Items set for each UDP port
• Broadcast
• Address conversion method
Items set for each connection
• Server/client specification
• Remote IP address specification
Server: Specify IP addresses of clients permitted to
connect.
Client: Specify remote Ethernet Unit (server) IP
address.
• Automatic FINS node address allocation:
Specify automatic allocation of client FINS node
addresses.
• Keep-alive:
Specify whether remote node keep-alive is to be used.
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
