mm
Both power supplies must be secured with external 3 A T fuses.
The maximum allowed current in the O V line is limited to 4 A by
the connector.

The electronics of the bus coupler and the electronics of all
I/O modules and initiators connected to the DDL (with modules
without ext. voltage supply) are supplied via X1S, pin 1.
Via X1S, pin 2 the voltage for the valves must be supplied, if no
module with external power supply is used. Because of the
separate supply of this power supply it is possible, in an
emergency stop situation, only to turn off the valves, whereas
the PLC, the serial interfaces and the initiators remain in
operation. Turning off the power supply for the serial interface
can lead to the state STOP of the PLC.
The 24 V supplies must be effected out of a common power
supply unit respectively with a common O V connection.
A power supply unit with a secure separation according to
EN 60742, classification VDE 0551 should be used.

Data Line DDL
The output of the DDL is short circuit protected at all lines.
Nevertheless DDL participants can be damaged if 24 V are
applied to the signal lines DDL H and DDL L. For this reason we
recommend to use pre configured cables (see chapter 5 “DDL
Accessories“). The allocation of the DDL connections is
described in chapter 2.4 “DDL Data“.
The DDL end plug (see chapter 5 “DDL Accessories“) is
necessary to guarantee a definite termination of the line and the
protection degree IP 65, if the module is the last or the only
participant of a DDL line.

3.2.7ATEX-Relevant Information
If the bus coupler DeviceNet R412006999 is used in zone 2,
attention has to be paid to the following ATEX-relevant
information.
See chapter 3.6.1 “Ex-Relevant Excerpt from the Operating
Instructions for S-Design Bus Couplers“.
3.3Interbus S 337 500 045 0/337 500 046 0
The bus coupler for Interbus S is available in two different
designs. The bus coupler with drivers (337 500 046 0) can be
directly mounted onto a valve unit. In addition the control of this
unit the DDL is also available for other DDL participants.
The bus coupler Stand alone (337 500 045 0) is separately
mounted and provides only the DDL. Parts of the description
concerning the Slave module are not valid for the bus coupler
Stand alone.
3.3.1Overview
Interbus S (IBS)
In the Interbus S process the data are serially pushed, in a
closed loop, through all participants until they reach the
dedicated address. There the output data (valve data) will be
verified regarding faults, will then be output and replaced by
input data (sensor state). These input data will be pushed into
the master in the next cycle whereas at the same time the new
output data are input into the loop. This principle permits to
send and receive during one cycle. Upon initialization all length
codes of the participants are read and recorded. The number of
reference data per participants and the number of the
participants has always to remain constant. The bus coupler is
integrated into the Interbus S system as remote bus participant.
A connection to a periphery bus is not possible.
Due to the word orientation of the in and output data there will
be an exchange of high and lowbyte with byte oriented PLC

types (e. g. Siemens S7). If, for example, the address 30 has
been allocated as data word, bits 0 ... 7 will appear in address
For information regarding the network build up and the
packing of the lines, please refer to the documentation of
the company Phoenix Contact or the Interbus Club.
The Master module is the interface between the Interbus S and
the DDL. It controls the DDL and monitors the supply voltages.
Interbus S Addresses/Last Participant
The Interbus S address of the bus coupler results from the
position in the Interbus S system and can only be changed
through a change in the sequence of the participants. On
insertion or removal of a participant the addresses move within
the ring.
If the bus coupler is the last participant in the Interbus S, the
module must be correspondingly configured with switch S2.

Interbus S Parameter
The bus coupler behaves like a digital in/output unit and reports
back as a module type (identification) 03H.
The length code of the bus coupler has to be firmly set for
Interbus S, as the Interbus configuration depends on this.
Depending on the used data length of the DDL participant the
Interbus length code of the bus coupler can be optimized. The
length code is configured to the maximum unit’s stage of
expansion of 10 words (length code 0AH). This length code is
adjusted with switch S1.
The length code has to be calculated via the DDL configuration
through the user, before initial operation.
The length code has to be determined as follows:
The maximum length can be calculated with the output data
length plus 1 byte (diagnostic request without parameter
transmission) respectively 4 byte (diagnostic request with
AVENTICS | DDL | R499050031–BAL–001–AH55
Bus Coupler
parameter transmission) or the input data length plus 4 byte
diagnosis address and – data. Here the greater value has to be
used.
The in or output data range is the result of all data lengths of
employed DDL participants.
How the different data ranges are composed can be taken from
the corresponding chapters.
The data length in the DDL refers to bytes. The
configuration of bus coupler‘s length code is adjusted word
wise. Uneven byte sums have to be rounded up!
Example configuration for length code determination:
Parameters shall be transferred.

