11.4.4 Error codes stored in the buffer memory
When an error occurs at each data communication processing between the Ethernet
module and an external device, the error code (abnormal code) is stored in the buffer
memory of the Ethernet module. This section explains the contents of this type of
errors and error handling procedures.
The "Storage destination" column in the error code list indicates the buffer memory
where the applicable error code is stored.
The names used for the explanation indicated in the "Storage destination" column
corresponding to the buffer memory error code storage areas shown in the table
below. (Error codes whose storage destination is not written are returned to the
external device.)
Note that the buffer memory may store error codes of the messages returned from the
external device. For error codes not shown in this manual, refer to the manual of the
external device and check the returned messages.
