Applications

PLC with OPC UA Server

Data aggregation and interface abstraction

Aggregation of data from multiple sources in a central server (namespace aggregation)
Centralized application access to aggregation servers, avoiding numerous individual data sources
Extensive, flexible OPC UA service-based address space filtering down to OPC UA item level
Reduced configuration effort without individually configuration for each OPC UA data source and each OPC UA client
