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

3.1.1 block

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.

3.1.2 blockMode

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.

3.1.3 Communication Profile

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.

3.1.4 Connection Point

logical representation of the interface between a Device and a Network

3.1.5 device

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: Devices provide sensing, actuating, communication, and/or control functionality. Examples include transmitters, valve controllers, drives, motor controllers, PLCs, and communication gateways.

Note 3 to entry:  A Device can be a system (topology) of other Devices, components, or parts.

3.1.6 Device Integration Host

Server that manages integration of multiple Devices in an automation system

3.1.7 Device Topology

arrangement of Networks and Devices that constitute a communication topology

3.1.8 fieldbus

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.

3.1.9 Parameter

variable of the Device that 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.

3.1.10 Network

means used to communicate with one specific protocol

3.1.11 Direct-Loading

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

3.1.12 Cached-Loading

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

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

3.1.13 File System based Loading

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

3.1.14 Software Package

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

3.1.15 Software Update Client

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

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

3.1.16 Current Version

version information of the software that is currently installed

3.1.17 Pending Version

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

3.1.18 Fallback Version

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

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