1. Introduction to DA Package:
Welcome to DA Package:
This Data Acquisition Package provides complete solution for data
acquisition, presentation, analysis and storage for various process industry
applications.
This package is designed ready to use. Most of the common screens are
created and they are available for just a click on menu item or a button on
toolbar item. This package is developed with high performance language
(VC++) and data storage is also done in more optimized way.
All data is stored with its time stamp, so keeping track of time is a snap too.

System Requirements:
Any x86 based computer capable of running Windows 2000, XP or later
versions of OS. We suggest at least P-II 350 M.Hz Processor, 64 MB of RAM
and 20 MB of hard disk space. The program is designed to be responsive
even under processor strain.
To run this package, monitor resolution should be 1024 X 768. So your
system monitor required to be set to this screen resolution before starting the
DA Package.

Licensing DA Package:
This package comes with a hardware key. Without a key if you start the
package then it will run in a demo mode for 2 Hours and the end of 2 hours it
will automatically shut downs.
If you start the DA package without Hardware key then the following dialog
will prompt to take feed back from the user either to switch to evaluation
mode or close the package.

To get the Hardware key you can contact your DA package provider.
What is Data Acquisition?

________________________________________________________________________ 4

________________________________________________________________________

Data acquisition is the process of gathering process da in an automated
fashion from analog and digital measurement sources such as sensors and
other devices. Data acquisition uses a combination of PC-based
measurement hardware and software to provide a flexible, user-defined
measurement system.
Basically, any computer based Data Acquisition system consists of Acquiring,
Monitoring the process data, Presenting, Analyzing and finally Storage it for
further processing. This DA package provides support for all the above
functionalities.
The block diagram of PC based Data Acquisition system is shown in below
fig:

At presently this DA packages provides the following set of protocols to
communicate with DA Hardware (Including PLC’s, PID Controllers, DA Cards,
etc., ). The below set of protocols communicate with Hardware either over
Serial bus or Ethernet.
- Modbus Serial –RTU
- Modbus Serial – ASCII
- Modbus Ethernet
In addition to above protocols this package supports OPC Client interfaces.
So any of your hardware device have valid OPC DA Server then you can
easily communicate with your device through OPC Client.

To develop your custom drivers for your proprietary protocols over your
choice of communication medium (i.e., GPIB, USB, ZigBee, PCI, PXI, etc.,)
we will provide Driver Development wizard. So you can easily build the driver
and start acquiring the data with this package.

DA Package Installation and Directory Structure:
________________________________________________________________________ 5

________________________________________________________________________

Once running the installation software, you can accept most of the default
settings. In the Installation Folder dialog you can enter the location for this DA
Package.

Once Installation completed, in the installation folder the following directory
structure will be created:
- In the Alarm directory Alarm & Event related files are stored.
- In the Config directory all sets of configuration files will be saved.
- In the Data directory, Historic data will be stored.
- In the Drivers directory supporting communication drivers will be reside.
- In the Help directory, all help files will be reside.
- In the Log directory every day log report will be stored.
- In the Report directory the generated reports will be reside.

In addition to this, short cut in the program folder will be created and a Icon on
the desktop will be created.

Take note only one instance of this package will run in a system. (i.e. you can
instantiate multiple instantiations of this package in a single system).

2. DA Configuration Dialogs:
Channel Address Configuration:
You can access the Channel Address Configuration dialog by clicking on Set
Address button on Front panel.
This Channel Address Configuration dialog is available for Administrative
privileged users only. For more on Administrative privileges see the Login
Management chapter.
Once communication with device is established this Set Address button is
disabled. Once disconnected the communication this button is automatically
enabled if the currently login user have administrative privileges.
In this Address Configuration dialog you can set the Start Address and the
No of Registers. Address configuration dialog is shown in below fig: You can
easily switch between Read Only channel types and Read Write channel
types by selecting the different options in the Select Channel Type radio
button.

AI: Analog Input or Read only registers and each register will hold 16 bit
value to get the data from external source.
DI: Discrete Input or Read only Discrete Inputs. Each register will contain
single bit to get the data from external source.
AO: Read Write Output registers or Holding Registers. Each register consists
16 bit numeric number is used to get or set the data from external device.

