4.3 Use cable redundancy
The FC1028 EtherCAT card has independent EtherCAT interfaces that can be used for EtherCAT cable
redundancy. Cable redundancy offers resilience for the cabling. Interruptions of the EtherCAT
communication due to broken wires or unplugged LAN cables are avoided. Interference at the individual
terminals is not intercepted by the cable redundancy.
Fig. 7: Example configuration of a FC1028 with EtherCAT cable redundancy.
In the example configuration the hardware is wired as EtherCAT ring. For this EtherCAT ring two EtherCAT
masters of the FC1028 are occupied. This intercepts failures in the cabling beyond the C9900-K921 adapter
cable. In this way, for example, a wire break between the two EtherCAT couplers has no effect on the
EtherCAT communication.

Type Description
FC1028 Is the EtherCAT master in the example.
C9900-K921 Adapter cable for FC1028. Breakout cable with one ix-
Industrial
®
type A plug to 2 x Cat.6 RJ45 socket.
With the help of the adapter cable two EtherCAT masters
are executed from one x-Industrial
®
type A interface.
2 x EK1100 EtherCAT
coupler The first EtherCAT coupler forwards the EtherCAT signal to
connected EtherCAT Terminals and via the second
Ethernet interface to the second EK1100 EtherCAT coupler.
The second EtherCAT coupler is connected to the adapter
cable via the second Ethernet interface and in this way to
another EtherCAT master.
EtherCAT Terminals Any number of EtherCAT Terminals connected to the
EtherCAT coupler.
Requirements:
• For TwinCAT 2 you have to install and license the supplement TS622x | TwinCAT EtherCAT
Redundancy on the Embedded PC: https://www.beckhoff.com/TS622x
• In TwinCAT 3 the supplement is already included and only has to be licensed.
• Hardware wired as EtherCAT ring (see Fig.: Example configuration of a FC1028 with EtherCAT cable
redundancy).
Configure EtherCAT cable redundancy as follows:
