Connecting the CX-Programmer to PLCs Online via Ethernet
Connecting within the
Same Segment
Use the UDP/IP version of the FINS communications service (i.e.,
FINS/UDP). FINS/UDP is supported by many OMRON products and is com-
patible with earlier Ethernet Units (CS1W-ETN01/ETN11/ETN21 and CJ1W-
ETN11/ETN21). The CX-Programmer can be connected and used with
FINS/UDP.
Connecting through
Multiple Segments
Use the TCP/IP version of the FINS communications service (i.e., FINS/TCP).
It provides automatic recovery at the TCP/IP layer from communications
errors (such as packet loss) that occur during multilevel routing. For CX-Pro-
grammer, FINS/TCP can be used to directly connect to the PLC online.
Using Media with
Unreliable Connections,
Such as a Wireless LAN
Use the TCP/IP version of the FINS communications service (i.e., FINS/TCP).
It provides automatic recovery at the TCP/IP layer from communications
errors (such as packet loss) resulting from unreliable connections. For CX-
Programmer, FINS/TCP can be used to directly connect to the PLC online.
Connecting from a
Personal Computer with a
Dynamic Private IP
Address
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, FINS/TCP can be used to directly connect to the PLC
online.
Connecting through multiple segments, such as over the Internet:
Use FINS/TCP.
