	The following settings can be made for each connection number.
	Item	Contents	Default
	FINS/TCP Mode	For each connection number, this setting specifies	Server
		the Ethernet Unit for use as either a server or a cli-
		ent.
		• When the Ethernet Unit is used as a server:
		The Ethernet Unit opens a connection with that
		connection number and waits for service requests
		(FINS commands) from clients. Connection num-
		bers are used in ascending order and allocated to
		clients in the order connections are made.
		• When the Ethernet Unit is used as a client:
		The Ethernet Unit establishes a connection with
		the server set as the destination IP address. Once
		the connection has been established, FINS/TCP is
		used for FINS communications.
	IP Address	• When the Ethernet Unit is used as a server:	0.0.0.0
		If the option is selected to use IP addresses to pro-
		tect, set the IP addresses as required at clients
		from which connection is permitted. If not set for
		those connections, the default setting of 0.0.0.0
		can be used.
		• When the Ethernet Unit is used as a client:
		Set the IP address for the remote Ethernet Unit
		(i.e., the server) that is to be connected by FINS/
		TCP. It is required that an IP address be set for the
		remote Ethernet Unit.

		node address. Then, when a FINS command	1 to 16
		arrives, the number set here (from 239 to 254) will
		automatically be allocated as the client's FINS node
		address.
		For details on automatic allocation of FINS node
		addresses, refer to the Operation Manual Construc-
		tion of Applications.
	keep-alive	For each connection number, set whether or not the	Use
		remote node connection check function is to be
		used for the FINS/TCP server and client.
		If the keep-alive box is checked here, then, when
		the remote node goes without responding for longer
		than the monitor time set in the Setup, the connec-
		tion will be terminated. If a remote node turns OFF
		without warning, the connection will remain open
		indefinitely, so this option should be used whenever
		possible.

For details, refer to SECTION 6 FINS Communications Service in the Opera- tion Manual Construction of Networks.
