[中文适用范围]： 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 part of IEC 62453 provides information for integrating the PROFINET technology into the FDT interface (IEC 62453-2). This part of the IEC 62453 specifies communication and other services. This specification neither contains the FDT specification nor modifies it. [外文原描述]： IEC 62453-303-2:2009 provides information for integrating the PROFINET® technology into the FDT interface (IEC 62453-2). It specifies communication and other services.
