3. Introduction
3.1. General information
The product line DATAEAGLE 3XXX provides a transparentwireless transmission of Profibus. Xxxx stands for differentvariants which are separated by different radio technologiesand different maximum Profibus speeds on the cable side.
The data transmission is completely transparent for theProfibus master and slaves. No changes are requiredcompared to a cable connection. The radio master operateslike a Profibus slave, i.e. further cable connected Profibusslaves may be connected on the master side.
The data transmission may be installed as a point-to-pointconnection or as a radio network, i.e. one transmitter (DE-Master) and several receivers (DE-Slaves).

Fig. 3.2: Radio network
The Profibus DP bus speed is from 9600bit/s up to 1,5Mbit.Behind the transmission path the Profibus is continued withthe same speed.
Please observe the larger signal delay when using radiotransmission. The signal delay ranges approx. between20ms and 80 ms.
Using Bluetooth in a radio network with DATAEAGLE3700x with several radio receivers there is an additionalincrease of the delay.2 radio receiver with 2 DP slaves behind the link:15ms * 4 (DP slaves) * 2 (Bluetoothreceivers)= 120ms

3.3. DATAEAGLE Classic & Compact line
Dataeagle is deliverable in 2 different cases: theDATAEAGLE classic and the DATAEAGLE compact line.Both are based on the same Hard – and Software and canbe mixed. DE Compact is limited only to some types of thefamily.
The advantage of DATAEAGLE classic is the flexibility, thatmeans only in this case all radio technologies are deliverableand it has a build in Display and keys for configuration andtest. Compact line is only 1/3 of the used dimension in thecabinet.

Chapter 3 - Introduction
3.4. DATAEAGLE and Profisafe applications
At Profisafe the transmission medium is called „BlackChannel“, i.e. it is not part of the safety function. Because theDATAEAGLE acts like a cable, it does not affect the safetyfunction.
The safety functions will be executed by the Siemens F CPUand the according Profisafe modules (e.g. Siemens ET200IM 153 with input modules).
Fig. 3.2: DATAEAGLE and Profisafe
Check unconditionally if the signal delay of thetransmission path or a possible interrupt of thetransmission path (actuation of the SIL monitor) affectany safety criterias.
Practical experience has indicated that the SIL monitortime should be increased to a min. of 500ms to 800ms.
The SIL monitor time has to be set within the CPU. If thesafety function recognizes an interrupted connection path orsubscriber within this time, it switches into safe operationmode.

3.5. Delay by the radio link
The table shows the data exchange time of different devicetypes towards the Profibus subscriber behind thetransmission path at a bus speed of 500kbit/s and a DP slavewith 8Byte read/write

Chapter 4 –integrated Diagnostic Profibus slave
4. Integrated Profibus diagnostic slave
The DATAEAGLE master may be equipped with a diagnosticslave (DS). Besides the transparent transmission path theDATAEAGLE gets therefore its own DP address.
The diagnostic slave allows you to measure the transmissionpath. The software provides the Profibus master with avariable containing internal values and conditions of thetransmission path. More information can be found in chapter6.
4.1. Performance limits
Please observe the following performance limits:
The number of Profibus DP slaves is limited to 4(DATAEAGLE 3xx3) and 7 (DE 3xx2).
The number of radio receivers is limited If you use Profibus Master OP/AG/PG the dalays can
increase. Please optimise your list of transmittedvariables correspondent to the Siemens recommends
Radio links are in principle factor 1000 slower and lessrobust compared to a cable link
Ask yourself: What is the effect in the application in caseof loosing data updating for 1 second? If you expectcritical effects tell us this in your inquiry

Chapter 5 - Installation
5. Installation
5.1. Important information
Before you start with the installation please read theinformation in chapter 7 „Tips and Tricks – Improvingthe EMC safety“ and observe these during all steps ofthe installation. Thereby you avoid electromagneticinterferences and you improve the quality of the datatransmission.
Please observe during installation that DATAEAGLEmaster and slave are designed differentially. The devicesare labelled accordingly.
The DATAEAGLE master acts as a Profibus slave for thecontroller, but has not to be integrated into the Profibusnetwork. The transmission path is transparent.
The DATAEAGLE slave(s) takes control of the Profibusdevices on the other side of the transmission path.
Only when the DATAEAGLE integrated diagnostic slaveis used, this slave has to be integrated in the Profibusmaster with a GSD file.

