Harmonizing Data Access:
Using the OPC Concentrator, several OPC Clients can access several OPC servers with different name spaces. Depending on the implementation of the vendor, OPC servers can provide a flat or a hierarchical name space. Also the structure of an OPC server's name space and the semantics to address variables in an OPC server significantly differs from vendor to vendor. Unifying resp. harmonizing the access to an OPC server's data is possible by usage of the OPC Concentrator.
Cascading of OPC Servers:
Data of several OPC servers is bundled and concentrated into one OPC server by usage of the OPC Concentrator. Data of several OPC Concentrator DLLs or several OPC Concentrator applications on several computers can be concentrated into another OPC Concentrator. That way, complex systems with a big number of OPC servers can be structured very well. Running the OPC Concentrators on different computers, which are interconnected via DCOM, can also improve the performance of the complete system.
