Description of Commands
CBR TERSE
The CBR TERSE command omits the breaker report labels.
CEVENT
The CEVENT command provides a Compressed ASCII response similar to
the EVENT command. See Section 5: SEL Communications Protocols for
information on the Compressed ASCII command set. For detailed examples of
the items in the Compressed ASCII event report, see CEVENT on
page A.3.24.
CEV
Use the CEV command to gather relay event reports. When parameter n is 1
through 9999, n indicates the order of the event report. The most recent event
report is 1, the next most recent report is 2, and so on. When parameter n is
10000 through 42767, n indicates the absolute serial number of the event
report.
CEV ACK
Use CEV ACK to acknowledge viewing the oldest unacknowledged event on
the present communications port. View this event with the CEV NEXT or
EVE NEXT commands.
