IEC TR 61850-80-5:2026
Communication networks and systems for power utility automation - Part 80-5: Guideline for mapping information between IEC 61850 and IEC 61158-15
Scope: IEC 61850-80-5:2026, which is a Technical Report, specifies the mapping framework for building and configuring a system using both IEC 61850 and IEC 61158-6-15 (Industrial communication networks – Fieldbus specification, CPF Type 15, Modbus) protocols by utilizing gateways between IEC 61850 and IEC 61158-6-15 IEDs / subsystems. The objective is to enable operational run-time data exchange among these IEDs / subsystems, and to automate the configuration of a gateway as much as possible.
Please note that for the purposes of this document, "Modbus" is used to represent both serial Modbus (Modbus RTU) and IEC 61158-6-15 (Modbus TCP).
Within the capability of each protocol, some configuration attributes (IEC 61850-7-3:2010 and IEC 61850-7-3:2010/AMD1:2020 attributes with functional constraint CF) are also mapped in addition to the operational real-time data.
The frameworks specified in this document are based on the published standards and do not make any proposed changes to IEC 61850 or 61158-6-15. This standard does not specify any framework for an IEC 61850 IED to directly communicate with a Modbus IED and vice versa, except through a gateway.
This document does not mandate which data items that a particular IED will be supporting, regardless of whether the implementation uses Modbus or IEC 61850. Instead, this document provides a framework specifying how a gateway maps any given data item from Modbus into an IEC 61850 substation, including the control direction.
Similarly, this document does not mandate which mapping framework a given gateway will be supporting. When this document is republished as a Technical Specification, conformance requirements will be identified.
This document recognizes that there will be situations in which a user will require that a gateway perform non-standard protocol mappings. Non-standard mappings are outside the scope of this document.
This document also recognizes that gateways typically manipulate the data passing through them in a variety of ways. Some of these functions include alarm trigger grouping, data suppression, interlocking and command blocking. Conformance to this document does not preclude a gateway from performing such functions, even though this document primarily specifies "straight through" mapping of Modbus data to IEC 61850-7-3:2010 and IEC 61850-7-3:2010/AMD1:2020 data. Subclause 7.5 of this document describes how some of these functions can be specified to a gateway by a mapping tool using XML representations of conversion functions.
The mapping architecture for the exchange of the run-time information consists of four parts:
a) Conceptual architecture of a gateway and associated use case
b) Mapping of the information model (Assign semantic to the Modbus data)
c) Mapping of the data (which is in fact part of the information model)
d) Mapping of the services (out of scope for this document)
This second edition cancels and replaces the first edition published in 2024. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) deficiencies / missing text in Edition 1 corrected.

IEC 61000-6-3:2020
Electromagnetic compatibility (EMC) - Part 6-3: Generic standards - Emission standard for equipment in residential environments
Scope: IEC 61000-6-3:2020 is a generic EMC emission standard applicable only if no relevant dedicated product or product family EMC emission standard has been published. This part of IEC 61000 for emission requirements applies to electrical and electronic equipment intended for use at residential (see 3.1.14) locations. This part of IEC 61000 also applies to electrical and electronic equipment intended for use at other locations that do not fall within the scope of IEC 61000-6-8 or IEC 61000-6-4. The intention is that all equipment used in the residential, commercial and light-industrial environments are covered by IEC 61000-6-3 or IEC 61000-6-8. If there is any doubt the requirements in IEC 61000-6-3 apply. The conducted and radiated emission requirements in the frequency range up to 400 GHz are considered essential and have been selected to provide an adequate level of protection of radio reception in the defined electromagnetic environment. Not all disturbance phenomena have been included for testing purposes but only those considered relevant for the equipment intended to operate within the locations included within this document. The emission requirements in this document are not intended to be applicable to the intentional transmissions and their harmonics from a radio transmitter as defined by the ITU. This third edition cancels and replaces the second edition published in 2006 and its Amendment 1:2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) alternative method for measuring conducted emissions on DC ports;
b) limits and requirements applicable only to equipment intended to be used in residential locations;
c) more stringent limits for DC power ports.
NOTE 1 Safety considerations are not covered by this document.
NOTE 2 In special cases, situations will arise where the levels specified in this document will not offer adequate protection; for example where a sensitive receiver is used in close proximity to an equipment. In these instances, special mitigation measures can be employed. NOTE 3 Disturbances generated in fault conditions of equipment are not covered by this document.
NOTE 4 As the requirements in this document are more stringent or equivalent to those requirements in IEC 61000-6-4 and IEC 61000-6-8, equipment fulfilling the requirements of this document comply with the requirements of IEC 61000-6-4 and IEC 61000-6-8.