Parameter
The Interbus S does not offer a special possibility to transfer
parameter to the bus coupler. For this reason it is not possible
to parameterize the Master module. There is, however, an
option to configure the parameters of the DDL participants or
the Slave module via the Interbus. This can be effected via the
output data field of the bus coupler (see table 27).
The parameterization of the DDL participants can be activated
at the bus coupler. If the parameter transmission is not
activated, the DDL participants use their default parameter. The
parameter transmission is adjusted with switch S1 bit 7.

Bus Coupler Parameter
The Master module does not provide parameters. With

DDL Participants Parameter
The parameter descriptions of the different DDL participants
can be taken from the corresponding chapters.
Parameter Transmission
In order to transmit parameter to the DDL system, the Master
module has to be configured correspondingly (see table 26).
Upon activated parameter transmission, all required
parameters and the check sum (sum of all parameter bytes) has
to be correctly transmitted first, (bytes 0 ... 13: parameter bytes
of the single DDL participants (1 ... 14), byte 14: check sum),
before the DDL system will be initialized. It is recommended to
transmit all 14 parameter bytes and the checksum always. For
not used parameter bytes 00h has to be used. If the calculated check sum has the value 01, 55 must be send instead! If no
parameters have been sent, or if the checksum is not ok, this is
reported via the diagnosis to the control. By way of security
parameters shall be sent several times. Only the values sent
last will be valid. The sequence the parameters are transmitted
is not relevant.
The parameter bytes can be transmitted single or pair wise (see
output data field parameter byte X and X+1).
As soon as the DDL is initialized parameters cannot be changed
any longer. The parameter values and their meaning can be
taken from the documentation of the DDL participants.
The checksum results from the sum of the single parameter
bytes (without overflow).
The change of parameter data is only possible after a voltage
reset of the Master module.
At the Master module respectively. Stand alone bus coupler no
DDL Address has to be set.
For correct function of the DDL (Drive & Diagnostic Link)
following items must be fulfilled:

double used Address
W DDL Address 0: see chapter 2.2 “DDL Addressing“

supply voltages are controlled independently from each other. If
the short circuit monitoring in the bus coupler is activated, the
corresponding LED will start to flash.
Software DiagnosisThe complete diagnosis range is deposited in the DDL. This can
be requested via the in and output data fields. The diagnosis
area can be calculated from the sum of all single diagnosis
areas. Thereby it has to be taken into consideration, that also the
bus coupler (Master module) provides 3 bytes of diagnosis data.
The length of the single participants can be taken from the
corresponding descriptions.
AVENTICS | DDL | R499050031–BAL–001–AH63
After power up the configuration of the DDL will be determined.
Thereby the figure and the address of the connected DDL
participants, their data length and their type will be determined.
After approx. 5 sec this configuration will be redone and
compared to the first one. A difference between the determined
configurations will be reported as configuration error (byte 0,
bit 5). The configuration will also be verified, if the total output
data range is set at 0 (set value = 0), for more than 5 sec. The in

3.3.3Slave Module
The Slave module behaves like a DDL participant for valve
control but it is situated within the housing of the bus coupler.
According to this a DDL address and a baud rate have to be
adjusted! The connection to the valve unit is effected via a 25 pin
D-Sub plug at the bottom side of the module.
DDL Address
The DDL address is adjusted with the switch S4. The regulation for
the adjustment can be found in chapter 2.2 “DDL Addressing“.
DDL Mode
The DDL baud rate is adjusted with switch S3. All participants
have to be adjusted to the same baud rate.

The switches must not be changed during operation.
Changed switch positions will only become valid, after the
device has been turned off and restarted.
Output Data Range in the Control
The DDL address determines the position of the output data in
the data range of bus coupler and therefore the position in the
address range of the control. The valve driver occupies,
depending on the length set, 1 ... 4 byte in the output range of the
control. Whereby the 4th byte does not represent real outputs
and serves only for the 16 bit conformity.
At Pin 25 of 25 pol. D-Sub plug 0 V is connected.
If address 0 (automatic addressing) is set, the bus coupler with
driver behaves like a valve driver. Further information can be
taken from chapter 2.2 “DDL Addressing“.
The valve driver does not occupy any data in the input range,
only within the diagnosis range of the DDL.
Byte X is the start address in the output data range of the DDL
participant in the control.

