Mitsubishi Electric presents its smallest and most powerful compact so far SPS. Melsec FX5UC series has an extremely compact size. It helps mechanical engineering companies to place extended functionality in a minimal space. In addition, the Programmable logic controller Web access and network connections for the latest Smart Factory applications.

Mitsubishi Electric as the inventor of the compact PLC

With the PLC family FX, Mitsubishi Electric launched the world's first compact programmable logic controller as part of the Melsec F series over 35 years ago. Over the years, the FX portfolio of the pioneer of compact PLCs has expanded and today offers the latest solutions for countless applications and requirements in automation. The record number of around 19 million Melsec FX controls installed speaks for itself.

Mitsubishi Electric has now repositioned the Melsec FX5UC series (C = compact) as part of the highly functional Melsec iQ-F series. It was developed for the increasingly demanding communication and data processing tasks for automation in smart manufacturing. The ultra-compact programmable logic controller therefore has the same CPU performance as the premium model FX5U from the manufacturer. Only that it is as small as the Micro PLC FX3S.

The ultra-compact PLC has a large data memory and a memory for programming up to 128.000 steps. Thanks to the execution speed of 34 ns, the control allows an extremely fast machine reaction and increased productivity. In addition, the FX5UC PLC can take over functions such as motion control and positioning for up to eight synchronized axes. Dedicated controls and the associated maintenance and hardware costs are eliminated. This also applies to the programming time and space requirements of the devices.

Multi-tasking capable - the ultra-compact PLC is female

Additional integrated functions protect against data theft or manipulation of machines and systems. An example of this is the authentication of security keys, while users can securely access the system status on the Internet and interact with integrated functions such as data logging.

The smallest CPU module has 16 digital inputs and 16 relays or transistor outputs. It is only a quarter the size of a conventional compact PLC. Valuable machines, systems or production areas can thus be released and space-saving control cabinets can be used.

Scalable, flexible and open PLC

When developing the new Melsec FX5UC, the designers implemented a scalable and flexible solution for the programmable logic controller. This was designed for cost-sensitive, smaller applications and larger, networked multi-PLC systems. The network capability helps manufacturers to develop integrated automation, especially when using other Mitsubishi Electric products. The complete production system with a simple system architecture and transparent data management can be controlled in this way. In addition, the open interfaces of the programmable logic controllers and their interchangeability ensure a variety of network options.

Attention was paid to many small details when looking for a flexible and assembly-friendly PLC. Tension spring terminals accelerate the wiring and ensure reliable and vibration-proof connections. Since the modules can be unlocked and moved with their wiring, maintenance and system changes can also be carried out more quickly and easily.

More news from Mitsubishi Electric

  • Cover story With a high degree of automation, Rodinger Kunststoff-Technik GmbH (RKT) ensures the required quality and efficiency in the production of various plastic parts for the automotive industry, electronics industry, communication technology and medical technology. The automation technology for the plastic injection molding machine comes from Mitsubishi Electric, including numerous 6-axis robots RV-2FR and the human-machine interface GOT2000.
  • With artificial intelligence (AI) you are also smart beforehand. Mitsubishi Electric is now using its own AI for predictive maintenance. By analyzing operating parameters recorded in real time, maintenance requirements are determined before they occur. This means that necessary measures can be planned in advance and reduced to a minimum. The automaker's AI technology is called maize. It can be easily implemented on the Melfa robot using the Melfa Smartplus add-on card.
  • User report There are still mechanical engineering companies that manufacture their required components exclusively in Germany and are also profitable. Durwen Maschinenbau GmbH manages this because it has implemented a high degree of automation in its production. In the manufacture of its add-on parts for forklifts, for example, the control of the CNC milling machines communicates directly with the handling robot from Mitsubishi Electric and does not require a master. Durwen Maschinenbau GmbH develops, produces and sells attachments for forklifts and is successful worldwide in this segment. These attachments can hold up to four Euro pallets side by side and two in a row. Can during operation...
