Description
The SGA software, included in the standard equipment of EDAS data loggers manufactured by BOVIAR, is a visual application software,
running on Windows OS, designed to control all the functions concerning the full operations (programming, exercise and data visualization and
transfer) of the above mentioned loggers, via RS232 or USB serial lines.
The software is structured in six User Panels:
Main / Control Panel
It allows you to connect, either locally or remotely, to one or more
EDAS loggers. Further, the Scan ("Scansione”) function included
automatically detects any loggers’ network.
Configuration Panel With this panel you can access the system settings such as firmware
version, EDAS ID and serial number (these details, of course, cannot
be changed by the user); as well as set the parameters of the sensors
you are about to use: name, engineering unit, start-up time and gain, log interval and alarm settings.
Acquisition Panel
By accessing this panel you can check the logger status (Waiting / Stopped / Running), the memory status and also edit the logging strategy of your interest: date and time of acquisition Start/End,
Logging interval, Alarm settings.
Data File Panel Here you can access data files in memory and decide which are to be
displayed, transferred to Pc or deleted.
Alarm Panel Alarm events can be displayed - and, if desired, sent to Pc - via this
panel.
Measurement Panel The last panel allows you to display real time readings of the sensors either as numerical tables or diagrams.

Local Connection
For local connection, plug an end of the connecting cable supplied as standard equipment to the USB port of your PC and the other end to
EDAS RS232 socket.
Remote Connection
Remote connection requires previous installation of two modems
communicating via a dedicated GSM telephone line – one placed at the PC pole and to be connected to COM port (*) and the other one,
generally pre-installed, at EDAS pole.
(*) If your PC is only fitted with USB ports you need to install and use the
USB/RS232 converter supplied as standard equipment.
Both functions and controls remain the same regardless of the type of connection being used; hence the following instructions, referred to
local connection, are valid for remote connection as well.
As per remote connection, when setting the network configuration, you need to enter the telephone number associated to a specific EDAS
and/or EDAS network.
After doing this, save the Network configuration file in order to allow, further to the upload of the configuration file of your interest, the
automatic dialing of the number you have entered.

Calibration
The EDAS loggers, as any other measurement device of its kind, can only read voltage values (i.e. tension). In order to convert and visualize
Volt readings in different electric (e.g. mA) or engineering (e.g. mm, °C, bar) values, it is necessary to properly program each input channel
of the unit by using the correct calibration table.
There are two ways to input calibration values:
Automatic Manual
The automatic procedure involves the availability of further devices, varying according to the sensors to be calibrated (in this place we will
not discuss such details).
For manual calibration procedure, the calibration certificates normally supplied with the measuring sensors are used.
The calibration table of the EDAS loggers accepts up to ten calibration points and they are sufficient to ensure that an optimal signal curve is
achieved, even in case of poor linearity sensors.
For most sensors featuring a good linearity, entering only just two calibration points is more than enough and, generally, these two values
are represented by the sensor range limits (the highest and the lowest).
E.g.: Displacement transducer Measuring range -12,5 .. +12,5 mm
Electric output 0 ..2 Volt
If you have a look at the calibration table in a certificate you will find something like this:
Electric output Corresponding engineering
measurement
VOLT mm
0.000 -12.50
1.000 0,00
2.000 12.50

Here is the procedure to enter all the parameters of the sensors above in
the calibration table. Select the channel of interest and first set the parameters of your sensor.
Now you have to enter in the calibration table the two values indicated by
the arrows below (fig. 15).
Fig. 15 – Channel Calibration
Start with the first electrical value (2,000 Volt)
and the corresponding physical value (12,500 mm).
Click the button (“Nuovo elemento”) to add a new element. Repeat the same operation to insert the other values and, as you go on,
the table will display the data you are entering.
In case of mistake, select the wrong value from the table and delete it
with the button.
To be effective a calibration table must contain at least two values and has to be sent to the logger by clicking the ”Invio Configurazione” (Send
configuration) button.
Save new configuration with “Salva File di Configurazione” button.
WARNING!
Please be very careful during the procedure above illustrated as
any mistake in entering values into the calibration table will
invalidate the measurements read by your logger.

