Field device tool (FDT) interface specification. Communication profile integration. IEC 61784 CPF 15 | Status: Current

1 Scope Communication Profile Family 15 (commonly known as Modbus1) defines communication profiles based on IEC 61158‑5‑15 and IEC 61158‑6‑15. The basic profile CP 15/1 (Modbus TCP) is defined in IEC 61784‑1. An additional communication profile (Modbus Serial Line) is defined in [2]. This part of the IEC 62453 provides information for integrating Modbus TCP® and Modbus Serial Line® protocol support into FDT based systems.

NOTE This part of IEC 62453 only specifies the mapping of Modbus parameters to FDT data types. For restrictions of protocol specific parameters concerning allowed values and concerning limitations of arrays used in the definition of FDT data types, refer to IEC 61158‑5‑15 and the MODBUS Application Protocol Specification.
