Recommendations about cabling
You may get detailed recommendations about cabling EtherCAT from the documentation
"Recommendations for the design of the infrastructure for EtherCAT/Ethernet", that is avail-
able for download at www.Beckhoff.com.
EtherCAT uses 4 wires for signal transfer.
Due to automatic cable detection (auto-crossing) symmetric (1:1) or cross-over cables can be used between
EtherCAT devices from Beckhoff.
