Communication Profile 3/1 and Communication Profile 3/2 (commonly known as PROFIBUS™) 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 ISA-62453 provides information for integrating the PROFIBUS protocol into the FDT interface specification (ISA-62453-2 [103.00.02]).This part of the ISA-62453 specifies communication and other services. This specification neither contains the FDT specification nor modifies it.
