“IoT demands shared

“IoT demands shared protocols and interfaces across all levels and technologies”, states Dieter Michalkowski (center) of Aventics Predictive maintenance ensures max. utilisation of machine capacities MEASUREMENT AND CONTROL The much talked about ‘Internet of Things’ (IoT) has now reached the factory floor and is influencing the daily production related activities in a manufacturing set up. For the pneumatics company Aventics, predictive maintenance based on the concepts of ‘IoT’ has now become an integral part even in its customer meetings. The pneumatics experts at Aventics observed that, while in the past concerns were focused mainly on an extended product service life, today predictive maintenance has become equally important. “We recognized the need early on and already considered the topic when developing our most advanced generation of valves,” explains Dieter Michalkowski, IoT expert at Aventics. Machines are becoming key strategic factors of success, not only for large corporations with production systems that are often worth several hundred million euros, but also for medium-sized businesses. Maximum utilization of machine capacities, no stoppages, short maintenance breaks, short cycle times, and just-in-time production are essential topics. To ensure its smooth operation, forward-thinking servicing, or “predictive maintenance”, is becoming more and more important. Predictive maintenance – a professional tool, not a crystal ball Predictive maintenance can be costly affair but it is also available even for limited budgets. Aventics utilizes already existing sensors to diagnose the status of the systems. For example, wear components such as shock absorbers are monitored using the installed cylinder switches. “This enables us to establish the condition of shock absorbers, as well as actuators or guides, by monitoring the time response for the process steps. This has nothing to do with fortune telling and crystal balls, it is precision engineering based on extensive pneumatic expertise,” points out Michalkowski. The rapidly increasing digitization of machines and systems creates the basis for this approach. “At the same time, we keep an eye on investment security – existing systems and components must be compatible with both older and future versions. To us, this is part of the development process. In machine and system construction we follow a different approach than, for example, the IT sector – systems ordered today must remain productive tomorrow and beyond,” he emphasizes. At Aventics, the AV series valve system with the innovative AES series electronics constitutes the basis for IoT applications. The product range includes valves with a long service life About Aventics Aventics is one of the world’s leading manufacturers of pneumatic components, systems, and special applications. With over 150 years of expertise in pneumatics, Aventics employs around 2,100 associates worldwide. In addition to production sites in Germany, France, Hungary, USA and China, Aventics is represented in more than 40 countries. The company provides tailored solutions for the sectors of industrial automation, commercial vehicles, food and beverage, energy and marine technology. MDA Technologies 3/2016

About ifm electronic gmbh Founded in 1969, ifm electronic gmbh has its headquarters in Essen and develops, manufactures and distributes sensors, controllers and systems for industrial automation worldwide. Today the second-generation family-run company with about 5,500 employees in more than 70 countries is one of the worldwide industry leaders and generated total sales of € 720 million in the year 2015. 01 Developed by ifm electronics, the Smart Observer visualizes the recorded measured values 02 ifm offers a wide range of IO link sensors for predictive maintenance that tops 150 million cycles, as well as electronic components that enable processing of the collected data. Process signals are recorded locally via I/O modules and transferred to the control. The combination of AV and AES series is the hub that links actuator and sensor signals. These can then be evaluated to recommend measures for predictive maintenance — no additional components are required. Michalkowski is certain that “IoT demands shared protocols and interfaces across all levels and technologies. Data is exchanged via real-time Ethernet. This requires cross-manufacturer approaches.” SEAL TECHNOLOGY PREMIUM QUALITY SINCE 1867 COG MAKES ITS MARK: The world‘s largest O-ring warehouse. Cross-manufacturer cooperation Aventics has expanded its cooperation with ifm electronic GmbH for IoT applications. The pneumatics specialists want to pool their knowledge with that of the manufacturer and supplier of sensors and controls. The aim of the joint activities is to fully and reliably monitor and analyze all data online, independent of the machine control, to increase customer benefits. Thanks to direct communication of sensor and pneumatic systems, machine status data, such as the current energy consumption, can be monitored more effectively than before and optimization measures can be introduced early on. With this approach, both companies support the implementation of the European Energy Efficiency Directive (EED). According to the new directive, all enterprises with 250 employees and more must complete an energy audit by the end of 2016 and furnish proof of a certified energy management system to ISO 50001 or environmental management system to EMAS.
