What is PLC/SCADA/DCS ?

PLC is a programmable Logic controller which is used mainly for interlocking different equipments.

DCS is Distributed Control Systems which is used to control very big plants by using simple GUI screens. PLCs are interfaced with DCS for interlocking.

SCADA is Supervisory Control and Data Aquisition which is used to control and Monitor small number of Equipments in a field.SCADA systems are typically used to perform data collection and control at the supervisory level. Some systems are called SCADA despite only performing data acquisition and not control.The supervisory control system is a system that is placed on top of a real-time control system to control a process that is external to the SCADA system (i.e. a computer, by itself, is not a SCADA system even though it controls its own power consumption and cooling). This implies that the system is not critical to control the process in real time, as there is a separate or integrated real-time automated control system that can respond quickly enough to compensate for process changes within the time constants of the process

PLC & SCADA Based Industrial Automation 

The systems are based on different programming software including Visi- Windows, Genesis and Intellution. These systems helps in making the process automatic without any human intervention that in turn also eliminates the possible human errors. The automation of systems makes the whole process accurate with less material wastage and consistent product quality. 

The process data is recorded continuously batch wise, line wise and equipment wise and can be shared by using SQL ERP System. This data helps in conducting yield analysis, production rate productivity and material & manpower usage. It also send text messages to the concerned staff in critical situations. It is managed using Distributed Computing architecture (DCS).

What are microcontrollers and what are they used for?

Like all good things, this powerful component is basically very simple. It is made by mixing tested and high- quality "ingredients" (components) as per following receipt:

• The simplest computer processor is used as the "brain" of the future system.
• Depending on the taste of the manufacturer, a bit of memory, a few A/D converters, timers, input/output lines etc. are added
• Simple software able to control it all and which everyone can easily learn about has been developed.

On the basis of these rules, numerous types of microcontrollers were designed and they quickly became man's invisible companion. Their incredible simplicity and flexibility conquered us a long time ago and if you try to invent something about them, you should know that you are probably late; someone before you has either done it or at least has tried to do it.

The following things have had a crucial influence on development and success of the microcontrollers:

• Powerful and carefully chosen electronics embedded in the microcontrollers can independently or via input/output devices (switches, push buttons, sensors, LCD displays, relays etc.), control various processes and devices such as industrial automation, electric current, temperature, engine performance etc.
• Very low prices enable them to be embedded in such devices in which, until recent time it was not worthwhile to embed anything. Thanks to that, the world is overwhelmed today with cheap automatic devices and various “smart” appliances.
• Prior knowledge is hardly needed for programming. It is sufficient to have a PC (software in use is not demanding at all and is easy to learn) and a simple device (called the programmer) used for “loading” ready-to-use programs into the microcontroller.

COMPUTER TRAINING COURSE- MAINFRAME

What is mainframe computing?

Mainframe computing is the evolving general purpose computing platform incorporating the essential functionality required by its target applications. This technology is used for preparing critical accuracy driven computing applications. These are powerful computers used for bulk data processing such as census, industry and consumer statistics, enterprise resource planning, and transaction processing. The term originally referred to the large cabinets that housed the central processing unit and main memory of early computers. Later, the term was used to distinguish high-end commercial machines from less powerful units.

Most modern mainframe design is not so much defined by single task computational speed resulting in high reliability and security, extensive input-output facilities, strict backward compatibility with older software, and high hardware and computational utilization rates to support massive throughput. These machines often run for long periods of time without interruption, given their inherent high stability and reliability.

Nearly all mainframes have the ability to run (or host) multiple operating systems, and thereby operate as a host of a collective of virtual machines. In this role, a single mainframe can replace higher-functioning hardware services available to conventional servers. While mainframes pioneered this capability, virtualization is now available on most families of computer systems

Mainframes can add to system capacity without disrupting system function, with specificity and granularity to a level of sophistication not usually available with most server solutions.

Why Mainframe Computing?

