Compressed ASCII Commands
SEL-387-0, -5 Relay
CEVENT Command
The CEV report contains every analog and digital element found in an EVE
report, and displays the information in Compressed ASCII format by sending:
CEV
[
DIF R
] [
n
S
x
L
y
[–[
w
]]
C
]
<Enter>
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:

<ETX>
where: The data is a summation of breaker information collected
since the last summary clear.
xxxx
= are the data values corresponding to the first line labels.
yyyy
= the 4-byte ASCII representation of the hex checksum for
the line.
Report Types:
Description
DIF
Display differential information for all the 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.
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.
