IO-Link Safety: Safety with Data<\/strong><\/p>\r\n

The last 20 meters in automation have long been a bottleneck: Sensors and actuators had to be wired individually \u2013 the more safety signals and diagnostic data needed to be transmitted, the more complex the wiring became. EUCHNER solves this problem with IO-Link Safety, and instead of many wires, only a single cable is needed to transmit everything. And it goes even further: more functions, more data, more than just a safety signal.<\/strong><\/p>\r\n

IO-Link Safety offers a manufacturer-independent interface for safe communication for sensors and actuators in automation technology.<\/p>\r\n

With IO-Link Safety, EUCHNER significantly simplifies communication over the last 20 meters. Instead of transmitting information via many individual wires, only a single cable is now used as a plug-and-play solution. The result: no more individual wiring. This is particularly practical for safety locking devices on machines, where many individual wires converge. Furthermore, traditional concepts provided little more than a digital signal \u2013 safe or unsafe, yes or no, safety door open or closed.<\/p>\r\n


One cable, more to it<\/strong><\/p>\r\n

The answer is IO-Link Safety. An extension of the proven IO-Link protocol that transmits safety and additional data together via a single point-to-point connection to an IO-Link Safety Master \u2013 up to SIL3 \/ PL e, standardized according to IEC 61131-2.<\/p>\r\n

The decisive advance lies not in simplified wiring alone, but in a fundamental leap in functionality: Instead of merely signaling safe\/unsafe, the devices provide context-related information. Which actuator triggered the signal? Why was a door opened? Is the door mechanism working properly? \u201cWith IO-Link Safety, we transmit safety information including context. This opens up functions that were previously not technically possible,\u201d explains Xabier Antolin, Head of Product Management at EUCHNER.<\/p>\r\n

This semantic level creates the basis for new machine concepts \u2013 and as a welcome bonus: comprehensive diagnostic data in real time.<\/p>\r\n


Good reasons for IO-Link Safety<\/strong><\/p>\r\n

IO-Link Safety uses the same connection technology as standard IO-Link. The user simply needs an IO-Link Safety-compatible master. It provides a single standard for all devices, from simple sensors to complex safety locking devices. New features such as the safe transmission of actuator IDs, key data, or mechanical status provide information that was never available via traditional wiring. At the same time, planning and installation efforts are significantly reduced: a single cable replaces many individual wires. Device parameters can be quickly transmitted via IO-Link Safety, enabling fast device replacement without long downtimes. In addition, comprehensive status data and diagnostic logs are available in real time. The user not only sees that errors have been triggered, but also why \u2013 this reduces downtime and facilitates targeted maintenance.<\/p>\r\n


Safe communication via standard cables \u2013 without additional effort<\/strong><\/p>\r\n

The connection between the IO-Link Safety Master and the devices upgrades traditional individual wiring to a fully-fledged safe communication interface and does not require complex network technology.<\/p>\r\n

Technically, IO-Link Safety is based on the so-called black-channel approach: safety data is transmitted via a physically unsafe channel but is reliably protected. For the user, this means full safety without having to configure details themselves.<\/p>\r\n

Compared to traditional safety bus systems, IO-Link Safety uses compact data structures and cyclic point-to-point connections. Response times remain low, and the system architecture is straightforward.<\/p>\r\n
