APPENDIX E: COMPRESSED ASCII COMMANDS
I NTRODUCTION
The SEL-351P Recloser Control provides compressed ASCII versions of some of the relay’s
ASCII commands. The compressed ASCII commands allow an external device to obtain data
from the relay, in a format which directly imports into spreadsheet or database programs, and
which can be validated with a checksum.
The SEL-351P provides the following compressed ASCII commands:
Command
Description
CASCII Configuration message
CSTATUS Status message
CHISTORY History message
CEVENT Event message
CASCII C OMMAND – G ENERAL F ORMAT
The compressed ASCII configuration message provides data for an external computer to extract
data from other compressed ASCII commands. To obtain the configuration message for the
compressed ASCII commands available in an SEL relay, type:
CAS <CR>
The relay sends:
<STX>"CAS",n,"yyyy"<CR>
"COMMAND 1",ll,"yyyy"<CR>
"#H","xxxxx","xxxxx",......,"xxxxx","yyyy"<CR>
"#D","ddd","ddd","ddd","ddd",......,"ddd","yyyy"<CR>
"COMMAND 2",ll,"yyyy"<CR>
"#h","ddd","ddd",......,"ddd","yyyy"<CR>
"#D","ddd","ddd","ddd","ddd",......,"ddd","yyyy"<CR>
•
•
•
"COMMAND n",ll,"yyyy"<CR>
"#H","xxxxx","xxxxx",......,"xxxxx","yyyy"<CR>
"#D","ddd","ddd","ddd","ddd",......,"ddd","yyyy"<CR><ETX>
where: n is the number of compressed ASCII command descriptions to follow.
COMMAND is the ASCII name for the compressed ASCII command as sent by the
requesting device. The naming convention for the compressed ASCII commands is a
'C' preceding the typical command. For example, CSTATUS (abbreviated to CST) is
the compressed STATUS command.
ll is the minimum access level at which the command is available.
