PROFESSINAL EXPERIENCE

Schneider Electric, CA Senior Programmer Analyst April 2013 till Date

Supervisory Platform Sustenance (MOL) - Wonderware Products.

An infrastructure for simplifying the development, deployment, maintenance, and administration of distributed automation applications. A new tier of real-time data acquisition, alarm and event management, data manipulation services, and collaborative engineering capabilities.The Wonderware Application Server is built on Invensys' Architecture by ArchestrA™, the comprehensive plant automation and information architecture that works behind the scenes of the latest Wonderware products. The Wonderware Application Server's underlying ArchestrA architecture facilitates the re-use of engineering, standardization, peer-to-peer connectivity, remote diagnostics and administration, source code control, and role-based data security. The purpose of the Supervisory Platform Sustenance Engineering project is to develop the service packs and patches needed for various Invensys PLC HMI\SCADA software products. Invensys Plc will specify the requirements of the service pack and patches that needs to be delivered by providing a project scope document. The various phases of the project include the requirements gathering, analysis of the requirements, design and implementation before the delivery. This project follows the various phases of a typical software development life cycle (SDLC). This project also delivers the single user products (SUPs) as needed by various customers of Invensys. Each service pack or patch also includes all the hot fixes that were delivered to the customers on a particular version of the software. Also the lab manager based on the VMWare technology is used in this project.

KLIDO(licensing Tool)

The purpose of Klido project is to present an approach for unified licensing to the customer to manage Invensys licenses of different vendors like Wonderware, Simsci, Avantis etc. The scope of the Unified licensing program as a primary objective to have all products uses the same licensing model. A Central System which maintains a license manager Tool which provides the specific licenses to the systems which are using the products in the system over a Network. Maintains different types of Licenses such as Local Licenses, Served Licenses. Local Licenses are directly copied to the systems through common shared folder which will be consumed by the product. Served Licenses are maintained in a system where the particular Server is installed(Ex: ArchestrA License Server, IPASSI FlexNet 11.8 Service), Named Users or Named Devices consume these licenses from the server. Installs/Uninstall license on Local node, Remote node. Depending on the number of different products, such licenses can be installed in the system through a Central System can also be called as Master node. Other License Managers can also be connected to this Master node as a client Node and can use the same data model and updates them. License Manager Master node shall communicate with a remote node in secure way for data exchange between master node and remote node. And License manager will have different views like System View, purchased view and license view. User should be able to configure License Manager as a Master Node or Client Node.

Field devices Using HART Protocol

Field devices team develops DTMs for Industrial devices used for configuring parameters like Pressure, Temperature, Flow etc. The Device Type Model (DTM) developed is tested through tools like Pactware, FdtContainer.

I have worked for the DTMs IMT96 (Flow device), I/A Pressure Device(Pressure Device).

I/A Pressure Device: IASPT Dtm works with the HART protocol. This DTM follows the rules and regulations of the FDT. And undergoes tests with the DTM Inspector. There are three revisions in the IASPT DTM which it supports. This software supports the Device type are IGP, IAP and IDP with all three available revisions. This component sits in a container application and allows configuring various device parameters. With the help of Graphical User Interface, device parameters can be displayed and also updated to the device.

IMT96 Device: The IMT96 device type manager is a high level configurator for the imt96 (magnetic flow transmitter) device. By using this software we can upload, update and download the device parameters. We can see the graphical representation of parameters. The IMT96 DTM is a hart configurator, which means it will work only with hart enabled imt96 device. This IMT96 DTM development strictly follows the (FDT JIG) DTM style guide and it is developed in such a way that, certified by the DTM inspector (a testing tool from M&M).

RTT80 Device: RTT80 HART devices are Temperature head transmitters with 2 input channels and HART® communication for the conversion of different input signals into a scalable, analog 4...20 mA output signal.

The RTT80 HART device stands out due to signal reliability, long-term stability, high precision and advanced diagnostics (important in critical processes) and for the highest level of safety, availability and risk reduction

It is usable for resistance thermometer (RTD), thermocouple (TC), resistance transmitter (Ω) and voltage transmitter (mV).

Responsibilities:

Coding, Bug fixing, Troubleshooting, Unit Testing and Integration Testing.

Implementing the features as designed in Visio.

Testing the application with DTM Inspector.

Used client supplied DTM Manager framework for the development of DTMs and followed HART

Communication Protocol (Highway Addressable Remote Transducer), FF(Foundation Fieldbus protocol).

Data is stored in the Device through the Front End Tool, DTM.

Interacted with business analysts in requirements gathering and analysis.

Frequent discussions with client and taking suggestions in development of Front End GUI

because the commands executed will interact with Firmware(device driver)developed at client end.

Followed Water Fall Model in development of the DTMs.

Resolving the customer issues as part of maintenance of old DTMs.

DTMs development is a Fixed Bid projects. Duration of delivery of DTM Projects is mostly 6 months,

and delivered to customer without penalty.

Comply with the SDL for the changes made.

Environment: C++, VC++, MFC, ATL Com, Visio, Sourcesafe, Windows XP, Multithreading, Synchronization Objects, DTM Manager, DTM Inspector(DTM – Device Type Manager), DD(Device Discription Language), Pactware Tool, FDT Tool, InstallShield .
