I-10 Application Note EL9800
NOTE:
“Installed and ready to use devices”
NICs for which the “TwinCAT RT-Ethernet intermediate driver”* or the “Beckhoff Ethernet
driver”* was installed
“Compatible devices”
NICs which are com patible to the ”Beckhoff Ethernet driver”* but not installed yet
“Incompatible devices”
NICs which are not installed yet and accessible by the “TwinCAT RT-Ethernet intermediate
driver”*.
Only NICs which are shown within “Installed and ready to use devices” can be used for EtherCAT
purpose. To add a NIC to the “Installed and ready to use devices” list select the device and click
“install”.
*T he “Beckhoff Ethernet driver” shall be used for high real time requirements. A list of compatible
NICs are listed on

ml/ethercat_supnetworkcontroller.htm
The “TwinCAT RT-Ethernet intermediate driver” provides also an EtherCAT interface but without high
real time behaviour. This driver is sufficient for basic EtherCAT functionality.
Some applications/services (e.g. firewalls) may disturb access to the real time driver
interface. In first place disable all applications/services which access the selected network
card
