Master Redundancy Switch KUNBUS-PRS

Logo Master Redundancy Switch  KUNBUS-PRS

Product description

In times of just in time production as well as increased safety requirements plants have to imply redundancy. In case of failure of the operational system the complete control function must be taken over by a stand-by system. The optimal solution is PRS - PROFIBUS Redundancy Switch.

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.

PRS is a compact 24 V DIN rail module containing the switching logic as well as an intelligent double DP Slave.

The device allows the connection of two DP Masters and the 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 the device physically switches over to the stand-by Master, which seamlessly takes over the DP Slaves.