________________________________________________________________________ 8

________________________________________________________________________

DO: Read Write Discrete Outputs or Output Coils Consists 1 bit length used
to drive output data to a digital output channel.
Example: Suppose if you want to select AI Addresses start from 100 and No
of channels as 20. Just select Channel type as Input variable and enter
address text box 100 and in No of channels text box 20 and click on Set
button.

________________________________________________________________________ 9

________________________________________________________________________

Device Configuration:
This Device Configuration Property sheet consists of set of pages. The first
page consists of Device related configuration parameters. Users can display
this property sheet in any one of the following methods:
 By clicking on the menu item Configuration  Device & Communication
Settings.

 Clicking the Device & Communication Settings tool bar button

 Device ID: In this Device ID text box you can enter connected device ID
(number only).
o For MODBUS complaint devices these numbers are between 1 and
247.
 Poll Time: Enter the poll time in 100’s of milli seconds. Suppose if you
entered as 20 then once in 2 seconds it will scan the data from device.
 Time Out: Enter the timeout value in terms of milli seconds. This
configuration filed used while communicating with device.
 Enable Data Storage: With this check box you can either enable or
disable the data storage.
 Data Logging Interval: The data logging interval will be in terms of
seconds only. Support if your Poll time is 500 m.sec and Data Logging
interval as 10 seconds then the data will be stored once in every 20 scans.
These 20 scans will be used for alarm generation and monitoring purpose.
 Data Storage: In this radio buttons you can specify the data storage
interval. Once that interval is finished the data will be stored in a file and
the further data will be stored in different file.

________________________________________________________________________ 10

________________________________________________________________________

Protocol Configuration:
The second property page of the Device Configuration Sheet is the Protocol
Configuration page. In this property page you can select the communication
protocol for the connected device. In addition to this you can add/delete new
protocol drivers.

By moving the UP/DOWN arrows you can switch between different protocols.
Protocol related information will be displayed in the Communication Medium,
DLL Name and Protocol Description text boxes.
You can build protocol drivers for your custom devices. Those drivers you can
easily by clicking the add button. To build drivers we will provide driver
development wizard. Once you build the driver just copy that DLL to Drivers
directory within in you DA Package installation directory then you have to add
it to the existing Protocol driver list.
Users can easily find the Drivers directory in the Location Dialog. This dialog
is activated by clicking on the SettingsPaths menu item.
Once you click on the Add button the following dialog will be displayed. Here
you can add your interested name for your communication protocol driver and
this name will be displayed in the available protocol list. Then you need to add
DLL name. This DLL is required to copied into the Drivers directory. Then you
need to provide short protocol description and finally you need to select
communication medium type. To specify the communication medium type you
have the following options SERIAL, ETHERNET, OPC and OTHER.

________________________________________________________________________ 11

________________________________________________________________________

If your communication driver communicated with devices other then SERIAL,
ETHERNET, OPC like USB, GPIB, etc., then you have to select OTHER. If
you select OTHER you don’t get any kind of configuration dialogs all the
communication specific settings will be either hard coded in the driver it self or
you have to generate INI files and use them.
At present we are providing the configuration dialogs for SERIAL,
ETHERNET and OPC drivers only. In the future we can add the configuration
dialogs for USB, PCI, PXI devices also.

________________________________________________________________________ 12

________________________________________________________________________

Serial Port Configuration:
The third property page of the Device Configuration Sheet is the Serial Port
Configuration page. In this property page you can select the Serial Port. (At
present we are supporting maximum of 4 serial ports COM1 to COM4). You
can set each serial port configuration parameters such as Baud Rate, Parity,
Data bits, and Stop bits. The Serial port configuration dialog is shown in
below fig:

Note: For Modbus RTU protocol always set the Data Bits as 8.

________________________________________________________________________ 13

________________________________________________________________________

Ethernet Port Configuration:
The fourth property page of the Device Configuration Sheet is the Ethernet
Port Configuration page. In this property page you can set the IP Address
and IP Port no of your device. The configuration dialog is shown in below fig:

Note: For Modbus complaint devices the default port is 502.

