where
yyyy is the 4-byte ASCII representation of the hex checksum for the line.
The bits named are defined as follows:
STSET
Set when a power-up or settings change has occurred. It is cleared by the
A5B9 request (see earlier in this Appendix).
STFAIL
One or more of the monitored status quantities is in a FAIL state.
STWARN
One or more of the monitored status quantities is in a WARN state.
SNS Message
In response to the
SNS
command, the relay sends the name string of the SER (SER1, SER2,
SER3, and SER4) settings. The
SNS
command is available at Access Level 1.
The relay responds to the
SNS
command with the name string in the SER settings. The name
string starts with SER1, followed by SER2, SER3, and SER4.
For example: If SER1 = 50P11 OUT101; SER2 = 87U1 32IF; SER3 = OUT102 52A, SER4 = 0;
the name string will be "50P11","OUT101","87U1","32IF","OUT02","52A".
If there are more than eight settings in SER, the SNS message will have several rows. Each row
will have eight strings, followed by the checksum and cartridge return. The last row may have
fewer than eight strings.
The ALIAS settings are ignored for the
SNS
command (i.e., if ALIAS1 = OUT101 CL_BKR_1,
SNS includes "OUT101",
not
the custom label). Refer to
Settings
in
Section 6: Setting the
Relay.
SNS message for the SEL-387E is:
<STX>"xxxx","xxxx","xxxx","xxxx","xxxx","xxxx","xxxx","xxxx","yyyy"<CR>
"xxxx","xxxx","xxxx","xxxx","xxxx","xxxx","xxxx","xxxx","yyyy"<CR>
"xxxx","xxxx","xxxx",<CR><ETX>
where: xxxx is a string from the settings in SER (SER1, SER2, SER3, and SER4)
yyyy is the 4-byte ASCII representation of the checksum
