Top 10 PLC Manufacturers

            The industrial automation market is one that is set to be in constant growth for many years. There are plenty of reason for this, the most basic ones go around the fact that the industry is always in need of process optimization and revenue. Right now, they are obtaining this by looking for ways to reduce shutdown time as little as possible, and this come at hand with optimum error handling and a more skillful workforce.

            Of course, having a skillful workforce is not easy to control, that is why another trend of the market is making PLCs based systems easier to use. In general, the modernization of the market is what they are aiming for; it is not a secret that technology in the consumer world advances faster than in the industrial sector. Although, this doesn’t mean the industrial sector is not looking to make more advanced devices, is just that they won’t do it at the expenses of reliability and long-term installations.

            At the end of the day, as long as the industry have problems to be solved, the PLC market is going to keep growing. And this growth is actually certain due to the fierce competition between the bigger names of the market. Below, we will list the top PLC manufacturers that are leading the PLC market at the moment.

Of course, the industrial automation sector is part of their interest, and for the last few years have been one of the principal protagonists in this.

Their PLC selection is not as wide as some of their competition, but they do offer great quality and range of features in the solutions they focus on. The SIMATIC S7-1500 offers a future proof solution thanks to its modular nature and high performance. Then the SIMATIC S7-1200 offers a better approach for lower to medium range applications looking for full featured devices. Lastly, they have their line of distributed controller for distributed designs and small spaces.

This edge came in the form of the famous lines of PAC and compact PLCs, PACSystems and VersaMax respectively. These lines offer a huge range of solutions for different applications, VersaMax in particular is a great option for compact solutions, robust, and modular solutions, a favorite when it comes to learning and mobile operations.

They are a company that sells electronic systems, components and equipment, this includes the industrial automation sector. But they are mostly known by their medical electronic equipment.

Their line of PLCs has an interesting focus on compact implementations, offering high performance devices for small spaces in their CP line of products. That doesn’t mean that they can’t offer solutions for bigger installation, they offer their standard CJ2M line of PLCs, and their even bigger and more capable CS1 CPU.

Panasonic offers quality products in their lines of PLCs, this line ranges from premium to compact solutions. These PLCs have all the features needed by most plants and are programmable with just piece of software since 1995. This is a huge reason for them to be in this list, since longevity and ease to upgrade is really important in the business.

10. Robert Bosch GmbH      

Founded in 1886, this German giant is one of the biggest companies spread in different industry sectors, and has different subsidiaries that specialize in others. Before 2001 Bosch did have their Automation Technology Business, but it was merged with Mannesmann Rexroth AG, resulting in Bosch Rexroth AG. This is the subsidiary in charge of the industrial automation sector for Robert Bosch GmbH.

Bosch offers top of the line options for industrial automation installations. They have their CML line, which is a classic PLC line with as many features as possible and modularity in mind. On the other hand, the XM series offer a more compact, but robust solution, with the possibility of adding modules to create a complete automated system. It is worth noting their VPB series, which offers a PLC system connected to a PC control solution, having the best of both worlds at hand.

Today is really hard to differentiate a PLC from a PAC, some companies even have them categorized in the same way. This is because of how well featured PLCs are nowadays, Bosch even offers a PC – PLC solution. This shows how important is for these companies to offer a wide range of products, to be able to suffice not only the larger plants and projects, but also the mid-range and lower-end necessities of the industries.

Have in mind that this list has no particular order at the moment of picking a PLC supplier, they all have their pros and cons. Their positions were based on how well placed they are in the market. This a very competitive business and there is a specific demand depending on the needed solution, sometimes you don’t need a brand for how big they are, but for the solutions they offer.
