Online and Offline Setup
ONLINE SETTINGS FILE
Two options are available to configure the relay's online settings file.
1. Configuration
– Configure the 845 (having order code option: IEC 61850) through the Device Setup
or Quick connect screen.
– The IEC 61850 Configurator "tree" item is displayed after Maintenance. See figure
below.
– Launch the online IEC 61850 configurator screen, by double-clicking on the
IEC61850 Configurator "tree" item.
– Select the required settings from the different tab displays (in the configurator
screen) to complete the IEC 61850 configuration.
2. Online right-click option
– Select any online relay and right click on the selected "tree" item. More options
become available for selection, as shown in the next examples.
Example of Additional Options
Generate ICD file: The menu option generates a default ICD file with the respective
order code option and saves the file to the path the user has selected previously.
Read Device Settings: The menu option reads all the settings from the relay by TFTP
and creates an 845 file with extension *.CID. The created *.CID file consists of two
sections. A private section where all non IEC 61850 settings are available, and a public
section in which IEC 61850 related settings are implemented.
When creating a CID file using a 3rd party ICT/SCL tool, the user must ensure the following:
– The order code in the CID file must match the device order code if writing the CID
file directly into the relay (without using the EnerVista software). The "Desc" value
in communication settings of the CID file must match the relay's order code.
– The maximum allowed services must be equal or below the specified limits as in
ICD/CID.
– Configure Datasets only in "LLN0" logical node.
