Modicon M580 automation
platform
Modbus/TCP and EtherNet/IP network module
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 network module occupies a single slot in the
rack of the Modicon M580 platform. This module should be installed in the main
Ethernet backplane rack.
Functions
The BMXNOC0402 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 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
Combination of Ethernet modules and BMEP58 CPU
It is possible to combine Ethernet modules with the Modicon M580 CPU in order to
increase its connectivity.
In this example, the two NOC EtherNet/IP, Modbus/TCP network modules 5 are
linked to the BMEP58
●0●0 CPU module 4 by means of Ethernet Interlink cables 6.
Multiple combinations are possible:
4 BMEP581020 CPU
5 BMXNOC0402 EtherNet/IP, Modbus/TCP network module
6 Ethernet Interlink cable TCSECN3M3M1S4/1S4U
(1) The BMXNOC0402 communication module will be replaced by the BMENOC03●1 modules
during the 2nd quarter of 2014.
