1. Introduction

DsLab3 software allows data acquisition from general purpose instruments,

supporting CANopen protocol and specific instruments of S2Tech with Modbus

protocol.

2. Requirements

Computer DsLab3 software can be installed on Windows 32-bit operating systems and is

compatible with Windows 2000, Windows XP (Home or Professional), Windows

Vista, Windows 7 (32 and 64 bit) and 8 (32 and 64 bit).

NOTE: For good quality of the measurements is good to pay great attention to

the quality of the earth connections used for the different components of the

measurement system and for all the components of the application, such as

inverters or other power organs that can generate electrical noise.

Take care not to cause earth loops, making sure that the measuring system has

common earth connections, as short as possible.

Measurement instrument

DsLab3 software allows the measurement and the transfer of data acquired

from the following S2Tech products, using the CANopen protocol and Modbus

RTU protocol:

• PITAGORA, firmware version 2.11 or higher.

• CANopen digital Load Cells, firmware (CM3_2013) or higher.

• CANopen digital Pressure Transducers, firmware (CM3_2013) higher. • CANopen Magnetostrictive Transducers,. firmware 1.00 (CM3_2014) or

higher

• CANopen 942DBCan Strain Link, (CM3_2009) or higher

• All S2Tech transducers / instruments with Modbus RTU protocol

Performance of measurement system

The transfer of the measured data, from the instrument to the computer, is a

function of:

• Connection speed, as set for the connection, and quality of the

connection itself;

• Characteristics of the USB connection on your computer (prefer USB 2.0

connections);

• Length of the connections for the CAN or Modbus network (RS485);

• Performance of the computer used for the measurement, of the

operating system, the capacity of the video card (limitations will result in

- 6/31 -

the operation of the measuring system using a video card without a

dedicated memory; in such case it is advisable to turn off real-time

preview of the acquired signal);

• Number of sensors / devices present and active on the CAN or Modbus

network.

• A/D Sampling frequencies used to sample the phenomena to be

detected, set in the individual measuring instruments.

For the characteristics and type of the CAN connections, refer to what is

available on the website www.can-cia.org.


- 7/31 -

Measuring limits of the acquisition system

The performance of the measurement system are affected by the number of

channels to be measured, by the number of devices on the CAN or Modbus

network, by the way data are published on the network by the different

devices, by the length of the connections and the characteristics of the

computer used for the management of the measures. The graphical

visualization of a large number of channels needs a greater workload at the

expense of performance. If fast acquisitions is needed, it may be necessary to

exclude the strip chart visualization.

In the program, moreover, are considered the following operating parameters:

Although not specifically indicated, S2Tech reserves the right to make changes

or variations in view of a constant and continuous improvement of the product.

The above is provided as an indication, as a result of the tests conducted by us

on the test computer.

3. Software installation

DsLab3 software communicates with devices using two protocols: Modbus and CAN. The software installation must be performed by a Windows user who has administrative rights.

The installation CD-ROM, supplied by S2Tech, install on Your computer the

following drivers:

• By selecting CANopen, the driver for the IXXAT USB to Can converter is installed (driver vci_218_setup.exe).

• By selecting USB, the drivers for the USB version of PITAGORA is

installed (driver VCPDriver.exe - Virtual Com Port).

• By selecting RS232/RS485, no additional driver will be installed, and you can communicate via Modbus protocol, on any installed RS232 or RS485 serial com port.

If there are problems installing the driver CANopen, refer to the documentation that came with the IXXAT CAN interface or the IXXAT web site ( www.ixxat.de ).

DsLab3 software is supplied on CD-ROM, or can be downloaded from the

website at www.s2tech.it .

The installation creates a DsLab3 folder in the Program Files directory. The installation software creates, in Start \ All Programs, a link to the software and an icon is set up on the desktop.


http://www.ixxat.de/

- 9/31 -

Installation sequence:

1. Insert the CD and run the setup.exe file. The setup includes the installation

files necessary for the application and installation of the needed drivers

(CAN / Modbus) for communication with the device.

2. Pitagora CAN - At this stage do not connect the USBtoCAN interface to

the PC (if you are using the device Can).