We already stated before that EDAS loggers only read tension values, i.e. Volts. So, if we connect a sensor with a current output (mA), we
would not get any meaningful reading, unless we do some specific operations.
Refer to EDAS Hardware manual – Chapter “Connecting Sensors” and
configure the input channel in order to accommodate a sensor with current output.
In accordance with Ohm’s law:
V(V) = I(A) × R(Ω)
from an input current of 4..20mA we get a corresponding tension, as read by EDAS logger, of 0.400 – 2.000 Volts (for R = 100Ω).
Hence, to get values expressed in the proper engineering units (as shown in the example on page 22) from a transducer with an output of
4..20mA, we need to go through a further calculation.
Let us consider a displacement transducer with:
measuring range -12,5…+12,5 mm
electric output 4…20mA
From the calibration certificate we may obtain the following table:
To convert readings in current:
To have readings in millimeters:

Acquisition Panel
Function
This panel is used to set an acquisition strategy, i.e to define and enter all the instructions about what you wish your logger to do, how often,
how long, when an alarm, if any, should be sent to whom and so on, as
detailed in the paragraphs below.
An operating strategy requires that the user has defined beforehand:
“Identificativo” / ID (assign a name to the logging strategy)
“Data/Ora Inizio” Start date / time and “Data/Ora Fine” End date / time (define logging duration)
“Intervallo” / Log interval (can be set for each channel)

Description of Controls
If you have a look at the “Acquisition Panel”, you will notice a batch of controls :
Data/Ora (Clock)
This box shows the date and time currently being used by EDAS
internal clock. Before sending a logging strategy to EDAS, check that these
details are correct.
Should you need to update this parameter you can use the “Synchronize clock” button (Fig. 11 above)
This will match the EDAS clock and the Pc clock, assuming this
latter is correctly set.
Identificativo (ID)
You can choose up to 12 alphanumeric characters to assign a name to your new logging strategy.
Data inizio e Data fine (Start Time / End Time) Two separate calendars are available to set the Start time and
date and the End time and date of your strategy. The current date is displayed in a red circle in the drop-down calendars that will
appear when you click either boxes, whereas the Start and End dates are highlighted in grey.
Intervallo (Interval)
A value expressed in minutes that defines the logging interval between measurements. This setting is independent, hence each
channel may have its own logging interval.
Allarme (Alarm) A value expressed in minutes that sets the interval for alarm
threshold checks, i.e how often the system shall check whether
the threshold alarm values set by the user have been exceeded. As above, this setting is independent (See Alarm Handling)
Soglia (Threshold)
A value expressed in reading units (depending on the user-set calibration) to define an alarm triggering range. This too is
independent.

Stato (Status)
This box shows the possible operating status of EDAS:
o Inattivo (Inactive) - No acquisition currently in progress; EDAS is waiting to receive operating instructions).
o Attesa (Waiting) – A logging strategy has been set but not yet started, awaiting the starting event set by the user
(Date/Time). o Attivo (Active) – Currently logging
o Fine (Ended) Logging ended as scheduled. o Fermo (Stopped) – Logging has been stopped either by the
user or due to any failure.
Starting an acquisition strategy
To start a new acquisition you will need to:
Check EDAS clock and, if needed, synchronize it with your PC clock
Give a name to your new logging strategy Set the logging interval for each channel of your logger.
You can enter any value greater than 0. Consider that channels
set with a value = 0 will NOT be logged Set Start date and time: allow for at least a couple of minutes to
cover the time needed to finish the programming operations. Check that all time settings are consistent (for example, is the
logging start date different from - and later than - the logger current date?)
Set End date and time, after checking that these too are consistent and compatible with the remaining memory capacity.
If all the settings that you entered as above are consistent, the Start logging strategy button (See Fig. 11) will activate and you have to click
it to send the designed strategy to your logger.
During this stage the status LED will flash (yellow-green).
The operations will be ended when the status LED turns to a steady
green light.
The Status windows (see Fig. 11) will notify the waiting notice “Attesa”.

Measurement Panel
Function
The main object of the Measurement Panel is to monitor that sensors are properly working during installation procedures and also to get real
time readings, regardless of the logging interval set in a logging strategy.

Readings via Node
To enable this mode it is assumed that you have already selected the node of your interest from Control Panel (“Pannello di Controllo”)
Now, from Measurement Panel (“Pannello di lettura” - Fig. 21), choose which sensor you wish to read.
You can enable the sensor by clicking the relative LED (Fig. 22):
Click LED when off = it turns on (enabled)
Click LED when on = it turns off (disabled)
Remember that at least one channel has to be enabled.
This will cause the button below to activate:
Avvio Acquisizione Dati / Start Logging Strategy – it will start
continuous readings of the enabled channel(s) whose data will be included in the table shown in Fig. 22. In the first line (containing
figures) you will find the real-time reading values.
Meanwhile the button will turn into this:
Pausa Acquisizione Dati / Pause Logging Strategy – it allows you to temporarily stop readings or to resume them by simply pressing again
the same button.
Interruzione Acquisizione Dati / Stop Logging Strategy – should you
wish to stop all reading procedures.

