Abstract
System and method for synchronizing information model changes between hierarchical systems of a smart factory are disclosed. A model generator instantiates objects for an aggregated information model for each of a plurality of subsystems in the smart factory based on an OPC UA standardized model. A synchronization engine maintains a global timestamp variable for a last successful synchronization performed by a parent OPC UA server for syncing to a second aggregated information model instance stored in a lower level OPC UA server. Model nodes are annotated with a node-wise timestamp in response to a modification to the node. All nodes subject to modification are pushed to a priority queue as a serialized node set format having annotation extensions that include synchronization-relevant data. The first and second aggregated information model are synchronized by updating nodes with the synchronization-relevant data.