3. After software installation a restart of your computer is needed.

4. Connect USBtoCAN interface (only for devices Can) and finish the

installation of the operating system files needed for the proper

management of the interface. At the end of the installation process, verify

that the USB LED on the IXXAT interface is turned on, signaling that the

device connection is working properly. Note that USBtoCAN interface will be

properly handled by Your computer if it is always inserted on the USB port

where it has been installed the first time.

5. When the installation program ends, DsLab3 program is launched,

presenting the main window.


- 10/31 -

Activation code (CAN & Modbus)

Measurement system is provided with a paper/PDF sheet containing the

activation code linked to the type of interface to use.

• For IXXAT interface USB to CAN, code is tied to the serial number of the

interface (eg. HW123456)

• For the Modbus protocol it is linked to the serial number of the instrument,

shown on the label on the top of the instrument, or shown on the display

during the power on (eg SN 1234)

If the interface is not provided by S2Tech, at the purchase the program prior

notice must be given indicating the serial number of the interface You intend to

use, so that and activation code can be generated for the program You wish to

use. Product activation and binding to the Instrument’s serial number is

required for all devices.

Prior activation, make sure You have connected to the computer's USB port the

USB/CAN interface (USB LED powered on).

When first acquisition is activated (FAST, LONG

or DELAYED) a window is presented where you

must enter the activation code.

Type it, as shown in the provided

documentation.

This procedure is performed at the first use of the program and is no longer

performed if the program accepts the input code.

If a new instrument/USBtoCAN interface is connected to the program, then a

new activation code is needed and the program will not acquire any

measurements until the activation procedure is correctly ended.


- 11/31 -

4. Use of the DSLab3 program

Checks before execution

Before You run the program DsLab3, verify that:

a) The measurement system, consisting of the transducer connected to the

measuring instrument PITAGORA or other CANopen / Modbus

transducers or devices are working correctly.

b) In the case of CAN connection, the measuring system should be

connected to the IXXAT CAN interface installed in the PC (Green LED

powered on, close to the USB CAN / USB converter label) and that the

CAN bus is terminated with two 120 ohm resistors, to both ends, if You

do not use the wiring and equipment supplied by S2Tech S.r.l. Proper

selection of network cable is important (twisted pairs, shielded CAN cable

to be used).

c) If the DSLab3 program works as MASTER CAN on the network (NMT

functions active and/or SYNC activated) there must not be other units on

the network that operate as CAN MASTER.

d) Is USB connection has been chosen, verify that the Virtual COM port is

present on the list of the peripheral active on the computer.


- 12/31 -

Execution

If the tests of the previous section gave a positive result, activate the program

which will present You the main window as for the following image.

The first step to be performed is to set the type of communication that You are

going to use with the measurement instruments, with the corresponding

parameters for the connection.

Program stores the connection settings as default parameters for next

execution of the program.


- 13/31 -

Establishing the connection

The [Communication settings] window allows you to set the connection

parameters with the device, which may be via CAN or Modbus.

CAN connection settings

If the measurement system is not working, check the CAN LED placed on the

CAN/USB adapter. If it is not powered on or it is red, check the connections of

the network, verify the presence of the two line terminating resistors and verify

that all attached devices are set with parameters corresponding to those set in

the communications program.


- 15/31 -

Impostazione dei dati da visualizzare – Channel Manager

The [Channel Manager] window, also recalled with the Channel menu \ Setup

is used to set the channels to be acquired and displayed on the strip chart

graph, on the numeric displays and to be save on the data files. Depending on

the connection type and used protocol, this window may presents different

data fields for setting the characteristics of the channels.

Modbus mode

The S2Tech Modbus device, when properly connected to the PC, is queried by

the DSLab program, at the start, in order to know the hardware installed on

the different available slot. The term "slot" refers to a data acquisition card

installed inside the instrument PITAGORA (depending on the configuration

required at time of order).

Each slot provides a set of measurements that can be converted into

"channels", to be display and handled by the DsLab3 software.

Each channel is defined as the sum of the selection performed using the drop

down list "Slot", referable to the slot of interest (A, B, C or D) and the drop


- 16/31 -

down list "Measure" where the measurement type is selected among those

available for the selected slot.