The limits of power supply (electronics/valves) are at 19.2 V/
21.6 V for low voltage and at 28.8/26.4 V for overvoltage. The
voltages are measured at plug DDL OUT. The LED DDL indicates
that no reference data communication takes place in the DDL
system. This can be due to:
W The adjusted baud rate of the DDL modules is not equal
W Gaps in the addressing
W Same address has been assigned for 2 modules
W Address 0 and 1 ... 14 have been assigned at the same time
W Configuration has changed during operation

Software DiagnosisThe diagnosis data of the Slave module are in the diagnosis data
range according to the DDL address. If address 0 (automatic
addressing) is set, the bus coupler with driver behaves like a
valve driver. Further information can be taken from chapter 2.2
“DDL Addressing“.
The length of the diagnosis range is 1 byte + the adjusted output
data length. With bus coupler 337 500 046 0 the outputs 24 ... 31
do not really exist. For this reason there is no rational diagnosis.
With smaller valve units further outputs and their diagnosis can
not be used.

Parameter
The Slave module provides the DDL master module for
Interbus S with these functions. For each DDL participant one
byte for parameter is available. The parameters are not
transferred cyclically. The parameter byte can be adjusted
individually for each participant. With the Interbus S bus coupler
the parameter of the DDL participants can be configured via the
output data field If the parameter transmission is deactivated,
the Slave module uses default parameter.

If modules without an external power supply are used, the
switching voltage for connected valves must be supplied via
X1S, pin 2. Because of the separate supply of this power supply
it is possible, in an emergency stop situation, only to turn off the
valves, whereas the PLC, the serial interfaces and the initiators
remain in operation. Turning off the power supply for the serial
interface can lead to the state STOP of the PLC.
The 24 V supplies must be effected out of a common power
supply unit respectively with a common O V connection.
A power supply unit with a secure separation according to
EN 60742, classification VDE 0551 should be used.

Data Line DDL
The output of the DDL is short circuit protected for all lines.
Nevertheless DDL participants can be damaged if 24 V is
applied to signal lines DDL H and DDL L. For this reason we
recommend to use pre configured cables (see chapter 5 “DDL
Accessories“). The allocation of the DDL connectors is described
in chapter 2.4 “DDL Data“.
The DDL end plug (see chapter 5 “DDL Accessories“) is
necessary to guarantee a definite termination of the line and the
protection degree IP 65, if the module is the last or the only
participant of a DDL line.

3.3.7ATEX-Relevant Information
If the bus coupler Interbus S 337 500 045 0 is used in zone 2,
attention has to be paid to the following ATEX-relevant
information.
See chapter 3.6.1 “Ex-Relevant Excerpt from the Operating
Instructions for S-Design Bus Couplers“.
3.4ControlNet 337 500 056 0
The bus coupler for ControlNet is available in two different
designs. The bus coupler with drivers (337 500 056 0) can be
mounted directly onto a valve unit. In addition to the control of
this unit, the DDL is also available for further DDL participants.
The bus coupler Stand alone (order number on request) is
separately mounted and provides only the DDL. Part of the
description concerning the Slave module are not valid for the
bus coupler stand alone except for the monitoring of the voltage.
3.4.1Overview
ControlNet
The ControlNet which is used for communication with the
control, is a fast working bus system to interchange time critical
user dates. It offers not only real time data transmission but
also intelligence service for direct data interchange between
2 participants. As a transmission medium a 75 Ω coaxial cable,
terminated at both sides is used.
The device has to be driven at channel A and does not support
redundant cabling.
Concerning the information for the assembly of the network
and also for the preparation of the lines, please refer to the
documentation of the company Rockwell Automation/AllenBradley.
The Master module is the interface between the ControlNet and
the DDL. It controls the DDL and monitors the supply voltages.
ControlNet Address
A definite address is allocated to each participant in the
network. Via two rotary switches addresses from 0 ... 99 can be
set. With switch S1 the ten digit and with S2 the one digit is
adjusted. Address 0 and 1 are reserved for controls or for
temporary diagnosis devices and shall not be used. The devices
are already adjusted to address 2 in the factory.