Mainframe technology is a kind of niche and highly applicable computing for very huge and critical applications which otherwise would be very time consuming.

Mainframes are designed to handle very high volume input and output (I/O) and emphasize throughput computing. It is return on investment (ROI), like any other computing platform, is dependent on its ability to scale, support mixed workloads, reduce labor costs, deliver uninterrupted service for critical businessapplications, and several other risk-adjusted cost factors.Mainframes also have execution integrity characteristics for fault tolerant computing.

All applications which needed assured integrity such as financial transaction processing are wrun through mainframes only.

One of the most striking elements of mainframe computing, is the extent to which the architecture changes to accommodate user requirements.

In addition it also provides maximum I/O Connectivity  and maximum I/O Bandwidth in comparison to other computer systems.

In summary, the essential characteristics of a mainframe are: rapid and continuing evolution, general purpose orientation, hardware implemented solutions, and the criticality of user input to all of these processes.

Scope/Applications of mainframe computing 

• Performing large-scale transaction processing (thousands of transactions persecond)
• Computing census data
• Computing highly accurate applications
• Managing huge volume of data
• Support thousands of users and application programs concurrently accessingnumerous resources
• Managing terabytes of information in databases
• Handling large-bandwidth communication

Eligibility

Any undergraduate can learn main frame computing but it needs a knack for it because it is a rare computing technology.

COMPUTER TRAINING COURSE- LINUX

Source:- Freshersworld

What is Linux ?

Linux is, in simplest terms, an operating system. It is the software on a computer that enables applications and the computer operator to access the devices on the computer to perform desired functions. The operating system (OS) relays instructions from an application to, for instance, the computer's processor. The processor performs the instructed task, then sends the results back to the application via the operating system.

Explained in these terms, Linux is very similar to other operating systems, such as Windows and OS X.

But something sets Linux apart from these operating systems. The Linux operating system represented a $25 billion ecosystem in 2008. Since its inception in 1991, Linux has grown to become a force in computing, powering everything from the New York Stock Exchange to mobile phones to supercomputers to consumer devices.

Why Linux ?

As an open operating system, Linux is developed collaboratively, meaning no one company is solely responsible for its development or ongoing support. Companies participating in the Linux economy share research and development costs with their partners and competitors. This spreading of development burden amongst individuals and companies has resulted in a large and efficient ecosystem and unheralded software innovation.

Over 1,000 developers, from at least 100 different companies, contribute to every kernel release. In the past two years alone, over 3,200 developers from 200 companies have contributed to the kernel--which is just one small piece of a Linux distribution.

Where is Linux?

One of the most noted properties of Linux is where it can be used. Windows and OS X are predominantly found on personal computing devices such as desktop and laptop computers. Other operating systems, such as Symbian, are found on small devices such as phones and PDAs, while mainframes and supercomputers found in major academic and corporate labs use specialized operating systems such as AS/400 and the Cray OS.

Linux, which began its existence as a server OS and Has become useful as a desktop OS, can also be used on all of these devices. “From wristwatches to supercomputers,” is the popular description of Linux' capabilities.

The Future of Linux :

 Linux is already successful on many different kinds of devices, but there are also many technological areas where Linux is moving towards, even as desktop and server development continues to grow faster than any other operating system today.

 Linux is being installed on the system BIOS of laptop and notebook computers, which will enable users to turn their devices on in a matter of seconds, bringing up a streamlined Linux environment. This environment will have Internet connectivity tools such as a web browser and an e-mail client, allowing users to work on the Internet without having to boot all the way into their device's primary operating system--even if that operating system is Windows.

At the same time, Linux is showing up on mobile Internet devices (MIDs). This includes embedded devices such as smartphones and PDAs, as well as netbook devices--small laptop-type machines that feature the core functionality of their larger counterparts in a smaller, more energy-efficient package.

The growth of cloud computing is a natural fit for Linux, which already runs many of the Internet's web servers. Linux enables cloud services such as Amazon's A3 to work with superior capability to deliver online applications and information to users.
