Modicon X80 EtherNet/IP switch module — slot 0 of the rack
The Schneider Electric BMENOS0300 is a network option switch module in the Modicon X80 family, built to sit at the head of an X80 rack and carry EtherNet/IP traffic between the CPU, distributed drops and a service laptop. Three physical ports are wired internally as EtherNet/IP — two for the device network daisy chain and one dedicated as the service port — so the same module handles both plant traffic and engineering access without a second NIC on the laptop. Front-face diagnostics match the X80 convention: a green RUN LED for module active, a red ERR LED for module fault, a green/red Mod Status for the CIP stack, and a green/red Net Status for the network state — the four lamps any commissioning engineer will read first.
Thermal envelope and where it will live in the panel
Operating air temperature is 0…60 °C, which is the column to read when sizing cabinet ventilation — storage is separate at −40…85 °C and is the limit that governs handling, not running. Operating altitude is rated to 2000 m and transport to 3000 m; siting above 2000 m on a permanent basis is outside the rating and needs a re-derate against the rack vendor's altitude curve. The module ships as a standard X80 format with IP20 protection, overvoltage category II, and 95 % non-condensing humidity — consistent with an enclosed control cabinet rather than a field-side enclosure.
Compliance paperwork on the nameplate
The unit carries CE marking and is declared against 2014/35/EU (low voltage) and 2014/30/EU (electromagnetic compatibility) — the LV + EMC pair is what closes the EU technical-file loop for this slot.
Sourcing posture
Lifecycle status is current, the backplane supply is 24 V and the module draws 3.3 W at 25 °C / 4.5 W at 60 °C. Order against an RFQ quoting MPN BMENOS0300 so rack power budget stays traceable.
