The New OPC Generation – OPC Unified Architecture. A key focus of the book is on the OPC Unified Architecture (OPC UA). The new OPC generation allows service oriented, multivendor, and cross-platform capable data and information exchange. The main objective of the new OPC generation Unified Architecture is to facilitate global interoperability and to define an information and data-exchange mechanism that is service oriented, multivendor, and cross-platform capable - from the field device on the shop floor to the ERP system on the factory level. OPC Unified Architecture (OPC UA) is the data ex- change standard for safe, reliable, manufacturer- and platform-independent industrial communication. It enables data exchange between products from different manufacturers and across operating sys- tems.
IEC is part of the overall OPC Unified Architecture (OPC UA) standard series and defines the information model associated with Data Access ( DA). OPC Unified Architecture (UA) is the new generation of OPC. The first parts of the OPC UA Specification part 8 (Data Access) released.
