1588-aware High-Availability Cyber-Physical Production Systems

In this paper an architecture for High-Availability Cyber-Physical Production Systems with sub-microsecond synchronization capabilities is presented. The proposed CPPS nodes are based on cost-affordable components. These CPPS can deal with most of the challenges set by Industry for a massive adoption of the distributed computing philosophy in critical systems like Smart-Grids or Advanced Manufacturing Plants. In order to measure the resilience and accuracy of the 1588-aware high-availability network composed by these nodes, a concept-proof experimental setup has been developed. As it has been verified, although in a case of network failure, the synchronization recovers automatically and the offset between the master's and slaves' PPS signals is maintained below 1 μs.
