FA-20, Brief about

Use: Data logger with GSM/GPRS modem.

FA-20 is our 5. generation of GSM/GPRS/SMS based remote metering
units, created for reading and logging data from heat, electricity, water
and gas meters. In a new way combines easy installation , fast data
transmission with the main database system(s), direct serial
communication with a large number of meters – besides of course
pulse capturing from pulse based meters and flexible data logging.

Description:

FA-20 is a complete unit; which is consisting of a quad-band
GSM/GPRS modem, data logger, 2 M-bus ports, 1 flexible meter
interface (supporting both M-BUS and a long line of manufacture
defined interfaces), 2 inputs for S01 pulses, power supply and antenna.

Collecting of data, setting up parameters and even software update is
done through the integrated Quad-band GSM/GPRS-modem, allowing
data to be transferred through GPRS, V110 and SMS. Data logging is
done with respect to the EDIEL-standard including EDIEL marking of
data. Logging of serial data and pulses can be freely mixed.

FA-20 is delivered preprogrammed with a number of serial meter
drivers, supporting different serial manufacturer protocols. Changing
between the drivers is easily done trough SMS, and just by using a
mobile phone, the installer verify the communication between the
meters and FA-20 WITHOUT help from personnel at the IT center.

FA-20 contains a unique M-bus driver (Max M-bus), which can read M­bus based meters directly (“plug and play”) WITHOUT the need of
encoding any information into the FA-20 at all.

Option: FA-20 offers the possibility of mounting an internal option

module. It can for example contain 2 analogue inputs (0(4)) to 20mA),
2 relay outputs and 4 inputs (pulse inputs after S01 norm or digital
on/off input). Other types of option modules are under development
(including wireless communication modules).

Product information FA-20:

GSM/GPRS/SMS based remote metering.

Description:

FA-20 is a unit for remote metering of heat, electricity, gas and water through the GSM
network.

FA-20 consists of a data collection module and a communication module. Through the 3 serial
inputs and/or pulse inputs FA-20 collects data, for later to return the collected data through
the built in GSM/GPRS/SMS modem.

FA-20 monitors the functioning of meters and consumption through alarm limits and – if the
meter has error recognition – the meters own error code. FA-20 offers the possibility for
extended data processing, as it performs data logging on as well pulse inputs as the 3 serial
inputs.

Data processing for serial data:

FA-20 reads the meter up to 96 times within 24 hours (programmable), and controls the
received data. To use with energy meters the FA-20 offers alarm limits for forward- and
return temperatures and a 24 hour consumption of heat and water (only applies the
multifunctional port).

In case of failure or alarm limit is exceeded, these conditions will be transmitted to the main
station through an extraordinary data communication (programmable).

Furthermore the FA-20 saves 3 sets of serial readings: The latest reading, the reading from
the last midnight and the reading from every change of month. These readings are present in
FA-20 – independently from chosen data log setup. I.e. it is not necessary to log such data as
time counter and error code – they are available anyway.

Data processing for pulse inputs:

FA-20 features serial inputs as well as 2 pulse inputs – complying with the S01 standard –
applying specifically to meters with pulse outputs of type S01 (DIN 43864), relay or
optocoupler. Lowest pulse width is 24mS and max. pulse frequency is 18 pulses/sec.

Every pulse input has its own 8 digits counter and the counter “flips-over” at 99.999.999 to 0
(zero). The pulse factor, if requested, is located in the main station. In case of power failure
the readings will be stored in F-RAM, where the stored data is not affected by power failure.

Data logging, Pulses:

FA-20 performs data logging of pulse counters with intervals from 1 minute to 24 hours
alternatively with intervals from 1s to 15s. The intervals are programmable from the main
station.

5

Data logging, Serial data:

FA-20 performs data logging of selected subjects from the serial meter telegram, e.g. energy
volume (m3) and temperatures of heat/energy-meters. The recommended logging interval is
from 15 minutes to 240 minutes.

FA-20 is not able to communicate with the main station at the same time as serial data is
collected from serial meters. This means that there should be left time between the loggings
for transfer of data. If it is acceptable that no data collection can take place while data is
transferred to the main station the logging interval may be reduced to 2 minutes for serial
data.

Data logging, capacity:

FA-20 performs data logging in a number of buffers from 1 to 12 (programmable from the
main station). Storing is based on the FIFO-principle. Besides buffers for the measurement of
data a buffer for timestamp and marking of data (EDIEL) of each logged measurement is
available. The number of storage spaces available in each buffer depends on the number of
buffers with measurement data:

No. of buffers 1 2 3 4 5 6

No. spaces per buffer 3000 2000 1500 1200 1000 850
No. of days (24 h)(1h logging) 125 83 62 50 41 33

No. of buffers 7 8 9 10 11 12

No. of spaces per buffer 750 650 590 530 490 450
No. of days (24 h)(1h logging) 31 27 24 22 20 18

The FA-20 is remotely programmed from the main station (logging parameters set-up and
selection of buffers to which data is logged). Logging of pulses and serial data are freely
combined.

Logging data is stored in the F-RAM which means that power failures with an
accumulated duration of less than 360days over an 8 year period will not lead to a loss
of data.

Description of communication:

In order to be able to call the FA-20 a working SIM-card has to be inserted. The SIM-card
holds information that enables the FA-20 to connect to a GSM network and a telephone
number to call.