PE has to be connected with control cabinet ground! Ifthe PE is not connected the noise filter cannot filterinterferences on 24 V DC power supply line. These maycause malfunctions, errors or the destruction of thedevice.
The nominal operating voltage of 24 V DC falls into thecategory SELV (safety extra low voltage) and is therebyno subject to the EC low voltage directive. Usage ofother power supplies is not allowed. For connection tothe 230 V AC mains supply an external wall powersupply with 12 V DC output voltage is used
CAUTION
Assembly and commissioning instructions DATAEAGLE 3000 5-6
Chapter 5 - Installation
A self-healing 0,7A fuse is integrated into the inputcircuit. This fuse cannot be exchanged. The device hasto be disconnected from the power supply for approx. 2minutes after the fuse has been triggered. Assure thatthe power supply provides 9 to 33 V DC before youswitch on the supply voltage.
After connecting the power supply the display shows forapprox. 1. sec. the message:
DE aaaa V x.yInit Medium …
aaaa = Type, e.g.. DE3703x.y = Software revision
For compatibility reasons always devices with the samehardware and software revision should be usedtogether. The hardware revision can be found on thetype plate at the rear side of the device.
Please contact Schildknecht AG for device compatibilityif hardware or software revision deviate, e.g. when theinstallation is extended.

aa = Partner adress of the other radio modembb = own station adresscc = radio channel (only for 30xx, 33xx)
As long as no Profibus subscriber is connected by cable nodata will be transmitted. The display shows the message„< - IDLE - >“.
After all previously described steps have been accomplished,if the factory settings have not been changed and a cableconnection to the DP devices has been established, themodems start to initiate a data transmission as soon as thepower supply is connected. If data is transmitted the displaysshow the following messages:
Modem 1 Modem 2
<<<<< -- >>>>> <<<<< -- >>>>>P:01 S:02 F: -- P:02 S:01 F: --
The modems are now in their initial state and you may startwith the settings or operating (see chapter 6 „Settings”).
In a radio network with several slaves, the display ofthe slaves may show occasionally the message„< - IDLE - >“. This has no impact on the datatransmission quality.

Identification numbers for 1,9 GHz DECT modules
At 1,9 GHz DECT modules the master shows the 2-linemessage:
ARI no. (12 digits)DECT no. (5 digits)
And the slave the 2-line message:
ARI no. (12 digits)Roaming change level
The ARI number (ARI = Access Right Identity) must beidentical in all master and slave modules. Only modules withidentical ARI numbers are able to communicate with eachother.
The DECT number is part of the ARI number.In a multi-master radio transmission system (two radiomasters) ARI and DECT number have to be identical in bothmasters.
Read off the ARI and DECT number at one master andwrite it down.
Call the identification number at the slaves and ifnecessary also at the second master.
Enter the ARI number at all slaves and if necessaryalso at the second master. Don’t forget the DECTnumber at the second master.
The roaming change level (2. line in slave display)defines the bit failure rate from which the slave startssearching for a new connection. Change the roamingchange level only after consultation with Schildknecht.

6.1. General information
No settings are required in the controller because thewireless data transmission is completely transparent for theProfibus master and slave.
Settings which have to be executed during commissioningare described in chapter 5.4.
Further settings and operation of the wireless transmissionsystem DATAEAGLE are described extensively and withdescription of backgrounds and correlations in the operatinginstruction “Wireless data systems DATAEAGLE DE2000and 3000”.

6.2. System stop prevention
The OB 86 indicates a module error. The OB is necessary toavoid that the controller turns into Stop condition when shortinterruptions in the Profibus communication occur.
In case of errors the inputs are typically set to zero andshould not be evaluated anymore. To save a process imageof the inputs of a Profibus slave before they are reset, thefollowing method should be applied:
Copy the inputs of a slave cyclically in an array.
When the slave fails the OB 86 will be started.
Set a flag in this OB which prevents further cyclicalcopies.
Reset the flag in the OB when the slave is back at thebus.
Eventually either OB 85 or OB 122 may be started before OB86 is started. These are called after addressing errors offailed slaves. Therefore the flag should also be set in theseOBs.

Recommendation for commissioning:
For commissioning it is recommended to select a valuebetween „010“ = 1 second and „020“ = 2 seconds. Thiseliminates an early triggering of the filter.
Afterwards the filter time may be reduced.
Recommendation for applications with Profisafe:
In applications with Profisafe the filter time should be sethigher than the SIL monitor time at Profisafe.
Please observe:The higher the filter time is selected the later as buserror is indicated (max. only as long as the selected SILmonitor time). Please verify therefore if your applicationmeets the required safety criteria with the selected filtertime.

