The protection relay supports the IEC 61850 process bus with the IEC 61850-9-2 sampled values protocol. By default, if sampled values sending is enabled, relay sends 9-2LE conformant sampled values data. However, if modifying specific SMV options or attributes, the SMV data might not be according to 9-2LE specification anymore. PCM600 gives user a warning if the SMV stream configured is not according to 9-2LE. If SMV data is sent to e.g. 3rd party device, system engineer must ensure is the SMV receiving device is capable to e.g. handle specific SMV options.
