Communication Profile 3/1 and Communication Profile 3/2 (commonly known as PROFIBUS?1) 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?C2 [103.00.02]). This part of the ISA-62453 specifies communication and other services. This specification neither contains the FDT specification nor modifies it.
