Welcome to the New-Era of Business with GST Roll-out wef: 1st July-2017!!
Effective from 1st July 2017, INDIA is poised for a great leap in day to day Business practices with the implementation of this historic Act, thus arriving at a consensus of
“ONE-INDIA, ONE-PRODUCT, ONE-PRICE “.
The input costs in manufacturing and trading needs to be carried throughout the Supply Chain and eventually taxed at the point of consumption.
The MSMED sector in INDIA will witness a sea change in activities and all need to be geared up soon to catch and keep pace in Business.
GST will be levied on all transactions such as sale, transfer, purchase, barter, lease, or import of goods and/or services. India will adopt a dual GST model, meaning that taxation is administered by both the Union and State Governments. Transactions made within a single state will be levied with Central GST (CGST) by the Central Government and State GST (SGST) by the government of that state. For inter-state transactions and imported goods or services, an Integrated GST (IGST) is levied by the Central Government. GST is a consumption based tax, therefore, taxes are paid to the state where the goods or services are consumed not the state in which they were produced. IGST complicates tax collection for State Governments by disabling them to collect the tax owed to them directly from the Central Government. Under the previous system, a state would have to only deal with a single government in order to collect tax revenue.
Goods and services tax (GST) will subsume various indirect taxes including central excise duty, services tax, additional customs duty, surcharges, state-level value added tax and Octroi. Other levies which are currently applicable on inter-state transportation of goods are also likely to be done away with in GST regime
I welcome one and all to contibute to the task of Nation Building thus truly bringing the slogan “ SAB KE SATH SABKA VIKAS “ a reallity in the days ahead.

Fare-well Message to S-8 students of SIMAT !!
It was nice to see you at the campus the other day.
Life is limited; do not waste your time living other’s life. Do not let the noise of other’s opinion drown your inner voice. Have the guts and courage to follow your heart and intuition.
You are not going to get far ahead in life with what you already know; it was what you learn after you leave this campus that will take you far ahead. You must have learnt several subjects (38-40 Engineering Papers etc , but this will all become dry incipit information if you do not reflect on them / re-learn and unlearn these practices.
Knowing and not acting on what you know is equal to not knowing.
Turn your existing knowledge towards devotion by constant practice to serve yourself and surroundings for the better.
Never Never give up trying. There is no such thing as FAIL : It only means First Attempt In Learning , nor there is any END : It only means Efforts Never Die. Think positive, if someone says NO, it only means there is a Next Opportunity.
In life it is always that small decisions are taken from your Head and big decisions always from your Heart.
In brief I want you all to become a better person and prosper well in life. To achieve this you must constantly work on your five inner KOSHAS “ defined as below in the Taittriya Upanshad “
1> Annamay Kosha < Food sheath >>> The food that you take determines the thought that you think.
2> Pranamaya Kosha < Energy sheath >>> All life manifest in breathing. Practice breathing exercise.
3> Vijnamaya Kosha < Wisdom sheath >>> Turn your knowledge towards devotion in action.
4> Manomaya Kosha < Mind sheath >>> Control your mind dynamics. As you think so you become.
5> Anandamaya Kosha <Bliss sheath >>> Experience joy and bliss in all walks of life. Be cheerful always.
Get up in the early hours of the day and try to become a 05 AM man, exercise for 20 minutes which will keep you fit and active the whole day .Also have control of the first thought of the day and the last thought of the day (before sleeping), doing so you will have control of the whole day and not that the day controls you.
Practice Frugal Engineering methods at your home and work place!!
HARI-OM & may GOD bless you in your pursuit.!!

