If the cable redundancy function is enabled, always write a program to confirm that the
network is in the cable redundancy status. If the program is not written, you cannot
check that the network is not in the cable redundancy status due to a disconnection on
the ring topology.
Use the _EC_RingBreaking system-defined variable to confirm that the network is in
the cable redundancy status.
Version Information
The cable redundancy function can be used with project unit version 1.40 or later.
