ervos and HMIs play a key role in many industrial automation applications. While servos are responsible for moving
machine parts with high precision, HMIs provide a platform that maximises data availability and enables accurate process visualisation. Since these components greatly contribute to defining the effectiveness of an automated system, companies will need to identify the features and capabilities that are best suited to their application.
Servo Selection
High-performance servos enable companies to create ambitious high-speed automated systems with exceptional position accuracy. This means specifying robust components that can also offer future-oriented diagnostics and predictive maintenance functions. Selecting a drive that supports communications with both the IT and OT levels of a business can provide an opportunity to gain more comprehensive actionable insights. Size is another aspect to consider, and looking
at the dimensions of servo motors and amplifiers is a good starting point. Other features that can greatly help to reduce the space required by a device include reduced cabling and battery-less solutions. In addition, the ability of servos to handle multiple axes, incorporate safety functions without the need for specific modules, as well as the possibility to use one single amplifier to control multiple motors, are key to reduce the bill of materials. An example of a solution that can
address all these needs is Mitsubishi Electric’s MELSERVO MR-J5 range of CC-Link IE TSN compliant servos. This new series of servo motors and amplifiers was presented for the first
4
time to the UK market at Drives & Controls 2022. The servo systems are designed to offer
next-level performance in terms of cycle times, accuracy and control of multiple axes – up to as many as 768. To support compactness and flexibility, the MR-J5 range does not require a battery and needs minimal cabling, even when connected to multiple motors. It also incorporates safety communications, in addition to TSN functions for next-level data availability and convergence. Finally, it provides AI-powered advanced diagnostic functions and condition monitoring capabilities to prevent unexpected downtime and optimise maintenance.

It is often believed that HMIs are all identical and there is limited scope for evolution in the technology that underpins these platforms. However, these statements could not be further from the truth. There are certainly a number of core functionalities that anyone would expect these interfaces to have, such as real-time data logging and handling, the ability
able to support the main principles of Industry 4.0, particularly interoperability, decentralisation and service-orientation. In fact the ability to connect this type of system to any device without the need for dedicated networks or monitors is becoming increasingly important. To turn any screen into an HMI can be
highly beneficial, as companies can maximise flexibility as well as support for remote monitoring. By offering web-based access, an HMI provides operators with a cost-effective solution for checking the shop floor and controlling devices from anywhere through a web browser. Even more, it can be used by companies to display multiple interfaces on a single screen and gain a comprehensive overview of all activities as well as their status. Finally, an advanced platform should
streamline and simplify the creation of new HMI projects and recipes. This is key to shortening implementation times while also helping less experienced users set up systems in line with an existing automation infrastructure and its needs. Mitsubishi can help with its GOT 2000 HMIs as
well as smart, web-based, remote access via GOT mobile, which supports up to five simultaneous and independent connections to worksite interfaces. Systems like this usually require users to log in and validate their credentials every time. However, to streamline this process, Mitsubishi Electric has developed GOT mobile ANDON to support pre-authentication, allowing authenticated users to add an approved device. This can be useful, for example, when a large screen is used to supervise or look at operations to showcase factories in visitor centres. Another tool that makes HMI operation even more practical is Soft GOT. This software runs on computers, such as industrial PCs, and is used to monitor and operate industrial devices that are connected to the computer via a network. It maximises flexibility as companies can repurpose their PCs as HMIs. Thanks to the GOT Link function, it is also possible to run up to four different interfaces on a single screen. Furthermore, Mitsubishi Electric’s data

utilisation capabilities across the entire GOT range empower users to upload standard or existing projects to the HMI without requiring any additional programming.