________________________________________________________________________ 14

________________________________________________________________________

OPC Server Configuration:
The last property page of the Device Configuration Sheet is the OPC
Configuration page. In this property page you can select the OPC Server
either on local machine or over remote machine. Suppose if your server
resides on local machine (i.e., On the same machine where DA Package is
running). Then you can enter the remote machine name as local or 127.0.0.1.
If your OPC Server resides on remote machine then you can enter the remote
machine name or its IP address.
Once entered the Remote machine name just click on Get Servers button. It
will enumerate all the available OPC DA Servers installed on the specified
machine. In this servers list you can select Server and test for availability and
security related constraints.

________________________________________________________________________ 15

________________________________________________________________________

OPC Item Configuration:
In this OPC Item configuration dialog you can configure OPC Items on the
selected OPC Server. The OPC item configuration dialog is shown in below
fig:

In this configuration dialog you can see all the available Items on selected
OPC server will be displayed in Available Item On server Tree Control. Here
Items are arranged hierarchically the same way they are configured over
OPC Server.
Initially you need to specify group name that need to be create at OPC server
for your DA Package configured items. You can also specify the Scan Time,
Deadband and Read Data From options also.
You can select the Items by double clicking on any item in the tree control.
That Item full name will be displayed in the Server Item name text box. Then
you have to specify the channel type (i.e., AI, DI, AO or DO) also need to
select Data type. Then you need to specify Item name. This name is visible at
client side (i.e., you can’t see from OPC Server). Basically this name is an
alias for Server Item name. Finally you need to specify Start address and No
of channels. These address value should be within the range you specified in
the address configuration dialog.

________________________________________________________________________ 16

________________________________________________________________________

If you selected the Set as Tag Name check box Then this Item name is set as
Tag Name for that address.
Once clicked on Set Item button, the it will first adds this item to OPC Server.
If it is successfully added then this item will be added to OPC configuration
list. All the configured items you can find in the bottom list box.
Once configured the items you can modify or delete the items.

________________________________________________________________________ 17

________________________________________________________________________

Tag Configuration:
With this Tag Configuration Dialog you can set the Tag Name, Descriptive
Name, Engineering units (For Analog Channels Only i.e., AI & AO channels)
and ON Caption, OFF Caption (For Discrete Channel i.e., DI & DO channels).
Users can display this Tag Configuration dialog in any one of the following
methods:
 By clicking on the menu item Configuration  Tag Configuration

 By Clicking the Tag Configuration tool bar button

The Tag Configuration dialog is shown in below fig:

Channel Type: In this combo box you can find four different kinds of
channels Input Registers (AI), Holding Registers (AO), Input Discrete (DI) and
Output Coils (DO). Once you selected any one of the above channel types
then it will automatically update the Address list box and Tag description lists.
Address: This list box contains the all the channel addresses of the currently
selected Channel Type.

________________________________________________________________________ 18

________________________________________________________________________

Tag Name: You can set maximum of 10 characters Tag Name for each
channel in all channel types.
Example: Tag Name for any AI Channel BLR1_TMP, Similarly DI channel is
OPC_DI_TG1, etc.,
Descriptive Name: With this text box you can set maximum of 20 characters
descriptive name for all kind of channels.
Example: The Descriptive name for any of the channel is “ETHYLE AMINE
BLR TEMP”, “NITROGEN MIXTURE TEMP”, etc.,
Engineering Units: You can set the engineering units only for Analog
channels (AI & AO i.e., Input Registers & Holding Registers). This text box will
be enabled if you selected one of the Analog Channel in Channel type Combo
box.
New Discrete Caption & Discrete Caption: This Discrete Caption will be set
for only Discrete Channels (DI & DO i.e., Discrete Input & Output Coils). This
Combo box and text box will be enabled if you select one of the Discrete
Channel Type in the Channel type Combo box.
To add new discrete caption you need to enter the New Discrete Caption text
box like OPEN/CLOSE format. (Here OPEN stands for Boolean TRUE or 1,
similarly CLOSE is used for Boolean FALSE or 0). Once you click Add button
this new discrete caption will be available in Discrete Caption Combo box.
Now it is ready to select for any Discrete Channels.

