In online or offline mode, you can view and analyze data generated by triggered parameters as follows:
• Event recorder — The event recorder captures contextual data associated with the last 1024 events, listed
chronologically from most recent to oldest
• Oscillography — The oscillography waveform traces and digital states are used to provide a visual display of power
system and relay operation data captured during specific triggered events
Event records are viewable at software and device-specific levels. Access the former under Admin > Event Log > View.
Access the latter under Actual Values > Records > Event Record.
