3 Brief description
Wireless communication is based on Trusted Wireless 2.0 technology. The high require-
ments for interference-free data transmission are met in particular through the use of the
FHSS (frequency-hopping spread spectrum) method and 128-bit data encryption (AES).
The SATEL-LP24 wireless module uses the license-free 2.4 GHz ISM band.
The SATEL-LP8 wireless module uses the 868 MHz ISM band, which is license-free in
Europe.
3.1 Wireless modules
In addition to an RS-232 and RS-485 2-wire interface, the SATEL-LP24 and SATEL-LP8
wireless modules support the option of directly connecting up to 32 I/O extension modules
in the station structure via the DIN rail connector.
Addressing of the wireless module and I/O mapping of the I/O extension modules is carried
out quickly and easily by means of the thumbwheel on the front. You can use the yellow
thumbwheel on the wireless module to set the RAD ID and the white thumbwheel on the ex-
tension modules to set the I/O MAP address. Programming knowledge is not required. You
can easily start up the wireless network without the need for software.
The SATEL-LP-CONF configuration and diagnostics software for special functions and di-
agnostics options of the wireless module is available free of charge.
Features
– Flexible network applications: I/O data, serial data, PLC/Modbus RTU mode
– Adjustable data rates for the wireless interface
– Easy point-to-point or network structures (star, mesh)
– Yellow thumbwheel for unique addressing of wireless modules in the wireless network
– Integrated RS-232 and RS-485 interface
– Can be extended with up to 32 I/O modules per station via DIN rail connector (hot-
swappable)
– 128-bit AES data encryption and authentication
– Unique network addressing via plug-in configuration memory (SATEL-LP-CONF stick)
for secure, parallel operation of multiple networks with different RF bands
– Data rates and ranges can be configured using the SATEL-LP-CONF software
– International approvals

4.3 Mounting/removal
You can connect up to 32 different I/O extension modules to each wireless module via the
DIN rail connector. Data is transmitted and power is supplied to the I/O extension modules
via the bus foot.
When using the device in a connection station, use the supplied 17.5 mm DIN rail connec-
tor. Only use the DIN rail connector in conjunction with 24 V DC devices.
Figure 4-3 SATEL-LP connection station with up to 32 I/O extension modules
– Mount the wireless module to the left and the I/O extension modules only to the right
of the wireless module.
– The individual extension modules can be arranged in any order.
– SATEL-LP24 wireless module only: install the wireless module at least one meter
away from other devices using the 2.4 GHz frequency band (e.g., WLAN, Bluetooth,
microwave ovens). Otherwise, both the link quality and the data transmission speed
will be reduced.

Figure 4-4 Assembly and removal
To mount a connection station with DIN rail connectors, proceed as follows:
• To form a connection station, connect the DIN rail connectors together.
• Push the connected DIN rail connectors onto the DIN rail.
• Place the device onto the DIN rail from above (see Figure 4-4, D). Make sure that the
device and DIN rail connector are aligned correctly.
• Holding the device by the housing cover, carefully push the device towards the mount-
ing surface so that the device bus connector is fixed securely on the DIN rail connector.
• Once the snap-on foot snaps onto the DIN rail, check that it is fixed securely. The device
is only mechanically secured via the DIN rail.
• Connect the desired number of I/O extension modules to the wireless module via the
DIN rail connector.
• Install the device in suitable housing to meet the requirements for the protection class.
• During startup, check that the device is operating, wired, and marked correctly.
Removal
• Use a suitable screwdriver to release the locking mechanism on the snap-on foot of the
device (see Figure 4-4, E).
• Hold onto the device by the housing cover and carefully tilt it upwards.
• Carefully lift the device off the DIN rail connector and the DIN rail.

• Insert the wire with ferrule into the corresponding connection terminal block.
• Use a screwdriver to tighten the screw in the opening above the connection terminal
block. Tightening torque: 0.6 Nm.
4.5 Connecting the power supply
Connect a DC voltage source (19.2 V ... 30.5 V DC) to the wireless module. The nominal
voltage is 24 V DC. Supply voltage to the device via terminal blocks 1.1 (24V) and 1.2(0V).
In the case of a connection station, it is sufficient to supply the first device in the group.
Figure 4-6 Connecting the power supply
In order to prevent damage to the wireless module, we recommend installing a surge pro-
tective device. Make sure the wiring between the surge protective device and the wireless
module is as short as possible. Please also observe the manufacturer’s specifications.
For easy installation, it is also possible to pull the screw terminal block out of the device
and to re-insert it after having connected the cables.

