start or restart a session. When the client is able to receive the actual values
and when the logical device has scanned all process values at least once, an
image of the actual process signal status can be transmitted to the client.
Link BRCB to a client LN
The BRCB has to know to whom the events shall be transmitted. This is the signal
routing engineering step. The IEC standard 61850–6 describes that this is given by
including the LN of the client IED in the ReportBlockEnabled option.
The selected client IED with the corresponding LN, for example, ITCI is included in
the SCL structure of the Report Control description of the IED section.
The description of the BRCB with the selected data set, configured parameters and
selected IEDs is included in the SCL file in the IED section in the LN0 structure for
the LD where this LN0 belongs to.
