MOV - Measuring equipment for electromagnetic quantities

IEC 61512-1:2026 applies to systems, specifications, and their use for implementing batch and related procedure-oriented manufacturing controls in the process industries. This document establishes a reference model framework for procedure-oriented control, defines terms to help explain the model relationships and usage, and describes general criteria for evaluating conformance. This follows the principle of separation between recipe procedural elements and equipment procedural elements enabling operations to define recipes without the need of changes in equipment procedures.
This second edition cancels and replaces the first edition published in 1997. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Models and text are modified to provide more detail and clarity. Key clarifications are:
1) Two types of equipment modules are defined: generic and recipe-aware. All recipe-aware equipment modules contain procedural control and can be used as phases in the recipe.
2) Execution of all procedural control contained directly in units is part of the Unit Supervision activity.
3) The relationships between types of recipes, recipe components, and equipment control are more fully described and illustrated.
4) Entity relationship diagrams have been replaced with more intuitive UML instance diagrams, except for the equipment entity model.
5) The transition diagram for the procedural states example has been updated with a more intuitive and complete UML state diagram.
6) References to other standards in the series and to IEC 62264 are included to provide direction for further clarification of selected topics.
7) Activity names are capitalised to help prevent confusion with similar terms, such as their underlying functions.
b) Previous Clauses 4 through 6 (now Clauses 4 through 8) were rearranged to provide a clearer top-down organisation of the document. Key changes are:
1) Removing the lower levels of the physical (role-based equipment) model (see 4.4.2) to eliminate redundancy because their groupings are defined by the associated functionality in the equipment entity model and are not meaningful for batch control without those associations.
2) Describing equipment control and the equipment entity model immediately after the physical (role-based equipment) model and describing each level as completely as possible without excessive use of forward references (see 4.4.3).
3) Combining the descriptions of basic, procedural, and coordination control with their usage in each type of equipment entity, providing a single consolidated discussion of each type of control (see Clause 5)
4) Additional considerations to support application of the models have been grouped in Clause 7 to clarify their supporting relationship to the core models.
c) Clause 9 was added to define completeness, compliance, and conformance in relation to this document.
d) Annex B was added to provide a more expansive procedural state reference model. The model found in Clause 7 can be considered a collapsed version of this more general model.
e) Annex C was added to clarify a number of points concerning the models, their application, and the new Clause 9 on conformance and compliance.
f) Annex E was added to more fully describe the changes in this update to IEC 61512-1:1997.

IEC 62541-2:2026 describes the OPC Unified Architecture (OPC UA) security model. It describes the security threats of the physical, hardware, and software environments in which OPC UA is expected to run. It describes how OPC UA relies upon other standards for security. It provides definition of common security terms that are used in this and other parts of the IEC 62541 series. It gives an overview and concept of the security features that are specified in other parts of the series. It references services, mappings, and Profiles that are specified normatively in other parts of the 62541 series. It provides suggestions or best practice guidelines on implementing security. Any seeming ambiguity between this document and one of the other normative parts does not remove or reduce the requirement specified in the other normative part.
There are many different aspects of security that are addressed when developing applications. However, since OPC UA specifies a communication protocol, the focus is on securing the data exchanged between applications. This does not mean that an application developer can ignore the other aspects of security like protecting persistent data against tampering. It is important that the developers look into all aspects of security and decide how they can be addressed in the application. Common security features for industrial Controls are defined in IEC 62443-4-2 and OPC UA defined a relationship to them in Annex A.
This document is directed to readers who will develop OPC UA applications. It is also for end Users that wish to understand the various security features and functionality provided by OPC UA. It also offers some recommendations that can be applied when deploying systems. These recommendations are generic in nature since the details would depend on the actual implementation of the OPC UA applications and the choices made for the site security.
This edition cancels and replaces the third edition of IEC TR 62541-2, published in 2020.This edition constitutes a technical revision.

