Notes on Extended Distance connection

Using components which support the Extended Distance connection, distances of up to 300 m can be bridged (for connections between two Extended Distance components). These components are marked with “extended distance” both in chapter “Technical data” and on the respective RJ45 sockets of the component. In the TwinCAT System Manager “Extended Distance” is part of the type designation (tab “General”, “Type”).

Topologies with Extended Distance components, distances up to 300 m

Distances of up to 300 m can be bridged between two Extended Distance components. Possible topologies are shown in the following figure.

Not permitted topologies with Extended Distance components

The EK1121-0010 EtherCAT junction cannot be used as a 2nd component because the EtherCAT port is not 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.
