17-1 Features and Specifications
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).
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 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.