In this case, the button below will turn active.
Crea file Dati / Create data file – by default this will save the measured values to the following file path:
C:\Programmi\BOVIAR\SGA \Misure \xxxxxx.csv (*)
The measurement panel starts by default showing the table format but
it is also possible to represent values graphically as in Fig.23.
Modalità di Visualizzazione / Display mode – this button lets you
toggle, even when reading is in progress, between tabular and graphic displaying of data.

Special Configuration
Network Configuration
When you are going to interconnect a number of EDAS loggers, originally operating as independent units, as a basic assumption, always
consider that in a network no two the same ID’s are allowed.
Now, connect to the single loggers to be networked in order to enable
them to the purpose and set the network parameters (see on page 20 –
“Node Configuration – Manual option”)
Once you have completed all the configuration, connect the loggers to the 485 bus and provide power supply to the loggers (see “EDAS
Hardware Manual”)
Connect to one of the loggers, according to what previously illustrated, and proceed straightly to connection by clicking the relevant button.
After a couple of seconds you will be connected to EDAS.
Regardless of what is displayed in the Network
window shown on the left, start Scanning the network
by clicking the corresponding control: the pre-existing
nodes will be deleted whereas the new ones will be added to
the new list as they are detected and recognized by
the system.
The operation will end once the scrutiny of all the 255 possible nodes
has come to an end.
Note
The user may decide to stop scanning the network as soon as all the nodes actually
available have been detected, by clicking again the same control button.

Fig. 24 – Network scanning
Although the only essential requirement is that network ID’s must not
be duplicated, in order to speed up scanning it is a good practice to choose consecutive ID numbers starting from “0”.
The case shown in Fig. 24 above shows the point - to detect the fifth
logger in the network the procedure needed to go through 128 nodes!
In Fig. 24 it appears as well that the list of the nodes is updated after the full scanning procedure, whereas the details relative to the network
remain unchanged – the assigned name “Boviar” is still there.
This occurs because the parameters referred to the nodes are sent to
the PC from each node and, conversely, those ones relative to the network belong stably to the latest used “Network configuration” file.
It follows that, to finalize the configuration, you only need to give a
name to the new network and save everything to a new configuration file.

Here are the steps to take:
Stop connection to EDAS
Move the mouse onto the Network name Place the cursor within the window used to assign Network Name
(“Comandi” / Controls frame) Delete the current name, enter a new one and confirm by clicking
“Enter” on your keyboard – the network name will be changed. Save by clicking the “Save Network configuration” button
To perform further operations go on as previously illustrated.

Alarm handling
For each logging channel the user can set an alarm threshold with an associated checkout interval. In case a measured value exceeds the
threshold value EDAS shall:
- (on the spot) switch on an in-built relay so to trigger a beacon or a
siren, if any has been implemented - (remotely) send an alarm SMS to up to five cell phone numbers
(EDAS has to be equipped with a GSM modem)
For such settings refer to the Acquisition Panel (Fig. 16).
The threshold settings concern the following modes:
1. No-Alarm Range Threshold 0 < Threshold 1
In this case any value outside the range will trigger the alarm event.
ALARM No-Alarm Range ALARM
2. Alarm Range Threshold 0 > Threshold 1
In this case any value within the range will trigger the alarm event.
NO-ALARM ALARM range NO-ALARM
NOTE
When entering the threshold values always consider the type of
sensor and the associated calibration.
Threshold 0 Threshold 1
<<<<<<<<< 4 6 >>>>>>>>> -----------VALUE----------
Threshold 0
Threshold 1
>>>>>>>>> 6 4 <<<<<<<<< -----------VALUE----------

FTP Management
If your EDAS is equipped with an appropriate modem device, you can enable an automatic transfer of measured data to a FTP (File Transfer
Protocol) area of a server of yours or a third party.
You can do this by setting the FTP configuration parameters from the
Configuration Panel as follows:
Click on the button “Set access credentials to FTP”
(“Modalità Visualizzazione” / Display Mode)
You will be presented with the configuration screen below:
Please contact our Technical Area for proper configuration of FTP.
