Product description
General product description
In connection with a base module alpha WSN BM 1x0, the sensor module
alpha WSN SM 230 forms a universal wireless network for the sensor data
acquisition. If required, repeaters (alpha WSN RM 300 or alpha WSN RM 300-G) can
be used for the extension of the range.
The sensor module alpha WSN SM 230 has different interfaces for the connection of
many different sensors or signals and may also be used as repeater module itself.
Recorded measured values are cyclically transmitted to the base module by radio.
This base module is linked with a PC or IP network by means of different interfaces,
depending on the type of base module.
For displaying the measured values and events and the setting of the parameters the
sensor modules, the PC software alpha data view is available.

Product description
The sensor data acquisition is often connected with much installation work (laying of a
multitude of cables in areas that are often impracticable and separated) and / or high
personnel expenditure (manual reading of single sensors, interpretation of the measur-
ing results regarding exceeding of the limit etc.). In both cases, considerable financial
expenses arise.
A reasonably priced, flexible alternative that can be adapted to special requirements is
the sensor network alpha WSN from FMN.
Depending on the measuring interval, a total of up to several hundred measuring points is
possible. In order to be able to achieve a sufficient coverage or a higher range, repeaters
can be used. They extend the range of the wireless measurement system by far.
Modules of the wireless measurement system
Base module
The base module receives the transmitted data of the sensor modules and transfers
these over a RS232, USB, LAN or WLAN interface to a PC or an IP network.
The RS232 interface is available at all module versions.
The LAN or WLAN interfaces make the connection to an Intranet or to the Internet
possible and therewith the worldwide inquiry of the measurement data.
At the combination LAN / RS232 (alpha WSN BM 110), the voltage supply will be realized
over an external pluggable power supply unit or over the LAN connection (PoE – Power
over Ethernet) if an appropriate PoE voltage supply is installed in the LAN.
At the combination USB / RS232 (alpha WSN BM 120), it is possible to realize the voltage
supply over the USB interface. Alternatively, the voltage supply can also be realized
over a power supply unit.
At the combination WLAN / RS232 (alpha WSN BM 130), the voltage supply has to be
realized over an external power supply unit.
Sensor module
The sensor module is for the connection of different sensors.
The acquired data is transmitted to the base module by radio and from there, it is
transferred to a PC.
An inquiry as well as setting of the parameters of the sensor modules from base module
(polling) is also possible.
The voltage supply is realised over an internal 3.6 V battery (lithiumthionylchloride,
size 2/3 A). In case the battery voltage is falling below the minimum battery voltage, a
message is sent to the base station. The battery should be changed then. An intelligent
power management guarantees a long battery lifetime.

Description of device-specific features
Repeater module
The repeater module is for the transmission of the sensor data to the base module. It is
used in case of difficult radio propagation conditions or in case the distances between
sensor and base module are too great.
The voltage supply is realized via an external power supply unit.
A voltage supply over an internal 3.6 V battery (lithiumthionylchloride, size LR14) is
possible, but it is not recommended because of the higher power demand of the re-
peater module.
All versions of the repeater module alpha WSN RM 300 can be used. But a configuration
of the sensor module alpha WSN SM 230 to repeater operation is also possible.
Description of device-specific features
Base modules
The base modules of the sensor network are the interface to the PC network or the IP
network. They receive the data of the single sensor modules and transfer them to a PC.
Connections over RS232, USB, LAN or WLAN are available for this.
The base module can temporarily store up to approx. 45,000 sensor data sets. In case of a
temporary termination of the visualization software or switching off of the PC, the sensor
data is so buffered and is not lost. After starting the visualization software again, the
data is transmitted to the PC.
Furthermore, the base module is equipped with two potential-free outputs (change-over
contacts) that can be controlled from the PC, if required (alarm signalling).
There are two LEDs at every base module. The green LED indicates the operation of the
module (glowing when the module is active) and the red LED indicates correctly trans-
mitted and received packets of data.
Status LED (red) glowing for approx. 50 ms: packet of data transmitted correctly
Status LED (red) glowing for approx. 500 ms: packet of data received correctly

