SEL-551 Relay Instruction Manual Date Code 20110408
Configuration, Fast Meter, and Fast Operate Commands
Message Definitions
ID Message
In response to the ID command, the relay sends the following:
<STX>"FID STRING ENCLOSED IN QUOTES","yyyy" <CR>
"BFID STRING ENCLOSED IN QUOTES","yyyy" <CR>
"CID STRING ENCLOSED IN QUOTES","yyyy" <CR>
"DEVID STRING ENCLOSED IN QUOTES","yyyy" <CR>
"DEVCODE STRINGENCLOSED IN QUOTES","yyyy" <CR>
"PARTNO STRING ENCLOSED IN QUOTES","yyyy" <CR>
"CONFIG STRING ENCLOSED IN QUOTES","yyyy" <CR>
"SPECIAL STRING ENCLOSED IN QUOTES","yyyy" <CR>
<ETX>
The ID message is available from Access Level 1 and higher.
DNA Message
In response to the DNA command, the relay sends names of the Relay Word
bits transmitted in the A5D1 message. The first name is associated with the
MSB, the last name with the LSB. The DNA message for the SEL-551 is:
<STX>"EN","INST","A","B","C","N","RS","LO","07A5"
"51P1","51P2","51N1","51G1","51P1T","51P2T","51N1T","51G1T","0BF4"

"PDEM", "NDEM", "GDEM", "QDEM", "TRGTR", "*", "*", "*", "0A1F"
"*", "*", "*", "*", "*", "*", "*", "*", "04D0"<ETX>
The DNA command is available from Access Level 1 and higher.
BNA Message
In response to the BNA command, the relay sends names of the bits
transmitted in the Status Byte in the A5D1 message. The first name is the
MSB, the last name is the LSB. The BNA message is:
<STX>"*","*","*","STSET","*","*","*","*","0639"<ETX>
The BNA command is available from Access Level 1 and higher.
where:
<STX> = the STX character (02)
<CR> = the carriage return character (13)
<ETX> = the ETX character (03)
DEVCODE = the string containing the Modbus
