Display history data in compressed ASCII format by typing:
CHI <CR>
The relay replaces the items in italics with the actual relay data.
The SEL-701 Relay sends:
<STX>"FID","yyyy"<CR>
"Relay FID string","yyyy"<CR>
"REC_NUM","MONTH","DAY","YEAR","HOUR","MIN","SEC","MSEC","TYPE","FREQ","THM
CAP(%)","UB_CURR(%)","IA","IB","IC","IN","IG","3I2","WDG (C)","BRG (C)","AMB (C)","OTH
(C)","VAB","VBC","VCA","kW","kVAR","kVA","PF","LD/LG","yyyy"<CR>
xxxx,xxxx,xxxx,xxxx,xxxx,xxxx,xxxx,xxxx,"xxxx",xxxx,xxxx,xxxx,xxxx,xxxx,xxxx,xxxx,
xxxx,xxxx,"xxxx","xxxx","xxxx","xxxx",xxxx,xxxx,xxxx,xxxx,xxxx,xxxx,xxxx,"xxxx",
"yyyy"<CR>
<ETX>
(the second line is then repeated for each record)
where:
 "xxxx" are the data values corresponding to the first line labels.
 "yyyy" is the 4-byte hex ASCII representation of the checksum.
 "THM CAP(%)" is the thermal model thermal capacity used in
percent.
If the history buffer is empty, the relay responds:
<STX>"No Data Available","0668"<CR>
<ETX>
If the relay does not support voltage measurement, the voltage and power labels
are replaced with “*”.
If the relay is not equipped with internal or external RTD inputs, the RTD labels
are replaced with: “*”. If Fahrenheit is the designated temperature scale, the
temperature designator (C) is replaced with (F).