Enter through the box "Label" the name/description of the channel You are

going to set up and a unit of measure by means of the box "Eng.Unit".

For each channel it is also possible then to configure:

1. Linearization / conversion of measures (Linearization).

2. Properties of numeric digital displays (Display properties) and graph

representation of the measured data (Chart trace properties).

3. Trigger activated acquisition (Trigger options)

In order to apply the desired settings to the Channel of interest, select it from

the "Channel List" table, so that the channel that you want to change settings

is active. confirms the selection of the channel object

for changes to the acquisition parameters (in the example, channel 1 has been

selected).

The pushbutton allows you to define a new channel. If you select

from the list of available channels an existing channel as template, after

setting the appropriate information of Node reference and Mapping for the new

channel (not the same as an existing channel), by pressing this button You will

create the new channel, based on the settings of the existing channel.

The pushbutton is used to confirm and save all the settings

and / or variations made to the selected channel.

Use instead the pushbutton to remove and delete the selected

channel (no confirmation is asked).

CAN mode

Configuration

The Configuration block configures the

measures to display.

The basic data are:

• Node – CANopen node, from

which it to be taken the PDO that

contains the data to be acquired, shown (strip chart and/or numeric

display) and saved.

• Mapping – Chooses the portion of the PDO that carries the data of

interest and the location of the data within the PDO. The suffix "a" refers

to the first 4 bytes of the PDO, while the suffix "b" indicates the last 4

bytes of the PDO selected.


- 17/31 -

PDO-1a PDO-1b

PDO-2a PDO-2b

PDO-3a PDO-3b

PDO-4a PDO-4b

• Label – Label assigned by the User to the measure channel.

• Unit - Units of measure (optional) to be displayed next to the acquired

value.

• Channel type – channels defined on the channel list may be Rea! (linked

to an existing physical resource (A/D channel) of the connected

Instrument, or Virtua!, if they are the defined as the result of

math operations on real channels (optional feature)

The configuration of the channel, relatively to the CAN network, is required to

indicate to the program the characteristics of the data packets, said PDO, in the

CAN network (Node and reference PDO) so to associate the measurement units,

the display characteristics and / or conversion into mechanical units or the

different display properties. An instrument can make available different types of

data and this requires the selection of information (such as PDO type) to be

used for the acquisition of the measure of interest.

S2Tech default configuration parameters

Each instrument on the CAN network is characterized by a unique node

reference (NODE). This parameter, in addition to the baud rate is needed to

connect to the instrument and receive the available measures.

According to the type of instrument to which You are connecting, different type

of measures may be available. Please refer to the connected product’s

instruction manual, for a list of the available measurement and their

description.

Display properties

The Display properties

block configures two

alarm levels and the

colors to be used for

used on the numerical

data display:

• Normal – Set

the Minimum

and Maximum values within which the measured value is displayed

in the Normal color (green in this example, or if


- 18/31 -

Normal MIN ≤ measurement ≤ Normal MAX).

• Level 1 – Set the Minimum and Maximum values within which the value

of the measurement is displayed in the color Lev 1 (in Yellow for the

above example), if Lev 1 MIN ≤ measure ≤ Normal MIN or Normal MAX

≤ measure ≤ Lev 1 MAX.

• Level 2 – Sets the color used for displaying of the measurement, when

the measurement value exceeds / is larger than the limits set for Lev 1

(in Red, measur3 ≤ Lev 1 Min and measure ≥ Lev 1 MAX).

The program requires and checks that the values of the limits

of the Normal zone are internal to the values of limits of zone

Lev1, as well as the numerical values of the limits set for Lev1

must be internal to the values set for the Lev2.

The pushbutton / activates /

deactivates the numeric display of the selected channel.

DECIMAL POINT setting in Display properties

The decimal point position is automatically set by the program.

To change the decimal point position, modify it directly on the setup menu of

the PITAGORA instrument so that any change is automatically transferred to

the computer (for the procedure, see section 6 of the PITAGORA instruction

manual).

When connecting to a PITAGORA instrument, DSLab queries the device for the

value of the PSDP parameter (see PITAGORA’s manual) and if value is defined

for the decimal point position, then also the acquired value on the DSLab will

be shown using the same settings of the instrument.

