Communication Profile 3/1 and Communication Profile 3/2 (commonly known as PROFIBUS(TM)2) defines communication profiles based on IEC 61158-2 Type 3, IEC 61158-3-3, IEC 61158-4-3, IEC 61158-5-3, and IEC 61158-6-3. The basic profiles CP 3/1 (PROFIBUS DP) and CP 3/2 (PROFIBUS PA) are defined in IEC 61784-1. This part of IEC 62435 provides information for integrating the PROFIBUS protocol into the FDT interface specification (IEC 62453-2). This part of the IEC 62453 specifies communication and other services. This specification neither contains the FDT specification nor modifies it.
