2.9.7 Network Module for DeviceNet
DeviceNet represents a cost-effective solution for the network integration of low-level terminal
equipment. Up to 64 devices including a master can be integrated in one network. For the data
exchange a cable with two shielded twisted-pair cables is used.

2.9.8 Network Module for CANopen
CANopen is an “open” implementation of the Controller Area Network (CAN), which is defined in
the EN50325-4 standard. CANopen offers cost effective network communications with
fault-resistant network structure where components of different manufacturers can be inte-
grated quickly and easily. CANopen networks are used for connecting sensors, actuators and
controllers in a variety of applications. The bus uses inexpensive twisted-pair cabling.

The DeviceNet slave module FX2N-64DNET can be used
to connect FX
2N,FX2NC and FX3U programmable control
-
lers to a DeviceNet network.
The FX2N-64DNET can communicate to the master by
the master/slave communication (using the master/slave
I/O connection), and to other nodes supporting the UCMM
connection by client/server communication.
The communication between the programmable control
-
ler and the internal buffer memory of the FX
2N-64DNET is
handled by FROM/TO instructions.

In addition to real-time capabilities and high-speed data
transfer at rates of up to 1 Mbps the CANopen module also
shines with high transfer reliability and simple network
configuration. Up to 120 words of data can be sent and
received as process data objects (30 PDOs).
