CONFIGURING THE UR USING SCL
3
An ICD file obtained from a UR 7.3 or later device or from EnerVista UR Setup software contains all of the settings in the
device at their factory default values. Unlike some IEDs that use several files to contain a complete set of settings, UR-
generated SCL files contain all of the device's settings. Settings related to IEC 61850 communications (such as GOOSE,
reports, datasets, commands, MMS queries) are in Public elements that can be understood and configured by SCTs. The
remainder of the settings are contained in a Private element that is not intended to be understood or modified by SCTs,
only by EnerVista UR Setup. A second Private element contains a "signature" of the first that allows any modifications of UR
Private setting data to be detected.
As these ICD files apply to all UR family devices with the same order code and firmware version, they can be given an
appropriate file name, saved in a templates database, and reused for each similar UR device in the system and in future
systems. However, starting the configuration from the factory default values for each of several similar UR devices
applications unnecessarily duplicates setting efforts. In these cases it is more efficient to begin with a "template" ICD file in
which the setting values that are the same of each application are preconfigured.
Pre-configured template ICD files can be obtained using EnerVista UR Setup software to create a settings file in its Offline
Window as described, but to then to continue to use EnerVista software to configure its protection and control settings for
a particular application type, for instance for a typical low voltage feeder. Some or all of its communications settings can
be configured as well. Next, right-click on the file name, select Create IID File, enter a name for the file. Such IID files are
the same as the ICD files previously described except that the settings are as modified by the EnerVista UR Setup user.
Finally, rename the IID file with a .icd extension and save it in the templates database.
The SCT merges all the imported SCL files into a single System Configuration Description (SCD), and completes the
communications configuration. For UR devices, this involves some or all of:
• Setting various configuration version parameters
• Giving the UR device a unique name
• Configuring the IP source address parameters
