Internal table
This is a table of correspondences for remote FINS node addresses, remote IP
addresses, TCP/UDP, and remote port numbers. It is created automatically when power is
turned ON to the PLC or when the unit is restarted, and it is automatically changed when
a connection is established by means of the FINS/TCP method or when a FINS command
received.
The following functions are enabled by using this table.
•
IP address conversion using the FINS/UDP method
•
Automatic FINS node address conversion after a connection is established using the
FINS/TCP method
•
Automatic client FINS node address allocation using the FINS/TCP method