IEC TR 61850-80-5:2024
Communication networks and systems for power utility automation - Part 80-5: Guideline for mapping information between IEC 61850 and IEC 61158-15
Scope: IEC TR 61850-80-5:2024, which is a Technical Report, specifies the mapping rules for building and configuring a system using both IEC 61850 and IEC 61158-6 (Industrial communication networks - Fieldbus specification, CPF Type 15, Modbus) protocols by utilizing gateways between IEC 61850 and IEC 61158-6 IEDs / subsystems. The objective is to enable operational run-time data exchange among these IEDs / subsystems, and to automate the configuration of a gateway as much as possible.
Please note that for the purposes of this document, "Modbus" is used to represent both serial Modbus (Modbus RTU) and IEC 61158-6 (Modbus TCP).
Within the capability of each protocol, some configuration attributes (IEC 61850-7-3:2010+AMD1:2020 attributes with functional constraint CF) are also mapped in addition to the operational real-time data.
The rules specified in this document are based on the published standards and do not make any proposed changes to IEC 61850 or 61158-6. This standard does not specify any rules for an IEC 61850 IED to directly communicate with a Modbus IED and vice versa, except through a gateway.
This document does not mandate which data items that a particular IED shall support, regardless of whether the implementation uses Modbus or IEC 61850. Instead this document provides rules specifying how a gateway maps any given data item from one protocol to the other, given that the data item is already available and is transmitted using one of the protocols.
Similarly, this document does not mandate which mapping rules a given gateway shall support. When this document is republished as a Technical Specification, conformance requirements will be identified.
This document recognizes that there will be situations in which a user will require that a gateway perform non-standard protocol mappings. Non-standard mappings are outside the scope of this document.
This document also recognizes that gateways typically manipulate the data passing through them in a variety of ways. Some of these functions include alarm trigger grouping, data suppression, interlocking and command blocking. Conformance to this document does not preclude a gateway from performing such functions, even though this document primarily specifies "straight through" mapping of Modbus data to IEC 61850-7-3:2010+AMD1:2020 data. Subclause 7.4 of this document describes how some of these functions may be specified to a gateway by a mapping tool using equation notation in XML. However, some of these functions may be too complex for a mapping tool to specify in an automated manner.
The mapping architecture for the exchange of the run-time information consists of four parts:
1) Conceptual architecture of a gateway and associated use case
2) Mapping of the information model (Assign semantic to the Modbus data)
3) Mapping of the data (which is in fact part of the information model)
4) Mapping of the services (out of scope for this document)

Optical fibre cables - Part 1-113: Generic specification - Basic optical cable test procedures - Mechanical tests methods - Shotgun resistance, Method E13
Scope: This part of IEC 60794 describes test procedures used to establish uniform requirements for optical fibre cables on their mechanical properties— Shotgun resistance.
This document applies to optical fibre cables for use with telecommunication equipment and devices employing similar techniques, and to cables having a combination of both optical fibres and electrical conductors.
This document defines test procedures to be used in establishing uniform requirements for mechanical requirement performance by describing two test procedures to determine the ability of optical cables to withstand damages caused by shotgun.
This document generically applies to aerial optical cables that are suitably designed for shotgun protection and addresses cables constructions such as all-dielectric self-supporting cables (ADSS), optical attached cables (OPAC) as described in [1], or Figure-8 aerial optical cables as described in [2].
NOTE  Most cables may not be subjected to this test. Due to the wide range of possible variations in this test, this test is considered as a specialty test for very specific applications. Damage to cables caused by shotguns or other  
firearms is an occasional occurrence.

Equipment for general lighting purposes - EMC immunity requirements
Scope: This part of IEC 61547 which deals with electromagnetic immunity requirements, applies to lighting equipment which is within the scope of IEC technical committee 34, including apparatus such as lamps, luminaires, controlgear for electric light sources, and end-user replaceable modules like non-integrated and semi-integrated LED lamps and LED modules.
Lighting equipment with a wireless control function are also within the scope of this document. However, the test is limited to the control of the lighting function only. Radio properties like frequency stability or spurious emissions are not assessed.
EXAMPLE Colour/light level control via a wireless interface are meant to stay intact during and after an immunity test.
Also included in the scope of this document is lighting equipment that interfaces with systems or installations other than common power supply networks.  
Excluded from the scope of this document are:
– components or modules designed to be integrated into lighting equipment but not intended for end-user replacement.
– equipment for which the electromagnetic compatibility requirements in the radio-frequency range are explicitly formulated in other product immunity standards, even if they incorporate a built-in lighting function.
NOTE 1 Examples of exclusions are: – equipment with built-in lighting devices for display back lighting, scale illumination and signaling;
– SSL-displays;
– range hoods, refrigerators, freezers; – photocopiers, projectors;
– electronic switches for fixed installations;
– lighting equipment for road vehicles (within the scope of CISPR 12);
– lighting equipment for aircraft and airfield facilities.
NOTE 2 Modules that are not end-user replaceable are not in the scope of this document but can be tested according to this document for information purposes (for instance, of luminaire manufacturers).
In multi-function equipment where the lighting function operates independently from other functions, the electromagnetic immunity requirements of this document apply to the lighting function only.
The requirements of this document are based on the generic immunity standard for residential, commercial and light-industrial environments IEC 61000-6-1:2016, but modified to lighting engineering practice.
It can be expected that lighting equipment complying with the requirements of this document will operate satisfactorily in other environments. In some special cases, measures can be taken to provide higher immunity. In this document it is impracticable to deal with all these possibilities.  
Such requirements can be established by contractual agreement between supplier and purchaser.
This document does not cover the effects that electromagnetic disturbances have on the lifetime of lighting equipment.
