communication channel connection between a transmitter/sender and recipient/receiver which allows the exchange of information
component manager organizer of self-management and of access to the resources of the I4.0 component, for example, I4.0 component, item, technical functionality, virtual representation Note: In many documents, component manager is referred to as resource manager, but the term component manager should be used in future.
core model reference model of basic concepts and contexts which concern a general aspect of systems
cyber physical production system (CPPS) CPS which is used in production
cyber physical system (CPS) system which links real (physical) objects and processes with information-processing (virtual) objects and processes via open, in some cases global, and constantly interconnected information networks A CPS optionally uses services available locally or remotely, has human-machine interfaces, and offers the possibility of dynamic adaptation of the system at runtime.
deployment view structural mapping of applications to resources Practical example is the distribution of the contents of an administration shell across different IT systems.
digital twin Definition 1: Virtual digital representation of physical assets.

Definition 2: Simulation model || In future, the digital twin will be a synonym for the asset administration shell if the development will continue as before. In the context of Industrie 4.0, the term asset administration shell is preferred.

ecosystem loose community of various autonomous players connected in a network with a common goal of creating products and/or services based on a (standardized) communication and system infrastructure Players can be participants of the value-added system as well as educational or research institutions, political units, standardization organisations or associations.

Within an ecosystem, players can be engaged at the same time both in cooperation and in competition. n ecosystem is characterized by a common further development (co-evolution) of the players and the ecosystem

event sudden change that can be observed An event can trigger a state transition in a state model.
flexibility characteristic of an item, to adopt it with little effort to changes which were known during planning
horizontal integration integration within a functional/organizational hierarchical level across system boundaries
horizontal interaction interaction within a functional/organizational hierarchy level across system boundaries
human-machine interaction collaboration between users and technology, such as computers, machines or CPS Implemented by human- and task-oriented technical systems at the interface between users and technology.

Includes the analysis, design and evaluation of such systems. Collaboration synonymous to interaction

I4.0 component globally uniquely identifiable participant with communication capability consisting of administration shell and asset (corresponds to CP24, CP34 or CP44) within an I4.0 system which there offers services with defined QoS (quality of service) characteristics For its services and data, the I4.0 component offers protection commensurate with the task.

An I4.0 component can represent a production system, a single machine or station, or even an assembly within a machine.

I4.0 platform implementation of a (standardized) communication and system infrastructure with the necessary management and production services and defined QoS (quality of service) characteristics as a basis for the efficient construction and integration of I4.0 systems in an application domain To ensure interoperability, an I4.0 platform must be based on a reference architecture.

An I4.0 platform must define a relation to the I4.0 system.

I4.0 system system, consisting of I4.0 components and components of a lower CP classification, which serves a specific purpose, has defined properties, and supports standardized services and states A system may be present as a component in a further I4.0 system.

An I4.0 system must define a relation to the I4.0 platform. Flexibility, transformability, etc. are features of an I4.0 system

interface defined connection point of a functional unit which can be connected to other functional units “Defined” means that the requirements and the assured properties of this connection point are described.

The connection between the interfaces of function units is also called an interface. In an information system, the defined exchange of information takes place at this point. An interface places certain requirements on the connection that is to be made. An interface demands certain features.

interoperability ability of different components, systems, technologies, or organizations to actively work together for a specific purpose Interoperation is collaboration put into practice.
lifecycle continuous number of processes which an item passes from creation to dissolution
manifest externally accessible defined set of meta-information, which provides information about the functional and non-functional properties of the I4.0 component The manifest can be regarded as similar to the manifest in computer science.
Middleware Software that provides services to software applications beyond those available from the operating system.
model coherent, sufficiently detailed abstraction of aspects within a field of application
non-functional requirement requirement that does not belong to the actual system function Examples: availability, performance, usability, compatibility, maintainability, security …
orchestration of services flexible connection of individual services for a defined purpose This can be done during the planning phase and/or at runtime.
physical world the totality of all actually existing items and individuals The real world corresponds to the physical world.

Software loaded or in memory is part of the physical world. The frame of reference of the totality in question must be defined.

plug & work setting up, modification or termination of interoperation between two or more involved parties with minimal effort The interoperability of those involved is assumed.

The minimum effort can vary depending on the state of the art. Plug & play and plug & produce are synonyms or similar terms.

process entirety of procedures in a system by means of which the material, energy or information is transformed, transported or stored
Quality of Service (QoS) Performance of end-to-end communication between different partners
reference architecture model for a description of the architecture (for I4.0) which is used generally and is recognized as appropriate (with the character of a reference) A reference architecture can be defined on the basis of a reference model.
requirement specification of required criteria The system can fulfill the required criteria step-by-step, if necessary.
service demarcated scope of functionality which is offered by an entity or organization via interfaces One or multiple operations can be assigned to one service
service consumer entity or organization that consumes the service of a provider
service orientation paradigm which enables the straightforward exchange, addition or removal of loosely coupled services
service provider entity or organization that provides a service An entity or an organization can be a consumer and a provider (both at the same time).
skill of an I4.0 component potential of an Industrie 4.0 component to achieve an effect within a domain Skill can be orchestrated and hierarchically structured.

Capability is often used as synonym to skill. Skills can be made executable via services. The impact manifests in a measurable effect within the physical world.

smart product produced or manufactured (intermediate) product which in a smart factory delivers the (outward) communication capability to network and to interact intelligently with other production participants The product is a produced or manufactured article or semi-finished product.

A digital image is part of the product intelligence and can be localized on the product itself but also spatially separate from it. Unique identification and product-related information makes it possible for the product to be linked to the smart factory.

Software Development Kit (SDK) a set of software development tools that allows the creation of applications for a certain software framework, hardware platform, or similar development platform.
