Ethernet Unit Function Guide
Use the TCP/IP version of the FINS communications service (i.e., FINS/TCP).
FINS/TCP is a new function supported by these Ethernet Units (CS1W-
ETN21 and CJ1W-ETN21). It provides automatic recovery at the TCP/IP layer
from communications errors (such as packet loss) that occur during multilevel
routing. For CX-Programmer (version 4.0 or higher), FINS/TCP can be used
to directly connect to the PLC online. To use lower versions of the CX-Pro-
grammer with FINS/TCP, use FinsGateway (version 2003 or higher) as per-
sonal computer middleware.

Programmer with FINS/TCP, use FinsGateway (version 2003 or higher) as
personal computer middleware.
Depending on whether or not the connection will be within the same segment,
either use an IP address conversion method for dynamic IP addresses in the
UDP/IP version of the FINS communications service or use the TCP/IP ver-
sion of the FINS communications service.
It is possible to connect online to a PLC using the CX-Programmer from a
computer serving as a temporarily connected node or a permanent DHCP cli-
ent.
For CX-Programmer (version 4.0 or higher), FINS/TCP can be used to directly
connect to the PLC online. To use lower versions of the CX-Programmer with
FINS/TCP, use FinsGateway (version 2003 or higher) as personal computer
middleware.
