Product Overview
Downtime on a control network rarely announces itself. A single failed switch can stall an entire Modicon rack, and every idle hour carries a cost. The Schneider Electric 140ENETSW01 is an eight-port Ethernet switch built for the Modicon platform. It carries bus communication between Schneider Electric devices over Modbus TCP/IP, so your control layer keeps talking without interruption.
This is a practical, rack-mounted module. It weighs 1.13 lbs (0.51 kg) and measures 279 mm wide, 356 mm high and 203 mm deep. For plants running legacy Modicon systems, keeping a spare on the shelf is cheaper than waiting on a breakdown.
Technical Specifications
Each port runs at 10/100 Mbps, giving you eight simultaneous Ethernet connections in one slot. The module draws 5 V DC at 3A, a modest load that keeps power budgeting simple inside the rack.

Where It Fits in the Plant
Oil and gas facilities often run mixed Modicon estates across well pads, compressor stations and pipeline interfaces. The 140ENETSW01 links those devices over Modbus TCP/IP, so data moves between controllers and supervisory systems without extra gateways. In a water treatment skada, the eight ports absorb PLCs, HMIs and remote I/O on one switch, reducing the number of separate network devices you must power and maintain. For packaging lines, the same eight-port layout keeps machine controllers and drives on a single segment, which simplifies troubleshooting when a node drops offline.
Installation and Setup
The 140ENETSW01 is rack-mounted, so plan the slot alongside your existing Modicon modules and confirm the 5 V DC supply is available on the backplane. Keep the operating envelope in mind: 0°C to 55°C with 5% to 95% non-condensing humidity. Cabinets that run hot or damp will shorten service life, so check airflow before commissioning. Each port has its own LED indicator, which makes link and activity checks quick during startup.
Integration Note
Wiring into a Modbus TCP/IP network may require an external gateway or connection module depending on your existing architecture. Confirm cables and gateways with your supplier before installation.
Maintenance and Cost Control
LED indicators per port let technicians spot a failed link without pulling the module. That shortens diagnosis time and protects maintenance budgets. Because the unit draws only 3A at 5 V DC, it adds little to cabinet heat and power cost. Keep a spare 140ENETSW01 on hand: a fast swap beats expedited freight and lost production.
