The IO-Link standard for point-to-point communication between sensors, actuators, and controllers has been expanded to include TÜV-certified, safety-related communication on the same physical infrastructure. IO-Link Safety offers standardized wiring, reduced complexity, and consistent diagnostic capabilities for safety-relevant signals up to PLe/SIL3. Safety functions such as emergency stops, door interlocks, and light curtains can be implemented directly via IO-Link and safely connected to the control system without complex wiring.
Security Deployment Guideline
The IO-Link Community has also published a new Security Deployment Guideline intended to help users evaluate and implement security measures for the use of IO-Link. The main objective of the IO-Link Secure Deployment Guideline is to provide end users with the knowledge and tools necessary to effectively assess and implement security measures for the use of IO-Link technology. The document provides detailed instructions and best practices for the use of secure IO-Link systems.
In addition to the directive for the use of IO-Link, a further guideline for the secure design and secure development of IO-Link products is currently being developed. The IO-Link Secure Design and Development Guideline will provide a comprehensive guide to understanding and integrating security measures into IO-Link product development. The editorial work on the development guidelines is nearing completion.
The Secure Deployment Guideline is available for free in the download area on the IO-Link website.
