IEC 62453-303-2 Ed. 1.0 en:2009

IEC 62453-303-2:2009(E) provides information for integrating the PROFINET technology into the FDT interface (IEC 62453-2). It specifies communication and other services. This specification neither contains the FDT specification nor modifies it. Communication Profile 3/4, Communication Profile 3/5 and Communication Profile 3/6 (commonly known as PROFINET IO) define communication profiles based on IEC 61158-5-10 and IEC 61158-6-10. The basic profiles CP 3/4, CP 3/5, and CP 3/6 are defined in IEC 61784-2.

This publication is to be read in conjunction with IEC 62453-2:2009.
