Message Definitions
A5ED Fast Operate
Reset Command
The Fast Operate Reset commands take the following form shown in
Table D.12.
ID Command
In response to the ID command, the relay sends the firmware ID (FID), boot
firmware ID (BFID), firmware checksum (CID), relay TID setting (DEVID),
Modbus
®
device code (DEVCODE)—for use by SEL-2032, SEL-2030, and
SEL-2020 Communications Processors, relay part number (PARTNO), and
configuration string (CONFIG)—for use by other IEDs or software. A sample
response is shown below; responses will differ depending on relay model,
settings, and firmware.
<STX>"FID=SEL 351A-R...-V0-Z002002-D2000….","yyyy"<CR><LF>
"BFID=SELBOOT-311-R….","yyyy"<CR><LF>
"CID=xxxx","yyyy"<CR><LF>
"DEVID=STATION A","yyyy"<CR><LF>
"DEVCODE=51","yyyy"<CR><LF>
"PARTNO=0351A00H14554x1","yyyy"<CR><LF>
"CONFIG=111122","yyyy"<CR><LF>
"SPECIAL=1","yyyy"<CR><LF><ETX>
The ID message is available from Access Level 0 and higher.
DNA Message
In response to the DNA command, the relay sends the 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. These names are listed in the Relay
Word Bits table for the appropriate model in Section 9: Setting the Relay. The
DNA command is available from Access Level 1 and higher.
