[Stored value]
0: Receive processing has been completed successfully.
Other than 0: Error code (stored when the receive processing ended in an
error)
▪ Results are overwritten when receive processing is conducted again.
▪ Error codes are also stored in the error log area.
[Stored value]
Size of the transparent receive data remaining in the ET-LAN unit (in byte units)
▪ Receive processing for this amount of data is finished successfully and
receive requests will be accepted even if the connection is closed.
[Stored value]
Copy of the size of the transparent receive data remaining in the ET-LAN unit
(in byte units)
▪ The same value as the transparent receive unnotified data size above is
stored.
▪ When the two values match, the size of the transparent receive data will be
fixed, so after they match, send a receive request using this value.
[Stored value]:
Size of the data actually received for the receive request in transparent
communication (in byte units)
▪ It is not possible for this value to be notified as exceeding the receive request
data size.
▪ When the connection has been closed, receive processing may end in some
cases even if the receive request data size has not been satisfied. If this
happens, the value is notified as being less than the receive request data size.
[Stored value]
0: Transmission processing has been completed successfully.
Other than 0: Error code (when transmission processing ended in an error)
▪ Results are overwritten when transmission processing is conducted again.
▪ Error codes are also stored in the error log area.
[Stored value]
Size of the data actually sent to the destination node for the transmission
request in transparent communication (in byte units)
▪ It is not possible for this value to be notified as exceeding the transmission
request data size.
▪ When the connection has been closed by the destination node during the
transmission, the transmission may be aborted. If this happens, this value is
notified as being less than the transmission request data size.
▪ When close processing is requested by the source node during the
transmission, the transmission processing is conducted first, and then close
processing is conducted.
▪ Even if the transmission processing ends in an error for some reason,
transmission processing of the data of the size corresponding to the value is
completed successfully.
