Industry 4.0 diagnostics for pneumatics through direct digital control: IO-Link® module added to ASCO Numatics 580 Series electronics platform
Emerson has expanded the ASCO Numatics 580 Series fieldbus electronics platform with the introduction of an IO-Link® communication option. For use with the ASCO Numatics 500 Series valve islands, the new IO-Link module offers a convenient, cost effective and reliable solution for solenoid valve control through direct digital data communication with the machine controller plus the ability for event-based and I/O mapped diagnostics – important predictive maintenance requirements for Industry 4.0.
The 580 Series IO-Link is compatible with the full range of 501, 502 and 503 Series valve islands which offer from 400 to 1400 l/min flow rates in valve sizes of 11, 18 and 26 mm. Now available with base-plates that allow two pressure sizes to be combined in one convenient assembly, simplifying installation and allowing valve piloting and pneumatic systems from the same island. The modular range offers the market’s highest flow capability for its product size, keeping machine footprints compact and lowering system costs. A comprehensive range of options are available for complete application flexibility.
IO-Link is gaining increased popularity for automation systems, offering an internationally standardised I/O technology (IEC 61131-9) for communication at the sensor/actuator level in machine control. The ASCO Numatics 580 Series IO-Link module offers many advantages such as simple commissioning with unshielded 3-wire comms connection and 4- or 5-pin industry standard M12 connectors for power and communications. In addition to increased machine availability through enhanced diagnostics, further benefits include parameter setting with IO-Link’s integral device description protocol (IODD) plus simple configuration parameter update and uncomplicated component exchange. When used with the 500 Series valve islands and a compatible IO-Link master, a modular distributed I/O topology is easily achieved for up to 32 solenoid outputs per master in addition to third-party sensors, relays and other field level components.
IO-Link is independent of upper level fieldbus systems and is available for almost all major fieldbus protocols available today. This neutrality allows OEM’s to choose their preferred supplier for top-level machine controls - and automation machine upgrade or expansion costs can also be kept to a minimum by using existing PLC controls whilst increasing field level functionality. Programmers can also benefit from IO-Link’s impressive capabilities – I/O mapped diagnostics make for simplified PLC control and event based diagnostics offer cloud processing of the data via a compatible master.
The 580 Series IO-Link is ideally suited to distributed machine architectures where sensors and pneumatic systems are located close to each other and where high reliability digital data communication between field devices and the machine controller is desirable. Applications include but are not restricted to conveying and robotics, pick and place and assembly machines, and all areas of packaging machinery.
