SEL-551 Relay Instruction Manual Date Code 20110408
Compressed ASCII Commands
CHISTORY Command—SEL-551
CHISTORY Command—SEL-551
Display history data in Compressed ASCII format by sending:
CHI <CR>
The SEL-551 sends:
<STX>"REC_NUM","MONTH","DAY","YEAR","HOUR","MIN","SEC","MSEC",
"EVENT","SHOT","CURR","TARGETS","1539"<CR>
xxxx,xxxx,xxxx,xxxx,xxxx,xxxx,xxxx,xxxx,"xxxx",xxxx,xxxx,"xxxx","yyyy"<CR>
<ETX>
(the last line is then repeated for each record)
CEVENT Command—SEL-551
Display event report in Compressed ASCII format by sending:
CEV [n x] <CR>
The parameters in brackets, [ ], are optional.
The SEL-551 responds to the CEV command with the nth event report as
shown below:
<STX>"MONTH","DAY","YEAR","HOUR","MIN","SEC","MSEC","0ACA"<CR>
xxxx,xxxx,xxxx,xxxx,xxxx,xxxx,xxxx,"yyyy" <CR>
"IA","IB","IC","IN","IG","TRIG","RLY_BITS","0996"<CR>
xxxx,xxxx,xxxx,xxxx,xxxx,"z","xxxx","yyyy" <CR>
<ETX>
(the fourth line is then repeated for each data line in record one)
where:
xxxx = the data values corresponding to the first line labels
yyyy = the 4-byte hex ASCII representation of the checksum
n = the number of the event report, as used in the EVE
command
x = L specifies long event report, as used in the EVE command
x = R specifies raw (unfiltered) analog data, as used in the EVE
command
where:
xxxx = the data values corresponding to the first and third line
labels
yyyy = the 4 byte hex ASCII representation of the checksum
z = > for the trigger record and empty for all others
TRIG refers to the event trigger record indication
RLY_BITS refers to the Relay Word bits