IEC 62541-16:2025 defines an Information Model. The Information Model describes the basic infrastructure to model state machines.
NOTE State Machines were dealt with in IEC 62541‑5:2020, Annex B. In newer versions of IEC 62541‑5 this Annex B was removed and replaced by this document

This part of IEC 62541 is part of the overall OPC Unified Architecture specification series and defines the information model associated with Aggregates.
Programmatically produced aggregate examples are listed in Annex A.

This part of IEC 62541 defines the Information Model associated with Programs in OPC Unified Architecture (OPC UA). This includes the description of the NodeClasses, standard Properties, Methods and Events and associated behaviour and information for Programs.
The complete AddressSpace model including all NodeClasses and Attributes is specified in IEC 62541-3. The Services such as those used to invoke the Methods used to manage
Programs are specified in IEC 62541-4.
An example for a DomainDownload Program is defined in Annex A.

IEC 62541-24:2026 specifies an OPC UA information model to expose information, at what dates and times specific actions are executed by the OPC UA Server. Those schedules can optionally also be manipulated via the information model.
The schedule defines on which dates they are active, and can also reference global calendars representing specific dates, for example public holidays. In addition, the schedule defines times and actions that will be executed at that time. The model defines writing Variables and calling Methods but can be extended to other actions as well.
The NamespaceUri for all NodeIds defined in this document is defined in Annex A.

IEC 62541-19: 2025 defines an Information Model of the OPC Unified Architecture. The Information Model describes the basic infrastructure to reference from an OPC UA Information Model to external dictionaries like IEC Common Data Dictionary or ECLASS.

This part of IEC 62541 defines the OPC Unified Architecture (OPC UA) Services. The Services defined are the collection of abstract Remote Procedure Calls (RPC) that are implemented by OPC UA Servers and called by OPC UA Clients. All interactions between OPC UA Clients and Servers occur via these Services. The defined Services are considered abstract because no particular RPC mechanism for implementation is defined in this document. IEC 62541-6 specifies one or more concrete mappings supported for implementation. For example, one mapping in IEC 62541-6 is to UA-TCP UA-SC UA-Binary. In that case the Services described in this document appear as OPC UA Binary encoded payload, secured with OPC UA Secure Conversation and transported via OPC UA TCP.
Not all OPC UA Servers implement all of the defined Services. IEC 62541-7 defines the Profiles that dictate which Services must be implemented in order to be compliant with a particular Profile.
A BNF (Backus-Naur form) for browse path names is described in Annex A.

IEC 62541-100:2025 defines the information model associated with Devices. This document describes three models which build upon each other as follows:
• The (base) Device Model is intended to provide a unified view of devices and their hardware and software parts irrespective of the underlying device protocols.
• The Device Communication Model adds Network and Connection information elements so that communication topologies can be created.
• The Device Integration Host Model finally adds additional elements and rules required for host systems to manage integration for a complete system. It enables reflecting the topology of the automation system with the devices as well as the connecting communication networks.
This document also defines AddIns that can be used for the models in this document but also for models in other information models. They are:
• Locking model – a generic AddIn to control concurrent access,
• Software update model – an AddIn to manage software in a Device.

j) addition of AssociatedWith ReferenceType.

IEC 62541-17:2025 provides a definition of AliasNames functionality. AliasNames provide a manner of configuring and exposing an alternate well-defined name for any Node in the system. This is analogous to the way domain names are used as an alias to IP addresses in IP networks. Like a DNS Server, an OPC UA Server that supports AliasNames provides a lookup Method that will translate an AliasName to a NodeId of the related Node on a Server. An aggregating Server can collect these AliasNames from multiple Servers and provide a lookup Method to allow Client applications to discover NodeIds on a system wide basis. An aggregating Server could also define AliasNames for Nodes in other Servers that do not support AliasNames. A GDS can be constructed that would automatically aggregate all AliasNames that are defined on any Server that has registered with the GDS. In this case, the GDS also provides the lookup mechanism for Clients at a well-known endpoint and address.

IEC 62541-12:2025 specifies how OPC Unified Architecture (OPC UA) Clients and Servers interact with DiscoveryServers when used in different scenarios. It specifies the requirements for the LocalDiscoveryServer, LocalDiscoveryServer-ME and GlobalDiscoveryServer.

