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 IEC 62453 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.
