The number of records to read is specified between 0000 and 0020 (0 to 32
decimal) in the command. If this value is set to 0, the number of stored
records is returned but the IP address table records are not returned. The
response returns the actual number of records read.
The maximum number of records that can be stored in the IP address table is
returned. The maximum number of stored records is fixed at 0020 (32
records).
The number of IP address table records stored at the time the command is
executed is returned as a hexadecimal number.
The number of IP address table records specified in the number of records
parameter is returned. The total number of bytes in the IP address table
records is calculated as the number of records × 6 bytes/record. The configu-
ration of the 6 bytes of data in each record is as shown in the following dia-
gram.
FINS Node Address
Node address for communications via the FINS command (in hexadecimal).
IP Address
IP number used by TCP/IP protocol (in hexadecimal).
If the IP address table contains fewer records than the number specified in the
number of records parameter, all the records contained in the IP address
table when the command is executed will be returned and the command exe-
cution will end normally.
An error response will be returned if the IP address conversion method in the
system mode settings is set to the automatic generation method.
