For the purposes of this document, the terms and definitions given in OPC 10000-1, OPC 10000-3, and OPC 10000-8as well as the following apply.

functional Parametergrouping entity

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

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

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

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

Note 1to 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 Deviceand a Network

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

Note 1 to entry: See IEC 61499-1.

Note 2 to entry: Devicesprovide sensing, actuating, communication, and/or control functionality. Examples include transmitters, valve controllers, drives, motor controllers, PLCs, and communication gateways.

Note 3 to entry:  A Devicecan be a system (topology) of otherDevices, components, or parts.

Serverthat manages integration of multiple Devicesin an automation system

arrangement of Networksand Devicesthat constitute a communication topology

communication system based on serial data transfer and used in industrial automation or process control applications

Note 1 to entry: See IEC 61784.

Note 2 to entry: Designates the communication bus used by a Device.

variable of the Devicethat can be used for configuration, monitoring or control purposes

Note 1 to entry: In the information model it is synonymous to an OPC UA DataVariable.

means used to communicate with one specific protocol

an update method where the original software is overwritten during the transfer

an update method where the new software is stored in a separate area

Note 1to entry: Installation is performed later as an extra step.

an update method based on an accessible directory structure and a separate install method

a single file that contains the data for the software update in a device specific format

an update client that can be used for devices of several vendors

Note 1to entry: There can be different Software Update Clients for different domains (e.g. process industry or manufacturing).

version information of the software that is currently installed

version information for a Software Packagethat was transferred before and is ready to be installed

version information about an alternatively installable software that is located on the Server

Note 1to entry: Examples: factory default version or the version before the latest update