ControlNet Baud Rate
The baud rate of the ControlNet is 5 MBaud and cannot be
changed.
ControlNet Parameter
The length of the output data range (valves, nominal value, ...) is
fixed to 16 byte (10 hex) maximum. The length of the input data
range (sensors, actual values, ...) is also limited to 16 byte
maximum. Due to the diagnosis data of the bus coupler and the
DDL participants the total input data range is enlarged up to
48 byte (30 hex). The diagnostic data is transmitted cyclic within
the input data range to in the PLC.

Parameter
Some field bus systems offer the possibility to transfer
parameters to the bus coupler and the DDL participants. At
present the bus coupler for ControlNet does not offer this.
Bus Coupler parameterThe bus coupler does not provide parameter for modification.
Upon a failure of the ControlNet the bus coupler behave in that
way, that all output data are set at 0. Diagnostic data were
transmitted cyclic within the input data.

Output Data Range in the Control
The DDL address determines the position of the output data in
the data range of the bus coupler and therefore the position of
the address range of the control.
The valve driver occupies, depending on the adjusted length,
1 ... 4 bytes of the output range. Whereby the 4th byte does not
represent real outputs and serves only for the 16 bit conformity.
0 V is connected to pin 25 of the 25 pole D-Sub plug.
If address 0 (automatic addressing) is set, the bus coupler with

taken from chapter 2.2 “DDL Addressing“.
The valve driver does not occupy any data in the input range,

Bus Coupler
The electronics of the bus coupler and the electronics of all I/O
modules and initiators connected to the DDL (with modules
without ext. voltage supply) are supplied via X1S, pin 1.
Via X1S, pin 2 the voltage for the valves must be supplied, if no
module with external power supply is used. Because of the
separate supply of this power supply it is possible, in an
emergency stop situation, only to turn off the valves, whereas
the PLC, the serial interfaces and the initiators remain in
operation. Turning off the power supply for the serial interface
can lead to the state STOP of the PLC.
The 24 V supplies must be effected via a common power
supply unit or with a common O V connector.
A power supply unit with a safety separation according to
EN 60742, classification VDE 0551.
Data Line ControlNet
The connection to the bus system is effected via the data plug
X7N. This is a BNC plug customary in the trade. For further
information we refer you to the documentation of the company
Rockwell Automation/Allen-Bradley.
Data Line DDL
The output of the DDL is short circuit protected at all lines.
Nevertheless DDL participants can be damaged if 24 V are
applied to the signal lines DDL H and DDL L. For this reason we
recommend to use pre configured cables (see chapter 5 “DDL
Accessories“). The allocation of the DDL connections is
described in chapter 2.4 “DDL Data“. The DDL end plug (see
chapter 5 “DDL Accessories“) is necessary to guarantee a
definite termination of the line and the protection degree IP 65,
if the module is the last or the only participant of a DDL line.

3.5CANopen R412008000/R412008002
The bus coupler for CANopen is available in two different
designs. The bus coupler with drivers (R412008002) can be
directly mounted onto a valve unit. In addition to the control of
this unit the DDL is also available for other DDL participants.
The bus coupler Stand alone (R412008000) is separately
mounted and provides only the DDL.
Parts of the description concerning the Slave module are not
valid for the bus coupler Stand alone.
3.5.1Overview
CANopen
The CAN profile CANopen was standardized by manufacturers
and the user association CAN in Automation (CiA) under the
number CiA DS 301.
Realtime data are transmitted with so called process and data
objects (PDO). Parameter data, diagnosis data and program
data are transmitted with Service data objects (SDO). Both
objects are transmitted with different identifiers, which are
based on the adjusted module ID.
A PDO consists only process data and no program overhead. A
SDO otherwise consists in addition to the process data also the
information which object has to be used. In addition to the
regular objects as START, STOP or RESET some further optional
objects are defined. For the PLC configuration software, the EDS
file may be helpful.
The electronic data sheet (EDS) can be downloaded from the
Internet at www.aventics.com/mediadirectory:
DDL_co.eds
Type: EDS Configuration File
English
For information concerning the installation of the network
and regarding the preparation of the line and used objects
please refer to the documentation of CiA Draft
Standard 301 from CAN in Automation e. V.
The Master module is the interface between the CANopen and
the DDL. It controls the DDL and monitors the supply voltages.
CANopen Address
A definite address is allocated to each participant in the
network. Via two rotary switches addresses from 0 ... 99 can be
set. With switch S1 the ten digit and with S2 the one digit is
adjusted. The address 0 reserved for CANopen diagnosis
functions and may not be used. In the factory the devices are
adjusted to address 2.

