This section describes how to install EtherCAT networks.
Supported Network Topologies
The EtherCAT port on the CK3M-series Programmable Multi-Axis Controller can be connected using
daisy chain connections with no branching, or with branching connections using Junction Slaves.
Examples of topology without branching and with branching (Junction Slaves) are shown below.
