Note
The supplement only supports CABLE REDUNDANCY
This supplement only supports cable redundancy. This means that fail safety exists only for
the cable sections. That means the connections between the couplers. Failures of individ
ual terminals are not covered.Further details can be found in the Beckhoff Information Sys
tem 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:
CX2020, CX2030, CX2040
