Industry 4.0 and the Internet of Things are a hot topic of discussion in mechanical engineering, and rightly so. This could easily give the impression that sooner or later it will be possible to replicate any technical requirement in software and perform it electronically. As long as real machines and systems produce real products, however,
Displacer instead of throttle control Modern hydraulic system solutions require often significantly less hardware components because tasks which have been carried out by the valve technology in the past, are now done by the software. The classic throttle control with valves is replaced increasingly with an intelligent displacer control with variable flow via internal gear
How can millions of machines be connected with the Internet of Things to make processes transparent and to enable monitoring and evaluation? Without intervening in the automation logic? Very easily. With only a few sensors and the IoT Gateway, which Bosch Rexroth presented at SPS IPC Drives 2016. Continuously improving manufacturing processes, decreasing production costs
Chances and challenges Motion Controls Motion controls for hydraulic actuators close the control loop in a decentralized way and release the superior control. Functions which were previously purely hydromechanical or hydraulic, are now moved into the software: Predefi ned functions take over the control of position, velocity, distance/force, diff erent synchronous cylinders or path-dependent braking.
Chances and challenges Industry 4.0 is currently the most frequently discussed topic in system and mechanical engineering and for industrial end users. The horizontal and vertical interconnection requires intelligence which is distributed on several levels – like the one widely used in electric drives – and standardized and open interfaces (as far as possible) for
