SYSTEM SETUP
5.5.7.6 Configuration example: CFG-2 based configuration (using IEC 61850-90-5)
The F60 is expected to send the CFG-2 file (IEEE C37.118 config. file) upon request from the upstream synchrophasor
devices (for example, P30) without stopping R-SV multicasting, as shown in the following figure. The primary domain
controller (PDC) does not need to use a stop/start data stream command if the UR protocol is set to IEC 61850-90-5 prior to
5
requesting the configuration via CFG-2 (IEEE C37.118 config. file). The CFG-2 request from the P30 can be on TCP/IP or
UDP/IP, however, R-SV data streaming is only UDP multicasts (not TCP).
5.5.7.7 Modification of SYNC word in CFG-2 for TR 90-5 data sets
In the CFG-2 file, all relevant information about the data being streamed is included. However, this file does not include the
fact that it describes a 90-5 dataset or the number of Application Service Data Units (datasets). In order to communicate
this information via the CFG-2 file for a given aggregator, when the aggregator is set to 90-5, the version number of the
CFG-2 file (found in bits 0-3 of the frame SYNC word, which is set presently to 2) is set as follows:
Value (decimal)
