Not permitted topologies with Extended Distance components
The EK1121-0010 EtherCAT junction cannot be used as a 2
an output port. The following figure shows not permitted topologies with Extended Distance components.

Topologies with Extended Distance- and Standard components, distances up to 100 m
If only one connection of the two Components is configured for Extended Distance, e.g. a connection
between a standard EtherCAT Coupler (EK1100) and an EtherCAT Coupler with Extended Distance
connection (EK1101-0010), the maximum distance between the stations is 100 m. In the following figure the
standard components are marked with a "*". Standard components are detected automatically. The
parameterization of the EtherCAT ports is not necessary. Examples of possible topologies are shown in the
following figure.
