Special function buffer full
An attempt by the application to register a special memory
read/write function was rejected because the buffer was full.
Extended
DNP
Special function registered
(Action 1=read 2=write, Memory
Address, N/A, N/A)
A special function related to a specific memory action and
virtual memory address was successfully added to the list.
Extended
DNP
Transient peer add failed (Source
Address, Application Control,
N/A, N/A)
The source of this fragment was unknown so an attempt
was made to add it to the peer device list. The attempt was
unsuccessful so the fragment was discarded.
Extended
DNP
Transmit fragment buffer full
No free buffer was found in the transport function transmit
buffers. The application layer may save this message and
reattempt to transmit.
Extended
DNP
