Software Flow Control Message
The MPI 6000 after receiving command request messages from the host optionally
sends software flow control messages to the host as required for system operation.
The host optionally sends software flow control messages to the MPI 6000 as required
for host operation.
The host and the MPI 6000 uses the following UDP/IP fast Ethernet communications
software flow control message shown here:
<len> <msgSeqNum> <cmd> <cmdSeqNum> <resp> <checksum>
where
<len> = length, a word that specifies the number of bytes in the entire message.
<msgSeqNum> = message sequence number, a byte that specifies the message
sequence number of the message. See the software communication sequence number
controls section for details.
<cmd> = command, a word that specifies the system command. See the command
sections for details.
<cmdSeqNum> - command sequence number, a byte that specifies the command
sequence number of the message. See the software communication sequence number
controls section for details.
<resp> = response, a word that specifies the system response. See the response sec-
tions for details.
<checksum> = checksum, a byte that specifies the checksum of the message.
Unsolicited Status Message
The MPI 6000 sends unsolicited status messages to the host as required for system
operation.
The host and the MPI 6000 uses the following UDP/IP fast Ethernet communications
unsolicited status message shown here:
<len> <msgSeqNum> <cmd> <cmdSeqNum> <status> [<data>] <checksum>
where
<len> = length, a word that specifies the number of bytes in the entire message.
<msgSeqNum> = message sequence number, a byte that specifies the message
sequence number of the message. See the software communication sequence number
controls section for details.
<cmd> = command, a word that specifies the system command. See the command
sections for details.
<cmdSeqNum> = command sequence number, a byte that specifies the command
sequence number of the message. See the software communication sequence number
controls section for details.
