The Omron E3X-CIF11 is a CompoWay/F serial communications unit built for the E3X-DAN fiber amplifier family, used to host the amplifier on a CompoWay/F master so threshold and incident-level data can be read or set from the controller side. It ships in bulk packaging and carries a mature-stage listing on the E3X line, which tracks with the long-running fiber-amp platform it attaches to rather than a newly released accessory.
Panel-side notes
As a CompoWay/F host unit on an E3X-DAN amplifier, the E3X-CIF11 inherits the amplifier's point-to-point wiring practice — one comm line per amplifier, address set on the amplifier itself, and the controller polled as the master on the CompoWay/F segment. Because the function is a dedicated CompoWay/F comm module for the E3X-DAN amplifier (not a generic serial splitter or a CC-Link / DeviceNet gateway), specifying it into a panel means the controller side must already be running a CompoWay/F master; a panel built around a different fieldbus will not pick this unit up without a bridge.
Sourcing the part
For a BOM line that already calls out E3X-CIF11 against an E3X-DAN amplifier, the cleanest path is to quote it to order with the matching E3X-DAN amplifier code and confirm the CompoWay/F address scheme on the controller side; no cross-reference to a different comm module is warranted because the function is fixed to CompoWay/F on the E3X-DAN line.
