Specification boosts IO-Link deployment

A The Profibus Group product story
Edited by the Engineeringtalk editorial team May 13, 2008

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.

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.
