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
• Simultaneous connection of multiple FINS applications
