functional Parameter grouping entity

Note 1 to entry: It could map to a function block (see IEC 62769) or to the resource parameters of the Device itself.

mode of operation (target mode, permitted modes, actual mode, and normal mode) for a Block

Note 1 to entry: Further details about Block modes are defined by standard organisations.

fixed set of mapping rules to allow unambiguous interoperability between Devices or Applications, respectively

Note 1 to entry: Examples of such profiles are the “Wireless communication network and communication profiles for WirelessHART” in IEC 62591 and the Protocol Mappings for OPC UA in OPC 10000-6.

logical representation of the interface between a Device and a Network

independent physical entity capable of performing one or more specified functions in a particular context and delimited by its interfaces
