Redundant Network Switches
PRS is the solution for a safe PROFIBUS DP Master redundancy concept, it provides switching over of the PROFIBUS line between two identical DP Masters. This avoids any galvanic contact between the DP Masters, they can therefore be configured with identical PROFIBUS addresses, making Multi Master mode unnecessary and excludes double address conflict.
The compact 24 Volt hat rail module contains the switching logic as well as an intelligent double DP Slave. PRS also allows the realization of very complex redundancy systems, i.e. in connection with PROFIBUS OPC servers or overlying Ethernet based cell networks.