K factor

The K factor block configures, for each channel, a multiplier

coefficient that is applied on the measurements of the channel

where it is needed a value different from 1 (no K effect on the measurements).

Each channel can have a different K value assigned and the defined value is

displayed on the channel list.


- 19/31 -

Chart trace properties

The Chart trace properties block configure the color and

line thickness of the line corresponding to the selected

channel for the Strip Chart graphical display of the acuired

data; pushbutton /

enables or disables the graphical

representation of the selected track.

By pressing the Color pushbutton you set the color of the graphical trace

that will be represented with a thickness equal to the amount set as Line width.

It is suggested to choose a high contrast color with reference to the

background chosen for viewing Strip Chart.

Consider the combination of the colors chosen in relation to the color of the

Cursor XY, used to display the numeric values from the waveform.

By setting the numerical values Y min and Y max, you set the display limits of

the Y axis for the selected channel, so to represent it properly when autoscaling

option is not in use.

Linearization

The Linearization block configures the parameters for the linearization of

measurement displayed on the PC, allowing the conversion of units of measure

(numeric display and Strip Charts); the data acquired by the instrument can be

used as received from the network (CAN or Modbus) or it can be converted by

an algorithm running locally on the PC; in the latter case it is necessary to set

the known points of reference for the linearization X0, Y0 and X1, Y1 enabling

the linearization function by means of the Enable control (as in the image); it is

possible to capture in real time the value of X0 and X1 from the instrument

for the selected channel, by means of pushbutton , placed to the left of


- 20/31 -

each control. X0 and X1 are expressed with engineering units and

resolution used internally by the instrument. For correct conversion, verify

that the value is different from X1 to X0, as should be also different Y0

from Y1.

Measurement and storing of X0 and X1 points can be performed only if the

Instrument is connected to the computer and the program is in position to

connect to it to perform the needed live measurement.

To display the resulting linearized value with a desired Decimal point position

set the appropriate value in the corresponding input field.

In example, to display two decimal enter 2 and insert the full scale value of Y1

with as integer.

EXAMPLES:

• If you want to have shown 10,00 Kg, enter 2 as decimal points and Y1

value 1000.

• If you want to see 10,000 Kg, enter 3 as decimal points and 10000 as Y1

value.

Offset Value

The Offset Value block allows to define, for the selected

channel, a zero value that will be used as tare to be

algebraically subtracted to the measurements of the

channel. It is possible to set a numeric value (using the

same format as the one of the data transmitted by the

instrument for the selected channel), or it is possible to

use a measured value, by pressing the ____________ pushbutton.

If the linearization was active for the channel in question, the value obtained is

already represented converted. To remove the zero tare, press the button

.

Trigger options

The Trigger option block allows you to set a trigger

threshold (trigger value) for only one of the available

channels. According to what has been set as logical

condition, you will have the activation of the

acquisition (with display and optional data storage) if

the value:


- 21/31 -

measure > set Trigger value, or if

measure < set Trigger value

The pushbutton / ________________ allows you to enable /

disable the trigger mode corresponding to the threshold set.

The program indicates the activation of this function in the "System status",

showing the channel and the set trigger value.

Before trigger condition is reached, the program displays the measurements

only through numerical display (if enabled).

Measurements data are displayed (numerical and Strip Charts) and stored in

the log file solely when the trigger condition is met.

The acquisition of the waveforms on the Strip Chart graph is temporary

stopped by opening other windows or by activating other functions.

The above affects only the graphical displaying and it is therefore advisable to

prepare all the necessary settings before starting an acquisition, so to capture

the view in its entirety.


- 22/31 -

5. Data acquisition

Program Interface

Through the use of the menu bar and the graphic interface of the program it is

possible to set how measurements must be acquired and represented.

Acquisition Menu – acquisition type

Allows to start the acquisition of measurements, by selecting the measurement

mode that allows the best representation of the phenomenon of interest.

• Acquisition\FAST: This measurement mode is suitable to capture fast

phenomena and is characterized by a high utilization of computer

resources (graphics, data processing and storage, if you wish to save the

data on your hard disk). To make possible the graphic display, in this

mode of operation are displayed a reduced number of acquired points

(10%). Stopping the acquisition of the program will rebuild the display of

the acquired measurements, with 100% of the measured data.

