PD 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
This part of IEC 61850, 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.
