Name
Stored value and Explanation
C
Transparent
receive unnotified
data size copy
(connections 1 to 8)
[Stored value] Copy of the size of the transparent received data
remaining in the ET-LAN unit (in bytes).
-
The same value as the transparent receive unnotified data size
above is stored.
-
If 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.
D
Transparent
receive notified
data size
(connections 1 to 8)
[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.
-
If 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, this value is notified as being less than
the receive request data size.
E
Transparent
transmission
processing
complete code
(connections 1 to 8)
[Stored value] 0: Transmission processing has been completed
successfully.
Other than 0: Error code (when transmission processing ended in an
error)
-
If transmission processing is carried out again, the results are
overwritten.
-
Error codes are also stored in the error log area.
F
Transparent
transmission
complete data size
(connections 1 to 8)
[Stored value] Size of the data actually sent to the partner 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.
-
If the connection has been closed by the partner 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.
-
If close processing is requested by the source node during the
transmission, the transmission processing is carried out first, and
then close processing is carried out.
-
Even if the transmission processing ends in an error for some
reason, transmission processing of the size of data corresponding
to this value is completed normally.