This acquisition mode has to be stopped manually, using the button

available from the System Status panel, from which

it is also possible to start the

acquisition, by using the button .

• Acquisition\ONLY FILE (hi-speed sync use):

starts acquisition WITHOUT the graphic representation of the

measurements on the strip-chart (blind acquisition); this mode allows

you to capture data at the maximum possible speed (in relation to the

management of operating system processes), avoiding that the overhead

of drawing the graphics may slow down the collection of data with

possible loss of data. The status panel (System status) informs that a

"blind" acquisition has been activated.

By activating this acquisition You will be asked for the name of the data

file that will contain the acquired measurements. During the acquisition,

the acquired data are displayed on the numeric display, for those

channels where this setting is enabled in the Channel Manager.


- 23/31 -

• Acquisition\DELAYED: activate acquisition with a delay set by the user. It is

possible to delay

the start of

any type of

acquisition, for a

predefined number

of seconds set by

the user.

Cannot exist –

simultaneously -

two conditions for the beginning of the acquisitions, so you need to

disable any trigger conditions set on a single channel, to have that this

acquisition mode work properly. The program requires that all the

necessary information for the selected measurement mode have been

entered. When activated, you will see a timer that shows the time

remaining before the start of the measurements. It 'possible to delay the

acquisition of a maximum of 10.000

seconds.

• Acquisition\LONG: this acquisition mode

is suitable to be used for relatively slow

phenomena, where the phenomenon is

properly sampled with a cadence

measurement set using the data entry

field "Sample every", ranging from 0.5 to

60 seconds.

The program ends after acquiring for a preset time, set by the user

in the "Duration" field, being able to make the acquisition last for a

maximum of 30 days. The acquisition can be ended, manually, by

pressing the button _______________ on the System Status panel.

• Acquisition-Stop: acquisition is ended. If acquisition was intended to save

data on a log file, it is closed.

- 24/31 -

File Menu

File\Create new log file: allows you to define the name and location of the data

file that you want to create. A standard Windows operating system input

window is called to define the file name and storage location.

When you set the file name it should be remembered that if you select the

name of an existing file, the data contained in it will be overwritten. The

program does not append any of the measures on existing data file.

File\Open log file: Opens a data file

previously acquired, so to be able to

display and analyze data.

Using the button a window opens

letting you select the files of interest.

The window displays basic information

related to the acquired channels, the

characteristics of the file (acquisition

duration and size), offering the

possibility to reproduce the channels

and the time window of interest.

It is possible to choose to work with all

the data contained in the file, taking

long time to process them if

phenomenon required a long time data

acquisition. Otherwise it is possible to

select a portion of interest, using the two

sliders "Acquisition time selection ", to

define the beginning and the end of the

area of interest for display and analysis of

acquired data.

The name of the file whose data are

plotted on the Strip Chart window is also reported on the top windows frame.

File info: contains some information about

the characteristics of the file.


.

- 25/31 -

Channel list selection: through this

section are selected channels of interest

so to show more clearly the details of the

channel (with the acquisition of multi-

channel), limiting also the processing

time for large files, obtained with high

sampling.

Having carried out the channel settings and time intervals of interest you can

export the data in a tabular format, such as text files, with the button The data

is exported as a list with columns delimited by a TAB, inserting the Timestamp

(in seconds) created during the acquisition, so to obtain all the information

necessary for proper handling of the acquired data, for example through a

spreadsheet.

NOTE: when you activate the acquisition having defined a data file, it will be

used by the program to store data in binary format, to be more efficient in

terms of performances.

The data file is closed at the end of the acquisition, when you use the

command Acquisition-Stop. When you start a new capture data, if you do

not define a new file name, the program uses the existing reference

and overwrites the previously stored data.

Having selected the channel and the time interval of interest, with the button

is generated a graph of the acquired measurements, using the maximum

definition allowed by the data acquired, while using the button

data visualization is achieved using 50% of the available data,

so you can quickly represent acquisitions characterized by a considerable

amount of data.

Channel Menu

Allows you to customize the display of the different channels that can be

acquired from the program.

