	used when TCP is used for the FINS communica-
	tions service. It corresponds to a socket in the socket
	services. Up to 16 can be used at a time, and they
	are identified by connection numbers 1 to 16. The
	Ethernet Unit can thus simultaneously execute the
	FINS communications service by TCP with up to 16
	remote nodes.

	set for that IP address will be denied.

	FINS commands) from specific nodes from affecting
	the PLC.
