IP Addresses in FINS Communications
Related Products and Communications/Setting Methods
applications, such as mail servers, are normally allocated fixed IP addresses.
Ethernet Units in PLC systems are also allocated fixed IP addresses.
In communications involving previous models, multiple communications appli-
cations were configured on personal computers according to data accessing
uses, and the fact that no more than one UDP port number for FINS commu-
nications could be used on any given computer created a problem. This
Ethernet Unit provides a practical solution with an internal table that pairs
remote nodes (applications) with FINS node addresses, enabling dynamic
changes.
FINS nodes are allocated individually for each application on the computer,
and the respective FINS/UDP port numbers that are used are also allocated
individually. When FINS/UDP FINS commands are sent from individual appli-
cations to the Ethernet Unit, the respective remote IP addresses and remote
port numbers in the internal table are dynamically changed.
With this method as well, FINS nodes are allocated individually for each appli-
cation on the computer, and the respective FINS/TCP port numbers that are
used are also allocated individually. Each application is positioned with a
FINS/TCP client, and requests the opening of a connection with the Ethernet
Unit's FINS/TCP server. When the connection is established, the respective
remote IP address and remote port number in the internal table are dynami-
cally changed.
