CHAPTER 5: SETTINGS PRODUCT SETUPB90 LOW IMPEDANCE BUS DIFFERENTIAL SYSTEM – INSTRUCTION MANUAL 5-535OverviewIEC 61850 is a series of international standards and technical reports applicable to power utility automation systems. Itincludes semantics, abstract communication services, specific communication services, performance specifications,network engineering guidelines, configuration description methodologies, and engineering processes. The standardenables interoperability among intelligent electronic devices (IEDs) from different suppliers and interoperability amongsoftware configuration tools from different suppliers. Interoperability in this case is the ability for IEDs to operate on thesame network or communication path sharing information and commands, and for configuration tools to understandeach other's configuration files.The UR family supports a large subset of IEC 61850 features. These are detailed in the UR Family Communications Guideand include the information model, GOOSE publish, GOOSE subscribe, buffered report server, unbuffered report server, andManufacturing Message Specification (MMS) query, read, write, and control services. In addition, the URs and theirEnerVista UR Setup software support IEC 61850 Substation Configuration Language (SCL) file import/export and merging.Whereas prior UR releases used edition 1.0 of IEC 61850, this release uses edition 2.0, with certain modifications accordingto IEC/TR 61850-90-5. Only edition 2.0 61850 configuration tools can interoperate with edition 2.0 devices, such as the UR7.3x release. This UR release uses edition 2.0 SCL, which differs from edition 1.0 SCL. GSSE, fixed GOOSE, and fixed reportservices of previous releases are no longer supported, and thus UR devices of previous releases using these features haveto be converted to configurable GOOSE to communicate with a 7.3x or later device.Many settings of UR protection, control, and monitoring elements, that is to say elements that are not concerned with theIEC 61850 protocol, can nevertheless be accessed via IEC 61850. These settings are documented elsewhere in this Settingschapter. This section of the Settings chapter deals solely with the settings that configure the IEC 61850 protocol itself.The maximum number of simultaneous clients supported by the UR family is five.EnerVista setup for IEC 61850The EnerVista UR Setup software provides the interface to configure B90 settings for the IEC 61850 protocol. This sectiondescribes this interface. The software also supports import/export and merging of IEC 61850 Substation ConfigurationLanguage (SCL) files as documented in the UR Family Communications Guide.The IEC 61850 protocol configuration settings cannot be accessed through the UR front panel and are instead accessiblewith the EnerVista software, via MMS query, read, and write services, or via 61850 SCL file transfer. Accordingly, whereasother settings are presented in this manual as they appear on the front panel, IEC 61850 settings are presented as theyappear in the software. See the UR Family Communications Guide for MMS and SCL access. Note that if you update the IEC61850 settings in the EnerVista software by writing to them by MMS while the corresponding IEC 61850 panel is open inEnerVista, you need to close then open the panel in EnerVista for the correct readings to display.IEC 61850 protocol configuration settings are accessed through software panels that are selected either in the OnlineWindow area (see figure) or the Offline Window area in the EnerVista software.The EnerVista software also includes an interface that is compatible with firmware versions 5.0 to 7.2 to configuresubscribers. Use the Simplified GOOSE Configurator in the Offline Window area.
