Industrial automation and PLCSCADA System

When an operator continuously read the process temperature and varies heating or cooling input so that the temperature is maintained to the set value, it it called manual control mode. In industrial automation, measurements & variations are done automatically on a continuous basis. Manual control may be used for non-critical applications where major parameter upset is unlikely to happen, where process changes slowly and where operator attention is not very much critical.

What is Industrial Automation ?

When products and manufacturing control is delegated to computers and PLC Systems, it is known as Industrial Automation. Manufacturing assembly lines as well as stand-alone machine , robotic devices come in this category.

What are the different components used in industrial automation?

• Field Sensors for sensing the parameters
• Transmitters for conditioning and converting raw signal into electrical signal
• PLC, DCS or PID based control systems
• Final control elements such as drives, actuators, , Solenoid valves, coils, control valves, Indicating lamps, hooters.

What are the different control systems used in industrial Automation?

• PID Controller based
• Programmable logic controller PLC based
• Distributed control system DCS based
• PC Based industrial automation system

A PLC an electronic device/industrial computer which performs discrete or sequential logic in manufacturing processes, assembly line, standalone machines. Initially PLC system was manufactured to replace mechanical timers, counters, relays. Today PLC systems are used successfully to achieve complicated control operations in a factory/plant. Purpose of PLC System is to monitor process parameters and achieve desired process operations. A sequence of instructions or PLC Program is developed by the user in PLC Programming software and placed into PLC memory. The purpose of this program is to operate PLC System such that desired manufacturing process results are achieved.

PLC System evolved from conventional relay based logics in early 70s. First time PLC system was used for automotive plants. Traditionally in auto plants those days, plants were shut down for a very long time whenever there was a change in model of the car or vehicle. PLC systems with the help of PLC Programming greatly reduced changeover time. Wiring of new or revised relay & control panels was so time consuming, it used to take months. The PLC programming replaced the rewiring of a panel full of wires, timers, counters, relays, & other components. The PLC system helped reduce the changeover time to a matter of few days.

PLC Programming

In PLC Programming, Programmer writes a set of instructions/ commands informs the PLC to complete the task.  Various types of PLC Programming languages are used but most user friendly and mostly used languages is Ladder diagram. This graphical language is near to general electrical symbols and easily understood by engineers.

• Ladder Diagram (LD): Mostly used PLC programming language which looks like a ladder..
• Functional Block diagram (FBD): PLC programming language that uses large function block for writing program.
• Structured text (ST): This PLC programming language, a series of steps and descriptions are used to write a program. Structure text uses a lots of IF, Else, and TRUE or FALSE notions.
• Instruction List (IL): This PLC programming language that consists of series of sequential statements to write a program.
• Sequential Functional Chart (SFC): This language uses vertical and parallel connected blocks and gates for PLC programming.

What is sourcing and Sinking in PLC system

When positive side of the power source is at Field devices, field device is source of power to the module, it is called sourcing. Field devices on the negative side of the power supply are sinking field devices. Generally Sourcing field devices are connected to sinking I/O cards and Sinking field devices to Sourcing Cards.

Ladder diagram

• Ladder diagram closely resembles to electrical symbols
• Ladder logic diagram is developed in PLC programming software.
• In electrical circuit the devices are described as on or off, where as in Ladder diagram, instructions are either TRUE or FALSE.
• Ladder Logic Program has at least one output and generally contains one or more inputs.

Hardly there are institutions which focus on practical aspects of PLC programming. Sofcon India Pvt Ltd in its fully equipped labs across the country imparts PLC SCADA training, PLC Programming courses in order to equip budding engineers with practical programming skills.

What is Scan Time in PLC Programming

In a PLC system, processor always scans the status of input devices, whether they are true or false.

Scan cycle in PLC is: reading the input, implementing the logic and updating the output. First the PLC checks status of each input if it is on or off. It records this status into its memory to be used during the next step. Then PLC executes the program. Suppose you have written a program which says when input 1 is high, switch on output1. Finally PLC updates the status of the outputs. After the third step is done, PLC goes back to the first step, thus repeating the steps continuously. Time take to complete one cycle is called scan time of the PLC. Generally the scan time of small PLCs is 1-2 milliseconds. In many fast moving manufacturing applications PLC scan time is very critical.

Latest micro controller MCU development boards

Embedded system design has never been so easy before. Today embedded system ecosystem offers easy access to development boards and most important feature is embedded software support. The prototyping scenario has seen an escalation and one of the biggest factors is the range of microcontroller (MCU) development boards out there in the market. From low cost micro controller development boards to powerful application specific ones, with new features things are available.

Quite a few development boards in the market are general Micro controller MCU specific, such as STM32 discovery kits, MSP430 from Texas instruments or Xplained boards from Atmel. Local companies design some of the economically available micro controller boards. In both cases MCU development boards come in two flavours; one is the MCU evaluation board, where the focus is on evaluating MCU Capabilities. Second category is application of feature specific, where the board is desingned for the purpose of evaluating certain features of the MCU and is usually focussed on some application area.

Broadly there are 3 different categories of Micro controller boards: Generic multi-purpose Boards; Today every MCU manufacturer like Microchip, NXP, Cypress, TI and Atmel provide and evaluation kit compatible with their microcontrollers. Manufacturers like Arduino, Sparkfun, Adafruit, Mikroelectronika are popular among students and professionals.

