Product overview
2.1.2.3 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").