4.6 Serial interfaces
The wireless modules have one RS-232 interface and one RS-485 2-wire interface. Con-
nect the I/O device to the wireless module via the corresponding interface.
4.6.1 Shielding of the RS-485 bus line
• Connect the shield of the RS-485 bus line correctly via an external shield terminal (e.g.
SKS 8-SNS35, Order No. 3062786).
Choose the type of shield connection according to the expected interference:
– Firstly, connect the shield on one side. This suppresses electrical fields.
– To suppress disturbances caused by alternating magnetic fields, connect the shield on
both sides. When doing so, ground loops must be taken into consideration. Galvanic
disturbances along the reference potential can interfere with the useful signal, and the
shielding effect is reduced.
– If several devices are connected to a single bus, the shield must be connected to each
device (e.g., by means of clamps).
– Connect the bus shield to a central PE point using short, low-impedance connections
with a large surface area (e.g., by means of shield terminals).
– Activate and configure the RS-232 or RS-485 interface using the SATEL-LP-CONF
software (from page 38).
– You can only use one interface per wireless module. Parallel operation of both inter-
faces is not possible.
NOTE: Damage to the interface
If the shield has been connected incorrectly, permanent, external disturbing pulses may
damage the interface.
Observe the polarity of the RS-485 2-wire cable and make sure that the shield is connect-
ed correctly.

4.6.2 Terminating the RS-485 bus line
The wireless modules are operated on a 2-wire bus line. RS-485 bus connections must be
terminated at both ends with a 390/150/390 termination network.
• Depending on the position of the device on the RS-485 bus line, the termination net-
work must be activated or deactivated.

4.6.3 RS-485 pin assignment
In RS-485 mode, you can create a network with several I/O devices. Use a twisted pair bus
line to connect the I/O devices. Fit this bus line with a termination network at the two furthest
points.
• Connect the single wires of the data cable to the COMBICON plug-in screw terminal
block (Figure 4-1, item 10).
• Make sure the signal assignment is correct.
Figure 4-8 RS-485 interface pin assignment
4.6.4 RS-232 pin assignment
In RS-232 mode, point-to-point connections can be established.
According to the standard, you can connect a DCE device (Data Communication Equip-
ment) to the RS-232 interface using a 1:1 cable (Figure 4-9). It is also possible to connect a
DTE device using a crossed cable (Figure 4-10).
Figure 4-9 RS-232 interface pin assignment (DTE - DCE)
Figure 4-10 RS-232 interface pin assignment (DTE - DTE)
If you are not sure whether the device to be connected is of DTE or DCE type, you can also
measure the voltage. Measure the voltage between Tx and GND in the idle state:
– If the voltage measures approximately -5 V, it is a DTE device.
– If the voltage measures approximately 0 V, it is a DCE device.
– The RS-232 interface of the wireless module is of DTE type (Data Terminal Equip-
ment). This means that terminal point 5.2 (Tx) is always used to transmit and terminal
point 5.1 (Rx) is always used to receive.
– Only connect the wireless module to devices which meet the requirements of
EN 60950.

4.7 Connecting the antenna
The wireless module has an RSMA antenna socket for an external antenna. Various instal-
lation examples can be found under “Typical combinations of antennas and adapter cables”
on page 149.
Figure 4-11 Connecting the antenna
– Install the antenna outside the control cabinet or building.
– Please also observe the installation instructions for the antenna as well as Section
“For your safety” on page 17.

5.2 Operating mode of the wireless module
The SATEL-LP wireless system offers three different options for signal and data transmis-
sion:
If the wireless system is operated in an environment where other networks are also present,
e.g., additional SATEL-LP networks, then a configuration memory can be used (see “Con-
figuration via SATEL-LP-CONF stick” on page 35). Extended settings of the wireless mod-
ules can also be configured using the SATEL-LP-CONF software (from page 38).
5.2.1 I/O data mode
Figure 5-1 I/O data mode
By default upon delivery, all wireless modules are in I/O data mode. For simple I/O-to-I/O
applications with extension modules, you can easily set the addresses using the thumb-
wheel. You can therefore establish a wireless connection to other wireless modules without
any programming effort (see “Setting the address of the wireless module using the thumb-
wheel” on page 35 and “Setting the address of the extension modules using the thumb-
wheel” on page 53).

