FINS Commands Section 5-3
Comments An end code of 1103 hex (address range overflow) will be returned if the
beginning record number is higher than the number of records contained in
the PLC.
When the PLC does not have the specified number of records, all the records
that have been stored in the PLC will be read and a normal response will be
returned.
If the data is too large and exceeds the permissible length of the response for-
mat, the part in excess will not be read and a normal response will be
returned.
The following rules apply to records stored in the access log.
• If there is already a record for the same node, the old record will be over-
written with a new one.
• If there is not already a record for the same node, a new record will be
created at the end of the log.
• If the log is full (i.e., 20 records have already been stored), the oldest
record will be discarded and a new record will be created.
