2.1 EtherCAT
EtherCAT (Ethernet for Control Automation Technology) is an industrial
Ethernet system that uses standard frames and the physical layers defined in
the IEEE 802.3 series of Ethernet standards. It was developed by Beckhoff
Automation GmbH.
EtherCAT is normally used for applications in which I/O data and parameters
need to be transmitted quickly.
In EtherCAT systems, the master is the only node in a segment that is
allowed to actively send EtherCAT frames. All other nodes simply forward
the frames. The last node in the segment will detect an open port and send
the frame back to the master.
The DX-NET-ETHERCAT-2 EtherCAT module works as a slave within the
EtherCAT network to which it is connected. The module contains the entire
EtherCAT protocol stack, including the CANopen-over-EtherCAT application
functions defined in DS301. By using EtherCAT, a bus topology containing
several hundred nodes can be implemented. In fact, the network‘s size is vir-
tually unlimited.
