Connection

Here we provide an overview of the procedures for connecting the robot controller to the network.
Network structure and cable specifications should be designed according to the materials provided by
the network interest group (ETG: EtherCAT Technology Group).

Network structure

EtherCAT is an open network that has been developed by German Beckhoff Automation GmbH and managed
by ETG (EtherCAT Technology Group).
The network corresponds to topologies with a lot of flexibility such as Star type, Line type, and Ring type, and
it is recommended to construct the network by Daisy-chained connection among them.

CAUTION
Network equipment such as switches can be used if it satisfies the requirements of the EtherCAT network.
However if the equipment is to be used in an environment where noise is a concern, such as a factory,
equipment that meets EMC industrial standards should be selected.
