Communications
SEL ASCII Protocol and Commands
The elements are represented as Relay Word bits and are listed in rows of
eight, called Relay Word rows. The first four rows, representing the front-
panel operation and target LEDs, correspond to Table 7.56. All Relay Word
rows are described in Table J.1 and Table J.3.
Relay Word bits are used in SEL
OGIC
control equations. See Appendix J:
Relay Word Bits.
The TAR command does not remap the front-panel target LEDs, as is done in
some previous SEL relays.
TIME Command (View/Change Time)
The TIME command (see Table 7.57) returns information about the
SEL-700G internal clock. You can also set the clock if you specify hours and
minutes (seconds data are optional). Separate the hours, minutes, and seconds
with colons, semicolons, spaces, commas, or slashes.
Use the TIME hh:mm and TIME hh:mm:ss commands to set the internal
clock time. The value hh is for hours from 0–23; the value mm is for minutes
from 0–59; the value ss is for seconds from 0–59. If you enter a valid time, the
relay updates and saves the time in the nonvolatile clock, and displays the time
you just entered. If you enter an invalid time, the SEL-700G responds with
Invalid Time
.
TRIGGER Command (Trigger Event Report)
Use the TRI command (see Table 7.58) to trigger the SEL-700G to record
data for the high-resolution oscillography and event reports.
When you issue the TRI command, the SEL-700G responds with
Triggered
.
If the event did not trigger within one second, the relay responds with
Did not
trigger
. See Section 9: Analyzing Events for further details on event reports.
