NEW HMI SOFTWARE FEATURES IMPROVE OPERATOR EFFICIENCY FactoryTalk View software updates offer better information access, mobile support and software integration FactoryTalk View software version 10.0. New features include greater access to information, new mobile device support and better cross-software integration to improve productivity. 10 Rockwell Automation has updated its HMI software to equip industrial workers with better information to run and maintain their systems. New features in the FactoryTalk View software version 10.0 include greater access to information, new mobile device support and better cross-software integration to improve productivity. Operators can now use the TrendPro tool in FactoryTalk View Site Edition (SE) software to overlay alarm information on trend data. This feature can help them connect alarm occurrences with data-point values to speed up troubleshooting. They can also use the tool to save and share ad hoc trends with other workers. “This version also adds support in the HMI for flexible alarming with the Allen-Bradley Logix line of controllers,” said Christo Buys, Business Manager – Control Systems Rockwell Automation Sub-Saharan Africa. “Previously, users had to manually create alarm conditions in both the controller and the HMI. With tagbased alarming, operators can now create the alarm configuration in Logix and the HMI will process it automatically, which saves time by reducing the need for programming.” FactoryTalk View SE v10.0 also integrates the ThinManager software login into the FactoryTalk View platform. In the past, users had to separately log in to both systems. Now, they can bypass the second security point with an automatic login pass-through for easier and faster operations. For process industries, the FactoryTalk View SE software introduces an abnormal situation management (ASM) multi-monitor framework. This feature allows operators to see different levels of data across multiple screens in accordance with standards-based ASM guidelines. It can also provide operators with more viewable information, helping them more efficiently run and maintain their systems. The updated FactoryTalk ViewPoint software, which extends the FactoryTalk View SE software to mobile devices, now supports recipe management. This update allows workers to view and download recipes on the device of their choice. And now, with ViewPoint v10.0 software, FactoryTalk Alarms and Events alarm history is also available on their mobile devices. The FactoryTalk View Machine Edition (ME) software v10.0 adds design-time and run-time enhancements to improve user efficiency and productivity. The HMI software now better supports restoring and upgrading legacy projects and improves usability when editing displays. “Prior to this release, operator actions could be logged to an audit trail, but there was no guarantee that the system would capture them,” said Buys. “Now with onboard audit trails, this information is captured locally on the terminal, and audit data is securely stored there until it can be backed up. For highly regulated industries, like pharma production, this supports requirements such as US 21CFR Part 11 or EU Annex 11.” About Rockwell Automation Rockwell Automation Inc. (NYSE: ROK), the world’s largest company dedicated to industrial automation and information, makes its customers more productive and the world more sustainable. Headquartered in Milwaukee, Wis., Rockwell Automation employs approximately 22,000 people serving customers in more than 80 countries.

LINEAR ENCODERS FOR FUTURE-PROOF POSITION MEASUREMENT IN HYDRAULIC CYLINDERS There is an increase in the demand for linear sensors for mobile automation in general and, even more so, for hydraulically driven machines. But the quantitative aspect is just one side of the story. This, according to Alexander Hurt, Head of Linear Encoders Business Unit, SICK AG, Germany. The MAX linear encoder, which has been developed specially for mobile automation applications, can take complete, integrated, and non-contact absolute position measurements in hydraulic cylinders. It is primarily used in the extreme environmental and operating conditions that are typical for mobile machines. When digging, the option to control the depth of excavator shovels using position measurement avoids damage being caused to cables, pipes, and foundations. More and more vehicle manufacturers, integrators, and operations managers are setting their sights on top-quality innovations. Everyone wants the added value that came to be standard within industrial automation long ago: the encoder needs to gather status and process information. In future, precise, high-performance position measurement is set to come with the added option of performing detailed analyses on the basis of sensor information. This will make it possible, for example, to provide support for assistance systems, avoid sudden machines failures, optimise maintenance routines, and improve machine availability on the whole. Within the field of hydraulic measurement technology for mobile automation, the linear encoders in SICK’s MAX product family are currently the only devices of their kind to offer this added value. They operate in line with the robust operating principle of magnetostriction, provide extensive diagnostic functions (the first sensors of their kind), and offer added value for mobile machines that will continue to be relevant as we head into the future. Innovation with magnetostriction One key feature of the new SICK linear encoders is their full mechanical compatibility with existing cylinder constructions that are already prepared for integration into a path measurement system. Integration into Alexander Hirt, Business Unit Head: Linear Encoders. Hirt has been in charge of the linear encoders business unit since 2016 and he, and his team, established the magnetostriction technology in the SICK portfolio. hydraulic cylinders is therefore guaranteed to be a quick and easy process. Inside these linear encoders, there are various technologies and innovations when compared to the market standard. On the basis of more than 25 years of experience in linear path measurement technology for mobile machines, SICK STEGMANN began by studying the market requirements and then went on to develop a radical new sensor concept. The main features include the use of magnetostriction, the optimisation of the power density by minimising measurement dead zones, and the integration of diagnostic and prognostic functionalities that can be used to avoid machine downtimes and improve operational plans and maintenance routines for entire fleets. Magnetostriction technology offers a number of benefits when linear encoders are used in hydraulic machines. Position measurement is absolute – the precise piston position is detected as soon as on-board voltage is supplied when the machine is started up. There is no need for a reference run, as is the case with incremental sensors. During operation, magnetostriction is exceptionally reliable, wear-free, and even robust, proving particularly resistant to mechanical stress and extreme electrical influences, such as those caused by radiated or coupled faults in the on-board power supply of a vehicle. The high level of operational safety of the MAX linear encoder as a device within vehicles that requires approval is certified by the E1 approval mark issued by the German Federal Motor Transport Authority. Excavators can be fully automated and operated with extreme precision when removing highway embankments. The MAX linear encoders make it possible to automate and monitor work processes performed by mobile machines. 11
