Presentation
The BMXNOC0402 (1) network module acts as an interface between the M580 PLC
and other Ethernet network devices via the Modbus/TCP and EtherNet/IP
communication protocols.
The standard format BMXNOC0402 (1) network module occupies a single slot in the
rack of the Modicon M580 platform. This module has to be installed in the main
Ethernet + X-bus backplane rack.
Functions
The BMXNOC0402 (1) module offers the following functions:
b Modbus/TCP and EtherNet/IP protocols operating simultaneously
b Ring topologies on 2 Ethernet ports using RSTP (Rapid Spanning Tree Protocol)
b Priority of Ethernet packets using QoS (Quality of Service) service
b Automatic module conguration recovery using FDR (Fast Device Replacement)
service
b Embedded Web server for application monitoring and module diagnostics
b Sharing data between PLCs
b Network management using SNMP (Simple Network Management Protocol)
Description
The front panel of the BMXNOC0402 (1) module features:
1 A screw for locking the module in a slot in the rack.
2 A display block with 5 LEDs:
v RUN LED (green): Operating status
v ERR LED (red): Error detected
v MS LED (green/red): Module status
v NS LED (green/red): Network connection status
v ETH STS LED (amber): Ethernet link status
3 Four RJ45 connectors for connection to the Ethernet network. The two bottom
connectors 3a support ring topologies (RSTP protocol).
Each RJ45 connector has two associated LEDs:
v LNK LED (yellow): Ethernet link established
v ACT LED (green): Transmission/reception activity
(1) The BMXNOC0402 communication module will be replaced by the BMENOC03p1 modules
during the 2nd quarter of 2014.
