17-1-1 Ethernet Option Board Function Guide

Overall system configuration example
Ethernet Option Board provides receiving commands by OMRON standard protocol FINS for CP1E
programmable controllers. The Ethernet Network Interface allows you to easily connect CP1E Program-
mable Controllers onto new or existing Ethernet network and upload/download programs, communicate
between controllers (do not support real-time scanning I/O on Ethernet Option Board).
Connecting from a computer with a
dynamic private IP address: Use
FINS/TCP or FINS/UDP.
CX-Programmer
FINS
Note 1 Please use CX-Programmer version 9.12 or higher (CX-ONE version 4.1 or higher).
2 Use the Web browser to set the CP1W-CIF41.
3 NS-series HMI cannot use CP1W-CIF41 through Ethernet.
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 compatible 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-Programmer, 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 unreli-
able connections. For CX-Programmer, FINS/TCP can be used to directly connect to the PLC online.
