Compressed ASCII Commands
SEL-387-6 Relay
The command parameters, all optional, can be entered in any order. They are:
CEVENT Winding
Report (Default)
If DIF is not specified in the command line, the default report is the winding
currents report. To obtain a report, send the following:
CEV <Enter>
The relay responds:

Report Types: Description
DIF Display differential information for the all elements.
R Displays raw (unfiltered) analog data and raw station battery
Displays preceding 1.5 cycles (including reports with “L” options)
Allows S4, S8, S16, S32, and S64
Defaults to S16 samples/cycle
(default) Display cosine filtered fundamental currents
on all windings and station battery averaged for 1 cycle
Report Options: Description
n Event number
Default to 1
S x Samples per cycle
x = 4 or 8 (See “R” option)
Default to 4 if S x not specified
L y Display first y cycles of event report
y = 1 – LER
Default to L15 if L y not specified
L y – Displays event report from cycle y to end of report
L y – w Displays event report from cycle y to cycle w
C Default to 8 samples/cycle (same as EVE C )
NOTE:
If Sx and/or Ly are given, they
override all other parameters.
NOTE:
The L and U parameters are
supported for consistency with the
SEL-321 Relay. The C parameter is
used for SEL-2020 compatibility.
where:
xxxx
= are the data values corresponding to the first line labels.
yyyy
= the 4-byte ASCII representation of the hex checksum for
the line.
z
= “>” to mark where the event was triggered, “*” to mark
the maximum current for the event, with the “*”
overriding the “>”.
RLY_BITS
= relay element data, in hex ASCII, corresponding to the
DIGITAL_ELEMENT_NAMES
SETTINGS
= text refers to the current settings of the relay as described
in the event report section.
NOTE:
DIGITAL_ELEMENT_NAMES
consists of the text strings
representing the names for the Relay
Word bits from the element store
visible to the user, excluding the first
two front-panel rows.
NOTE:
If the analog current input
names ( IAW1 , etc.) have been changed
via the Analog Input Labels global
settings, they will appear in the above
report as set.
