For Application which must fulfill high requirements in regards to availability, the CPU1517H is available.
Both controllers are connected to a PROFINET IO-ring, in order to access the IO-Stations. Both controllers synchronize each via dedicated synchronization modules. In case the primary CPU fails the back-up CPU takes over the control. No data will be lost and the process continues without interruption.
The ring architecture ensures in case of a cable fault that all network participants are still accessible.
The Engineering corresponds to Engineering of a standard CPU. The synchronization of the programs and data are handled by the TIA-Portal and the redundant controllers, no additional user action required.