All base modules have a standardised socket board with potential-free outputs. These
can e. g. be used as alarm outputs. The control is realized over the visualization software
alpha data view. This interprets the received data and sends a command for the activa-
tion of the alarm outputs to the base module, if required. Following, the Pin assignment

Description of device-specific features
Sensor module
Different sensors can be connected to the sensor module SM 230. Two 16-pole terminal
strips are available for this.
Sensor cables with a cross section of 0.08 - 0.5 mm2 (AWG 28-20) can be connected.
The cable terminations should be stripped 5 - 6 mm. At the housing versions, the sen-
sor cables have to be led through the cable gland and have to be connected to the
appropriate interface.
The different connection possibilities are summarised in groups in the following table.
Bus
optional
Standard sensor Inputs Outputs
I2C PT1000 2 wire 2 x analogue
0 - 2.5 V
2 x analogue
0 - 2.5 V
SPI PT1000 3 wire 1x analgoue
0 - 10 V
2 x digital
UART PT1000 4 wire 2 x digital
In case of need, all connections can be used simultaneously. Furthermore, the voltage
supply is possible over these terminal strips.
The sensor modules are optionally equipped with a switch off function that can be
controlled over the sensor interface.
The sensor module SM 230-G is available in an IP65 housing, the sensor module
SM 230 is available as PCB version.
The user can determine the measuring interval of every single sensor module in the
range of 10 s…1 year. The respective sensor module always sends latest measured
values after expiration of this time (also see chapter "Control software and software
interface").
Capacities (Min / Max) can also be determined for the analogue inputs as well as for the
PT1000 interface. The sensor module then only transmits valid measured values in case
these are within this range. In case a value out of this range is measured, an invalid
measured value (0x0000) will be sent (see chapter "Control software and software
interface").
The analogue outputs (channel 1 and 2) as well as the UART interface are deactivated
in case of battery operation in order to achieve a lifetime of the battery as long as
possible.

• data bits: 8
• stop bits: 1
• parity: without
• handshake: without
But please mind that no duplex operation is possible over the radio interface since no
separate channels for go-and-return channel are available.

A 2-wire connection is possible by default. If desired, a 3- or 4-wire connection can also be
realized by an optional adjustment of the hardware.
Following, you can see the appropriate connecting diagrams.

Description of device-specific features
Analogue In
The analogue inputs are for measuring analogue voltages (e. g. level transmitter).
There is a total of three analogue inputs available, two of them can be operated in the
range 0 - 2.5 V and one can be operated in the range 0 - 10 V. The analogue inputs
refer to AGND.
Analogue Out
The analogue outputs are for the activation of actuators with analogue interface. They
can be operated in the range 0 - 2.5 V and refer to AGND. Two analogue outputs are
available.
Digital In
The digital inputs are for measuring digital signals (e. g. limit switch, state signals). Two
digital inputs are available.
Digital Out
The digital outputs are for the switching of actuators or for the status output. Two digital
outputs are available.
Repeater module
The repeater module has the function to transfer the data within the network. In case
a sensor module is too far away from a base module to reach it directly, the range can
be raised by using a repeater. Thereby, it is possible to set up spatially long-range net-
works by means of sensor modules with low transmitting power. This raises the energy
efficiency and therewith considerably raises the lifetime of the battery.
The repeater modules have to send more often than sensor modules and have to be
ready to receive all the time since they possibly transmit packets of data of several
sensor modules. They are as a rule firmly installed at topological favourable points and
are fed by a power supply unit. In case of need, battery operation is also possible over
a short period of time.
The repeater module RM 300-G is available in an IP65 housing, the repeater module
RM 300 is available as PCB version.
When setting up the network, you have to mind that the number of repeaters in the
network is kept low in order not to stress the network excessively by manifold packet
forwarding.
Repeaters should also be installed in places with good radio propagation conditions
(e. g. isolated, elevated mounting places). This raises the range and the quality of the
whole network.