IEC 61496-3:2025 specifies additional requirements for the design, construction and testing of non‑contact electro-sensitive protective equipment (ESPE) designed specifically to detect persons or parts of persons as part of a safety-related system, employing active opto-electronic protective devices responsive to diffuse reflection (AOPDDRs) for the sensing function. Special attention is directed to requirements which ensure that an appropriate safety-related performance is achieved. An ESPE can include optional safety-related functions, the requirements for which are given both in Annex A of this document and in Annex A of IEC 61496‑1:2020.
NOTE "Non-contact" means that physical contact is not required for sensing.
This document does not specify the dimensions or configurations of the detection zone and its disposition in relation to hazardous parts for any particular application, nor what constitutes a hazardous state of any machine. It is restricted to the functioning of the ESPE and how it interfaces with the machine.
AOPDDRs are devices that have either
- one or more detection zone(s) specified in two dimensions (AOPDDR-2D), or
- one or more detection zone(s) specified in three dimensions (AOPDDR-3D)
wherein radiation in the near infrared range is emitted by an emitting element(s). When the emitted radiation impinges on an object (for example, a person or part of a person), a portion of the emitted radiation is reflected to a receiving element(s) by diffuse reflection. This reflection is used to determine the position of the object.
Opto-electronic devices that perform only a single one-dimensional spot-like distance measure­ment, for example, optical proximity switches, are not covered by this document.
This document is limited to ESPE that do not require human intervention for detection. It is limited to ESPE that detect objects entering into or being present in a detection zone(s).
This document does not address those aspects required for complex classification or differentiation of the object detected.
This document does not address requirements and tests for outdoor application.
Excluded from this document are AOPDDRs employing radiation with the peak of wavelength outside the range 820 nm to 1 100 nm, and those employing radiation other than that generated by the AOPDDR itself. For sensing devices that employ radiation of wavelengths outside this range, this document can be used as a guide. This document is relevant for AOPDDRs having a minimum detectable object size in the range from 30 mm to 200 mm.
This document can be relevant to applications other than those for the protection of persons, for example, for the protection of machinery or products from mechanical damage. In those applications, different requirements can be appropriate, for example when the materials that are recognized by the sensing function have different properties from those of persons and their clothing.
This document does not deal with electromagnetic compatibility (EMC) emission requirements.

IEC 63270-1:2025 provides guidance on the functional structure model, procedure, method, interface of function blocks. It also offers guidance on data requirements for predictive maintenance of equipment, devices and systems for industrial automation applications.
Condition monitoring is not only within the scope of this document but can also be an important input for predictive maintenance.

IEC 61987-41: 2025 provides:
• a characterization for the integration of process analysers in the Common Data Dictionary (CDD),
• generic structures for operating lists of properties (OLOP) and device lists of properties (DLOP) of measuring equipment in conformance with IEC 61987-10,
• generic structures for Dynamic Data, e.g. for condition monitoring of process analysers.
The generic structures for the OLOP and DLOP contain the most important blocks for process analysers. Blocks pertaining to a specific equipment type will be described in the corresponding part of the IEC 61987 standard series. Similarly, equipment properties are not part of this document. Thus, OLOP, DLOPs and LOPDs for selected process analysers families will be found in the IEC CDD.

IEC 61800-9-2:2023 specifies energy efficiency indicators of power electronics (complete drive modules (CDM), input or output sub drive modules (SDM), power drive systems (PDS) and motor starters, all used for motor driven equipment.
This document is a group energy efficiency publication according to IEC Guide 119 and specifies the methodology for the determination of losses of the complete drive module (CDM), the sub drive module (SDM), the power drive system (PDS) and the motor system.
It defines IE and IES classes, their limit values and provides test procedures for the classification of the overall losses of the motor system.
Furthermore, this document proposes a methodology for the implementation of the best energy efficiency solution of drive systems. This depends on the architecture of the motor driven system, on the speed/torque profile and on the operating points over time of the driven load equipment. It provides a link for the energy efficiency evaluation and classification of the extended product.