In serial data mode, multiple controllers or serial I/O devices are networked quickly and eas-
ily using wireless technology. In this way, serial RS-232 or RS-485 cables can be replaced.
You need to configure each wireless module using the SATEL-LP-CONF software (from
page 38).
5.2.3 PLC/Modbus RTU mode
Figure 5-3 PLC/Modbus RTU mode
You can connect the I/O extension modules to the controller directly via the integrated
RS-232 and RS-485 interface by means of wireless communication. In PLC/Modbus RTU
mode, the master wireless module (RAD ID = 01) operates as a Modbus slave. The master
wireless module has its own Modbus address.
You can connect extension modules to each wireless module in the network. The I/O data
of the extension module is stored in the internal Modbus memory map of the master wireless
module. In addition, the diagnostic data from all wireless devices is stored here.
You need to configure each wireless module using the SATEL-LP-CONF software (from
page 38).

5.3 Setting the address of the wireless module using
the thumbwheel
• Start by setting the desired station address with the yellow thumbwheel on the wireless
module. There must be one master (RAD ID = 01) and at least one repeater/slave
(RAD ID = 02 ... 99) in a network.
The following settings can be made using the yellow thumbwheel:
5.4 Configuration via SATEL-LP-CONF stick
By default upon delivery, all wireless modules have the same network ID and the same
RF band. Using a configuration memory (SATEL-LP-CONF stick), you can configure a
unique and secure network without the need for software.
The SATEL-LP-CONF stick is used as a network key. Its network address (network ID) is
unique and cannot be assigned via the SATEL-LP-CONF software. Only wireless modules
with the same network ID can connect to one another.
You must configure each individual network device. Just one SATEL-LP-CONF stick is
needed for all the wireless modules in the network. After configuration, you can remove the
SATEL-LP-CONF stick from the wireless module.
The SATEL-LP-CONF stick also contains a preset frequency band (RF band). An RF band
is a group of frequencies made up of individual frequencies from the entire frequency band.
Different RF bands use different frequencies.
– The addressing in a network must be unique. If two wireless modules in a network
have the same address, the network will not function correctly.
– Setting the address via the thumbwheel has priority over setting the address via the
SATEL-LP-CONF software.
– After making any change to the module address, press the SET button for one sec-
ond to apply the setting.

If you operate several SATEL-LP wireless systems in parallel, you should select different
RF bands.
Different SATEL-LP-CONF sticks are available for easy configuration without the need for
software:
For SATEL-LP24:
– SATEL-LP-CONF3 for RF band 3 (Order No. YO0003, yellow)
– SATEL-LP-CONF5 for RF band 5 (Order No. YO0005, green)
– SATEL-LP-CONF7 for RF band 7 (Order No. YO0007, blue)
For SATEL-LP8:
– SATEL-LP8-CONF1 for RF band 1 (Order YO0001, red)
Figure 5-4 Configuration via SATEL-LP-CONF stick
• Carefully insert the SATEL-LP-CONF stick with the 12-pos. IFS connector into the
S-PORT of the wireless module.
• Press the SET button on the wireless module for one second. Parameter read-in is
started. Read-in has been completed when the DAT LED lights up once. The new pa-
rameters are activated.
• Remove the SATEL-LP-CONF stick from the wireless module.
• Repeat this process for each individual wireless module in the network.
SATEL-LP24: you can also set different RF bands from 1 ... 8 and network IDs from
1 ... 127 using the SATEL-LP-CONF software (see page 39).
SATEL-LP8: for additional information on the various RF bands in 868 MHz wireless sys-
tems, refer to “RF bands” on page 124.

5.5.1 Saving parameters from the wireless module to the
memory stick
Copy common network parameters and individual device parameters to the memory stick:
• Press and hold down the SET button on the wireless module for at least six seconds.
• The four RSSI bar graph LEDs start a running light from bottom to top.
• Insert the memory stick in the S-PORT of the wireless module. The copying of param-
eters is started automatically.
• Wait until the running light stops. The write process has been completed.
• Remove the memory stick from the wireless module.
– Pay attention to the firmware version of the wireless modules before using the mem-
ory stick. In order to ensure that a wireless module is capable of reading the memory
stick, it must have the same or later firmware version as the wireless module whose
configuration file is to be copied. Wireless modules with an earlier firmware version
are not able to read the memory stick.
– If an error is detected while saving or checking the data, the DAT and ERR LEDs flash
simultaneously.

