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:
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

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

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.

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 = 1 Upon 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 I/O modules and initiators connected to the DDL (with modules 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.

There has to be a terminator for the first and also for the last participant of a bus line (see illustration 8). The termination 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.

3.1.7 ATEX-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“.

3.2 DeviceNet 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.

3.2.1 Overview

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.

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.

for over voltage it is 26.4 V. The thresholds of the electronic voltage are at 19.2 for under voltage and 28.8 V for over voltage.
Short Circuit Monitoring The bus coupler has a short circuit monitoring for the DDL. Both
power supplies are observed individually from each other. If the short circuit monitoring is activated, the corresponding green LED (see Voltage Monitoring) will be flashing.

Software Diagnosis After 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.

3.2.3 Slave 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 has 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 a S5 switch. The adjustment regulations for the addressing are described in chapter 2.2 “DDL Addressing“.
DDL Mode
The DDL baud rate is adjusted with switch S6. All participants must be adjusted to the same baud rate.

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 Diagnosis The 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.

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.

3.2.7 ATEX-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“.

3.3 Interbus 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.

3.3.1 Overview

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
31.0 ... 31.7, bits 8 ... 15 in address 30.0 ... 30.7.

3.3.2 Master Module

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–AH 55
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 Interbus S failure all outputs are set at 0.
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.

The limits of the power supply (electronics/valves) are 19.2 V/
21.6 V for low voltage and at 28.8 V/26.4 V for overvoltage. The voltages are measured at plug DDL OUT. The LED DDL indicates that no communication of reference data takes place in the DDL. This can be due to:
W The adjusted baud rate of the DDL modules is not even 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
Voltage Monitoring The applied voltage supplies are indicated by two green LEDs:
The voltages at plug DDL are indicated. The thresholds of the power supply (electronic/valves) are at 19.2 V/21.6 V for under voltage and at 28.8 V/26.4 V for over voltage.
Short Circuit Monitoring The bus coupler has a short circuit monitoring for the DDL. Both
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 Diagnosis The 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–AH 63
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 and output data of the participants will not be influenced hereby.
Diagnosis data have to be requested by the highest byte of the output data field!

3.3.3 Slave 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.

Software Diagnosis The 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.

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.

3.3.7 ATEX-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“.

3.4 ControlNet 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.

3.4.1 Overview

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.

3.4.2 Master Module

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.

Input 100 24 (16 bit)
Output 150 8 (16 bit)
Configuration 4 0 (8 bit)
An electronic data sheet (EDS) is available on the internet page of the company HMS (http://www.hms-networks.com) Type: EDS Configuration File Name: AnyBus-S ControlNet
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 parameter The 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.

Software – Diagnosis After 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).

3.4.3 Slave 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 has 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 switch S5. The adjustment regulations for the addressing are described in chapter 2.2 “DDL Addressing“.

The 4 byte mode offer a conformity with 16 Bit PLC systems. Only the first 3 bytes are transferred to the outputs of the 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.
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.

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.

3.5 CANopen 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.

3.5.1 Overview

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

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.

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.

The LEDs of the DDL participants states according to the status of the initialization of the CANopen interface. Only after the bus coupler has switched to Preoperational or Operational the DDL system will be initialized and the red DDL LED may go off.
Voltage Monitoring The threshold for under voltage of the valve supply is at 21.6 V,
for over voltage it is 26.4 V. The thresholds of the electronic voltage are at 19.2 V for under voltage and 28.8 V for over voltage.
Short Circuit Monitoring The bus coupler has a short circuit monitoring for the DDL. Both
power supplies are observed individually from each other. If the short circuit monitoring is activated, the corresponding green LED (see Voltage Monitoring) will be flashing.

Software Diagnosis After 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.

3.5.3 Slave 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 has 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.

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.

The software diagnosis of the Slave module is 1 byte standard diagnosis + configured data length long. With bus coupler R412008002 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
The Slave module provides the DDL master module for CANopen 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.

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 = 1 Upon starting the system it is first determined what coils do

(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
