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.

PC requirements

Below are the minimum requirements of the Pc to be matched with the unit: Processor: 800-mHz Pc pentium III RAM: 512 Mb H.D.D.: 10 Mb free space

Video card resolution: 1024 x 768 Operating system: Windows Seven and later versions

CD drive Microsoft Office

Adobe Acrobat Reader

SW Installation Insert the CD supplied with the equipment into the PC drive and then select the corresponding device from “Computer”.

Select and run “SGA vXXX.exe”.

If you are using Windows “Seven” or a later O.S., perform this procedure as “Administrator”. Follow the prompts suggested during installation operations.

A message will finally confirm that the operation has been successfully

accomplished.

Now you have to install the driver(s) of the connecting cable:

1. Insert the USB connecting cable supplied in one of the free USB ports of

your PC. A step-by-step procedure will start to search for the driver of the new device.

2. Direct the search along the path: C:\Programmi|BOVIAR\SGA\Driver

3. Wait for the final message confirming that the device is now

installed and ready.




- 6 -

NOTE For Seven and later O.S.’s run the application “CDM20814_Setup” included in

the folder “Aggiornamento Driver TTL232 042011” of the Installation CD.

Perform this procedure as “Administrator”.

At the end of the procedure the system will recognize the device newly installed as a communication serial port:

USB Serial Port (COM “N”), where “N” is a number that the O.S. will automatically assign to this port and hereafter will identify as the

communication port between your PC and the logging unit. Check that this number is not greater than “9”.

If necessary, modify as follows

“Pannello di controllo” / Control panel;

“Gestione Dispositivi” / Devices; “Porte COM-LPT” / COM-LPT Ports

USB Serial Port – “Setting Port” – “Avanzate” / Advanced.

Once the installation is completed, you can run the program from the menu:

Control / Main Panel

Function

This is the first panel that your screen displays when you first launch the

software. From here you can proceed to connect PC to EDAS (“Node”).

Once a connection is established, you will be able to access all the other Controls / Configuration / Management Panels available.

Before proceeding please check that:

the logger is powered (see EDAS HW manual)

the connection of PC to EDAS is actually active

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.

Fig. 6 - “File Configurazione linea” (Line Configuration file)

In order to establish a connection with EDAS proceed as per previous section. Both modems are to be correctly installed and connected.

NOTE

The procedure of upload configuration file above illustrated is no longer

requested since the Installation CD supplied as standard equipment now

includes a new application (“Serial Configurator”) by which you can

properly configurate your modems.

If you wish to disable the Remote Connection procedure, delete the phone number from the network configuration parameters.

Scan

Once received the message confirming that you are now connected to the network (“Connesso alla rete”), click the Scan button (see Fig. 3

top-right) in order to get info from the connected logger.

This procedure will automatically scan the 255 potential Nodes. The nodes detected will appear in the “Rete” / Network area.

Whenever you wish, you can manually stop the scanning progress by

clicking again the same button as above.

Note

All loggers are configured with “0” as default network address; hence, to have your network loggers to come into view, you should configure

them one by one earlier (See Configuration Panel), except for the case of those units pre-configured as a result of a specific agreement with

our engineers / sales personnel at the time of order.

Select the Node you wish to connect to: it will highlight and the buttons of the “Comandi” / Controls frame will turn active.

Fig. 8 - Connecting to a Node




- 15 -

Now, the connection to the Node is established and you can access the different functions available.

Explode the NODE by clicking “+” on the left of “Nodo” and you will be

able to get info about Name and Serial Number of your EDAS.

Similarly, if you explode a single channel by clicking “+” on the left of “Canale” you access the Name and Engineering unit assigned to that

channel.

Node Configuration – File uploading option

The internal memory of your EDAS includes a file containing the original

basic configuration of the unit and also, if so agreed at the time of order, the calibration details of the various sensors to be connected to

the logger as well as the sensor-channel matching entered by BOVIAR

engineers before delivery.