Diagnostic data
Chapter 7 – Diagnostic slave
7. Working with the diagnostic slave
7.1. General information
The diagnostic slave is a powerful tool for monitoring thetransmission path. The diagnostic slave enables the user toperform extensive diagnostics and to visualize long termcharacteristics on the transmission path.
With its own DP slave address (see chapter 6.6.3. „Profibussettings“) an PLC can access and process diagnostic data.The PLC can be the Profibus master or any other controllerwithin the Profibus network
The provided GSD file „DE3002_D.GSD“ can be used tointegrate the diagnostic slave into the Profibus network
The diagnostic data is separated into 8 blocks of data. Eachblock has a size of 32 Byte.
The following diagnostic data is provided by theDATAEAGLE:
Block 0 General diagnostic dataBlock 1 Slave addressesBlock 2 Status of Profibus connection to the individual
DP slavesBlock 3 Response time of the (data exchange time)Block 4 Number of retried calls (timeout counter)Block 5 Number of re-starts due to errors (initializing
counter)Block 6 Number of re-starts from DP sideBlock 7 Average data rateBlock 8 Control of radioslavesBlock 9 Number of connection retries to radio slaveBlock 10 Maximal timeout of radioslavesBlock 255 Reset all counters
Assembly and commissioning instructions DATAEAGLE 3000 7-2
Chapter 6 – Diagnostic slave
7.2. Examples of applications
Application 1 - Monitor the behaviour of thetransmission path
A deterioration of the radio connection causes a lower datarate and an increase of the response time. When the radioconnection breaks down the timeout counter is increased.When the radio connection is re-established the Profibusinitializing counter is increased.
Use the data from Block 4 and 5 to monitor the characteristicof the transmission path.
Application 2 - Optimisation
With a combination of diagnostic slave and adjustment of thefilter time (see chapter 5.4.3 “Profibus settings”) you mayimprove the characteristic of the transmission path in yourapplication. This way you can reduce Profibus bus errors atthe PLC with a high filter time. By monitoring the initializingcounter you can detect even the smallest radio interruptionsbefore they are recognized by the system as a Profibus error.
For optimization use the data from Block 5.
Apllication 3 - Problems during commissioning
Sometimes it occurs that the transmission path does notoperate during commissioning. In most cases this is causedby wrong settings of the radio addresses or missing Profibusaddresses, rarely also by incompatibilities of the DP slaves.From the address list you can determine which DP slaveaddresses are listed in the DE master. The Profibusconnection status shows the condition of the Profibus statemachine in the DATAEAGLE master. With this informationwe can provide online support in case problems occur duringcommissioning.
Use the data from Block 2 and 3.

7.3. Mode of operation
The illustration shows the mode of operation in principle:
Step 1:
The PLC addresses the diagnostic slave and selects a datablock.
Step 2:
The diagnostic slave provides the selected data block.
Step 3:
The PLC reads the data block.

7.4. Integrate the diagnostic slave into aProfibus network
7.4.1. Integrate GSD file in Step 7
First the provided GSD file has to be integrated intoStep 7. Proceed with the following steps:
Copy the files DE3002_D.GSD and DE3002_D.BMPinto the directory ..\STEP7\S7TMP
Open the „Hardware configuration“
Select „Install GSD files“ in the menu „Extras“.
After successful installation you will find the DE3002diagnostic slave in the hardware catalogue under„Profibus-DP/Weitere Feldgeräte/Allgemein/DE3002-Diagnose”.
Integrate the diagnostic slave into the Profibusnetwork and assign the Profibus address which youhave set for the diagnostic slave at the DATAEAGLEmaster (see chapter 6.3.3. „Profibus settings“).
Download the hardware configuration into the DPmaster.

7.4.2. Data exchange between PLC program anddiagnostic slave
The system functions SFC14 (DPRD_DAT) and SFC15(DPWR_DAT) can be used to exchange data with thediagnostic slave.
Accessing the diagnostic slave via PLC program:
Example: Reading diagnostic data and saving in DB100starting from DBB0.
The memory address of the diagnostic slave (see hardwareconfiguration) is 256 (100hex). The error code will be savedin MW0.
CALL "DPRD_DAT"LADDR := w#16#100RET_VAL:=MW0RECORD :=P#DB100.DBX 0.0 BYTE 32
Example: Send data from DB101 starting from DBB0 to thediagnostic slave.
The memory address of the diagnostic slave (see hardwareconfiguration) is 256 (100hex). The error code will be savedin MW2.
CALL "DPWR_DAT"LADDR := w#16#100RECORD :=P#DB101.DBX 0.0 BYTE 32RET_VAL:=MW2
Controlling the diagnostic slave:
The byte 0 of the transmitting data (DB101.DBB0 in theabove example) can be used to select the diagnostic entriesof the DATAEAGLE (Display page 0 to 7).
Set DBB1 to “1” to clear the counters of the correspondingdisplay page. If you like to clear all counters call page 255.

