ASCII Command Reference
Description of Commands
SET P
Use the SET P command to configure the relay communications ports; each
port is a settings instance. The SEL-421 communications ports include serial
ports at PORT F, PORT 1, PORT 2, and PORT 3. PORT 5 is the communications card
port into which the optional Ethernet card or other communications cards can
be installed.
SET R
Use the SET R command to set Report settings and to program SER points
and aliases. You can also set event report parameters and program event report
digital elements. There is only one instance for the Report settings.
Report settings are a mix of traditional settings entry mode and text-edit entry
mode. See Making Simple Settings Changes on page U.4.13 for settings entry
methods for these modes.
SET T
Use the SET T command to set aliases for Relay Word bits and analog
quantities. There is only one instance for the alias settings.
SET TERSE
Use the TERSE option to inhibit the relay from sending the settings class or
instance readback when you end a settings session. SEL recommends that you
use the TERSE option sparingly; you should review the readback information
to confirm that you have entered the settings that you intended.