NOTE

We do recommend to save a copy of the pre-existing configuration file

before making any change to it (see “Saving configuration”).

It follows that the simplest way to configure a Node is to upload the

relevant configuration file.

You can do that like this:

Click “Carica File di Configurazione”

(Upload Configuration File) control and the screen on the right will

appear.

Fig. 12 - Upload Configuration File

Select by double-clicking the configuration file you wish to upload and a

screen like the one on next page will be displayed on your screen.

Fig. 13 – Node Configuration Panel (already configured)

Note

To become operational, the data just uploaded and displayed by the screen Panel need to be sent to EDAS.

Click “Invia Configurazione” (Send Configuration) control.

An eventual message will ask you to

confirm operation. Click “OK” to confirm.

WARNING!

All pre-existing data will be deleted!

During this stage the status LED will flash (yellow-green) and the progress bar will move forward.

The procedure will be completed when the LED above will turn steadily

green.

Node Configuration – Manual option

The default configuration file is to be taken as a starting element to any:

new configuration sensor addition / replacement

change in channel-sensor matching

To this purpose it is necessary to manually enter / modify data.

Enter the requested parameters as described in paragraph “Node

Configuration – Parameters” further ahead.

Node Configuration – Saving configuration

Once you have completed your Enter / Modify actions, proceed with saving the file as follows:

Click “Salva File di Configurazione” (Save Configuration file) control:

the windows on the left will open and you have to assign a

Name to your configuration and then to click “Salva” (Save).

The new file will be added to the “SENSORI” list and can be uploaded whenever needed.

Fig. 14 – Save Configuration

To make any change made become operational, follow the same

directions as per previous paragraph.

WARNING!

You can enter or modify parameters only if no acquisition is under

progress.




- 21 -

Node Configuration - Parameters

“Nome Sensore” (Sensor name): Enter up to 12 alphanumeric

characters for sensor identification

“Unità di lettura” (Engineering unit): this is the measurement unit (mm, °C, etc.) in which the values read by EDAS are to be

expressed. Of course, this implies that you have already entered the conversion values from the calibration table of each sensor

“Anticipo alimentazione” (Supply Start-up Time): the value

that defines the specific pre-warmup time (in mS) requested by

the sensor before logging a correct measurement

WARNING!

To set this value refer to technical features of the sensor being used

(see also standard sensors table)

“Guadagno amplificatore” (Amplifier Gain): this value can be set from 1 to 20.

WARNING!

To set this value refer to technical features of the sensor being used

(see also standard sensors table)

“Id Rete” (Network ID): this is the Network address

WARNING!

This parameter can be set at a value ranging from 0 to 255, taking into

account that you cannot duplicate any ID. If your settings do not comply

with these requirements, the whole system will not work properly!

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




- 23 -

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.

Load configuration file




- 24 -

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)

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.




- 27 -

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”.




- 28 -

Now the Start button will turn inactivated and, conversely, the Stop

Logging control (see below) will become enabled.

Warning!

Should you wish to start a new acquisition strategy, once saved them into a file on your Pc, you will have to delete all existing data from

EDAS memory (See “Data Panel”)

Stopping an acquisition strategy

Click the button control to stop the acquisition underway.

Deleting an acquisition strategy

WARNING!

This operation will cause all stored data to be deleted. Be sure to have saved your measurements on your Pc before

proceeding (see Data Panel).

Click this button if you wish to delete an ended or previously

stopped acquisition.




- 29 -

Data Panel

Function

The Data Panel is meant to show the status (“Stato”) of the current acquisition as well as the details about storage space, i.e. the number of

readings still possible (“Disponibili”) and the number of readings already stored (“Utilizzate”).

It also allows you to access stored data and to save them to your Pc.

Fig. 17 - Data Panel

A large frame contains a table with details about your logger channels.

From left to right you get the following columns:

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.




- 36 -

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.




- 38 -

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.




- 39 -

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----------