8. Tips and Tricks
8.1. Improving the EMC safety
8.1.1. Introduction
The wireless data systems DATAEAGLE are electronicdevices which are built according to the latest state oftechnology. The ruggedly mechanical structure as well as theconstruction of the electronic components is designed forindustrial applications.
Nevertheless some measurements have to be taken duringinstallation, which are important for an error free operation. Ifthese are not observed, the measurements which have beentaken within the devices for achieving a higher interferenceresistance and surge immunity will become partly inefficient.The interference resistance of the complete system dependshighly on the correct installation, place of installation andwiring. Before installation, always check which installationinstructions are required by the supplier of the controller for asafe operation. These instructions should be consistent withthe recommendations given here.
8.1.2. Basic rules
Noise voltages which are injected by supply and signal linesinto the device as well as electrostatic voltages caused bycontact will be discharged to the grounding point. Thegrounding point has to be connected with a preferably shortcopper cable (with little resistance) to the protective earthconductor connection of the device.

Electromagneticshielding
Bus and powercables
Unusedleads
Plug housing
Mounting plate
Chapter 7 – Tips and Tricks
Use always screened cables for the interface cable and thesupply cable. Thereby you reduce the interference probabilityby a ratio of 100 compared to unshielded cables and even upto a ratio of 1000 if you also avoid loops.
The density of the shield netting should be at least 85%. Toavoid that the injected interference current on the shieldedcable becomes a source of interference itself, a connectionwith low impedance to the grounding point is very important.
Connect the shield always on both sides to EMC grounding(in general PE).
Place the bus cables at least 20 cm away from the powercables, if possible in separate cable ducts.
Connect all unused leads of a cable always on both sides toPE.
Use metallic or metallised plug housing. The shielding of thecable should always be connected to the plug housing.
Always mount all electronic devices on a galvanizedmounting plate in the control cabinet. This mounting platefunctions as EMC earth (neutral point) and is significant forthe interference suppression. That is the only way theinterference energy can flow back to the source ofinterference. Avoidcoated surfaces such as Eloxal, yellow chromated.
A sufficient discharge of the HF fields through the PE net isnot possible due to the high cable impedance. Therefore thePE net cannot be compared with EMC earth, event thoughthey are directly electrically connected.

Protective earthconductor
Control cabinetwiring
Chapter 7 – Tips and Tricks
Design all connections with EMC earth as short as possibleand as extensive as possible. Pay attention that all metallichousings have good contact to the galvanized mountingsurface.
Pay attention that all electronic or electric parts which shouldbe considered as possible source of HF interferences areinstalled in a closed metallic housing.
Run the protective earth conductors of the individual systemcomponents star-shaped towards the potential equalizationrail. Thereby you avoid that interferences are injected by PEloops which act as antennas. Unfavourable earth protectionconnections and loops may bridge EMC measurements andwill make them inefficiently.
Pay unconditional attention to a separation of N (neutralconductor) and PE (earth protection) inside the controlcabinet. Measure with a clamp-on ammeter if equalizingcurrents flow across the PE control cabinet cable. Here, nocurrents should flow permanently.

Chapter 7 – Tips and Tricks
In highly disturbed environmental conditions, which mayoccur for example in industry buildings with inductionfurnaces we recommend a PE free installation (seeillustration). The galvanized mounting plate cannot begrounded due to the high voltage drop of the differentgrounding points within the building. Because the radiomodem is only supplied with 24V DC grounding is notnecessarily requested. Only HF earth is required. If a circularcurrent across the screen is measured (measure with aclamp-on ammeter) a DC isolation should be realized byusing a X capacitor 100nF /230V. The capacitor acts with lowimpedance against high frequent interferences but avoidscircular currents.
In this installation the mounting plate may not begrounded through PE.

8.2. Guidelines for optimized installation ofantennas
Try to use directional antennas before you use omnidirectional ones. It´s a better strategy to increase the profibuscable so you can use directional antennas
Try to connect antennas and DATAEAGLE with the shortestpossible antenna cable
Do everything what is necessary to get a line-of-sidesituation between the antennas
Try to mount the antenna on a place which is free and high
The distance between two antennas which are connected tothe same modem should be 10 – 100 cm. (for DE 300x,310x)
10-100 cm
It is a good practice to have a large as possible distance toother radio systems undependent of there used frequencies.To keep 10m distance you will be on the safe side.

9. Release list of foreign devices
In general all Profibus DP slaves can be actuated wireless.
Some older Simatic S5 we find incompatibilities whichcauses in unexpected buserrors, or hanger loop of theProfibus interface in the PLC. Here only cold starts of thePLC can help.
For Simatic S7 there are no incompatibilities known.
If you connect Simatic HMI like OP or TP keep in mind thatthere is a big difference in amount of Profibus telegramswhich are generated and transferred via the radio link, whereyour data are located in the PLC. We recommend to place alltransferred data on a common block which could betransferred in one telegram via the radio. Otherwise theactualisation time will be very slow.
