I've been digging through industrial automation parts lately, and one name keeps coming up over and over again: Yaskawa. If you work anywhere near a production floor, robotics line, or CNC shop, you've probably run into their servo motors, drives, or Motoman robots at some point without even thinking twice about it.

Here's the thing that surprised me a little. Yaskawa isn't some new trending brand. It's been around for over a century, and that's exactly why it's still one of the most searched names in electromechanical parts today. So much of their equipment was built to last for decades, which means facilities all over the world are still running machines with Yaskawa servo amplifiers, AC inverters, and motion controllers installed years ago. When one of those parts finally wears out, someone has to go find an exact replacement, fast.

That's really the story behind the search demand. It's not hype, it's just a massive installed base of equipment that keeps needing support.

A few things I've learned are worth knowing if you're ever in the position of sourcing Yaskawa parts yourself. The part number and revision matter a lot more than people expect. Two components can look identical on the surface but have different firmware versions or connector layouts, and that mismatch can cause headaches on the line. It's also worth asking whether a part is new, refurbished, or a tested pull, especially with older Yaskawa models that aren't in regular production anymore.

And if the part you need is for something older, like a legacy Varispeed drive or an early servo model, a specialized distributor is usually a much faster route than trying to track it down through general channels. Facilities dealing with downtime don't have the luxury of waiting days for someone to confirm stock.

Before you can make an informed decision about whether or not this is the right choice for your company, you should know the fundamental impact that they could have on your production lines, so you must purchase a Rexroth servo drive online.

Why do you need them?

Servo drives from Rexroth have the potential to improve the efficiency and productivity of your manufacturing unit. Not only is the cycle time reduced, but also the overall costs.

The main reason you need to invest in servo motors by Rexroth is that they are highly efficient. They tend to run much smoother than other systems, which results in lower energy consumption and increased production speeds.

With servo motors, you don't have to worry about mechanical wear and friction, which helps increase their lifespan, thus resulting in lower maintenance costs over time.

It has been estimated that a single servo motor can save you up to 35% on your energy costs every year! This means that even if it is initially more expensive than conventional motors, in the long run, it will end up paying for itself by saving you money on your energy consumption.

These servo motors are highly flexible, reliable, and easy to use because of their modular design. They come with all kinds of safety features that guarantee safety and error-free functioning. Their compact design makes them even easier to integrate into any system without much hassle. They can work even under harsh conditions without causing any damage or failing functionality.

Let’s understand what is PLC system, and go down memory lane with Messung to trace the evolution of programmable logic controller technology in India.

 ABOUT PROGRAMMABLE LOGIC CONTROLLER

PLC stands for Programmable Logic Controller. The programmable controller is a specialised industrial computer that has been adapted for the control of manufacturing processes, such as assembly lines, machines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis.

The PLC control unit continuously monitors and automatically controls the different processesand components in an industrial system, gets them to function together as a well-coordinated unit, and makes decisions based on a custom programme.

Besides industrial process and machine automation, you will also find the PLC in electrical engineering where it powers modern power distribution and energy management solutions. 

HOW PLCs WORK

PLCs come in different shapes and sizes but all of them consist of four core sections:

·        The central processing unit

·        The power supply

·        The input/output (I/O) section

·        The program section

PLC system layout

Basic function of PLC is to capture data from the plant floor by monitoring inputs from connected devices and machines. The input data is then processed by the CPU which applies logic to the data. The CPU executes the user-created program logic and outputs data or commands to the devices and machines it is connected to.

PLC programming can be done in several ways, from ladder logic, which is based on electromechanical relays, to specially adapted programming languages of BASIC and C, to name a few. Most PLC control systems today use one of the following 5 industrial automation programming languages: Ladder Diagram, Structured Text, Function Block Diagram, Instruction List, or Sequential Function Charts.

PLC’s act as the physical interfaces between devices on the manufacturing floor and a SCADA or HMI system. (SCADA full form: Supervisory control and data acquisition)SCADA and HMI systems enable users to view data from the manufacturing floor and provide an interface for users to provide control input.

Now that we have an introduction to PLC and how PLC works, let’s go back in time to the period when Messung pioneered India’s first indigenous PLC.

 1981-1990 THE ADVENT & EVOLUTION OF THE PLC

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