V.110 data call:

By using the communication standard V.110 fast interconnection is established i.e. typically
within 6-9s from the call begins to a connection is established (CONNECT 9600). From here
on data can be transferred with nominally 9600 bit/s. The effective transfer speed is typically
less, partly because of the conditions in the package based network as the GSM-network
represents and shares as a result of sending/receiving conditions.

GPRS communication within APN network:

FA-20 supports GPRS within APN network, where fixed IP addresses are assigned either via
radio server or via the phone operators networking possibilities. GPRS is normally settled pr.
byte plus the GPRS ”transport bytes” without call charge, and GPRS will therefore normally
be cheaper for frequent data repatriation.

6

SMS with data after SaSat:

FA-20 supports SMS after SaSat: Standard for SMS format for transfer of logged values for
example an electric meter for a data acquisition system via SMS.

Service SMS with field strength measurement etc.:

FA-20 is able to send a service SMS to for example a regular mobile phone of the installers.
The service SMS contains among other things information about current GSM field strength,
pulse counters etc. The installer orders the service SMS by sending a regular text SMS to the
FA-20 containing a password.

"Dial-back":

FA-20 also supports the "Dial-back” principle, which is based on, the FA-20 takes initiative to
communicate data back to IT centre. The initiative may be due to time for routine
communication, alarm recognition or key press. FA-20 is programmed to carry out routine
communication either fixed routine every hour, day, week, month, 3. month or freely defined.
The interval between routine communications can be changed from the IT centre with effect
from the following communication.

To ensure against to many FA-20’s taking initiative to communicate on the same time, all FA­20 are equipped with special software. FA-20 chooses to delay the initiative to communicate a
random number of minutes, within a time window, which is programmable from the IT centre.

FA-20 also supports ”dial-back” at absolute time, where it is the main station who chooses the
time including date and month, in which the FA-20 needs to take initiative to communicate.

Duration:

Transport of data including establishment of connection will last (depending of chosen
communication method and local GSM conditions) from 15 seconds and up to more then 10
minutes, if all logged values shall be retrieved (the total logged memory) and if a download
also needs to be performed (installation of new firmware to the FA-20). The IT centre
acknowledges itself, how many log data it is necessary to transfer and controls the
communication after this.

Internal interval counter:

The FA-20 will log the total call duration in an internal counter with a resolution of 1 second as
an extra control option.

Protocol:

The FA-protocol is a full two-way, commando oriented ACK/NAK protocol with BCC-check,
format- and value validation. There are used encrypted passwords on multiple levels. The
protocol creates possibility for extensive parameter programming possibilities, where the
parameter setup is chosen via menus on the IT centre and installed on to the FA-20 via
GSM/GPRS communication. When GPRS is used the FA-protocol is still used as the data
carrying translation protocol, which are transported in the TCP/IP protocol.

7

New Software:

The unique download facility, which in many years have been implemented and tested in FA­products, is of course present in FA-20. FA-20 uses the newest version “Safe-load”, which
makes it possible to download new firmware safely and fast – in spite of possible interruption
of electricity supply or the GSM/GPRS connection. In connection with the data communication
– regardless cause and initiative of communication – the IT centre has possibility to download
new firmware to FA-20. After ended communication the FA-20 will reboot on the new firmware
and hereafter be running on the new firmware.

Antenna connection:

FA-20 is supplied with a SMA-connector for use of a short direct mounted whip-antenna or
other antennas with cable connection.

Signal lamps:

A green and a red light emitting diode (LED) for external indication of operation station and
internally a green and yellow LED for installing purposes and easy troubleshooting. A simple
"Fast-track" service guide describes "step-by-step", how possible errors may be identified via
LED and corrected.

Key: One key for activation of meter reading and subsequent dial-back.

Power supply: 230 VAC +-10%, 50 Hz. max. 50 mA.

Power consumption: Max. 10 W, typically under 1.5 W

Power failure:

FA-20 is equipped with a special permanent memory type called F-RAM, which without power
can preserve its content. Log data and for example the latest monthly reading is always
stored in the F-RAM which does not need a battery to preserve its memory

FA-20 features a special integrated circuit with a lithium battery, a clock-circuit which purpose
is to keep the FA-20 clock running during power failures. In case of a power failure FA-20 will
stop normal operation, but before this happens, the battery operated watch will be updated
with the system watch of FA-20. FA-20 will return to normal operation without clock error
when the power returns, since the system watch of FA-20 is updated by the battery operated
watch at power up. Logged values will be generated and marked with ”Power failure” cf.
EDIEL.

In case the operator requests the power failure condition to be dialed back, the FA-20 may be
programmed to dial back upon return of the main power supply. In all circumstances the FA­20 will update the IT centre about the power failure at the first available occasion. In
connection with this special dial-back the FA-20 unit applies random delay. This method
secures against overload of the IT centre and the mobile phone network.

FA-20 also registers both the time of the last power failure and power connection, besides the
total number of power failure and total time of power failure in minutes (possible to get further
information).

FA-20´s battery is placed in a socket, so replacement on the spot is easy. The expected
lifetime on a battery is at least 8 years with maximum 360 days of power failure.

Clock function:

Full real time clock function with month, date, day type, hour, minute, second, leap year and
summer/winter time.

FA-20's service clock uses a meted crystal as reference. Typical accuracy of the measured
crystal is better than 1 second pr. day.

During a power failure the battery driven clock circuit is used, typically with better accuracy
then 2 seconds pr. day. FA-20’s clock is controlled and set during communication with the
main station. Maintenance of the clock function can also happen via SMS.
