DownloadEtherCAT Redundancy

Redundancy minimizes downtime
Even if a part of the EtherCAT network is disconnected, Cable Redundancy provides continuous connectivity.
This function allows you to fix disconnection without stopping the machines and production line where one controller provides both machine control and safety control.