5.6.1 Extended configuration, individual settings
After reading in an existing network project or creating a new project, the network settings
can be modified under “Individual Settings”. Here, the wireless network can be optimized
and adapted to your specific requirements. When you move the mouse over the individual
network parameters, you will see a short description under “Help”.
Figure 5-5 SATEL-LP-CONF software: Network Settings
5.6.2 Transmission power
Observe the maximum permissible radiated transmission power at the antenna (EIRP, see
Table 5-4 or Table 5-5). If necessary, reduce the device transmission power via the
SATEL-LP-CONF software.
The transmission power can be calculated as follows:
Device transmission power + Antenna gain - Cable attenuation
If several wireless systems are operated in parallel and in close proximity, you must set
the RF band and the network ID. These parameters can be set via the SATEL-LP-CONF
software or by using a SATEL-LP-CONF stick (see “Configuration via SATEL-LP-CONF
stick” on page 35).

5.6.3 Data transmission speed of the wireless interface
The range is an important parameter in industrial wireless applications, especially in out-
door applications. Even in cases where long ranges do not have to be covered, good re-
ceiver sensitivity enables transmission in harsh outdoor conditions, e.g., when there is no
direct line of sight.
The receiver sensitivity determines the signal amplitude which can just about be received
by the wireless module. The lower the data transmission speed of the wireless interface, the
higher the receiver sensitivity and therefore the range.
You can cover distances in the kilometer range using the wireless module if the following
conditions are met:
– Suitable gain antennas are used
– Line of sight
– Adherence to the Fresnel zone
If you reduce the data transmission speed, obstacles such as walls or trees can be over-
come much better. Please note, however, that the delay time increases when the data rate
is reduced.
Adjust the data transmission speed of the wireless interface to the respective application
using the SATEL-LP-CONF software (SATEL-LP24 default setting = 125 kbps,
SATEL-LP8 default setting = 9.6 kbps).

5.6.4 Device settings
You can assign a device name or set the transmission power under “Device Settings”. All
device parameters are listed on the “Overview” tab.
Figure 5-8 SATEL-LP-CONF software: Individual Settings, Overview
By default upon delivery, the receive preamplifier is activated and the transmission power
is set so that the devices can cover the greatest possible distances (SATEL-LP24:
18 dBm, SATEL-LP8: 27 dBm). Therefore, if the devices are operated directly next to one
another the receiver may become overloaded. In this case, remove the antennas, in-
crease the distance between the devices and antennas or reduce the transmission power
using the SATEL-LP-CONF software.
Configuration and startup
106983_en_01 SATEL 43
Depending on the operating mode, you can configure the serial interface under “Individual
Settings” on the “Serial Port” tab.
To activate the serial interface, select the “Serial data” or “PLC/Modbus RTU mode” network
application under “Network Settings”.
Figure 5-9 SATEL-LP-CONF software: Individual Settings, Serial Port
Under “Individual Settings” on the “Allowed Parents” tab, you can define the wireless mod-
ules to which a connection may be established. This setting is required, for example, when
creating repeater chains. Repeater chains are used to circumvent obstacles or to set up re-
dundant wireless paths by means of several repeaters.
Figure 5-10 SATEL-LP-CONF software: Individual Settings, Allowed Parents
You can only use one interface per wireless module. Parallel operation of both interfaces
is not possible.
The “Allowed Parents” tab is only available if the “Line/Mesh” network type has been se-
lected.

TX LED, transmit data
The green TX LED indicates communication on the RS-232/RS-485 interface. The wireless
module is transmitting data.
In I/O data mode, the TX LED on the wireless master flashes (RAD ID = 01). This indicates
that the wireless master is continuously sending search requests to RS-485 stations.
RX LED, receive data
The green RX LED indicates communication on the RS-232/RS-485 interface. The wireless
module is receiving data.
SET button
You can confirm a station change with the SET button, without having to perform a power
up. Station changes include:
– Changing the RAD ID address of the wireless module
– Changing the I/O MAP address of the extension module
– Adding or removing an I/O extension module
– Using a SATEL-LP-CONF stick or memory stick
After making any change, press the SET button for at least one second to apply the settings.
The DAT LED starts flashing. The read-in process has been completed once the DAT LED
stops flashing.
RF link relay
The RF link relay in the wireless module diagnoses the state of the wireless connection. If
the device is no longer receiving the data packets correctly, the relay is deactivated after a
while. The relay picks up again automatically when the wireless connection is re-estab-
lished. The relay has been designed as a change-over contact.
RSSI test socket
A voltage measuring device can be connected to the RSSI test socket (2.1/2.2) to measure
the RSSI voltage from 0 V ... 3 V. You can use the table on page 46 to determine the re-
ceived signal strength based on the measured voltage. However, please note the small volt-
age fluctuation due to multipath propagation.
The RSSI voltage depends on the data rate set for the wireless interface. The higher the
RSSI voltage, the better the wireless connection.
For example, the RSSI voltage may be helpful when positioning and aligning the antenna.
The recommended minimum signal strength is 1.5 V DC. This results in a power reserve of
around 10 dB, which ensures communication even in unfavorable transmission conditions.
The RF link relay can be used as a fault message contact to indicate the failure of the wire-
less connection to the controller.

RSSI LED bar graph
Figure 5-12 Bar graph for point-to-point connection
In a point-to-point connection with just two wireless modules, the LED bar graph is active on
both the master and the repeater/slave.
Figure 5-13 Bar graph for point-to-multipoint connection
In a wireless network with more than one repeater/slave, only the yellow LED on the master
is permanently on. The signal strength is displayed on the repeaters/slaves. The indicated
signal strength is always related to the next wireless module in the direction of the master
(parents).
You can read the RSSI values via the serial interface of the master wireless module using
Modbus/RTU commands (see Section “RSSI signal and error code registers” on page 78).

Several corresponding output modules at different stations can be assigned to one digital
or analog input module. The inputs are transmitted parallel to all the outputs. The channels
of the input module are mirrored to the channels of the output module.

The combined SATEL-LP-DAIO6 extension modules can only be assigned in pairs, be-
cause each module has inputs and outputs. That is why only two modules in the network
may have the same I/O MAP address.

5.9.2 Setting the address of the extension modules using the
thumbwheel
For I/O-to-I/O transmission of signals, you must assign a corresponding output module to
the input module. Set the I/O MAP address (01 ... 99) using the white thumbwheel on the
I/O extension module.
Addressing extension modules
• Use the thumbwheel to set the address.
• Press the SET button on the front of the wireless module to read the active configura-
tion.
The following settings can be made using the white thumbwheel:
The following conditions must be met:
– Addresses 1 ... 99 (maximum) can be assigned for the extension modules in the entire
wireless network.

Wireless module in I/O data mode
– The input module must be provided with the same I/O MAP address as the assigned
output module at another station (I/O mapping). Output modules with the same I/O MAP
address may appear several times in the network at different stations.
– The I/O MAP address of an input module may only appear once in the network.
– The channels of the input module are directly assigned to the channels of the output
module:
Wireless module in PLC/Modbus RTU mode
–Output modules must not have the same I/O MAP address as input modules. Excep-
tion: output modules with the same I/O MAP address may appear several times in the
network at different stations.
– The I/O MAP address of an input module may only appear once in the network.
– The input and output data is saved in a Modbus memory map in the master wireless
module. You can read or write the process data via the serial interface of the master
wireless module (RAD ID = 01) using the Modbus/RTU command. The process data ta-
bles can be found starting on page 64.
5.10 Startup time of the wireless station
Once a wireless station has been started up (power “ON”), the wireless module will take
several seconds until it is ready for operation. Each connected I/O extension module in-
creases the startup time. Accordingly, a complete wireless station with 32 I/O extension
modules may take several minutes to start up. Only after this time has elapsed is the wire-
less station ready for operation.
Input module Output module
Channel 1 Channel 1
Channel 2 Channel 2

It is not possible to individually assign the channels of the input and output modules.
Serial data mode
106983_en_01 SATEL 55
6 Serial data mode
In serial data mode, multiple controllers or serial I/O devices are networked quickly and eas-
ily using wireless technology. In this way, serial RS-232 or RS-485 cables can be replaced.
Figure 6-1 Serial data mode
You can configure the serial interface of the wireless module using the SATEL-LP-CONF
software. In order to connect the wireless module to the PC, you need the SATEL-LP-PROG
USB cable (Order No. YC0520).
– When operating the network in serial data mode, it may not be possible to diagnose
all devices. In this case, stop the serial application in order to perform full diagnostics.
– Using the SATEL-LP-CONF software, you can assign different serial settings to the
devices under “Individual Settings”.
– For additional information on the USB cable, please refer to the package slip of
SATEL-LP-PROG. The latest documentation can be downloaded via the product at

6.1 Frame-based data transmission
T
IdleMin
parameter (minimum pause between two frames)
The T
IdleMin
parameter refers to the minimum pause that must elapse between two frames
on the output side (wireless module is transmitting data via the serial interface).
Figure 6-4 Frame-based data transmission: T
IdleMin
parameter
T
FrameEnd
parameter
T
FrameEnd
is the time maintained by the transmitting wireless module between two frames.
If the data received by the wireless module is followed by a certain period of time where no
further data is received, the wireless module assumes that the frame has arrived in its en-
tirety. The frame is then transmitted. This period of time is referred to as T
FrameEnd
.
T
FrameEnd
must be shorter than the minimum interval between two frames
(T
FrameEnd
<T
IdleMin
). T
FrameEnd
must, however, also be greater than the maximum interval
that is permitted between two characters in a frame. Otherwise the frame might be frag-
mented.

Setting telegram pauses based on the example of Modbus/RTU
A frame is also referred to as a telegram. The length of the transmission pause between the
telegrams depends on the set data rate. The beginning and end of a telegram is recognized
by means of a time condition. A pause of 3.5 characters means that the telegram is com-
plete and the next character is to be interpreted as the slave address. A telegram must
therefore be sent as a continuous stream of data. If there is an interruption of more than
1.5 characters within a telegram, the data will be discarded by the receiver.
If the master is not able to transmit the successive characters quickly enough and commu-
nication is aborted, you must increase the minimum pause time (T
FrameEnd
) between the in-
dividual characters of a telegram.
• To adapt data transmission to other protocols, you can adjust the T
FrameEnd
and T
IdleMin
parameters accordingly. Set the interface parameters under “Individual Settings”.

106983_en_01 SATEL 59
7PLC/Modbus RTU mode
Activate PLC/Modbus RTU mode using the SATEL-LP-CONF software (from page 38). In
PLC/Modbus RTU mode, you can wirelessly connect I/O extension modules directly to a
controller (I/O to serial). The wireless module provides an RS-232 or RS-485 interface for
this. In PLC/Modbus RTU mode, the master wireless module works as a Modbus slave and
has its own Modbus slave address. The entire wireless network therefore behaves like a
single Modbus slave.
You can connect I/O extension modules to each wireless device in the network. A wireless
network can have a maximum of 99 extension modules. Use the white thumbwheel to set
the I/O MAP addresses.

• Select PLC/Modbus RTU mode and assign a Modbus address.
• Follow the software wizard.
In order to enable the master wireless module to communicate with a controller via the
RS-232 or RS-485 interface, you must set the interface parameters. Please note that the
controller settings must match the settings of the wireless module.
The Modbus connection between the controller and the wireless module can be monitored
via a watchdog.
7.2 Addressing I/O extension modules
In PLC/Modbus RTU mode, a wireless network can have a maximum of 99 I/O extension
modules.
• Use the white thumbwheel on the I/O extension module to set the I/O MAP address.
You can find information on addressing extension modules on page 53 onwards.
The Modbus address is a unique address in the Modbus network. It is only assigned for
the master wireless module (RAD ID = 01). You can assign an address between
1 and 247.

7.3 Watchdog
The Modbus telegram watchdog monitors the connection between the master wireless
module and the controller. It is triggered each time a Modbus telegram is received correctly.
You can activate the watchdog using the SATEL-LP-CONF software.
• Under “Individual Settings”, select the “Network Settings” item. You can set a watchdog
time of 200 ms ... 65000 ms here.
.
Figure 7-3 SATEL-LP-CONF software: Individual Settings, Network Settings
When the watchdog is triggered, an action will be performed on the I/O output modules. You
can set the behavior in the event of an error using the DIP switches on the front:
– OFF = RESET: the output value is set to 0
– ON = HOLD: hold the last output value
For more information about setting the DIP switches for the different extension modules,
please refer to Section “Description of I/O extension modules” on page 81.
If the watchdog is activated and Modbus communication is interrupted, the red ERR LED
will flash on all wireless modules in the network. Depending on the DIP switch settings, the
output modules output the corresponding hold or reset value.

