PRS-PROFIBUS DP Redundancy Switch


Product is no longer available.

The PRS Redundancy Switch from KUNBUS is the ideal solution for DP Master redundancy by switching the PROFIBUS line between two identical DP Masters. This circumvents any galvanic contact between the DP Masters. They can be configured with identical PROFIBUS addresses, making Multi Master mode unnecessary while averting double address conflicts.

  • A double address conflict cannot occur, even if the failed DP Master is still active on the PROFIBUS level
  • Realization of very complex redundancy systems, i.e. in connection with PROFIBUS OPC Servers or overlying Ethernet based cell networks
  • PRS can be controlled via both integrated Ethernet connections if direct control via the PROFIBUS is not possible
  • There is no single point of failure with the PRS as the Master to Slave communication would continue without interruption if the device does develop a fault
