PROFINET IO Specification

In 2002, the PI has started the specification of the PROFINET realtime protocol. Both parts, ‘Application Layer Service Definition’ and ‘Application Layer Protocol Specification’ are the basis. Within the working group TC2/WG11 ‘PROFINET IO’ this specification was revised and adapted. Work on these IEC-conform documents was supported by ifak. Besides corrections new technical features e.g. DFP, MRPD or system redundancy were integrated. In November 2010 after the review and the annotation process the reworked documents ‘Application Layer protocol for decentralized periphery and distributed automation, Technical Specification for PROFINET, Version 2.3 – Date: October 2010, Order No.: 2.722’ and ‘Application Layer services for decentralized periphery and distributed automation, Technical Specification for PROFINET, Version 2.3 – Date: October 2010, Order No.: 2.712’ were published.
