Specification boosts IO-Link deployment
PI's integration specification forms the basis for the wider deployment of IO-Link in Profibus and Profinet systems.
PI (Profibus and Profinet International) has published documents on the integration of IO-Link into Profibus and Profinet Together with the existing physical layer and protocol specification, the integration specification forms the basis for the wider deployment of IO-Link in Profibus and Profinet systems

Conference to draw UK and European bus experts
The fifth annual UK Profibus and Profinet User Conference will combine the conference with practical workshops and and exhibition featuring many live demonstrations.
The requirements for the development of products with IO-Link interface were laid out with the physical layer and protocol specification.
Most sensor manufacturers and manufacturers of I/O modules have released IO-Link products.
The integration documentation provides the basis for open integration of IO-Link in Profibus and Profinet systems.
The physical layer and protocol specification of IO-Link is fully independent of Profibus and Profinet, so IO-Link can be subordinated to all fieldbuses or Ethernet-based systems.
Work to integrate IO-Link into additional fieldbus systems is already in preparation.
A suitable device description is of significant importance here.
The definition of an appropriate independent device description for IO-Link, IO Device Description (IODD), is already under review by PI.