________________________________________________________________________ 19

________________________________________________________________________

Analog Channel Configuration:
Analog Channel Property sheet consists of three property pages. All these
property pages are used to configure only AI (Analog Input or Input Register)
channels only. This configuration dialogs are used to set Maximum, Minimum
values, you can define various Alarm values and any Signal condition specific
settings.
Users can display this Analog Channel Configuration dialog in any one of the
following methods:
 By clicking on the menu item Configuration  Analog Channel
Configuration.
 By clicking the Channel Cfg button on the Front panel.

 By Clicking the Analog Channel Configuration tool bar button .
First property page in this Property Sheet is shown in below fig. Once you
selected any one of the AI channel then its Tag Name and Descriptive Name
automatically displayed these tag descriptions you can see from all three
property pages.

Auto Scale: If you check this check box, then Maximum and Minimum text
boxes will be automatically disabled. In trend view the Maximum and
Minimum values are automatically calculated at runtime from the collected
data. If any of the new data comes beyond the Max, Min limits then these
Max, Min values are automatically updates.
________________________________________________________________________ 20

________________________________________________________________________

Max Value: You can set the Maximum AI value for the currently selected AI
Channel. This text box is available if Auto Scale Check box is not checked.
Unlike Auto Scale mode this value can’t be updated at run time.
Min Value: You can set the Minimum AI value for the currently selected AI
Channel. This text box is available if Auto Scale Check box is not checked.
Unlike Auto Scale mode this value can’t be updated at run time.
Time Scale: This value will be used to specify the each trend screen size.
You can set different trend screen times for different AI Channels.
Display Indicators: These check boxes used to select the display indicators
in the trend view. These check boxes allow you to select only properly
configured alarms only. For alarm configuration you can find second property
page of this Analog Channel configuration Property sheet.
The Second Property Page in this Property Sheet is shown in below fig. With
this property page you can set Set Point and various Alarm values. In Auto
Scale mode you can’t set any of these Alarm values.
Before setting the Set Point and Alarm Conditions you need to set proper
Maximum and Minimum values for corresponding channel. You can set
different Set point and Alarm values for each channel.
The Select Configuration parameter Combo box allows you to select any one
of the configuration parameter. This SET POINT, HI HI alarm Value, Hi Alarm
Value, Lo Alarm Value & Lo Lo Alarm values should be within the Maximum
and Minimum values those are set in the first previous property page for the
corresponding AI channel.

 SET POINT
 HIGH HIGH ALARM VALUE (Alarm)
 HIGH ALARM VALUE (Warning)
 LOW ALARM VALUE (Warning)
 LOW LOW ALARM VALUE (Alarm)
 RATE OF CHANGE ALARM VALUE (Alarm)
From the above first five configurations you can set in two ways:
 Binding to Device Address: If you select Bind Configuration to Device
Address check box then the address text box will be enabled. In this text
box you need to specify the device AO (or Read write address) where the
configuration is defined. Once you entered the address if you click on Set
button then value will be read from the specified address from the
connected device. If the values successfully read then this particular
configuration is set other wise an Error message box is prompted and
configuration is not set.
Note: Before setting the configuration you need to make sure the package
is connected to the device and communication is established.
________________________________________________________________________ 21

________________________________________________________________________

 Directly Setting the Value: if Bind Configuration to Device Address check
box is unchecked then this text box will be enabled. In this text box you
need to directly enter the value for the corresponding configuration. These
configuration values should be within the Maximum and Minimum value of
the currently selected AI channel. After entering the value if you click on
the Set button then only that configuration is set.

