IEC 63316:2026 prescribes safeguards, test methods and compliance requirements intended to reduce the risk of electrical shock and fire associated with voltage and current at voltages greater than 60 V DC and 60 V AC. This document applies to equipment ports intended to supply and receive operating power from communications equipment ports using communication wires and cables. It covers particular requirements for circuits that are designed to transfer AC or DC power from a power sourcing equipment (PSE) (3.1.2) to a powered device (PD) (3.1.3), including repeaters, amplifiers, Optical Network Units, Remote DSLAMs, service provider terminating equipment, remote telecommunications cabinets and equipment, and midspan passive equipment connected to the PSE (3.1.2) and PD (3.1.3). The power transfer of equipment ports covered by this document uses non-mains AC voltage or non-mains DC voltage above 60 V DC classified as ES2 according to 5.2.1.2 of IEC 62368-1:2023 or, in some very controlled cases, classified as ES3 according to IEC 62368-1:2023. EXAMPLES - DC power transfer using voltages above 60 V DC but ≤ 120 V DC, classified as ES2; - Some telecommunications networks where the voltage was formerly called TNV-3 (see IEC 62368-1:2023, Table W.3), typically used for line, span or express powering outside North America, Long Range Reverse Power Feeding, HDSLx line powering ISDN, Line Powering Primary Rate E1; - Some North American telecommunications networks between the utility service providers´ PSE (3.1.2) and service providers side of the PD (3.1.3) at the PNI (3.1.8); - For DC power transfer using voltages ≥ 120 V DC at ES3: RFT circuits and the associated telecommunications network equipment and cabling used by communications service providers and communications utilities (for example, line powered E1/T1, HDSLx, SHDSLx, xDSL, repeaters, and telecommunications line powering up or line powering down converters as applicable), Optical Network Units, remote DSLAMs, etc. These RFT circuits are used between the utility service providers PSE (3.1.2) and service providers side of the PD (3.1.3) at the PNI (3.1.8). The customer facing ports of this equipment are at voltage not exceeding 60 V DC and are covered by IEC 62368-1:2023, see Annex A for deployment topologies; - For AC/DC remote powering voltage above ES1 over coaxial cable in circuits used by cable television utility service providers for repeaters, amplifiers, Optical Network Units. The customer facing ports of this equipment are at voltage not exceeding 60 V DC that are covered by IEC 62368-1:2023. NOTE 1 Any communications cable that permits power transfer between communication equipment is considered a communication cable even if communication does not take place. For example, a line powering up or line powering down converters as applicable used to power remote telecommunications equipment, can provide limited communications RFT power and not necessarily any superimposed data or signalling.

The present document contains the common requirements for marine radio communications and radio determination equipment and associated ancillary equipment operating from any combination of internal batteries, DC and single phase AC, in respect of ElectroMagnetic Compatibility (EMC). The provisions of the present document apply to marine radio equipment not covered in the scope of the Council Directive on marine equipment (the "Marine Equipment Directive" 2014/90/EU [i.4]). Product dependent arrangements necessary to perform the EMC tests on dedicated types of marine radio communications and radio determination equipment, and the assessment of test results, are detailed in the appropriate product related parts of the present document. The present document, together with the product related part, specifies the applicable EMC tests, the methods of measurement, the limits and the performance criteria for marine radio equipment and associated ancillary equipment. In case of differences (for instance concerning special conditions, definitions, abbreviation) between the present document and the relevant product related part of the present document, the product related part takes precedence. For the further content of the present document, the expression "radio equipment" is taken to mean marine radio communications or radio determination equipment, in each individual case. Technical specifications related to the antenna port of radio equipment and emissions from the enclosure port of radio equipment and combinations of radio and associated ancillary equipment are not included in the present document. Such technical specifications are normally found in the relevant product standards for the effective use of the radio spectrum. The environment classification used in the present document is maritime, as defined in EN IEC 60945 [i.3]. Marine radio communications equipment meeting the EMC requirements set out in EN IEC 61000-6-3 [i.1] and EN 61000-6-1 [i.2] is deemed to meet also the EMC requirements for the maritime environment described in EN IEC 60945 [i.3]. The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus intended to be used in the maritime environment. The levels, however, do not cover extreme cases which may occur in any location but with low probability of occurrence.

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)

NOTE 4: Rationale is that even if antenna characteristics are not relevant for access to radio spectrum of MP fixed radio systems (see technical description in ETSI TR 101 506 [i.6]), the essential equipment parameters are defined at antenna port and their radiated test procedures are not available. For information, the most common types of antennas are standardized in Part 3 of this multi-part
deliverable [i.2]. Systems referring to an EqC with "H" code (see clause C.2.2) as Primary Equipment Classification (PET), implementing an actual FH-CDMA access method with frequency hopping period exceeding 400 ms, are not considered within the scope of the present document. Applications intended for offering in the bands 3,4 GHz to 3,8 GHz the option of Nomadic Wireless Access (NWA), according to the NWA definition in Recommendation ITU-R F.1399 [i.14], are not considered in the scope of the present document.

IEC 63316:2026 prescribes safeguards, test methods and compliance requirements intended to reduce the risk of electrical shock and fire associated with voltage and current at voltages greater than 60 V DC and 60 V AC.
This document applies to equipment ports intended to supply and receive operating power from communications equipment ports using communication wires and cables. It covers particular requirements for circuits that are designed to transfer AC or DC power from a power sourcing equipment (PSE) (3.1.2) to a powered device (PD) (3.1.3), including repeaters, amplifiers, Optical Network Units, Remote DSLAMs, service provider terminating equipment, remote telecommunications cabinets and equipment, and midspan passive equipment connected to the PSE (3.1.2) and PD (3.1.3).
The power transfer of equipment ports covered by this document uses non-mains AC voltage or non-mains DC voltage above 60 V DC classified as ES2 according to 5.2.1.2 of IEC 62368-1:2023 or, in some very controlled cases, classified as ES3 according to IEC 62368-1:2023.
EXAMPLES
- DC power transfer using voltages above 60 V DC but ≤ 120 V DC, classified as ES2;
- Some telecommunications networks where the voltage was formerly called TNV-3 (see IEC 62368-1:2023, Table W.3), typically used for line, span or express powering outside North America, Long Range Reverse Power Feeding, HDSLx line powering ISDN, Line Powering Primary Rate E1;
- Some North American telecommunications networks between the utility service providers´ PSE (3.1.2) and service providers side of the PD (3.1.3) at the PNI (3.1.8);
- For DC power transfer using voltages ≥ 120 V DC at ES3: RFT circuits and the associated telecommunications network equipment and cabling used by communications service providers and communications utilities (for example, line powered E1/T1, HDSLx, SHDSLx, xDSL, repeaters, and telecommunications line powering up or line powering down converters as applicable), Optical Network Units, remote DSLAMs, etc. These RFT circuits are used between the utility service providers PSE (3.1.2) and service providers side of the PD (3.1.3) at the PNI (3.1.8). The customer facing ports of this equipment are at voltage not exceeding 60 V DC and are covered by IEC 62368-1:2023, see Annex A for deployment topologies;
