Schneider Electric BMXNOE0100 M340 Ethernet TCP/IP Network

BMXNOE0100 Ethernet network module for the M340 rack

The BMXNOE0100 is a Schneider Electric product listed in the datasheet as: network module, Modicon M340, Modbus/TCP, 1 x RJ45, flash memory card. The BMXNOE0100 is an Ethernet communication module for the Modicon M340 platform. It adds an RJ45 Ethernet TCP/IP port with the services of Transparent Ready, such as Modbus TCP messaging and web pages, to a rack whose processor has no, or not enough, Ethernet. Seven Star LLC supplies the BMXNOE0100 in Oman and the GCC as an independent supplier based in Muscat.

Reading the reference: BMX is the M340 and X80 hardware family, NOE the Ethernet network module type, and 0100 the model; the datasheet title identifies it as Modbus/TCP with one RJ45 port and a flash card.

Technical specifications of the BMXNOE0100

Services and ports of the BMXNOE0100

Concept: Transparent Ready. Port: Ethernet TCP/IP RJ45 10/100 Mbit/s 1 twisted pair transparent ready class B30. Ethernet: 10BASE-T/100BASE-TX. Services: Bandwidth management; Data Editor (via PC terminal); FDR server; Rack Viewer; SNMP network administrator; Global Data; I/O scanning. Memory: Supplied Flash memory card (BMXRWSC016M). Memory use: Application saving; Activating the standard web server. Current consumption: 90 mA 24 V DC.

The module acts as an Ethernet node for the rack, handling Modbus TCP requests, an embedded web server for diagnostics and bandwidth control. A flash memory card carries the web pages and application backup.

Placement of the BMXNOE0100 in an M340 rack and its limits

The module goes into a standard slot of the rack after the processor; the number of communication modules a processor accepts is limited, so check the processor capacity (for example BMXP341000 supports a defined number of network modules).

If the project is on an M580 platform, the module is not the right component: M580 processors have their own Ethernet. The module remains the way to add Ethernet to M340 racks.

Selection checklist for the BMXNOE0100

• M340 rack and processor model support the module.
• Number of Ethernet modules vs processor limit.
• Firmware version of module and programming software.
• Network addressing plan.
• Need for web diagnostics or only Modbus TCP.
• Spare memory card.

Fitting and configuring the BMXNOE0100

Insert the module into a free slot with power off, connect the RJ45 cable and configure the IP parameters in the programming software. Use the reset button only when the manual procedure requires a cold restart.

Check the activity LED and the network statistics page to confirm traffic. Keep a copy of the memory card contents.

Typical applications of the BMXNOE0100 in Oman and the GCC

Common where a legacy M340 rack must connect to a SCADA system by Ethernet, such as pumping stations, water treatment and building automation in the region.

Dimensions, environment and approvals of the BMXNOE0100

The BMXNOE0100 weighs 0.2 kg. Mounting, derating and enclosure choices follow the environmental data below, which should be compared with the actual panel temperature and the dust and humidity of the site in Oman and the GCC.

Ambient temperature limits in the datasheet: 0 to 60 °C. Relative humidity: 10 to 95 % without condensation. Ingress protection: IP20.

A network module is easy to overlook in a project until the day a SCADA connection fails, so treat it as part of the system documentation. Record the IP address, subnet mask, gateway and the services enabled on the module, and keep the network drawing with the rack layout. When a module is replaced, the new unit has to be loaded with the same address data and, if used, the web pages from the memory card, so keep the card contents with the maintenance records. In plants with several racks, a naming convention that links the IP address to the rack number saves hours during fault finding. Where plant policy restricts open ports, review the services the module exposes with the IT or OT security team before connecting it to a wider network.

Information to send with an RFQ for the BMXNOE0100

• Full reference and quantity required
• Existing equipment, panel or rack it must fit
• Supply voltage, load or signal details of the application
• Required delivery location and timing
• Whether a spare, a replacement or a new installation

Site conditions in Oman for the BMXNOE0100

Control cabinets in Gulf plants often run hot, because many sit in outdoor kiosks or in rooms where air conditioning is not always reliable. Before you finalise the BMXNOE0100, check the permitted ambient range and any derating stated by the manufacturer against the real temperature inside your panel, and leave the recommended spacing around the device so that heat can escape. Long cable runs between the field and the marshalling cabinet are common on large sites, so confirm the signal types, wiring limits and earthing arrangement early in the design.

It also helps to standardise on a small number of part numbers across a project. Keeping a few spare BMXNOE0100 units on site in Oman shortens recovery time after a fault, and documenting configuration settings makes replacement faster for the maintenance team.
