Description of Commands
SHO R
Use the SHO R command to show Report settings and to program SER Points
and Aliases. You can also show event report parameters and program Event
Report Digital Elements. There is only one instance for the Report settings.
SHO T
Use the SHO T command to show aliases for Relay Word bits or analog
quantities. There is only one instance for the alias settings.
SNS
In response to the SNS command, the relay sends the names of the Sequential
Events Recorder elements. This is a comma-delimited string used to support
the SEL Fast SER report.
STATUS
The STATUS command reports relay status information that the relay derives
from internal diagnostic routines and self-tests. See Relay Self-Tests on
page P.11.38 for information on relay diagnostics.
STA
The STA command with no options displays a short-form relay status report.
Items in the STA report are the header, failures, warnings, SEL
OGIC control
equation programming environment errors, and relay operational status. See
Checking Relay Status on page P.10.10 for information on relay status reports.
If you change an I/O interface board, the relay detects the new configuration
and initiates a status warning. When you issue the STA command at Access
Level 2, the relay responds to this situation,
Accept new hardware
configuration (Y/N)?
If you answer Y <Enter>, the relay responds, New
configuration accepted
. If you answer N <Enter>, the relay responds,
Command aborted.
