Development of ActiveX controls for HCI in Industrial Automation – One of the
focus areas of Bells
We have a Sole Developer relationship with a leading Industrial Displays
manufacturer in Europe.
 developed more than 40 controls for Visualisation Controls
Meter, Symbol, Label, Bar, Selector, Trend, Profile etc.
 developed back end Controls for Data Acquisition, Alarm Management,
Operator Action management etc.
Some of the salient features of these controls are
 developed in VC++ using MFC/ATL
 for Windows CE, NT, 2000 and XP platforms
 support dual interfaces
 support full transparency i.e. see through a dynamically changing background
 compatible with .NET based client applications also

 Display format conversion class
This system takes input data from the PLC, which is connected through serial port. It converts these data to a string
as per IEEE 754 format (only for Real and Scientific notation) or BINARY format or ASCII format and display the
converted string in a palm device
 PDA Inventory Application.
The requirement was for user to collect data from the field place using HH and transfer data to the remote database.
The Main objective of this system is to sync (full duplex) a database between a handheld and a PC (SQL SERVER).
We have designed and developing a MFC conduit (dll) using Palm OS CDK toolkit.
Developing a front end in Palm OS to edit, view and delete records in handheld database.
 Logic Developer –PDA (LDPDA)
This application is developed to handle PLC data in the Palm Handheld.
LDPDA handles data from various Process Control applications like PROCESS 90, Logicmaster and CIMPLICITY.
These applications get data from the PLC unit and write it in the SNF (Shared Name File). SNF format is an
extension of the industry-standard Comma Separated Variable (CSV) format.
 Impact 'S-type' link
This project is to achieve a data link between a PalmOS and Impact's link interface computer on CD Net 2. The
Palm OS can send and receive messages to and from the Impact Moisture, Caliper, & Weight systems through a
single link interface. For sending and receiving we are using the IPMACT system’s handshaking protocol.

Bells & RTOS
RTOS ENHANCEMENTS FOR AN US BASED RTOS COMPANY
The RTOS has been designed to co-exist with various versions of Windows Oses. This provides
the required RTOS capability to windows platforms. Bells had carried out various enhancements
to this RTOS.
1. Porting of TCP/IP onto the customer’s RTOS
2. Porting of RTOS onto different service packs of NT/win 2000
3. Porting of RTOS onto Windows XP
4. Development of ODI driver on RTOS- The RTOS did not have support to DMA
devices. Bells developed a driver with this support for Intelpro100 ethernet card on
PCI bus.
5. Ported NE2000 driver from DOS to RTOS.

Bells & Embedded Systems
 High Speed Protocol Conversion for flight testing
Data from cockpit on four channels are combined on a predetermined format and are sent out as two-biphasic signal for recording, replaying and future
analysis.
 Speed and Altitude Monitoring for unmanned aircraft
Two non linear analog signals, one for Altitude and the other one for Speed are linearised and retransmitted as analog signals to the cockpit controller for
recording, indication and control. The module, which uses this software, is used in an unmanned aircraft.
 Precision Measurement & Image Processing
This is a PC based precision measuring software tool used in Standard precision tool rooms. This receives the displacement in x and y-axis in the form of
pulses from the job table through the glass scales. This s/w performs lots of trigonometric operations on the inputs provided to measure the dimensions of
the jobs accurately to the precision of 1.0 micron or 0.1 micron. The s/w has also graphics features and will also generate suitable files for AutoCAD or
CNC.
 Distributed Data Acquisition system
This PCbased front-end software acquires data through a PCI module. The handshaking and data transfer between the module and the CPU takes place
through a dual port memory. The data is collected at regular interval through the interrupt and stored in database. The software also provides MMI, setup
features for each channel, alarm setting, display and graphical representation of continuously varying parameters and report generation.
 Auto do outer ball groove classifier
This is an integrated setup consisting of an Industrial PC, Stepper motor drive, stepper motor, six LVDT probes along with the driver modules, proximity
switches and a control panel assembly. The application was developed using VB 6.0 with MS ACCESS as the back end. This application will run on win
9x or NT Platforms
 Error proofing based on vision technology
This application is also for an automotive parts manufacturing company. This consists of digital cameras, frame Grabber modules and mechanical
setup with necessary lighting arrangement. The software tools used are LAB WINDOWS and IMAQ VISION.

Configuration editor.
The configuration editor (used to configure display panels through RS-232 port) was converted from 16bit version( developed using version 1.5 of VC++) to a 32-bit version.
Though porting the code on to 32 bit was one of the options, based on client’s needs the s/w was
rewritten. The 32-bit was be developed in VB(Visual Basic) and VC++.

2 Payload checkout software
The software works on Unix systems. The same was rewritten to function on NT systems. The package helps
evaluate the performance of Remote Sensing Payloads of a satellite and the user has the flexibility of adding
and configuring any new remote sensing payloads by properly defining the required parameters as databases.
The main functions of software was :
 Data Processing, which includes auxiliary and video data collected by the special hardware for remote
sensing payloads.
 Generation on the processed data.
 Presentation of processed data and results in a graphical manner.
 Batch processing of various utilities to reduce user interaction.
 Archiving and retrieving of payload data for future