Display Menu Zoom - : reduces the size of the display that represent the acquired

measurements as a numeric value. Zoom + : increases the size of the display that represent the acquired

measurements as a numeric value.

Software Menu

Displays the version of the program.


.

- 26/31 -

Acquisition interface

The User Interface provides several information and measurement

functions. Numerical data display window

Displays the measurement using the measurement

units defined in the "Channel Manager".

The dimensions of the display are

• increased with the function Display\Zoom +

• decreased with the function Display\Zoom -

The displays show the measured values for all channels

where "Display properties" was set to

It is possible to represent, at the

same time, measurements in expressed in A/D points or converted

measurements in engineering units via linearization. In this last case, the

decimal point is a function of the settings related to the conversion, for a

maximum of 3 digits after the decimal point.

System status Window

Indicates whether the acquisition is active (flashing

LED status indication and "STATUS START"), as well

as:

Information relating to the CAN network

• Connection Status

• Sync Value used to querry the devices in the

network to obtain measures

Information relating to the Modbus network

• Connection Status

• Rate of acquisition set

Informazioni relative all’acquisizione in corso

• Type (FAST / LONG / DELAYED / ONLY FILE)

• Sample rate, in seconds

• Date and start time of the acquisition

• The date and time scheduled for the end of the

acquisition (LONG and DELAYED acquisitions)

Pushbutton _____________ , to activate a FAST data acquisition.

Pushbutton __________________ , to terminate any type of active acquisition,

closing at the same time the data file on which the measures are eventually

saved.

Information regarding the trigger function for the activation of the acquisition

• Trigger Type (an increasing / decreasing measurement toward the set

trigger value)

Information about the data file created to store measures

• Name of the data file

Remember that each time a new acquisition is started, with a data file

associated to it, a new file name must be assigned, in order not to overwrite

the existing acquisitions. The program does not append any of the measures

on existing data file.

Strip Charts Window

Used to display graphically the data, as a strip chart, as live measurements

coming from configured channels or as data coming

from log files saved on hard disk.

Data is displayed with reference to a settable time base.

The X axis scaling is suggested by the program in

relation to the type and duration of the acquisition in

progress. It is possible to set manually the desired

value, indicating to the program the amplitude of each

division for the representation of data.

The displaying of the Y-axes can enabled or disabled by

selecting "Axis info". It is possible to activate ________ or

deactivate ___________ the autoscaling of the display of all

acquired channels.

This replaces what is set in the "Channel Manager", as minimum and maximum

for the representation of the measured data, with respect to its axis Y.

It is possible to set the background color on which are plotted the

acquired data.

It is also possible to activate the displaying of the acquired points

using "Trace points" function.

On analysis of the acquired waveforms, this option makes evident the density

of the acquisition points so to evaluate the quality of the acquisition in relation

to the phenomenon, allowing the optimization of the sampling settings.

When viewing waveforms (recalled from file or

obtained from a live acquisition that has been

stopped) You can use the following functions

Zoom in: through the cursor and the mouse it is

possible to define graphically an area of the waveform

that you want to see in a more detailed way.

Zoom out: allows to get back to the previous

level of view/zoom of the displayed waveform.

Pan: holding down the left button of the mouse allows you to move the

display window, maintaining the current zoom level.

Cursor XY: displays a cursor in the center of the display (marked with an

X) freely movable on the waveform, showing as separate over imposed

window the values of the selected point on the waveform, as time value and

acquired measurement (if enabled by the corresponding linearization ).

LONG displaying: after Zoom In / Out functions have been used, it allows

to restore the display of the entire waveform acquired with LONG.

Pressing this button will enable printing of the waveform

currently displayed, with statistical data, if available.

By pressing this button, you can define the printer and

number of copies you want to print the area of the

selected waveform.


- 30/31 -


The print preview windows shows information like the path of the log file from

which the plotted waveform has been loaded to be displayed, plus all the

statistical information calculated on the selected channel of interest.

Statistical block:

Allows to select from a drop down list the active

measurement channels.

After having selected the channel of interest, the program

compute the available statistics on the basis of a live

measurement or on the basis of a waveform loaded from a

log file previously saved on disk.
