Modicon M340 automation
platform
Modbus/TCP and EtherNet/IP network module
Presentation
The BMX NOC 0401 network module acts as an interface between the M340 PLC
and other Ethernet network devices via the Modbus/TCP and EtherNet/IP
communication protocols.
The standard format BMX NOC 0401 network module occupies a single slot in the
rack of the Modicon M340 platform.
This must be equipped with a Standard BMX P34 1000 or Performance
BMX P34 2pppp processor.
Functions
The BMX NOC 0401 module offers the following functions:
Modbus/TCP and EtherNet/IP protocols operating simultaneously.
Ring topologies on 2 Ethernet ports using RSTP (Rapid Spanning
Tree Protocol).
Priority of Ethernet packets using QoS (Quality of Service) service.
Automatic module configuration recovery using FDR (Faulty Device
Replacement) service.
Support for SCADA functions via the OPC protocol.
Embedded Web server for application monitoring and module diagnostics.
Sharing data between PLCs.
Network management using SNMP (Simple Network Management Protocol).

Description
The front panel of the BMX NOC 0401 module features:
A safety screw for locking the module in a slot in the rack.
A display block with 5 LEDs:
RUN LED (green): Operating status
ERR LED (red): Error detected
MS LED (green/red): Module status
NS LED (green/red): Network connection status
ETH STS LED (amber): Ethernet link status
Four RJ45 connectors for connection to the Ethernet network. The two bottom
connectors
3b support ring topologies (RSTP protocol).
Each RJ45 connector has two associated LEDs:
LNK LED (yellow): Ethernet link established
ACT LED (green): Transmission/reception activity
On the rear panel, 2 rotary switches for selecting the IP address module using one
of 4 assignment methods:
IP address defined by the Ethernet network BootP server
IP address configured by the application parameters
Default IP address
IP address defined by the position of the 2 rotary switches
