Chapter 3 - Introduction
3. Introduction
3.1. General information
The product line WP-3000 provides a transparent wireless
transmission of PROFIBUS. X stands for different variants
which are separated by different maximum PROFIBUS DP
speeds on the cable side.
The data transmission is completely transparent for the
PROFIBUS DP master and slaves. No changes are required
compared to a cable connection. The radio master operates
like a PROFIBUS slave, i.e. further cable connected
PROFIBUS slaves may be connected on the master side.
The data transmission may be installed as a point-to-point
connection or as a radio network, i.e. one transmitter (WP-
3000 Master) and several receivers (WP-3000 Slaves).
Fig. 3.1: Point-to-point connection

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 with the same speed.
Please observe the larger signal delay when using radio
transmission. The signal delay ranges approx. between
20ms and 80 ms.
Using Bluetooth in a radio network with Series WP-
3000 (models 3706-X) with several radio receivers
there is an additional increase of the delay.
2 radio receiver with 2 DP slaves behind the link:
15ms * 4 (DP slaves) * 2 (Bluetooth receivers) = 120ms

Chapter 3 - Introduction
3.2. Product family
The product family WP-3000 (models 3706-X) consists of a
wide range of devices with different performance
characteristics for different radio transmission technologies.
The chart below shows the complete product range. All
products are identical in terms of structure and function, i.e.
the description for installation and settings applies to all
device types.

Chapter 3 - Introduction
3.4. ProfiSafe applications
At ProfiSafe the transmission medium is called “Black
Channel“, i.e. it is not part of the safety function. Because the
WP-3000 acts like a cable, it does not affect the safety
function.
The safety functions will be executed by the Siemens F CPU
and the according ProfiSafe modules (e.g. Siemens ET200
IM 153 with input modules).
Funkmedium= radio transmission medium
Fig. 3.2: WP-3000 and Profisafe
Check unconditionally if the signal delay of the
transmission path or a possible interrupt of the
transmission path (actuation of the SIL monitor) affect
any safety criteria.
Practical experience has indicated that the SIL monitor
time should be increased to a min. of 500ms to 800ms.
The SIL monitor time has to be set within the CPU. If the
safety function recognizes an interrupted connection path or
subscriber within this time, it switches into safe operation
mode.

Chapter 3 - Introduction
3.5. Delay by the radio link
The table shows the data exchange time of different device
types towards the PROFIBUS subscriber behind the
transmission path at a bus speed of 500kbit/s and a DP slave
with 8Byte read/write
Radio transmission

Delay typical
2.4GHz Bluetooth
3706-7, 3706-4 and 3706-1
25 ms
These time delays are caused by the device internal
PROFIBUS wireless protocol handling. From experience an
increase of the PROFIBUS speed beyond 500kbit/s does
not yield to further improvements.
This chart shows the coherence of amount of data, number
of DP slaves behind the radio link and amount of receivers to
the data exchange time for model 3706-4 @ 500kbit

MP= Multipoint

Chapter 4 –Integrated Diagnostic PROFIBUS slave
4. Integrated PROFIBUS diagnostic slave
The WP-3000 master may be equipped with a diagnostic slave
(DS). Besides the transparent transmission path the WP-3000
gets therefore its own DP address.
The diagnostic slave allows you to measure the transmission
path. The software provides the PROFIBUS master with a
variable containing internal values and conditions of the
transmission path. More information can be found in chapter
6.
4.1. Performance limits
Please observe the following performance limits:
The number of PROFIBUS DP slaves is limited to
4 (model 3706-4) and 7 (model 3706-7).
The number of radio receivers is limited
If you use PROFIBUS Master OP/AG/PG the delays
can increase. Please optimize your list of transmitted
variables correspondent to the Siemens recommends
Radio links are in principle factor 1000 slower and less
robust compared to a cable link
Ask yourself: What is the effect in the application in case
of loosing data updating for 1 second? If you expect
critical effects tell us this in your inquiry

Chapter 5 - Installation
5. Installation
5.1. Important information
Before you start with the installation please read the
information in chapter 7 “Tips and Tricks –Improving
the EMC safety”and observe these during all steps of
the installation. Thereby you avoid electromagnetic
interferences and you improve the quality of the data
transmission.
Please observe during installation that WP-3000 master
and slave are designed differentially. The devices are
labeled accordingly.
The WP-3000 master acts as a PROFIBUS slave for the
controller, but has not to be integrated into the PROFIBUS
network. The transmission path is transparent.
The WP-3000 slave(s) takes control of the PROFIBUS
devices on the other side of the transmission path.
Only when the WP-3000 integrated diagnostic slave is
used, this slave has to be integrated in the PROFIBUS
master with a GSD file.

Chapter 5 - Installation
5.2. Assembly of wireless modem
Depending on the design of the wireless modem different
assembly versions are available:
DIN-Rail assembly for
control cabinets Standard
Retaining clip (horizontal) Optional
Assembly in wall housing Optional
Complete units with assembled antennas are available for
outdoor installations.
Fig. 4.1: Wireless unit for outdoor installation
Fasten the modems at the designated spots according to
their kind of assembly.
If there is no control cabinet available we recommend
installation in a wall mounted cabinet (available under
part number 10578 –dimensions: 380x190x130)

Chapter 5 - Installation
5.3. Antenna assembly
Connect the antenna cable with the antenna
connection of the modem.
Fasten the antenna at the according locations.
Please pay attention to the guidelines about optimal
antenna assembly as described in chapter 8 “Tips and
Tricks”.

Chapter 5 - Installation
5.4. Electrical connection
Connect the modems to the power supply according to
the pin configuration as shown below. You may use the
24V supply of the control cabinet.

24V DC gate input
PE has to be connected with control cabinet ground! If
the PE is not connected the noise filter cannot filter
interferences on 24 V DC power supply line. These may
cause malfunctions, errors or the destruction of the
device.
CAUTION
The nominal operating voltage of 24 V DC falls into the
category SELV (safety extra low voltage) and is thereby
no subject to the EC low voltage directive. Usage of
other power supplies is not allowed. For connection to
the 230 V AC mains supply an external wall power
supply with 12 V DC output voltage is used

Chapter 5 - Installation
Aself-healing 0,7A fuse is integrated into the input
circuit. This fuse cannot be exchanged. The device has
to be disconnected from the power supply for approx. 2
minutes after the fuse has been triggered. Assure that
the power supply provides 9 to 33 V DC before you
switch on the supply voltage.
After connecting the power supply the display shows for
approx. 1 sec. the message:
DE aaaa V x.y
Init Medium…
aaaa
=
Type, e.g. DE3703
x.y

Software revision
For compatibility reasons always devices with the same
hardware and software revision should be used
together. The hardware revision can be found on the
type plate at the rear side of the device.
Please contact Schildknecht AG for device compatibility
if hardware or software revision deviate, e.g. when the
installation is extended.

Chapter 5 - Installation
Afterwards the display shows the message
<- IDLE - > or
<<<<< - - >>>>>
P:aa S:bb F: cc P:aa S:bb F: cc
aa = Partner address of the other radio modem
bb = own station address
cc = radio channel (only for 30xx, 33xx)
As long as no PROFIBUS subscriber is connected by cable
no data 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 cable
connection to the DP devices has been established, the
modems start to initiate a data transmission as soon as the
power supply is connected. If data is transmitted the displays
show 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 start
with the settings or operating (see chapter 6 “Settings”).
In a radio network with several slaves, the display of
the slaves may show occasionally the message
“< - IDLE - >”. This has no impact on the data
transmission quality.
