Omron CS1W-ETN21 Setting FINS/TCP Connections, Local Device Is Server, Local Device Is a Client

IP Addresses in FINS Communications			Section 5-2

	(1) The connection is established.	Local FINS node number B
Local FINS node number A
	(2) The local device (such as a personal	Local IP address S
Local IP address T	computer) sends notification that its
	FINS node number is A.
	IP address FINS node number transmission	Ethernet
	IP address FINS node number transmission

The FINS node number is converted for each connection number.

(3)The Ethernet Unit sends notification that its FINS node number is B.

(4)The internal node correspondence table is changed.

(5)It then becomes possible to send and receive FINS messages.

Setting FINS/TCP Connections

The procedure for setting FINS/TCP connections involves the items described below. The settings are made individually for each connection (numbers 1 to 16) under FINS/TCP settings in the Unit Setup.

Local Device Is Server

1,2,3... 1. Set the server.

2.Set IP addresses for connected devices.

If the option for protection by IP addresses is checked, set the IP address- es for clients where connections are permitted. (This can be omitted.)

3.Automatic FINS node address allocation:

If the client (generally a personal computer) supports FINS/TCP, and if it is to be used without setting a FINS node address, the value set here (from 239 to 254) can be allocated to the client.

Functions related to these settings are explained in detail in the Operation Manual Construction of Applications, SECTION 7 Using FINS Communi- cations to Create Host Applications. The default settings should normally be used.

Local Device Is a Client

1,2,3... 1. Set the client.

2.Set the IP addresses for the connection destination.

Set the IP address for the remote Ethernet Unit (i.e., the server) connected by FINS/TCP.

This setting must be made if this Ethernet Unit is to be used as a FINS/ TCP client.
