An ICD file is generated for the G60 by the EnerVista UR Setup software that describe the capabilities of the IED. The ICD file is then imported into a system configurator along with other ICD files for other IEDs (from GE or other ven- dors) for system configuration.
It can also import a system SCL file (SCD) to set communication configuration parame- ters (that is, required addresses, reception GOOSE datasets, IDs of incoming GOOSE datasets, etc.) for the IED. The IED configurator functionality is implemented in the GE Multilin EnerVista UR Setup software. C.5.2 CONFIGURING IEC 61850 SETTINGS Before creating an ICD file, the user can customize the IEC 61850 related settings for the IED.
Although configurable transmission GOOSE can also be created and altered by some third-party system con- figurators, we recommend configuring transmission GOOSE for GE Multilin IEDs before creating the ICD, and strictly within EnerVista UR Setup software or the front panel display (access through the Settings > Product Setup > Com- munications >...

Furthermore, it defines the capabilities of an IED in terms of communication services offered and, together with its LNType, instantiated data (DO) and its default or configuration values.

C.5.5 ABOUT SCD FILES System configuration is performed in the system configurator. While many vendors (including GE Multilin) are working their own system configuration tools, there are some system configurators available in the market (for example, Siemens DIGSI version 4.6 or above and ASE Visual SCL Beta 0.12).

The software will open the SCD file and then prompt the user to save a UR-series settings file. Select a location and name for the URS (UR-series relay settings) file. If there is more than one GE Multilin IED defined in the SCD file, the software prompt the user to save a UR-series set- tings file for each IED.
