Messung Industrial Automation

PLC Manufacturer in India

Leading Indigenous Plc Manufacturer In India: Messung

Whether we look at the Automotive or Food industry, Power or Sugar, Cement or Textile, Paper or Sewage Treatment – we see that most industrial processes and machines today are automated, and that the level of automation keeps growing. Modern industrial automation systems are smarter and more advanced than ever before.

Industrial automation is all about PLC. It is the PLC that provides the power and ‘intelligence’ of smart automation systems. PLC stands for programmable logic controller. It is a specialised computer control unit that automatically controls the different processes, devices and components in an industrial system, and makes decisions based on a custom programme. The application of PLC in industry is infinite.

Plc Pioneer

Did you know that in India, the first company to build PLCs was Messung Systems? Yes, it was way back in the early 1980s. Established in Pune, it was the first PLC manufacturing company that launched the country’s first PLC in 1984.

Today, so many decades later, Messung continues to rank amongst the top 10 PLC manufacturers and leading industrial automation companies in India, with PLC brands that have proven themselves in thousands of installations across applications and industries, all over the country. Messung’s integrated solutions with PLC programming for industrial automation as per specific customer requirements, makes Messung the preferred PLC manufacturer in almost every industry vertical.

Let’s go back in time to the period when Messung was founded and trace its eventful journey.

The Evolution of The PLC In India

In those early days, automation of industrial machinery was usually done using electro-mechanical contactors that created logical interactions by using the NC/NO contacts and electrical wiring to achieve logical decisions and interlocks. There were no PLC manufacturers in India to give solutions to machine manufacturers.

In the 1980s, the first few varieties of PLCs were launched. The early PLCs had a minimum “set of instruction”, and mainly covered logical functions like ‘And’ ‘Or’ ‘store output’ ‘load’ and ‘complement’ functions that were used to create simple ladder diagrams which were easy to understand by electrical control engineers.

In the mid-80s, microprocessor-based PLCs were developed, based on the Zilog-80 and Intel micro-processor based eight-bit technology. The simple ‘instruction set’ now had ‘word’ functions including ‘move’, ‘compare’, ‘greater than’, ‘less than’ along with simple mathematics, software timers; counters were possible.

One could also achieve functionalities like simple PID controls, replace ‘Drum wheel’ controllers, Sequence timer functions. More complex automation applications could be done with proper automation functions and interlocks including Arithmetic calculations e.g.

  • Electroplating plants
  • Painting lines
  • Sugar Centrifuge
  • Boiler and Heat treatment applications

Messung: Four Decades of Technology Development

In 1981, Messung was founded, and began developing a prototype Programmable Logic Controller (PLC) in a humble garage. Within a couple of years, Messung launched Meprolog-H, India’s first indigenous PLC. It was a 1-bit processor-based PLC, and in 1984, the first one was installed at Kirloskar Oil Engines, Pune.

In 1986, Meprolog-H won the G.S.Parkhe Award and FIE Foundation Award for Best Product Design, and in 1988, Farook Merchant, the founder of Messung, received the National Award for Outstanding Entrepreneur. The following year, Messung launched XMP8-40*, the first 8-bit microprocessor-based PLC which went on to achieve 6000 installations.

The following decade saw Messung continue on its journey of indigenous innovation. In 1992, XMP8-20* PLC was designed for smaller, compact machines, and installed in 12000 projects. Three years later, XMP8-10*, the ‘small wonder’ was launched and used in 25000 installations.

In 1996, Messung won the International WISITEX Award and Award for Excellence in Electronics by Govt. of India – achievements that only fuelled Messung’s passion for innovation. In 1998, NEXGEN 4000* PLC was designed in modular structure – and went on to win the FIE Award for Best Product Design.

In 2001, the NEXGEN 5000* PLC based on IEC 61131-3 standards was developed and in 2008, the NEXTO* PLC was developed. The next year, NEXGENIE* PLC was launched. In 2017, Messung launched the advanced NX-ERA series of PLCs for Industrial Automation.
