DDL General
2 DDL 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
2.1 DDL 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.
12 AVENTICS | 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.
2.2 DDL 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.
Table 1: DDL address switch
Position of Switch Meaning
0 automatic addressing

C DDL address 12
D DDL address 13
E DDL address 14
F no function
The addressing can be effected in two different ways:
1. Manual addressing
2. Automatic addressing
AVENTICS | DDL | R499050031–BAL–001–AH 13
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.
2.2.1 Manual 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).

2.2.2 Automatic 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.

2.2.3 Error 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–AH 15
DDL General
2.3 DDL 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.
2.4 DDL Data
2.4.1 DDL 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

minimum. The DDL IN

2 Pin 2 = 24 V valves 5 Pin 5 = DDL L
3 Pin 3 = 0 V
2.4.2 DDL 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.
2.4.3 DDL 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.

2.4.4 Standards
The DDL system fulfills the standards for EMC, listed below:
W EN 61000-6-4
W EN 61000-6-2
3 Bus 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.

Bus Coupler
3.1 PROFIBUS 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.
3.1.1 Overview
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

3.1.2 Master Module
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
20 AVENTICS | 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:
9.6 / 19.2 / 93.75 / 187.5 / 500 / 1500 / 3000 / 6000 / 12000 kBaud.
PROFIBUS DP Configuration
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!

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.

English
Voltage Monitoring The applied voltage is indicated by two green LEDs. The voltages
at plug DDL are indicated. The liminal supply voltage is at
19.2 V/21.6 V for low voltage and at 26.4 V/28.8 V for
overvoltage.
Short Circuit Monitoring The bus coupler has a short circuit monitoring for the DDL. Both
power supplies are monitored independently from each other. If
the short circuit monitoring in the bus coupler starts up, the
corresponding green LED begins to flash.

Software Diagnosis In 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.

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

The limits of power supply (electronics/valves) are at 19.2 V/

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

With bus coupler 337 500 026 0 the outputs from 24 ... 31 are
