Why Engineers Specify This Model
- Dual-Port Ethernet Switch: The integrated 2-port switch enables daisy-chain or star topology without an external switch, reducing panel footprint and wiring cost.
- Simultaneous Multi-Protocol Support: Runs Modbus TCP/IP and EtherNet/IP concurrently, allowing a single module to serve both legacy SCADA and modern EtherNet/IP devices.
- Embedded I/O Scanner: Polls up to 64 remote Ethernet I/O devices autonomously, offloading the CPU and ensuring deterministic scan cycles.
- Built-in Web Diagnostics: Engineers can access real-time module status, network statistics, and I/O data via any standard browser — no additional software required.
- Hot-Swap Capable: Supports online module replacement on M340 racks with redundant power, minimising planned downtime during maintenance windows.
- Unity Pro / EcoStruxure Machine Expert Compatible: Full configuration and diagnostics within Schneider’s standard engineering toolchain — no third-party drivers needed.

Application-Specific FAQ
Q: Can the BMXNOC0401 replace the BMXNOE0100 in an existing M340 rack?
A: Yes. The BMXNOC0401 is the successor to the BMXNOE0100 and is backward-compatible with existing M340 racks. It adds a second Ethernet port and enhanced I/O scanner capacity. Unity Pro configuration migration is straightforward.
Q: Does this module support DHCP or does it require a static IP?
A: Both modes are supported. The module can be configured for DHCP, BOOTP, or static IP assignment via Unity Pro or the embedded web server.
Q: How many Modbus TCP/IP connections can run simultaneously?
A: The BMXNOC0401 supports up to 64 simultaneous TCP connections, which can be allocated across Modbus TCP/IP server/client and EtherNet/IP adapter/scanner roles.
Q: Is the module compatible with EcoStruxure Machine Expert (formerly SoMachine)?
A: The BMXNOC0401 is a Modicon M340 module and is configured via Unity Pro or EcoStruxure Control Expert. EcoStruxure Machine Expert targets Modicon M221/M241/M262 platforms and is not applicable here.
Q: Can I use this module for remote I/O over Ethernet?
A: Yes. The embedded I/O scanner function allows the BMXNOC0401 to poll up to 64 remote Ethernet I/O heads (e.g., Advantys STB, Momentum) directly, without additional gateway hardware.