Introduction
In the current highly competitive business environment, the industry is challenged by the demand for productivity, quality, safety and environmental protection.
Tight profit margins and networked manufacturing emphasis the need for integration and global optimization of production facilities. The role of information technology in achieving these goals has become critical. Large and complex production systems cannot be efficiently and safely managed without advanced information management and process control. End users expect to get improved functionality at reasonable cost. Management of knowledge and real-time information, integration with condition monitoring and plant maintenance, high availability, flexible upgrades and life-cycle support are examples of key requirements. System integrators need efficient tools for building applications. Manufacturers face the challenge of satisfying customers’ needs while still maintaining a sound and profitable product structure in a rapidly changing technical and business environment.We can expect that a similar situation will exist in the future also. Increasing processor power, consumer electronics, mobile communication networks and programming languages provide the tools to implement smart functions that have been unrealistic before.
Meanwhile, recent advances in the control domain have grown upwards from low-level programming languages and communication standards in the direction of more comprehensive data models and reference architectures. The increasing degree of horizontal and vertical integration leads to complex applications, which, in turn, calls for more powerful communication and computation models in control systems.
INFORMATION TECHNOLOGY
Mobile communication Home automation Consumer electronics Networked manufacturing systems
So, our working hypothesis has been that next generation control systems will be a combination of new information technology and the domain-specific concepts found in process automation and operations management. The focus has not been on hardware issues but rather on functional concepts related to applications and system software of control platforms. Therefore, the programming models and architectures used in software engineering have had an important role in the emergence of our future visions.
1.1 Scope and intended audience
The application area of the report is primarily industrial automation, including both process industries (continuous and batch) and discrete manufacturing. In addition, similar applications in other areas have been kept in mind. These include, e.g.,
Environmental monitoring and distributed energy production. While the term “automation” in general has a wider scope, it refers here to rather low-level monitoring control of equipment and production processes. A control system is a collection of distributed devices and software interconnected by means of a communication network.
It typically performs functions like process monitoring and control, management of production operations and reporting. However, it is recognized that control systems must be integrated with higher-level business and service applications.
Recent trends in automation are characterized by geographical distribution and functional integration. On the technical level, the goal is to easily connect devices and software components from different vendors. Functionally, there is a need for interoperability of control functions on different hierarchical levels ranging from field equipment to Enterprise Resource Planning (ERP). Many customers already use, within certain security limitations, web-based “thin” clients for on-line knowledge management, remote monitoring and maintenance. Future systems will be based on an even stronger distribution to the field level, on mobility, and on co-operation with components in distant locations.
As this report is an outcome of a research project, the main focus lies on concepts and generic system architectures. The aim is to discuss recent technological trends and to outline a new, component-based control system platform on the basis of identified application requirements and enabling technologies. However, the authors hope that it is useful to practitioners and automation students, as well. To achieve this, current trends and new implementation technologies in industrial automation have been described
1. Trends in industrial automation
The purpose of this chapter is to introduce the key problems and requirements. The domain covers the monitoring and control of various processes and devices in the industry and public infrastructure. Applications are related to automation of manufacturing systems and environmental monitoring, for example. All these are characterized by local and geographical distribution and integration with company-level information systems.
1.1 Changes in the business environment
Industrial products, such as chemicals, publication papers or mobile phones, are becoming more complex and have higher added value than before. At the same time, the number of product variations increases and their life time gets shorter. For years, Western countries have focused on high technology and moved bulk manufacturing to countries with lower labor costs. During the last decade, changes in the political situation and the economic development have accelerated the emergence of global markets. The growing markets in Far East and South America, for example, have created a situation where the manufacturing of high-tech products, and even parts of related R&D functions, are re-located close to major market areas. Tight competition and the increasing amount of societal regulation underline the importance of product quality, safety and environmental protection. The economics of scale and the expertise required in the manufacturing of complex products have led to co-operative networks of companies specializing in certain technologies or manufacturing operations. Along with globalization, these networks expand from domestic to international co-operation.
These trends in industrial production have their implications for companies that develop and manufacture the required production facilities, such as process equipment, paper machines or diesel generators. Firstly, deliveries often go to foreign countries. The project staff must be able to co-operate with many other suppliers and contractors from various cultures. Secondly, customers need extensive support in the operation and maintenance of those complex systems. For other than big manufacturers, establishing an office close to the customer is too expensive. Unfortunately, outsourcing the services to a local operator may also be difficult because of the expertise needed, or because of the intellectual properties that must be protected.
Monitoring and control systems are basic ingredients of efficient, flexible and reliable production systems. Traditionally, monitoring and control applications have been purchased as separate systems and adapted to their operating environment on a case-by- case basis. There have been companies specializing in dedicated hardware and software products without necessarily having much knowledge about their application domains.
Recently, understanding the customer’s business and manufacturing processes has become more important. In spite of the increasing computing power and lower hardware cost, developing and maintaining complex computer-based products is very expensive. This has led to acquisitions and fewer but bigger players in the market. Instead of starting from scratch, existing commercial solutions, such as PC hardware, operating systems and databases, are used whenever feasible. Partly influenced by the ongoing standardization, the current Distributed Control Systems (DCS) and Programmable Logic Controllers (PLC) in the market are rather similar in their capabilities.
This trend has emphasized the role of application knowledge and customer service, whether the system is supplied by the original platform manufacturer or by an independent system integrator. The customer expects to get solutions rather than hardware and software. As a result, system suppliers shift their focus from individual projects to application expertise, extended after-sales services and strategic partnership with their key customers.
In addition to control system suppliers, information technology has become a critical issue for manufacturers of production equipment. These machines or processes are often very complex, possibly even safety critical, and cannot be efficiently operated without automatic control. The know-how required for the operation and maintenance of these systems is a critical competitive factor for the equipment manufacturer, whether it is provided in the form of operating instructions, system specifications, control software, or as an actual control system embedded in the machine itself.
To summarize, control system suppliers must be able to implement more intelligent and reliable applications in shorter time and with lower cost in a global, multi-cultural environment. These remote systems must be maintained and upgraded according to changing production requirements. The business in basic data acquisition and process control has matured and is now growing rather slowly. Therefore, new opportunities are looked for in improved customer service and enhanced application functions.
Intelligent machines
The increasing number of product grades and grade changes, combined with the demand for high availability and rapid reconfiguration, emphasizes the need for flexibility in plant operation. To make this possible, the manufacturing equipment should be seen as intelligent resources capable of performing multiple tasks in co-operation. While the initial prerequisites are determined by process and mechanical engineers, the control system has a key role in putting the inherited potential into practice.

For many years, integrated, intelligent and dependable control systems have been the focus of standardization organizations, industrial consortia and research groups. The solutions have, however, been hard to reach, partly due to the complexity of the issue and partly because of conflicting commercial interests. Only few efforts have provided practical results about common architectures and application objects that could make systems really “understand” each other. Technically, open control systems still focus on ways of making bits and bytes flow between devices from different vendors. There is also a gap between research results and real-life applications. Instead of elegant control theories, practical automation projects often struggle with low-level technical problems. Important issues are, for instance, how to find out user requirements, how to interface different products, and how to reuse existing application software.

Instead of elegant control theories, practical automation projects often struggle with low-level technical problems. Important issues are, for instance, how to find out user requirements, how to interface different products, and how to reuse existing application software.