If you select the RATE OF CHANGE configuration parameter ROC Text box
will be enabled and the remaining text boxes will be disabled. This text box
will take not only digital numbers you can enter float point values also. Once
you entered ROC value you need to click on Set button then only this
parameter is configured.
Note: This ROC value should be in between 0.01 and 100.00.
Note: Once you configured these configurations parameters and switch to
Auto Scale mode then you will lost the first five configurations. These
configurations will be invalidated in Auto Scale mode. If you switched back
from Auto scale mode to non Auto Scale mode you need to reconfigure
(Basically Set) the parameters.

The Third Property Page in this Property Sheet is shown in below fig. With
this property page you can set signal conditioning related parameters.
The first Signal Conditioning radio buttons, for Linear there is no change in
the Process Variable (PV or AI) value. It will be used the same value that got

________________________________________________________________________ 22

________________________________________________________________________

from device. In Square Root mode it will square roots the incoming PV value.
In the Log mode it will converts to logarithmic value.
In addition to above conversion you can make custom scaling by selecting the
Enable Custom Scaling check box. It can allow you to select only in Non-Auto
Scale mode only and you need to select the Linear Signal conditioning mode
only.
In the Raw Values check boxes you can enters Input variable range those
read from device, In the processed value you will get automatically Max and
Min values those entered in the fist property page of this Analog Channel
configuration. At runtime, every time acquiring the data this package
automatically converts Raw Value to Process Value.

Example: One of your channels you are configured its Raw values are 30
and 120 and Processed value is defined as 300 and 1500 (i.e., Maximum
and Minimum values set in the first property page). When you scan, if you got
the PV as 50 (i.e., Raw Value) then it will be converted as 566 (approx) as
process value.

Alarm & Event Configuration:
Alarm & Event Configuration Property sheet consist of 4 property pages for
each channel type (AI, DI, AO & DO). As per the process industry terminology
you can monitor three kinds of events.
ALARM: As the PV is moving from Normal condition to abnormal condition is
called as an Alarm.

________________________________________________________________________ 23

________________________________________________________________________

EVENT: If the PV is recovering from abnormal state to normal state is called
as EVENT.
MESSAGE: Any changes occur, you want to log those changes, you can
configure those changes as MESSAGE. Ex: If you want to change any of the
RO register or Activate any of the Coil of the connected device then you can
log these changes as MESSAGE.
Users can display this Alarm & Event Configuration Property sheet in any one
of the following methods:
 By clicking on the menu item Configuration  Alarm & Event
Configuration.

 By Clicking the Analog Channel Configuration tool bar button
For Alarm Beep related configurations, see the Chapter 7.2 Printer & Alarm
Beep related settings.
Analog Input (AI) Channel Alarm Configuration: Alarm configuration for AI
Channel is a two step process.
 In this first stage it required to assign valid HIHIAlARM, HIALARM,
LOALARM, LOLOALARM , ROC Alarm values for each from those you
want subscribe alarms.
 In the second stage you need to subscribe the required alarm conditions.
For AI channels you can find the following Alarm Conditions. As PV (Process
Variable or Analog Input or Read Only Register Value) Changing from:
 LT HI ALARM VALUE TO GT HI ALARM VALUE
 GT HI ALARM VALUE TO LT HI ALARM VALUE
 LT HI HI ALARM VALUE TO GT HI HI ALARM VALUE
 GT HI HI ALARM VALUE TO LT HI HI ALARM VALUE
 GT LO ALARM VALUE TO LT LO ALARM VALUE
 LT LO ALARM VALUE TO GT LO ALARM VALUE
 GT LO LO ALARM VALUE TO LT LO LO ALARM VALUE
 LT LO LO ALARM VALUE TO GT LO LO ALARM VALUE
 RATE OF CHANGE (ROC) ALARM
With the below AI Alarm & Event configuration property page you can
subscribe any one or all of the above alarm conditions. At the time of
subscribing the Alarm you can specify Alarm type can be any one of the
following ALARM, EVENT or MESSAGE.
Once Channel Address selected all the configured alarms are populated to
the bottom List control. Now you can subscribe new alarms or you can delete
any subscribed alarms.
At the time of subscribing the Alarms you can optionally enter any message
that can indicate Alarm specific information.
________________________________________________________________________ 24

________________________________________________________________________

For each subscribed alarm you can specify Control Action. This control action
will automatically perform whenever that particular alarm occurred. To define
Control Action first you need to select subscribed alarm for which you want to
define Control Action and just click on Control Action button. Then the
following dialog will display to define control action.

