Anybus Communicator - EtherNet/IP to EtherCAT MDevice
5.2. How the Communication Works
The Communicator enables communication, data exchange, between one or more nodes connected to a
EtherCAT subnetwork and a client device connected to a high level network.
Figure 3. Process data traffic overview
For example:
• The client device can be a PLC or a PC.
• The node(s) can be a sensor, scanner, industrial robot or sniffer.
The Communicator main task is to cyclically send the process data objects that the nodes(s) are configured to
execute, in order to request and transfer process data.
Input Process Data
Figure 4. Process data traffic from nodes to client
Receive process data from the EtherCAT subnetwork nodes and make the process data available on the
EtherNet/IP interface and for the high level network client device.
The process data is specified when the EtherCAT network is scanned and the nodes(s) configuration is uploaded
to the Communicator.
