EnableRedundancy
Enables cable redundancy. The last EtherCAT slave is connected to another network interface card on the computer so all the slaves can be communicated even if one cable is broken.
Syntax
KsError EnableRedundancy(
BOOL Active
);
Parameters
Active: TRUE to enable, and FALSE to disable redundancy. By default, it is FALSE.
Return value
If the function succeeds, it returns errNoError
, otherwise an error code. For more information about the error code, see the KsError list.
Remarks
- This feature requires Cable Redundancy Package.
- This function must be called after Create and before Start.
- For more information about how redundancy works, see Concepts > EtherCAT cable redundancy.
- When Redundancy is enabled and redundant cabling is deployed, if a cable has been plugged from an EtherCAT slave, this slave can still be used but an alarm may occur.