The control action can be Analog type or Discrete Type.
Analog Action: This type of control actions you can change any of the
Analog RW register (or Holding Register) value. Ex: If any of the Hi Alarm
occurred you can change any of the PID parameter values on the connected
device.
Discrete Action: For Discrete actions you can activate or deactivate any of
the Output coils (Discrete RW Register). Eg: If any of the alarm occurred you
can CLOSE the Fuel Valve. Whenever the Alarm recovered to Normal state
(i.e., EVENT occurred) then you can configure to OPEN it automatically.

________________________________________________________________________ 25

________________________________________________________________________

Discrete Input (DI) Channel Alarm Configuration: Unlike AI configuration
this is just one step process. You can find following types of alarm conditions
for DI Channels:
 ON TO OFF : DI value changed from 1 to 0.
 OFF TO ON : DI value changed from 0 to 1.
You can subscribe the above alarms conditions from the second property
page of Alarm & Event Configuration Property sheet. These alarm conditions
can be any one of alarm type ALARM, EVENT or MESSAGE.
DI Alarm & Event configuration property page is shown in below fig:

Like AI channels for each subscribed alarm conditions you can define Control
Action and these control actions are either Analog action or Discrete Action.
These actions are automatically executed whenever the alarm condition
occurred.
Analog Output (AO) Channel Alarm Configuration: For AO channels
(Holding Registers) also one step subscription for Alarm. For the AO Channel
there is only one type of alarm condition is defined:
 HR VALUE CHANGE
Whenever manually changing the AO Channel values (Holding Register)
values these alarms are generated. There is no Control Actions for these

________________________________________________________________________ 26

3. DA Views:
This Data Acquisition Package consists of 6 different kinds of screens. These
screens will help to present and monitor the data in various formats. User can easily
switch between different screens either by selecting the menu item or by clicking on
buttons available in various screens.

Front Panel:
This is the first and major screen in this Data Acquisition package. All kind of
channel parameters you can view from this front panel. The basic front panel
screen is shown in below fig:

In this Front Panel you can see two different kinds of Channels. The left set of
Channels is Read Write Channels (i.e., AO and DO) and the right set of
channels is Read Only Channels (i.e., AI and DI).
At the right side of this Front panel there are set of buttons. By clicking on
these buttons you can either pop up configuration dialogs are you can switch
to other screens.
The Start button is initially disabled. Once you loaded communication driver
and established the connection with device this button is automatically
enabled. How to establish a connection with device you can see “How to

Login Time. How to Add or Remove users please see Login User
Management Chapter.
With Load & Save buttons you can load the RW Register (Both Holding
Registers AO and Output Coils DO) values from the connected device
registers and you can save them to device registers.
To change any of the register value just double clicking on the corresponding
channel an Update Data Dialog will pops up. In this dialog you can change
the values and finally clicking on the Update button it will automatically
updates the corresponding channel value.

Finally you can save this value to the Device Registers by clicking on the
Save button. Before saving the values to the Device it required to need to
establish the connection with device.
Once you established the communications with devices and started acquiring
the data, the data will be automatically updated in the right side RO (Both AI
& DI) channels. These channels data will be updated in each scan.
If you want to scan only any one kind of channel per moment you can clear
the other type of channel Enable Check box. Once it cleared the
corresponding channels data is not going to be read from the device until it
will be checked.
If any of the AI Channel value crosses the alarm limits then the color of the
corresponding channel value will be changed to different color.
If the PV is above the HiHiAlarm or below the LoLoAlarm value then color will
be appeared as Red. Similarly if the PV is above the HiAlarm value and below
the HiHiAlarm value (Similarly Below the LoAlarm value and above the
LoLoAlarm Value) then the PV is displayed as Green. Within the normal
range it will be displayed as Black.
If no alarms are configured for any particular channel then the corresponding
channel value always displayed as Black.
