Note
The supplement only supports CABLE REDUNDANCY
This supplement only supports cable redundancy. This means that fail safety exists only for
the cable sections. It applies to connections between the individual stations (controllers,
couplers and drives). Failures of individual terminals are not covered. Further details can be
found in the “Beckhoff Information System" under EtherCAT cable redundancy.
Cases of failure
The two possible failures are described in the example below.
In this example the supply line for coupler EK1100 is faulty. The EK1100 terminals continue to run despite
the cable failure. The “System Manager” indicates the failure as follows:
