The Omron CP1W-ETN61 is a CP1W-series Ethernet link adapter in a Box package, listed as Accessory Type Link Adapter and specified for Ethernet on the CP1 Series host family — it slots onto a CP1L or CP1H PLC to give the rack Ethernet connectivity without changing the CPU.
Production status
Production status on record is current per the lifecycle record, so the part is still being built and can be specified into an active BOM line.
Where the class is used
As a CP1W link adapter, the module hangs off the side of a CP1L or CP1H CPU and bridges that small brick-style PLC onto an Ethernet network for programming, HMI polling, or peer-to-peer data — the role it plays in the panel is communications, not I/O.