You must enter 0000 (hex0000) as the start address in order to read register 30001. The
address area 3xxxx is already defined by the function code field.
Function codes 03 and 16
You must enter 0031 (hex001F) as the start address in order to read or write register
40032 ... 40039. The address area 4xxxx is already defined by the function code field.
Table 7-2 Supported Modbus function codes

– Other function codes exist in the Modbus protocol, but they are not supported.
– Registers 1 ... 123 can be read or written with a command.
Please note that a distinction is made in the Modbus telegram between the register num-
ber and register address:
– The register number starts with 1.
– The register address starts with 0.

7.5 Module type and error code registers for I/O exten-
sion modules
You can read the module type and data currentness of the I/O extension modules from reg-
isters 30xx0 and 40xx0.
The individual I/O extension modules can be clearly distinguished by the module type. The
module type ID of the extension module can be read in the Modbus register.
Table 7-4 Module type IDs
“Module type” register value
If the module type in the register is invalid or unavailable, then the register value is 0.
“Currentness of data” register value
If the data in the register is not up to date, then the register value is 1. This is the case, for
example, if the wireless connection to an input module fails. The IN process data is then re-
tained in the Modbus table, but is no longer updated. In the case of an output module, the
“Currentness of data” register value is set to 1 until the OUT process data has been written
to the Modbus registers. The read I/O data is only valid and current if a valid module type
value is returned by the slave and the “Currentness of data” register value is 0.

7.5.1 Assigning I/O extension modules to the register
You can use the white thumbwheel on the I/O extension module to assign an I/O MAP ad-
dress in the Modbus memory map. Example: if you set the thumbwheel of an input module
to I/O MAP address = 01, the register assignment is 30010.
7.6 Modbus memory map
The I/O data from the extension modules is stored in an internal register, the Modbus mem-
ory map. The Modbus memory map is located in the master wireless module with
RAD ID = 01. The data contained here can be read or written by a Modbus master.
The following process data tables for the individual extension modules show at what point
the I/O data is stored in the Modbus memory map. You can find a complete overview of the
Modbus memory map on page 75 onwards.
The RSSI signal register can be found on page 78 onwards.

7.6.10 RSSI signal and error code registers
The RSSI values indicate the received signal strength on the wireless module. You can read
the RSSI values via the serial interface of the master wireless module (RAD ID = 01) using
Modbus/RTU commands. The RSSI values of all wireless modules in the network are within
address area 35001 ... 35250.
Bit 08 = error on IFS bus
If an error is present on the IFS bus, the register value is 1 (e.g., local bus error, because the
input or output module is disconnected from the DIN rail connector). If no error is present on
the IFS bus, the register value is 0.
– Bits 9 ... 15 are reserved.

8.1.3 Setting the DIP switches
You can configure the input signals using the DIP switches on the front (0 mA ... 20 mA or
4 mA ... 20 mA). Any changes to the DIP switch settings will be applied immediately. In
PLC/Modbus RTU mode, the setting of the input signals is evaluated for error diagnostics.
When set to 4 mA ... 20 mA, for example, it is possible to detect an open circuit.

8.2 SATEL-LP-PT100 – extension module with four
temperature inputs
The SATEL-LP-PT100 analog I/O extension module has four Pt 100 inputs for temperatures
from -50°C ... +250°C. Pt 100 inputs T1 ... T4 can be mapped to analog outputs
I1/U1 ... I4/U4 of the SATEL-LP-AO4 extension module. All inputs are electrically isolated
from one another, from the supply voltage, and from the remaining electronics.
Pt 100 resistance thermometers can be connected to the SATEL-LP-PT100 I/O extension
module. The thermometers change their resistance according to the temperature. The
Pt 100 input signals are acquired by the SATEL-LP-PT100 and can be mapped to propor-
tional, analog voltage or current signals of the SATEL-LP-AO4 output module.
Example: at a temperature of -50°C at the Pt 100 input, a current of 0 mA or a voltage of 0 V
is output at the output module. At a temperature of 250°C at the Pt 100 input, a current of
20 mA or a voltage of 10 V is output.