Development boards for Microcontrollers based on AVR, PIC, 8051 and ARM7 architectures are very popular among students and beginners as these are easily available in the local market. These come with a varying set of on board peripherals to suit a wide range of applications for every budget. MCU development platforms such as Arduino come with a host of free and open source libraries.

Application specific development boards: such boards are dedicated task oriented and mostly used by companies or engineers building specific products in areas such as home/industrial automation, automotive applications. These development boards allow to rapidly test the functionality of the microcontroller MCU as per the requirements before moving on to fabricating custom printed circuit boards.

Industry-ready development boards: advanced processing power boards based on ARM7 or ARM9 microcontroller architecture are used for industrial applications. These include cubietruck boards and dual core or quadrcore processors boards which are mostly used for media processing in applications like smart televisions, media centers and digital video recorders.

Different microcontrollers have varying features and the entire board is based on supported feature of the MCU. Primarily one looks at Microcontroller MCU boards for their processing and memory capability but nowadays most of these offer decent RAM and flash capabilities.

A Large Scope of Job in Engineer core fields are waiting ahead

Wonder the thing is, most people think that to get a job in Engineering design sector they’ll have to do Engineering Design Courses like AutoCAD, Solid Works & Catia. But the fact is Design Software knowledge is not for design field only. Most of the Manufacturing Department prefers the knowledge of design not just to make design, but to read as well. The engineer should have knowledge of 2D-3D design to deal with Production, IQC (Incoming Quality Control), FAQ (Final Assurance Quality), R&D (Research & Development) Departments.

An engineer who has 2D designing Knowledge may move towards different engineering sector too. For Example a Mechanical engineer who has 2D designing knowledge can deal with the Civil, Electrical & Electronics or more fields.

If we talk about Software specialization It depends upon the companys’ product. Solid Works & Catia both are 3D Design software. Now the first question is: which software to learn!

Don’t worry!!! Actually Catia is used for best surfacing and to make complex designs while Solid Works to make Simple part designs.

There are thousands of industries with thousands of vender companies having job vacancies for both the software, However industries prefer best programming skills holder or experienced ones.

Engineers studying or recently passed out from colleges lack the practical knowledge desired by such industry. Fresher just need to have a strong software platform, where they can fulfill the industry requirements, just need to vanish the gap between fresher and industry.

Government’s initiatives: Govt. has already achieved a great success in production of automobiles and planning to do well in future.

Third largest automotive market by 2016-2017.Four largest manufacturing hubs across the country:-East – Jamshedpur, Kolkata, West – Mumbai, Pune, Nasik, Aurangabad, North – Delhi, Gurgaon, Faridabad, South – Chennai, Bengaluru, Horus. Fifth largest passenger and commercial vehicles manufactures. Six million plus Hybrid and Electric vehicles to be sold by 2020 per year.Seventh largest producer with production of 24 million vehicles.

Carrier Scope: Suzuki (Japan), Nissan (Japan), Piaggio (Italy), Volkswagen (Germany), Renault (France), Hyundai (South Korea), General motors (USA), BMW (Germany), Ford (USA), Toyota (Japan), Larsen & Toubro, Jindal Steel works, Machino Plastic, UNO Minda, Imperial Auto pvt ltd, Bosch, Bhushan Steels, Vacmet India ltd, Motherson.

This sudden development has generated a huge demand for Design Engineers in Mechanical, Electrical, Electronics and Civil Sector.

How local chip manufacturing can transform electronics industry

With the government approving semiconductor fabrication plants, the electronics manufacturing ecosystem and the electronics industry as a whole will feel the direct impact of local production, the Indian economy will also benefit from it. A fab is estimated to contribute 23 times the investment made to GDP. Its transformative effect on the electronics industry is tremendous, and has a stronger multiplier effect than any other industry. Hence, it is a highly strategic game changer for India that will enable the country to leapfrog ahead by several years

The Indian electronics hardware industry and the Indian economy will directly benefit from the proposal. The semiconductor wafer fabs will have a catalytic impact on the development of downstream and upstream products, including ancillaries. They will also have a sizable impact on the development of the IT/ITES sector, particularly in very large scale integration (VLSI) design software, solutions and services. Besides, these fabs will help generate employment for 28.3 million (directly and indirectly) people by 2020, across various levels of competencies.”

 

Critical for the electronics industry

The fact that India’s semiconductor market makes up 14 per cent of the country’s total electronics market indicates the magnitude of the opportunity lost due to the absence of local fabs. They are at the core of ecosystem development and this strategic move shall have a ripple effect across the ecosystem. Global analysis shows that countries like Taiwan, China and USA have been able to build a fairly strong electronics ecosystem by setting up semiconductor fabs and using them as the moot point for bringing in the other ecosystem components.

Domestic consumption of electronics is expected to reach US$ 400 billion by 2020, which translates into a chip market of around US$ 55 billion. The total semiconductor market in India was $6.03 billion in 2011 and is expected to grow to $9.7 billion by 2015. Right now, India imports over 65 per cent of its electronics products, including semiconductors.

India has already become the hub for semiconductor design. More than 20,000 engineers are engaged in various aspects of chip design and verification. India adds value by way of design, which accounts for a modest $10 billion. Ironically, chips that are manufactured outside India, mainly by the Asian countries, are based on the design work done in India. These chips eventually go into finished electronics goods that are worth more than $60 billion. The semiconductor manufacturing companies abroad generate revenue to the tune of US$ 15 billion from wafer manufacturing based on these designs. Chip packaging and testing companies also generate US$ 5 billion revenue based on the wafers manufactured from the India-designed chips.
