IO-Link valve and IAC-valve as connected hydraulics

摘要

IO-Link allows end-to-end communication with sensors and actuators, irrespective of the fieldbus used. The proportional valves used in hydraulic systems now fit into bidirectional digital communication - intelligently, simply and cost-effectively. This simplifies commissioning in hardware and software and allows flexible adjustment of hydraulic valves for varying production processes. The increased requirements as regards flexible machinery and systems are now met. The expanded diagnostic information allows status-oriented and predictive maintenance concepts and significantly reduces downtimes and maintenance times. This helps to increase the availability of machines. IO-Link also integrates the hydraulic valves used into connected structures in a future-proof manner - as fully-fledged Industry 4.0 components. The advantages of distributed intelligence for hydraulic drive technology are leveraged by Bosch Rexroth through the integration of axis controller functions (IAC integrated axis controller). Our high-response valves with integrated digital axis controller actively control the axes independently of the machine control by using separate motion functionality and process the data of various sensors that can be connected directly. The compact modules are based on proven proportional and high-response valves and offer a wide variety of axis controller functions in addition to easy integration in the control concept.
