IEC 61784 discusses industrial communication networks. IEC 61784-1 is the first part of the IEC 61784 multi-series and discusses Fieldbus profiles used in industrial communication networks. IEC 61784-1 defines a set of protocol-specific communication profiles based primarily on the IEC 61158 series, to be used in the design of devices involved in communications in factory manufacturing and process control.
Each profile selects specifications for the communications protocol stack at a device. IEC 61784-1 contains a minimal set of required services at the application layer and the specification of options in intermediate layers defined through references. If no application layer is included, then a minimal set of required services at the Data-link layer is specified. The appropriate references to the protocol-specific types are given in each communication profile family or associated profiles.
IEC 61784-1 on Fieldbus profiles used in industrial communication networks is useful for:
IEC 61784-1 provides a set of Communication Profiles (CP) in the sense of ISO/IEC TR 10000-1. These answer the need of identifying the protocol families co-existing within the IEC 61158 series, as a result of the international harmonization of Fieldbus technologies available on the market.
More specifically, these profiles help to correctly state the compliance to the IEC 61158 series and to avoid the spreading of divergent implementations, which would limit its use, clearness, and understanding.
IEC 61784-1 contains several Communication Profile Families (CPF) that benefit users which specify one or more communication profiles. IEC 61784-1 helps you in real-time distributed control for industrial computer networks.
The profiles defined in IEC 61784-1 are helpful to users’ steps to achieve that task.