CANopen Baud Rates
The baud rate of the CANopen system is adjusted with the 2 bit
DIP switch S3 and with bit 2 of the 4 bit DIP switch S4 on the
back side of the master module. For access to switch S4 at the
Bus coupler Stand alone R412008000 the bottom plate has to be
removed.

CANopen Data
The length of the output data range (valves, nominal value, ...) is
fixed to 16 byte (10 hex) maximum. The length of the input data
range (sensors, actual values, ...) is also adjusted to 16 byte
maximum. With each TXD-PDO 8 data bytes are transmitted
respectively requested with each RXD-PDO. In the
communication area of the object dictionary the PDOs can be
found under the index 1401 respectively 1400 (Transmit) and
1801 respectively 1800 (Receive).
Additionally it is possible to force the output data in the
parameter area of the object dictionary with the index 6200 and
6300 within the subindexes 1 ... 8 each. The input data can be
requested with the index 6000 and 6100 also within the
subindexes 1 ... 8 each.

Parameter
The CANopen bus coupler provides the transmission of special
communication profile objects as e.g. NodeGuarding.

Bus Coupler Parameters
The bus coupler does not provide parameters for a modification
Upon a failure of the DeviceNet the bus coupler behaves that
way that all output data are set at 0.
DDL Participants Parameter
The parameters for the DDL participants can be transmitted
within the parameter area of the object dictionary with the index
2040. The transmission of all parameter must be finished
before the bus coupler is switched to Pre/Operational. 16 byte
data in four bloc within the subindexes 1 ... 4 are transmitted in
total. The first byte will be sent to the DDL participant with the
DDL address 1 when the bus coupler is switched to Operational.
The other follow according to the DDL address. If no parameter
data is defined the value 0 will be transmitted to the DDL
participants.
The meaning of the parameters are mentioned in the
corresponding device descriptions.
DDL Address
At the Master module, respectively Stand alone bus coupler, no
DDL Address has to be set.
For correct function of the DDL (Drive & Diagnostic Link)
following items must be fulfilled:
W same Baud rate at all DDL modules
W DDL Address within 1 ... 14, starting with 1, without gap, no
double used Address
W DDL Address 0: see chapter 2.2 “DDL Addressing“.
DDL Mode
The transfer rate of the DDL is set with the 4 bit DIP switch S4
next to the D-Sub plug at the back side. All participants must be
adjusted to the same baud rate.
For access to switch S4 at the bus coupler Stand alone
R412008000 the bottom plate has to be removed.

Software DiagnosisAfter the bus coupler has switched to Pre/Operational the
configuration of the DDL will be determined. Thereby the figure
and the address of the connected DDL participant, its data
length and the type is ascertained. After approx. 5 sec this
configuration is redone and compared to the first one. A
difference of the determined configurations is reported as a
configuration error (byte 0, bit 5). In addition the configuration is
also examined when the total output data range is set at 0 for
more than 5 sec (set value = 0). The in and output data of the
participants will not be influenced thereby.
The software diagnosis of the Master module can be found in
the diagnosis area of the object dictionary with index 2020. The
32 byte diagnosis data are transmitted in four bloc within the
subindexes 1 ... 8.
The length of the diagnosis range of further DDL participants is
1 byte + the adjusted output data length with valve driver. With
other participants the diagnosis length can be taken from the
corresponding descriptions.

Output Data Range in the Control
The DDL address determines the position of the output data in
the data range of the bus coupler and therefore the position of
the address range of the control.
The valve unit occupies, depending on the adjusted length,
1 ... 4 bytes of the output range. Whereby the 4th byte does not
represent real outputs and serves only for the 16 bit conformity.
0 V is connected to pin 25 of the 25 pole D-Sub plug.
If address 0 (automatic addressing) is set, the bus coupler with
driver behaves like a valve driver. Further information can be
taken from chapter 2.2 “DDL Addressing“.
The valve unit does not occupy any data in the input range, only
within the diagnosis range of the DDL.
Byte X is the start address of the output data range of the DDL
participant in the control.
