Software-based PLCs pose challenge to traditional hardware infrastructure

by Leave a Comment

By Sharmila Annaswamy, IoT Analytics

Software is increasingly replacing hardware in industrial environments. Software-based programmable logic controllers (Soft PLCs) today are reliable, powerful and flexible.

Soft PLC adoption is expected to double between 2019 and 2025, posing an “innovator’s dilemma” for incumbent industrial automation vendors.

Actions taken by incumbents will prevent significant disruption in the near-term, but the long-term threat of soft PLCs will remain. [Read more…] about Software-based PLCs pose challenge to traditional hardware infrastructure

Top 20 programmable logic controller manufacturers

by Leave a Comment

Sometimes described as “the workhorse of industrial automation”, a programmable logic controller, or PLC, is a computing device that is specially designed for use in an industrial operation.

A PLC can take many shapes and sizes, but in most instances it does not look like a conventional desktop computer like the ones you find in offices or in homes – a PLC has no display screen, no hard drive, and no keyboard.

PLCs started out in the automotive manufacturing trade, although they can now be found in almost all sectors, where they tend to replace relays.

Relays are devices that essentially turn machines on and off, and are said to be time-consuming and complex to use compared to PLCs. Relays also require more operational downtime when they need to be reconfigured. PLCs are estimated by one research company to reduce downtime from 20 percent to about 4 percent.

How to simplify the control architecture of cartesian coordinate robots

by Leave a Comment

By Barry Weller, product manager at Mitsubishi Electric

In order to remain competitive, it is generally accepted that industries should adopt lean manufacturing strategies to improve process efficiency.

A key action can be to reduce part count, that is to say the number of components in an assembly or system. This is particularly challenging when it comes to highly accurate cartesian coordinate (linear) motion applications.

In these cases, machine builders would often need to use both PLCs and computer numerical controllers (CNCs) in order to fully manage movement within the machine – until now. [Read more…] about How to simplify the control architecture of cartesian coordinate robots

SICK’s Industry 4.0 training gets you started with IO-Link on the PLC

by Leave a Comment

SICK is holding a series of hands-on training days to help machine builders and end-users progress on their Industry 4.0 journey by unlocking valuable data from IO-Link sensors via a PLC.

During the one-day course, delegates will learn, step-by-step, how to set up an IO-Link Master to enable sensors to communicate data with a PLC.

By the end of the course, “Getting Started with IO-Link on Your PLC”, delegates will be able to control and monitor sensors from the PLC and collect data which can be used to increase plant efficiency and productivity.

Mitsubishi launches ‘smallest, most compact’ programmable logic controller

by Leave a Comment

Mitsubishi Electric has released the company’s smallest and most powerful compact programmable logic controller to date – the FX5UC series Premium Micro PLC.

The company says the new PLC’s diminutive size is set to help machine builders and manufacturers pack “ever more functionality into a smaller space”, while also providing the web access and network connectivity demanded by the latest smart factory applications.

Mitsubishi Electric launched its first range of micro controllers, the FX family of PLCs, over 35 years ago as part of the MELSEC-F series. [Read more…] about Mitsubishi launches ‘smallest, most compact’ programmable logic controller

Bosch Rexroth provides insight into measurement and testing processes

To ensure consistency, repeatability, quality and compliance with regulations, many companies employ rigorous testing and measurement processes.

Kraus automation technology (KAT), specialises in providing tailored testing systems for life-span, fatigue and material tests.

To offer testing systems which meet the needs of their diverse customer base, KAT use National Instruments’ LabView software to create custom user interfaces for engineers. [Read more…] about Industrial measurement and testing: Faster commissioning results in quicker time to market

Parker Hannifin introduces new servo drive range

by

Parker Hannifin, a leader in motion and control technologies, has introduced its PSD series of servo drives designed for use in central control applications.

All components utilise an Ethernet-based fieldbus system for communications with the controller via popular fieldbuses, currently in use in industry, such as EtherCAT, Ethernet IP and PROFINET.

Due to its flexibility, the new system can be used in a wide range of applications including highly dynamic packing and production machinery.
