PRS

PRS is a compact 24 Volt hat rail module with two DP Master connections and one PROFIBUS connection to the DP Slaves. The Switch controls the status of the operational DP Master system on the PROFIBUS protocol and application level. In case of failure of the operational Master PRS physically switches over to the stand-by Master, which seamlessly takes over the DP Slaves.

• A double address conflict cannot occur, even if the failed DP Master is still active on the PROFIBUS level
• Realisation 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
