E-2 Compressed ASCII Commands Date Code 20001006
SEL-351 Instruction Manual
#H identifies a header line to precede one or more data lines; '#' is the number of
subsequent ASCII names. For example, “21H” identifies a header line with 21 ASCII
labels.
#h identifies a header line to precede one or more data lines; '#' is the number of subse-
quent format fields. For example, “8h” identifies a header line with 8 format fields.
xxxxx is an ASCII name for corresponding data on following data lines. Maximum
ASCII name width is 10 characters.
#D identifies a data format line; '#' is the maximum number of subsequent data lines.
ddd identifies a format field containing one of the following type designators:
I Integer data
FFloating point data
mS String of maximum m characters (e.g., 10S for a 10 character string)
yyyy is the 4-byte hex ASCII representation of the checksum.
A compressed ASCII command may require multiple header and data configuration lines.
If a compressed ASCII request is made for data that are not available, (e.g. the history buffer is
empty or invalid event request), the relay responds with the following message:
<STX>"No Data Available","0668"<CR><ETX>
