3.6 Installing the fieldbus connection
An RJ45 plug is used in order to establish a connection to the EtherCAT field
bus.
Generally, connection cables with RJ45 plugs for ETHERCAT are available as
standard ready-for-use cables. They can also be prepared individually. This
will require the connections shown below (pinout).
